Introduction

Product Information

Positive pressure sterilizing filters are widely applicable to sterilizing filtration of aqueous solutions in biological laboratories, and can be used with a peristaltic pump, syringe or other positive pressure device. JET BIOFIL's 50 mm sterilizing filter is suitable for removing microorganisms, particles, precipitates, and undissolved powders larger than 0.22 μm from aqueous solutions. This product has the stepped hose barb design that ensures stable connection between the filter and the hose.This product is made of 0.22 μm hydrophilic polyethersulfone (PES) membrane and can filter samples up to 8 L in volume. Its excellent filtration performance and reliable sterilization capability provide an efficient solution for the sterilizing filtration of liquids in biological laboratories.

Filter surface with coding marks, clearly distinguish inlet and outlet

It is designed with a filling bell avoiding liquid splashing and pollution; Stepped hose barb design that ensures stable connection between the filter and the hose

Features

* The filter membrane is made of 0.22 µm hydrophilic polyethersulfone for high throughput and excellent filtration performance

* The products have an effective filtration area of up to 19.9 cm², and can filter samples up to 3.8-8 L in volume

* Maximum operating temperature: 45ºC

* Maximum inlet pressure: 3.3 bars (50 psi) at 25ºC
* Typical water flow rate: 390 mL/min at 25ºC under 15 psi
* It is designed with a filling bell avoiding liquid splashing and pollution

* Stepped hose barb design that ensures stable connection between the filter and the hose

* Filter surface with coding marks, clearly distinguish inlet and outlet

* Sterilized by irradiation, SAL 10^-6, DNase/RNase-free, non-pyrogenic, non-cytotoxic

Special Tips
The test results show that the 50 mm sterilizing filters are suitable for most aqueous solutions, such as acetic acid (5%), aqueous buffer, cell media, Clorox^® bleaching agent (5% solution), sodium hydroxide (10%), sulfuric acid (20%). The unlisted reagents should be tested for applicability before use.
