Syringe Filters - Pall Corporation

Syringe Filters. Pall supplies a comprehensive family of syringe filters offering a full range of sizes, volumes, and flow rates. Sterile syringe filters are typically used in life science applications to sterilize solutions or for clarification. Non-sterile syringe filters are used across a range of filtration and sample preparation applications. They are widely used in analytical chemistry for sample preparation, protecting analytical equipment from particle contamination.

Syringe Filter Tips - Tisch Scientific Support

Fasten the filled syringe to the FLL inlet of the syringe filter with a twisting motion. With the outlet pointed upward, gradually apply pressure to the syringe plunger to initiate flow. Continue thumb pressure until all the air in the device is displaced with liquid. Once liquid starts to exit syringe fitter outlet, stop applying-pressure, point the device downward and away from user.

Bubble Point - an overview | ScienceDirect Topics

Bubble point is a function of pore size, filter medium wettability, surface tension and angle of contact. The filter membrane is wetted and a gradual increasing gas pressure is applied. The bubble starts forming from the largest pore first. The gas pressure at this time is the bubble point for the membrane.

Why there is air bubble when using syringe filter? How to

Sep 10, 2018 · The cause of the air bubble might be high pressure applied to the filter. If the pressure applied to the syringe is above the bubble point of the membrane and there is air in the syringe, air bubbles will be forced through the membrane in bulk flow compared to the normally low rate of diffusion. It might also occur at low pressure when using

What is Membrane Filter Bubble Point - Tisch Scientific Support

A Bubble Point of a membrane filter is the pressure at which air will pass through the filter when it is wetted. This pressure is related to the pore size of the membrane and so this pressure measurement can be used to determine both the pore size of the membrane and the integrity of the filter. Determining the Bubble Point of a Membrane Filter

Syringe Filters - Sigma-Aldrich

The bubble point test uses the inverse relationship between bubble point and pore size to determine the maximum pore size of a membrane. 0.45 μm membranes typically have a bubble point between 10 – 25 psi, whereas a 0.2 μm membranes have a bubble point between 40 – 50 psi.
