Double chamber weighing and dispensing isolator: a universal solution for weighing and dispensing raw material from unknown containers of any size with unidirectional flow.

Performing risky operations, such as handling, weighing and dispensing high potent raw materials, in pharmaceutical manufactory has become safer and safer thanks to the double chamber weighing and dispensing isolator.

The double chamber weighing and dispensing isolator allows raw material containers of various sizes up to medium volumes to be transferred safely into the weighing chamber.

In addition, the same containers do not need to be decontaminated but can be safely transferred outside the weighing chamber by means of a bag out liner
