Descripton of Hydrophilic PTFE Syringe Filter
The filter medium of the hydrophilic PTFE syringe filter is made of hydrophilic polytetrafluoroethylene membrane, which has very good chemical compatibility. Modified to be hydrophilic so pre-wetting is not required prior to filtration.
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 of Hydrophilic PTFE Syringe Filter
•Excellent filtering and removing impurities
•Syringe filters for ion chromatography
•High throughput for improved filtration efficiency
•Like
CA syringe filters, hydrophilic PTFE syringe filter, High standard production environment and strict quality control.
Applications
•Venting applications
•The 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.
Analysis for Ion Chromatography
1. Sample
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
The 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.

Description of Disposable Hydrophilic PTFE Syringe Filter
The filters made from PTFE Hydrophilic membrane, which are used for many routine preparations in laboratories all over the world.
Disposable hydrophilic 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 filter with pore size of 0.22μm is golden, and syringe filter with pore size of 0.45μm is pink.
Features
- •Nonsterile PTFE syringe filter
- •Low residual rate
- •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 Disposable Hydrophilic PTFE Syringe Filter
- •Quantity break pricing for greater savings
- •Medical grade PP housing with low extractable, no contaminant to samples
- •Luer lock inlet provides strong PTFE syringe connection to withstand filtration pressure at 6.2bar
Applications
- •Cleaning of small volume samples for HPLC or GC application

Description of 0.22μm, 0.45μm Sterile Filter
Sterile filter is a kind of filter connected to the front end of the syringe. Ion chromatography, which is commonly used in environmental analysis, also requires that no inorganic pollutants be introduced in sample pretreatment.
The hydrophilic PTFE syringe filter 0.22μm, 0.45μm can instead of PES, N6,
PVDF syringe filter, is used for high temperature liquid filtration with excellent biological safety, chemical inertness, low adsorption and high temperature resistance. The pore diameter is 0.22μm/0.45μm, the flux is large, the strength is high, and the high temperature does not fall off. Each PTFE filters is individually packaged and suitable for high sterilization requirements.
Features
- •Sterile filter
- •0.22/0.45 um PTFE syringe filters
- •Excellent particle retention performance
- •Optimizing background levels in sensitive IC analyses
- •Broad chemical compatibility and flexibility in the lab
Applications
•Sterile hydrophilic PTFE syringe filters are widely used in the following:
•Incompatible with: HF, Perchloric acid, Methylene chloride (limited exposure), Dioxane, DMF, formic acid > 50%
