Vial Filling Machine is a technically sophisticated device that accurately fills and dispenses liquid or powder materials. As the name implies, it fills “vials.” These are prefabricated little bottles that are often made of special polymers or borosilicate glass. The open handling of the containers between cleaning and sealing is a crucial step in this process, which is why the strictest environmental hygiene regulations are applicable.
The pharmaceutical sector makes considerable use of vial filling machines to fill vials with pharmaceutical substances. These incredibly robust devices are made to carry out the exact process of quickly filling vials. In order to satisfy the expectations of the pharmaceutical business, vial filling machines also have several filling heads, which allow them achieve a higher filling rate and increased productivity. Vial-filling machines come in a variety of forms that are appropriate for various uses in the pharmaceutical sector.
The main machine, unscrambler, conveyor, stopper feeding bowl, and scrambler make up the vial liquid filling machine. The vials are moved via the conveyor belt to the filling station, where the machine is filled with liquid. Liquids or fluids of different viscosities are filled into vials using vial liquid filling equipment. The pharmaceutical sector makes extensive use of these devices to guarantee accurate vial filling. The liquid filling machine for vials uses the volumetric concept and diving nozzle to deliver sterile and accurate filling operations.
The incoming dry vials (sterilized and siliconized) are fed through the unscrambler and suitably guided on the moving Delrin slat conveyor belt at the required speed of the correct placement below filling unit.
The filling unit consists of Filling Head, Syringes & Nozzles; Syringes & Nozzles are made of AISI SS 316L materials. A Star Wheel is provided which holds the vial during filling operation. A sensor is provided for ”No Vial-No Filling” operation. Syringes are mounted on eccentric block and driving through bottom main gear box. Volume can be increase & decrease by increasing or decreasing stroke length of piston as per filling size. Syringes is having non return valve for sucking and delivering situation to avoid volume variation. Liquid reaches to filling nozzles through silicon transparent pipe. Nozzles having up & down movement with help of cam mechanism, and it come down when vial hold by starwheel for filling operation and starts filling when it starts to move up and after completion of filling operation, starwheel delivers two vials together on conveyor for rubber stoppering operation.
Stoppering unit consist of Star wheel, Vibrator unit and Bowl. The sterilized and siliconized rubber stoppers stored in the vibrator bowl moves vertically to the rubber stopper chute. The vial is hold firmly by starwheel, which will be in continuous rotary motion and vial which is coming from filling unit get in to starwheel and move in rotary direction along with starwheel, during movement it picks up the rubber stopper from the exit end of the chute and rubber stopper pressed by fix single pressing roller, which is spring loaded. Then vial further move on conveyor and collected on out feed starwheel for next sealing operation.

A Vial Filling Machine is an automatic pharmaceutical machine designed to accurately fill sterile liquids (or powders in specialized models) into glass vials. It typically integrates vial feeding, precise filling, and rubber stoppering in a single monoblock unit. These machines are widely used for injectable products such as vaccines, antibiotics, and biologics under strict aseptic conditions.
The machine supports 2 ml to 250 ml fill volumes.
It is suitable for a wide range of round glass vials with quick-change parts for different formats.
The machine provides high filling accuracy of ±0.5% to ±1%. It uses precision piston pumps or peristaltic pumps with SS 316L syringes and non-return valves, ensuring consistent dosing and minimal variation even with different viscosities.
Yes. It is designed for aseptic processing with SS 316L product contact parts, compatibility with laminar airflow (Class 100), and features like “No Vial – No Filling” and minimal open-vial exposure time. Nitrogen flushing (pre & post filling) is available for oxygen-sensitive products.
Major features include:
These reduce wastage, prevent spillage, and enhance operator safety.
