Syringe filters are available with the following membranes: Nylon, MCE, Polyethersulfone, Polypropylene, PTFE, PVDF & Regenerated cellulose. Porosities range from 0.1 µm - 10 µm, available filter diameters range from 4 mm (up to 2 ml sample volume) up to 30 mm (up to approx. 200 ml sample volume). Adapted with luer-lock in order to prevent filter blow-off. The membrane & porosity is imprinted on filter housing for certain identification.
Our stirrer bars are made from PTFE making them great for inert work. With dimensions from 2 mm up to 30 mm they are compatible with even the smallest containers. For perfect stirring cylindrical, oval, crossed shapes are available. Stirrer bars come in range of different colors.
