Vinotest - VST

- Integrity testable prefilter
- Repeatedly steamable in situ
- Sanitizable and regenerable
- Thermowelded construction
- EC-listed materials for food contact
- FDA-listed materials per CFR21

Vinotest membrane cartridges are designed for wine filtration as a testable prefilter in yeast and mould retention. The media is obtained by pleating a layer of PES
(Hydrophilic polyethersulfone) membrane with layer of Borosilicate Microfibers which acts as an incorporated prefilter.
The depth matrix of the Borosilicate layer retains both particular matter and deformable contaminants like colloids.
The cartridges are manufactured within a controlled environment; rigorous testing during the manufacturing processes guarantee high quality standards.
