For over 50 years, MilliporeSigma has supplied wineries around the world with microbial management solutions to monitor and remove microorganisms and other contaminants from wine. Trusted as the “gold standard” by generations of winemakers, MilliporeSigma products for clarification, pre-sterile, and sterile filtration will ensure microbial stability while maintaining quality, clarity, flavor, and aroma.
The Vitipore II & Vitipore II Plus PVDF final membrane offers:
Lowest protein and color binding
Highest membrane area and number of pleats per device
Only major symmetric wine membrane
Higher membrane robustness and stress tolerance
Most reliable integrity testing
Available in 0.22 µm, 0.45 µm, 0.65 µm and 1.0 µm (absolute) pore size.
MilliporeSigma’s dual-layer 1.2 µm over 0.5 µm Bevigard M prefilter offers the best protection of sterile membrane filters. The outer 1.2 µm layer removes large particulates, colloidal materials and conglomerates while the 0.5 µm layer offers the closest prefiltration rating to a 0.45 µm membrane to ensure optimal bottle filtration service life.
Polygard® CR & Polygard® CE Clarification Filters
Polygard CR clarification filters are an ideal bottling filter when sterile filtration is not required. The high dirt loading capacity of the Polygard CR makes it a reliable trap filter for stable wines that require a minimal filtration prior to bottling. The Polygard CR is available in many other options and sizes, with pore size ratings from 0.1µm to 100µm.
Aervent® Gas and Vent Filters
Sterile filtration of gases can be crucial to maintaining microbial stability on a bottling line. The Aervent features a highly hydrophobic (water repelling) PTFE 0.2 µm membrane that allows for high gas flow rates, prevents wetting, and maintains a sterile barrier.
