Pipette tip filter is made of ultra-high molecular weight polyethylene sintering forming, compact structure, strong and lightweight, can withstand the high filtration pressure, non-toxic tasteless, the acid and alkali solvent has good corrosion resistance, can prevent liquid aerosols and contaminant into the liquid inside, this will help reduce the risk of cross contamination, make the products more health and safety.
Catalogue:
Pipette Tip Filter 1.Material performance: PE with UHWM-PE as the main medium, with non-toxic odorless, no foreign body dissolution, physiological safety characteristics, in line with the requirements of GMP.
2.Chemical properties: PE filter medium has excellent corrosion resistance, resistance to all kinds of non-strong oxidizing acid, alkali resistance, aldehyde resistance, resistance to fat hydrocarbon, radiation resistance, etc., excellent chemical properties, resistance to organic solvents is also very good, under 80℃ can be resistant to ester ketone, ether and other organic solvents.
3.Temperature resistance: maximum 30min resistance to saturated steam temperature up to 130℃, long time continuous use of PE does not exceed 80℃.
4.Mechanical properties: good toughness and strength, impact resistance, installation and transportation is not easy to damage.
5.Filtration performance: the highest filtration accuracy up to 0.3 micron, high filtration efficiency, control the starting pressure can effectively remove 0.3 micron below the solid particles.
6.Physical properties: medium specific gravity is light, theoretical specific gravity is about 0.5-0.7g/ ml.
7.Regeneration performance: PE medium pores have the elasticity of microscopic expansion, can use water pressure, air pressure or water-pressure joint action for efficient reverse cleaning regeneration. It can use the appropriate concentration of acid to chemically dissolve the plugging material regeneration, so that the filter performance of the medium is restored as before, improve the service life of the medium.
8.Processing performance: can use turning, milling, planing, hot, hot fusion welding, bonding and other ways for secondary processing.
9.In summary, PE filter element aperture distribution is uniform, strong acid, strong alkali, high temperature resistance, good mechanical properties, has a strong resistance to organic solvent erosion ability. Production of large water treatment equipment, can use automatic or manual recoil slag removal method, solid particle recovery can use dry slag, do not need to change the filter element often, can be automated operation, low filtration cost advantages, well received by users.
With conventional pipette tips, the aerosol in the sample can contaminate the pipette and further contaminate the next sample, or cause potential harm to the operator. The function of the filter element is to block the aerosol from entering the pipette to prevent cross-contamination.
