The new EcoStand tube holder is an environmentally responsible alternative to conventional petroleum-based plastics. In addition to being made from a biodegradable corn-based resin, the EcoStand also features a user-friendly design for both the 50 mL and 15 mL tube formats.
The Steriflip filter unit is designed to work with standard 50 mL centrifuge tubes, which eliminates sample transfer. To filter, just attach the unit to a 50 mL centrifuge tube containing your sample, flip it over, and apply the vacuum. When finished, the filtrate collects in the attached 50 mL centrifuge tube.
