Weighing & Dispensing Isolator


High protection isolator for sterile closed products, weighing materials, packing and refrigerating in the inert gas environment inside the isolator.


Positive pressure swirl, through the efficient filter and sealing structure to ensure product safety.

Fully consistent with IS0-14644, hourly rate standard.

The delivery module implements the material buffering function, and the operation module realizes the operation function.

Solid and liquid waste ports carry solid waste through a continuous bag system and pass waste liquid through a closed container or clean the liquid.

Weighing & Dispensing Isolator

Technical Features

For sampling, weighing and packaging of those high toxicity, high activity drug.

The air chamber and PRT transfer device composed the material transfer system can achieve the safe transfer of samples.

The turbulence mode allows the maximum pollution control during low air speed and resulting in low energy consumption.

Low negative pressure ensures the maximum pollution control and also reduce operator's fatigue.

Low chamber pressure and low wind speed, combined with shock-proof weighing platform to provide stable and accurate sample weighing.

Cylindrical dust-type air filter can be replaced by handling gloves inside the chamber to avoid contamination hurt operator's body.

The system integrates the function of chamber integrity automatic detection.

The smooth inner and outer surfaces is easy to clean.

The lighting system is designed outside the isolator chamber and is easy to maintain. It is easy to do the thoroughly cleaning in the chamber.

Adopts the cleaning gun (CLP) and drainage system.

Optional PUSH-PUSH filter, allowing online filter replacement operation.
