Supor Syringe Filters

Supor membrane technology is a trusted name in laboratory and clinical filtration, valued for its low protein binding and high flow rates. This collection centers on the Supor Syringe Filter (H93824640), a device designed for the clarification and sterilization of aqueous solutions where sample recovery and consistency matter.

Supor filters use a hydrophilic polyethersulfone (PES) membrane, which is a common choice in life science and analytical workflows precisely because it minimizes the adsorption of proteins and other target molecules. For anyone filtering biological samples, buffers, or tissue culture media, that low binding characteristic means less loss of the very compounds you're trying to preserve and measure. The result is more reliable downstream data and less wasted sample.

Where these filters fit in the workflow

Syringe filters attach to the end of a standard syringe, letting you push a measured volume of liquid through the membrane by hand. Buyers reaching for a Supor unit are typically clearing particulates before HPLC injection, sterilizing small-volume solutions, or prepping samples for further analysis. Because the process is manual and single-use, contamination between samples is easy to avoid?an important consideration in any lab handling multiple prep steps in sequence.

When evaluating a syringe filter, the questions that matter most are membrane material, pore size, and housing diameter, since these determine what the filter will retain and how much volume it can handle before clogging. PES membranes like Supor's are well suited to aqueous and mildly organic solutions and are prized for fast flow that keeps prep moving without excessive plunger force.
