Integrity Testing
Polyfil™ Junior filter cartridges are batch tested for integrity using the Bubble Point Test. Procedural details are available from Porvair.
Effective Filtration Area
Up to 0.15m2 (1.6ft2) per 136mm module (depending on pore rating).
Applications
Polyfil™ Junior cartridges provide absolute filtration where reproducibility and consistency of performance are critical. Suitable for the filtration of aqueous and organic liquids, Polyfil™ Junior cartridges can be used as prefilters or final filters in the following applications:
- Small-scale biopharmaceuticals
- Opthalmic solutions
- Electronics and semiconductors
- Small-scale fine chemicals
- Pilot-scale studies
- Inks and coatings
Clean Water Flow Rates
- Typical clean water flow rate:
A 136mm (5”) Polyfil™ Junior cartridge exhibits the flow-ΔP characteristics indicated below, for solutions with a viscosity of 1 centipoise.
