Common types include vial liquid filling machines, vial powder filling machines, aseptic vial filler cappers, peristaltic pump-based vial fillers, PLC-based vial fillers, multi-head models (such as four-head, six-head, or eight-head), automatic vial fillers with stoppering and capping, and high-speed or monoblock systems that integrate filling, stoppering, and sealing.

Production rates vary by model and configuration. Liquid filling models typically range from about 40 vials per minute (two-head) up to 250 vials per minute (twelve-head). Powder filling machines can achieve up to 100–200 vials per minute depending on single- or double-track designs, with integrated high-speed lines reaching higher outputs.

Most machines accommodate vial diameters of 15–70 mm and heights of 25–140 mm. Liquid fillers generally support fill volumes from 2 ml to 250 ml, while powder fillers handle doses from approximately 50 mg to 10 grams, with easy changeovers for different sizes.

Liquid filling machines typically achieve accuracy of ±1% (or better in some configurations). Powder filling machines deliver volumetric accuracy of about ±2–3%, depending on powder bulk density and uniformity. Advanced models may use servo controls or check-weighing for even tighter precision.

They operate under laminar airflow in Class 100 (ISO 5) cleanroom environments, feature “No Vial – No Filling” sensors, use SS 316L contact parts that are autoclave-compatible, and often include nitrogen flushing, built-in stoppering, and optional isolator or RABS integration. Many support CIP/SIP and provide IQ/OQ documentation.

Sterilized vials are fed via an unscrambler or turntable onto a conveyor and positioned under filling nozzles by a star wheel. Volumetric piston or peristaltic pumps dispense the liquid accurately; nozzles rise after filling. Vials then move to rubber stoppering and capping stations before outfeed.

Sterile powder is agitated in a hopper for uniform density. A vacuum-pressure powder wheel with adjustable pistons meters precise doses into vials. Excess powder is removed by a doctor blade, and low-pressure air or nitrogen flushes the dose into the vial, followed by immediate rubber stoppering.

They provide high throughput, precise dosing with minimal waste, reduced human intervention for better sterility, compact cGMP-compliant designs, easy integration into complete lines (washing, sterilizing, capping, labeling), variable speed control, digital counters, and lower operational costs through efficiency and validation support.

Yes. Machines can be tailored for specific production needs, power requirements, and configurations (e.g., number of heads, pump type, or isolator integration). Adinath International supplies cGMP-compliant vial filling solutions worldwide to numerous countries across Asia, Europe, Africa, the Americas, and the Middle East.
