1. Glass Fiber Syringe Filters

Description of Glass Fiber Syringe Filter

Luer lock syringe filter (Luer connector, or Luer-Lock connector) can hold the needle firmly and is an ideal accessory product for the syringe. Under normal circumstances, the liquid is filtered and distributed to small containers, and the pressurized small-volume liquid is passed through the filter. At this time, the pressure of the bolus injection is very large, even up to 3~4 bar (kg/cm2). For ordinary sliding-mouth syringes, the filter is likely to fly away, making the experiment impossible.

The polydiene shell of Luer lock syringe filter does not contain dyes, reducing sample contamination; and contains a complete glass fiber medium pre-filter, even difficult-to-handle samples can be easily filtered by hand. Hawach Filtstar glass fiber syringe filters act as a valuable pre-filter to extend membrane life with strong dirt absorption capacity.

Hawach innovative design and high quality products. Luer lock syringe filter have 0.45μm, 1.0μm, 1.6μm port size for choose. All have female luer lock inlet connector, male luer slip outlet connector. Maximum working pressure 5.2bar. Hawach has two sterilization methods: sterile and non-sterile. Hawach offers three kinds of pore size (0.45μm, 1.0μm, 1.6μm) GF syringe filters to meet most customer requirements. Among them, 0.45 micron glass fiber syringe filter is a natural hydrophobic filter medium, which has the characteristics of large flux and large dirt holding capacity.

0.45 micron syringe filters is a hot sale product and are always used in coarse filtration and pre-filtration, preferentially retaining large particles.It is suitable for the conventional filtration of organic solvents such as high particle content and strong alkaline viscosity. Glass fiber syringe filter is ideal for handling viscous and difficult-to-filter samples. Same as cellulose acetate syringe filter, Hawach syringe filter is most commonly used for liquid and gas dust removal, sterilization filtration, biological sample preparation, microbial culture medium, tissue culture medium, buffer solution, etc. in chemical HPLC-MS/GC-MS analysis.

Advantages of Glass Fiber Syringe Filter

2. Sterile Glass Fiber Syringe Filters

Hawach sterile GF syringe filters autoclave at 121°C at 1 bar for 20 minutes/EO/Gamma. Each syringe filter is individually packaged and suitable for high sterilization requirements. Glass fiber syringe filter in HPLC analysis, the particle size of the chromatographic column packing is small and it is easy to be blocked by impurity particles. Therefore, samples and solvents need to be filtered in advance to remove particulate contaminants and protect the instrument. Difference from sterile cellulose acetate syringe filters suitable for protein recovery, glass fiber syringe filter suit for HPLC analysis.

Advantages of Sterile Glass Fiber Syringe Filters

  • •Sterile Filters
  • •High flow rate
  • •Good mechanical strength
  • •Good pre-filter to extend membrane life

Applications of Sterile Glass Fiber Syringe Filters

  • •Syringe filter for cell culture
  • •Cell harvesting
  • •Fast pre-filtration of samples with high particle load
  • •Water and air pollution analysis
  • •Pre-filter of small volume liquids to avoid saturation of small-porosity membranes
