Filtration is achieved by pushing the sample through the membrane. This can be done using membrane filters into a filtration unit, with a syringe or other luer-connection devices, using syringeless filter vials or microfiltration centrifuge filters.
Syringe filters allow you to control the rate of flow, which can be critical with delicate samples. Syringe filters also allow you to filter into nearly any tube, vial, cannula, or column that represents the next step in your analysis.
Syringeless filter vials provides rapid single step sample preparation and reduces sample loss. They are a ready to go solution for HPLC or UHPLC applications.
Microfiltration Spin Filters are very useful for small volume sample filtration. Designed for use in centrifuges, the filter units consist of a sample chamber and a receiver tube. This tube has a marking area and is graduated. A cap serves the dual purpose of capping the sample chamber during the centrifugation and the receiver tube after the sample chamber has been removed.
Each package is imprinted to identify the pore size and membrane type.
