Laboratory Syringe Filter FAQ Guide
Filson laboratory syringe filter has a variety of materials and sizes, which has wide capability to meet most of laboratory’s filtration requirements. It is mainly applied in three aspects:
- Chromatographic analysis samples: By capturing impurities in analysis sample, the sample solution can be purer. Our laboratory syringe filter is suitable for HPLC, LCMS, IC and so on. It does well in protecting the chromatography column from damage, and also making the analysis results more accurate.
- Chemicals Solvents: Filson laboratory syringe filter has good chemicals compatibility. It can keep operate well in aggressive environments like strong acid, strong alkali or alcohol. And its PH tolerance range is from 1 to 14. Therefore, our syringe filter can be used to filter chemicals solvents.
- Biological solutions: With low protein binding capacity, Filson laboratory syringe filter has enough ability in dealing with biological solutions like steroid, fat and blood, etc. It also widely used in cell culture reagents such as biological solutions, cell culture medium, supplements, serum, antibiotics and so on.
- Common micron ratings: 0.2μm, 0.45μm, 0.7μm, 1μm, 5μm, 10μm, etc.
- Common diameters: 4mm, 13mm, 25mm, 30mm, 33mm, 50mm, etc.
The aperture can be as low as 0.1 micron to remove more than 99.9% of bacteria in solutions; the maximum diameter of 50 mm is sufficient to handle 5 L sample volume with huge filtration area of 19.8cm³.
Excepting common types, Filson can customize laboratory syringe filters for any material or size.
- Low protein binding capacity
- Accurate and uniform aperture
- Huge flow rate up to 450ml/min
- High temperature resistance of 180℃
- No adhesives and additives are included
- Being compatible with aggressive chemicals
- Almost no adsorption amount and extractables
- Available for various customized materials and sizes
To ensure optimal filtering performance and accurate analysis or detection results, avoid contamination, do not reuse the laboratory syringe filters. The tiny particles not visible to naked eye can cause cross-contamination and affect your results.
To select the most appropriate laboratory syringe filter, you need to comprehensively consider the filtration membrane, impurity bulk, sample volume, connection mode and other factors.
- Filtration membrane: The characteristics of different materials of filtration membrane are also different. Choose the most compatible material with samples according to the pH, protein binding rate, hydrophilic nature and other features.
- Impurity bulk: The bulk size of impurities determines the choice of aperture. If filtering bacteria or microbes, a sterile 0.1 micron, 0.22 micron or 0.45 microns syringe filter is required. When filtering solutions contain larger particles, big aperture syringe filter for example 5 micron or 10 microns is suitable.
- Sample volume: The corresponding syringe filter diameter is selected according to sample volume. Less sample size, the smaller diameter of required syringe filter. When sample size is about 1 ml, a 4 mm filter is selected and when sample size reaches 1 L-5 L, a 50 mm filter should be used.
- Connection mode: There are two common connection ways: double luer lock and luer lock/luer slip. Double luer locks provide safer and stronger connections to be used for applications that require online filtering. Female luer lock and male luer slip provide sealing connections that can be widely used in different applications.
The laboratory syringe filter is made of both hydrophilic and hydrophobic materials.
- Hydrophilic: nylon, PTFE, CA, RC, glass fiber, PES, PVDF
- Hydrophobic: PP, PTFE
For the hydrophobic filtration membranes, using water or alcohol pre-wetting, they can be hydrophilic.
Here are three methods for sterilization for laboratory filter syringe filter and the most commonly used being the third autoclaved:
- Rinse in 75% ethanol solution.
- Ethylene oxide gas sterilization.
- 121℃ or 134℃ steam for 15-30 minutes.
As more and more impurities are captured on the syringe filter membrane, the pressure on filter increases and syringe plunger becomes difficult to push. When the pressure is too high, you need to replace laboratory syringe filter to ensure excellent filtration performance and avoid rupture of filtration membrane.
