Description of Syringe Filter PVDF

Hawach disposable hydrophobic PVDF syringe filters are with the membrane made from the domestic quality supplier. Syringe filter with pore size of 0.22μm is black, and syringe filter with pore size of 0.45μm is red. It is widely used in biological, chemical, electronics, medical and other fields.
Syringe filter PVDF has the lowest protein adsorption among the syringe filters. Hydrophobic PVDF filter is ideal for filtering protein solutions. Disposable filter 0.22μm and 0.45μm pore size is no-sterile grade filter. Syringe filter membranes with larger pores are used for clarification and pre-filtration.

Polyvinylidene fluoride (PVDF) is suitable for chemically corrosive organic solvents, has hydrophilic characteristics, very low protein adsorption, and can filter out moisture in air and gas. The polyvinylidene fluoride membrane is laminated on the support net, which has strong strength and operability, and can withstand high temperatures.

Hawach syringe filter PVDF is a common method of choice for filtering small samples in HPLC and GC. Any product of Hawach is produced and tested under strictly controlled conditions to ensure products with multiple specifications to meet the different needs of users. For example, before performing instrumental analysis (such as HPLC), disposable PVDF filter 0.22 um can be used to routinely filter samples, which helps users improve experimental results, reduce unwanted peaks, and improve the signal-to-noise ratio and extend column life and other effects.
