Polyethersulfone Membrane Capsule Filters
|
|
|
| |
|
 |
|
|
mdi Polyethersulfone Capsule filters are self contained, ready to use, disposable
filtration devices that contain a mini cartridge filter element sealed inside a
polypropylene housing. The special design assures highest packing density of the
membrane per unit volume resulting in a very compact capsule offering long service
life.

- DPL: Single layered capsule filter for clear media, buffer filtration etc.
- DPS:
Serial filter, specially designed for filtration of difficult to filter solutions.
These incorporate a large pore size upstream membrane layer to protect the
downstream final filter.
|
| |
|
|
| |
- Absolute retention
- Low protein binding
- Very low hold up volume
- High flow rates
- 100% Integrity tested
- Total Traceability: Unique marking on each filter
|
|
| |
|
|
| |
- Sterile filtration of high value fluids like vaccine concentrates, hormones and
oncology drugs
- Scale up of new drug delivery systems
- Aseptic additions to fermentation processes
