Descripton of Hydrophilic PTFE Syringe Filters

What is PTFE syringe? If the sample contains a lot of particles or viscous impurities, 0.45um syringe filter with a pre-filter membrane is your ideal choice. The pre-filtration membrane can remove particulate impurities while preventing sticky impurities from clogging the filter.

Just like the hydrophobic PTFE syringe filter, the hydrophilic PTFE filter also has a high flow rate, filtration accuracy as well as great resistance to chemicals and high temperature. Nevertheless, it possesses strong and permanent hydrophilicity without the need for pre-wetting. IC syringe filters are common to both aqueous and organic solvents.

Features

•Syringe filters for ion chromatography
•Excellent filtering and removing impurities
•High throughput for improved filtration efficiency
•Like CA syringe filters, hydrophilic PTFE syringe filter, High standard production environment and strict quality control.

Applications of Teflon syringe filters

•Venting applications
•Teflon syringe filter is compatible with: aggressive solvents, strong acids, alcohols, bases, aromatics

Hawach the filters stand up to the most aggressive solvent, acid, and base samples. Female Luer lock inlet, male slip outlet (50mm is hose barb). The product numbers ending with "B" are hydrophobic; all other PTFE filters are hydrophilic.
Syringe Filters for Ion Chromatography (IC) on Ion Extractable Test

The filter is the best choice for ion analysis and consistent results. Its high retention efficiency for fine particles can extend the life of the IC instrument. IC syringe filter with a very low ion interference low background value. Using ultrasonic welding technology, no leakage risk.

Note: Φ25mm filter because the filter area is larger than Φ13mm, the ion dissolution is also higher, so as the highest ion dissolution of the sample for testing.
2. Experimental Method
Teflon syringe filter is filtered 3ml ultra-pure water, the first 1ml discard, collect the first 2ml filter water and go on tested by IC Cl-, NO3-, SO42-. Each sample was repeated three times. Ultra-pure water directly tested by IC act as blank sample for comparison.

2. Disposable Hydrophilic PTFE Syringe Filters

Description of Disposable Non Sterile Hydrophilic PTFE Syringe Filters

The filters made from PTFE Hydrophilic membrane, which are used for many routine preparations in laboratories all over the world. PTFE syringe filters are convenient, disposables for filtration of liquids and removal of particles from solutions and gases. Different from sterile hydrophilic PTFE syringe filters, disposable hydrophilic PTFE syringe filters is a non sterile PTFE syringe filter and easy to use. Hawach PTFE-L syringe filters with pore size of 0.22μm are golden, and syringe filter with pore size of 0.45μm is pink.

Features of Nonsterile PTFE syringe filters

  • •Low residual rate
  • •Nonsterile PTFE syringe filters
  • •Disposable PTFE hydrophilic filters have two diameter(13mm,25mm)
  • •The color is easy to distinguish, gold color is 0.22μm and pink color is 0.45μm disposable PTFE syringe filter

Advantages of 0.22 um Hydrophilic PTFE Syringe Filters

  • •Luer lock inlet provides strong PTFE syringe connection to withstand filtration pressure at 6.2bar
  • •Medical grade PP housing with low extractable, no contaminant to samples
  • •Quantity break pricing for greater savings
