Syringe Filter(PES 0.45+0.2 μm)

Product Introduction

Alioth syringe filter is disposable, commonly used for sample processing before chromatographic analysis and removal of particulate impurities in liquid or gases. It provides a very convenient way for filtering small volume samples, commonly found in volumes ranging from a few milliliters to several hundred milliliters. Because its filtration retention volume is very small, it can help customers reduce sample loss, and provide sterile and non sterile product categories, with strong flexibility in selection.


Product Properties
