The Automatic Linear Vial Washing Machine (Model: LI-VW) by Lodha Pharma is a high-speed, fully automatic vial cleaning machine where glass vials travel in a straight-line path — a linear tunnel — from the infeed loading point through multiple washing stations and out to the discharge end. The term "linear" refers to this continuous, straight-line movement of vials through the machine, as opposed to a rotary design where vials travel in a circular path. The linear tunnel design is especially effective because it physically and hygienically separates the feeding zone (where unwashed vials enter) from the discharge zone (where clean vials exit) — a key GMP requirement to prevent cross-contamination between dirty and clean containers.

Manual rinsing of glass vials is not acceptable in any GMP-compliant manufacturing environment — and for very good reason. Glass vials arrive from the manufacturer with invisible contaminants including glass dust, silica particles from the forming process, atmospheric dirt, microbial deposits, and moisture. When you fill any product — an injectable antibiotic, an Ayurvedic herbal liquid, or a cosmetic hyaluronic acid serum — into an unclean vial, those contaminants go directly into your product. For injectables, this is a serious patient safety risk. For Ayurvedic and cosmetic products, this causes product failure, consumer complaints, batch rejections, and damaged brand reputation. The Linear Vial Washing Machine eliminates all of this with a fully automated, validated, multi-stage washing process that no manual method can replicate — consistently, at high speed, and at scale.

The LI-VW Linear Vial Washing Machine is specifically optimized for round (cylindrical) glass vials — which are the standard format used across pharmaceutical injectables, Ayurvedic liquid preparations, and cosmetic serum vials in the 2 ml to 30 ml size range. The machine's pocket conveyor system, washing needle alignment, and inversion mechanism are all precisely calibrated for round vial geometry. Square, rectangular, or irregularly shaped containers require different machine configurations. If your product line uses round glass vials — which is the overwhelming majority of pharma, Ayurvedic, and cosmetic vial applications in India — the LI-VW is perfectly suited for your needs.

The process is elegant, automated, and thorough. Here is exactly what happens from the moment a vial enters the machine to the moment it exits clean: Vials are loaded onto the SS wire mesh conveyor either through an automatic feed conveyor or manually pushed from a feed table. As the Geneva mechanism (an intermittent motion system) rotates, each vial is picked up and inverted neck-down into a pocket on the conveyor. In this inverted position, the washing needles enter the neck of the vial from below and deliver pressurized jets of washing media — purified water, DM water, WFI, or compressed air — directly into the interior of the vial. The vial travels intermittently through the linear tunnel, stopping briefly at each washing station for a dedicated wash cycle. After all washing and air blow-off cycles are complete, the vials are automatically reinverted back to their upright position and discharged onto a tray or turntable for transfer to the filling station — clean, dry, and ready for filling. A special clutch device stops the machine automatically if any vial is overturned or is of incorrect diameter, preventing damage and contamination.

The machine performs three-cycle rinsing as the standard configuration, with the flexibility to customize washing sequences based on your specific GMP protocol and product requirements. A typical washing cycle sequence includes:
  • Cycle 1: Recycled/reclaimed water (pre-wash to remove bulk contamination)
  • Cycle 2: Demineralized (DM) water or purified water (secondary wash)
  • Cycle 3: WFI — Water for Injection (final rinse for injectable-grade cleanliness)
  • Final Stage: Compressed air blow-off (to remove residual water from the vial interior)
Both internal and external surfaces of each vial are washed. Solenoid valves control the water jets — they open only during the active washing operation, which conserves costly WFI and purified water. The washing sequence can be fully customized to match your validation protocol and regulatory requirements.

The Geneva mechanism is an intermittent motion drive system — it moves the vial conveyor in precise, controlled steps rather than continuously. This means each vial pauses at each washing station for a defined period of time before moving to the next station. This controlled dwell time ensures that the washing needles have sufficient time to penetrate the vial neck, deliver the washing media under pressure, and fully clean the interior before the vial moves forward. Without this intermittent motion, vials would rush past the washing needles too quickly for effective cleaning. The Geneva mechanism is what makes the linear washer both fast and thorough — a combination that's critical for high-volume pharma and Ayurvedic injectable manufacturing.

Both. The LI-VW washes vials internally through pressurized needle jets that enter the vial neck, and externally through surrounding jets that clean the outer glass surface simultaneously. This dual internal-external washing is critical because: For pharmaceutical injectables, any particle or residue on the outer vial surface can contaminate the filling environment and affect vial integrity after sealing. For Ayurvedic liquid vials, an externally dirty vial can cause labeling adhesion issues and create a poor appearance on the final product shelf. For cosmetic serum vials, external cleanliness is directly visible to the end consumer and is part of the premium product presentation your brand promises.

The machine is equipped with a special clutch device that automatically stops the machine if a vial is overturned or if a vial of incorrect diameter enters the pocket. Additionally, emergency stop switches are fitted at both the infeed and outfeed sides of the machine for immediate operator intervention. This fail-safe system prevents vial breakage, glass contamination of the washing media, and damage to the washing needles — protecting both the machine and the batch quality. This is especially important for Ayurvedic and cosmetic manufacturers who may run multiple vial sizes on the same line.

Yes. The Automatic Linear Vial Washing Machine by Lodha Pharma is designed and manufactured in full compliance with current Good Manufacturing Practice (cGMP) standards. The key compliance features include: All parts in contact with the washing zone and jets are made from SS 316 stainless steel — the pharmaceutical-grade material standard required by Schedule M (Indian GMP), WHO-GMP, and AYUSH regulations. The machine frame and non-contact structure are built in SS 304. The linear tunnel design maintains physical separation between the dirty infeed zone and the clean outfeed zone — a critical GMP requirement. The solenoid valve-controlled washing sequence is repeatable, documentable, and validatable. The machine is suitable for IQ/OQ/PQ validation documentation for regulatory submissions. For AYUSH-licensed Ayurvedic manufacturers producing herbal liquids, classical formulations, or therapeutic oils in glass vials, this machine meets the container cleanliness requirements before filling. For Schedule M and WHO-GMP certified pharma plants, the LI-VW is compliant for both sterile and non-sterile injectable vial washing lines.

This is where the linear tunnel design provides a critical GMP advantage. The machine is built so that the feeding zone (where unwashed vials enter) and the discharge zone (where cleaned vials exit) are physically separated and isolated within the tunnel structure. Unwashed vials cannot come into contact with — or even share the same airspace as — already-washed vials. This separation is a fundamental requirement of GMP-compliant injectable manufacturing and is one of the key compliance checkpoints during drug authority inspections. Additionally, all mechanical drives are isolated and separated from the washing zone, preventing lubricant or mechanical contamination from reaching the vials.

Yes. The LI-VW is fully validatable. The washing sequence — including water pressure, solenoid valve timing, washing media type at each station, dwell time per station, and air blow-off parameters — can all be documented, fixed, and repeated consistently across production batches. Your QA team can perform IQ (Installation Qualification), OQ (Operational Qualification), and PQ (Performance Qualification) using standard particulate matter testing, water conductivity testing, and endotoxin testing on post-wash vial samples. Lodha Pharma provides technical documentation support for validation activities. For WHO-GMP audits, the machine's cGMP construction, SS 316 contact parts, and validated washing sequences directly satisfy auditor requirements for vial cleanliness.

Absolutely — and it's an essential investment for any AYUSH-licensed injectable Ayurvedic unit. Herbal liquid injectables, therapeutic oils, and distillate-based preparations filled in glass vials must meet the same container cleanliness standards as allopathic injectables when it comes to particulate matter and microbial contamination. Glass particles from vial manufacturing, if not removed by a validated washing process, can end up in your Ayurvedic injectable product — making it unsafe for administration. The LI-VW's three-stage wash cycle with WFI final rinse and compressed air blow-off ensures your vials are particle-free and contamination-free before filling. If your Ayurvedic unit is scaling up production volume beyond what a semi-automatic multijet washer can handle, the LI-VW is the natural next step.

Yes, perfectly. Cosmetic glass serum vials in the 2 ml to 30 ml range are exactly the container type this machine is designed for. For cosmetic manufacturers, the reasons to use a proper automated vial washer are compelling: a particle or glass dust contamination inside your vitamin C or hyaluronic acid serum will be visible in the final product, leading to customer returns and social media backlash. A cloudiness caused by residual water deposits or microbial contamination inside an unwashed vial can destabilize your active ingredients and reduce shelf life. The LI-VW ensures every single vial your cosmetic serum is filled into is internally and externally spotless. For premium cosmetic brands and cosmetic exporters, this level of cleanliness is non-negotiable.

Yes. With appropriate change parts for different vial sizes (2 ml to 30 ml), the same LI-VW machine can wash vials for both sterile injectables and non-sterile oral liquids. The key difference is in the washing sequence — injectable vials require WFI in the final rinse station, while oral liquid vials may use purified water or DM water. Since the washing sequence on the LI-VW is fully configurable through solenoid valve programming, your team can set up and save different washing protocols for different product lines. This makes the LI-VW a highly versatile and cost-efficient investment for multi-product pharma facilities running both injectable and oral liquid lines.

Yes. The Automatic Linear Vial Washing Machine is not restricted to human pharmaceutical applications. Veterinary injectable manufacturers, nutraceutical liquid vial producers, and biotech fermentation product manufacturers all use linear vial washers for the same fundamental reason — glass vials must be thoroughly cleaned before filling regardless of the end application. The machine's cGMP-compliant construction, SS 316 contact parts, and validated washing sequences make it suitable for any regulated manufacturing environment where glass vial cleanliness is a quality and compliance requirement.

The machine offers two loading options designed to minimize manual handling and reduce manpower requirements:
Option 1 — Automatic Feed Conveyor Loading: Vials are fed directly from an upstream feed conveyor onto the SS wire mesh conveyor of the washing machine. This is the preferred option for fully integrated production lines where the washing machine is connected inline with a depyrogenation tunnel or filling machine.
Option 2 — Manual Push from Feed Table: An operator pushes vials from a feed table onto the SS wire mesh conveyor. This option is suitable for stand-alone washing machine setups or where the production line is not fully automated.
In both cases, once the vials are on the conveyor, the automatic loading mechanism feeds vials into pockets without manual arrangement — saving significant operator time and reducing human contact with the vials before washing.

After the washing and air blow-off cycles are complete, the Geneva mechanism reinverts the vials from the neck-down position back to their upright, vertical position. The clean vials are then automatically discharged onto a tray or a turntable (the turntable option is available as an optional feature). From the turntable or tray, vials transfer to the depyrogenation tunnel (for injectable lines) or directly to the filling station (for non-sterile lines). The entire discharge process is automated, ensuring no manual contact with the cleaned interior of the washed vials — maintaining the integrity of the washing process right up to the filling station.

The machine is designed for ease of maintenance with the following key routine tasks: The washing needles should be inspected regularly and cleaned to prevent mineral scale or biofilm buildup from purified water or DM water deposits. The solenoid valves that control water jet timing should be tested periodically for correct operation. The SS wire mesh conveyor and pocket system should be visually inspected for wear or misalignment. The imported pumps — which are provided with the machine to ensure consistent water pressure — should be serviced as per the manufacturer's schedule. The filter housings and cartridges on the water supply lines should be replaced as per your maintenance SOP. Beyond these routine checks, the machine's robust all-SS construction, isolated mechanical drives, and heavy-duty SS base structure are built for years of low-maintenance, continuous production use.

The Automatic Linear Vial Washing Machine is suitable for 2 ml to 30 ml round glass vials with the appropriate change parts. Size changeover involves replacing the pocket set on the conveyor system and adjusting the needle alignment to match the new vial neck diameter. Lodha Pharma supplies complete change part sets for each vial size the machine will handle. All change parts are manufactured from SS 316 to maintain GMP compliance. A trained operator can typically complete a size changeover in under an hour, and the machine's simple structure and quick changeover design are specifically highlighted as key operational features — minimizing downtime between product or size runs.
