Syringe filters are important consumables for sample pretreatment during high performance liquid chromatography (HPLC) and ion chromatography (IC) analysis in the laboratory. Low protein binding syringe filters can filter sample solutions, remove particulate contaminants, and protect instruments, ideal for routine use in laboratories to simplify process and improve efficiency. Sterile syringe filters can be used for solution sterilisation or clarifying sterile solutions, while disposable syringe filters are used for general filtration and sample purification.

Hawach Scientific Co., Ltd produce high-quality polypropylene membrane filters equipped with an ultrasonic welded shell that is clearly printed with pore size and membrane type information. Each filter undergoes rigorous testing in the laboratory to ISO9001, CE, COA and other certification standards.

Hawach syringe filters are available in these materials:

  • Nylon 66/Polyamide (NY)

  • Polytetraflroroethylene (PTFE)

  • Polyethersulfone (PES)

  • Celulose Acetate (CA)

  • Plyvinylidene Difluoride (PVDF)

  • Mixed Cellulose Esters (MCE)
