Sterile Access Block Sanitary Diaphragm Valves

Features & Benefits:
Applications:
Single block valve with single or double sterile access valves for manual on/off or air actuated flow control for transfer, diversion or sample of drug process additives, WFI and other critical system fluids.
Upstream:
- Bioreactor/fermenter: for sampling or transfer of critical process fluids, inputs or WFI upstream of, and prior to opening the main valve.
Downstream:
- For sampling or transfer of critical process fluids, buffers or WFI upstream of and prior to, opening the main valve in the following areas: separation, filtration, chromatography, formulation, fill finish
Buffer and media prep:
- For sampling or transfer of critical process fluids, buffers or WFI upstream of, and prior to opening the main valve.
