What Are the Advantages of HAWACH Syringe Filters?

The syringe filter consists of a graduated syringe and a filter head, which the filter head contains filter membranes with different characteristics, and different performance membranes can be selected according to experimental needs. HAWACH syringe filter can meet the needs of liquid phase (aqueous and organic) and gas phase filtration and is used for bacteria removal, mycoplasma removal, cell culture medium clarification, carbon dioxide incubator aeration filtration, etc. in laboratory liquids.

Low protein binding: Specially optimized filter membrane material for biological samples, lower protein binding, low sample loss, low leaching, and wide chemical compatibility.

Larger filtration volume: Filter cartridge is specially folded and compact, increasing the filtration area and sample throughput.

Higher flow rate: Pre-filter layer design in the double-layer filter membrane increases the flow rate, saves filtration time, and prevents premature clogging of the filter membrane, extending the life of the cartridge.

Abundant products: Independent sterile packaging, no heat source, complete specifications and models to realize the whole process application from laboratory R&D, pilot test, to industrial production.

Pore size to cope with different filtration needs

0.2 micron: pore size filter membrane is used to remove
bacteria, fungi, and other microorganisms.

0.45 micron: pore size for particle removal and liquid
clarification, which can be used for viscous sample filtration, pre-filtration of complex particle samples, etc.

0.1 micron: pore size filter membrane for mycoplasma removal.

A variety of filter membrane materials for aqueous liquid, organic solvent, gas filtration

The membrane separation process is a method of separating mixtures using membranes. Microporous filtration is pressure-driven membrane separation technology. In HAWACH, there are different filter membranes to meet additional experimental requirements.

Hydrophilic polyethersulfone membranes (PES membranes) are optimized for liquid filtration needs in basic life science research, biopharmaceuticals, high flow rates, low protein binding, broad chemical compatibility, and higher recovery of trace samples.

Hydrophobic PTFE membranes with broad chemical compatibility, hydrophobic for a wide range of air filtration applications and for organic solvent filtration in analytical chemistry HPLC (0.45 µm) and UHPLC (0.2 µm) to prevent particle clogging of column packing and extend column life.

Hydrophilic PTFE membranes for aqueous, acidic, alkaline, and corrosive organic solution filtration, as a new generation of general-purpose membranes for all types of analytical QC experiments.

PVDF filter membrane has high mechanical strength, good tensile strength, good heat resistance and chemical stability, very low protein adsorption, and strong hydrophobicity. It’s mainly used in gas and steam filtration, high-temperature liquid filtration, tissue culture medium, additives, and other sterilization filtration, and solvent and chemical raw material purification filtration.

Nylon filter membranes are temperature resistant, chemically stable, and resistant to various organic and inorganic compounds and solvents such as dilute acids and bases. It is mainly used for the filtration of water in electronics, microelectronics, and semiconductor industries, as filtration of tissue culture media, pharmaceutical solutions, beverages, high-purity chemicals, water, and organic solutions in the mobile phase.

CN-CA filter membrane has uniform pore size, high porosity, no media shedding, thin texture, low resistance, fast filtration speed, and low cost. Still, it is not resistant to organic solutions and strong acids and bases. Common applications are Drinking water, surface water, well water, etc., sterilization filtration, analysis of particulate and oil insoluble matter in solution, water pollution index determination, gas, oil, beverage, wine, and other particulate and bacterial filtration. It is one of the most widely used filter membranes for sample pre-treatment filtration.
