These PS vacuum filtration systems with premium PES filter membrane feature large quadratic filter surfaces which are 20% larger than with similar volume units with circular membranes.

• High flow rate
• Low protein binding, excellent chemical resistance
• Standard Luer lock connection enables a filtration at high pressure with a syringe
• Tapered form at the neck enables a firm and slip free grip, even with rubber gloves
• Quadratic form stores media more efficiently with less wasted space than circular bottles

Secure footprint: Flask with its sturdy square footprint is difficult to tip over during filtering and therefore eliminates the risk of encompassment of the filter unit by the vacuum tubing. Carefull handling of the highly breakable products is essential.

Triple bagged packaging for cleanroom applications:

The Triple Bagged (3-B) packaging system meets the strict cleanroom standards wich prevents that the contamination enters the highly sensitive area of production. Bags are security-opening style. The innermost bag 1 is labeled with the product details: product number, product description, lot number. Ideal for use in dedicated areas where the sterile transfer of product is essential. Each product is packaged individually in a tear-open bag. Each bag is labeled with a security number: 3 = external, 2 = moderate, 1 = innermost bag. The safety-open-style peel-open bags are increasing sized, so that during handling of one bag the next inner bag is not accidentally broken rendering it contaminated.

With the standard packaging, contamination adhering to the outside of the bag could be unintentionally carried into cleanroom areas. The 3-B packaging system prevents contamination from reaching highly sensitive production areas, thus significantly increasing safety for handling substances in a sterile environment.
