Syringe Filter with 0.22um Pes for Lab Liquid Handing 25mm

    Syringe filters are a cost-effective way to improve the quality of HPLC analysis, improve consistency, extend column life and reduce maintenance. By removing particulates before the sample enters the column, Navigator syringe filters allow unimpeded flow. Without particulates to create obstructions, your column will work more efficiently and last longer.

Application:
     In addition to HPLC, syringe filters have a multitude of other applications. A syringe filter adds a few minutes and a minimal expense to your testing process, but you will see a big return on your investment. 
Small volume venting
HPLC sample preparation
Removal of protein precipitates
Routine QC analysis
Dissolution testing

About PES membrane filter

 Polethersufone (PES) membrane for aqueous soltionoprovides removal of fine paricles, bacteria, vruses, andfungi making it a versatile membrane for pplicationssuch as sample preparation, sterile fltrtion and infusiontherapy. PES is an iherently hydrophilic membrane thatwets out quickly and completely resulting in fast flrationwith superior flow rates and high throughputs. Thehydrophilic nature of PES means no added surfactantsare used to increase wettability. PES membrane is alsoextremely low protein binding minimizing the likelihoodof target analyte binding. Polyethersulfone membrane iscompatible with EtO, gamma irradiation, and autoclavemethods of sterilization.
The low protein binding nature of the polyethersulfone membrane makes it well suited for biological sample prepa-ration. Available in a variety of pore sizes, the membranecan be used for coarse particulate removal in prefiltrationapplications or as a fine final filter for clarification. An excellent choice for bead-based, multi-plexed assays,the PES membrane yields high microsphere recovery andreduces the incidence of false positives in serological assays.




How to choose a syringe filter

Diameter Sample volume <1ml , choose 4mm

Sample volume<10ml, choose 13mm

Sample volume<100ml, choose 25mm

Sample volume<200ml, choose 33mm

Pore size

HPLC Column partical size less than 3μm,choose 0.22μm

HPC Column partical size less than 5μm,choose 0.45μm

Media
Sampels with water choose Hydrophilic PTFE
Sampels without water choose Hydrophobic PTFE
Sampels hard to filter choose PTFE with prefilter 
None of them? Other membranes we have: Nylon, PVDF, PES, MCE, CA, RC, Glass Fiber
