Syringe Filters Increase Sensitivity And Accuracy Of Analysis Results

Brief introduction

Syringe filters can be found in the chromatographic analysis to filter mobile phases and samples. The presence of impurities in the sample and solvent will not only cause damage to the chromatographic instrument and column, but will also greatly affect the analysis results. Organic phase syringe filters have a good effect on protecting the column and the chromatographic system from contamination, and can improve the sensitivity and accuracy of the analysis results. It is widely used in pharmaceutical analysis, food testing, environmental monitoring, protein removal and sterility testing.

Components

The shell is made of polypropylene (PP) with excellent chemical stability, made of different colors, which is convenient for users to distinguish between products with different specifications and avoid confusion. The filter membrane adopts high-performance filter membrane with stable product quality and good reproducibility, which is an ideal choice for laboratory filtration samples. The standard interface is convenient to connect with various syringes, and it can also be directly connected to the syringe of the valve, which can be directly injected after filtering.

Membrane materials determine the effectiveness of the filtration, and Hawach always implements high quality standard and humanized services, different syringe filters are available according to customer demand. The consistency between the production filter batches is good, from the raw materials to the production process and to the incoming and outgoing warehouse delivery management, the whole process has strict quality control, to the greatest extent to ensure the quality and use value of the product. Commonly membranes of various specifications such as PES、PTFE、Nylon、MCE、GF、PVDF、CA are provided, and the pore size range from 0.1μm to 5μm, the diameter includes 4 mm、13mm、17mm、25mm、30mm、47mm etc.

Syringe filters made of PTFE membrane has excellent chemical resistance, high temperature resistance, strong acid resistance, strong alkali resistance, strong hydrophobicity. Besides, hydrophilic membrane and hydrophobic membrane are all provided to meet different liquid filtration requirements. Polyvinylidene fluoride membrane is hydrophobic, which is featured in low moisture absorption, easy constant weight, and oxidation resistance. It is also design of thread interface.

Main features

The pore size is relatively uniform, the porosity is high, there is no medium shedding, the texture is thin, the resistance is small, the filtration speed is fast, the adsorption is very small, the price is low, but it is not resistant to organic solutions and strong acid and alkali solutions.

Uses: The pharmaceutical industry needs autoclaved water injection to filter out particles during large infusion.

For sterilization of heat-sensitive drugs (biochemical preparations such as insulin ATP and coenzyme A), use a 0.45 micron filter (or 0.2)

Medicine and health, using the thin film method to test the C-AmP, C-GmP and bloodworm of human body fluids, the determination of E. coli groups in drinking water, surface water and well water, and the detection of industrial and mining dust 0.8-5.0 microns.
