Needle tube filter membrane filter

In addition to its application in HPLC, needle filters have many other applications A needle filter may take a few more minutes and cost a little money during your testing process, but you will find that your investment will have a substantial return
Ventilation of the sample
Preparation of HPLC samples
Remove protein particles
Conventional QC analysis
Decomposition testing
Production environment
The product is produced in a 100000 level purification workshop (the purification room has been tested by a national professional organization)
2. Performance characteristics of filter membrane material in syringe

A. PTFE (polytetrafluoroethylene)
Performance: Suitable for water systems and various organic solvents, resistant to all solvents, low solubility. It has the characteristics of breathability, impermeability, high air flux, high particle retention rate, good temperature resistance, resistance to strong acids, alkalis, organic solvents and oxidants, aging resistance, non stick, non combustible, non-toxic, and biocompatibility. Its related products are widely used in fields such as chemical, pharmaceutical, environmental protection, electronics, food, energy, etc.

B. PES (Polyether Sulfone) water system
Performance: This product is an imported membrane from German company MEMBRANA, which has high chemical and thermal stability, fast flow rate, and strong acid and alkali resistance (pH range 1-14); Has high mechanical strength.

C. Organic Nylon 6 (Domestic)
Performance: Has good hydrophilicity, acid and alkali resistance, antioxidant. Not only suitable for aqueous solutions containing acidity or alkalinity, but also for organic solvents such as alcohols, hydrocarbons, lipids, phenols, ketones, etc.

D. Organic Nylon 66 (imported from the UK)
Performance: superior to domestic nylon 6 performance, this product is suitable for the vast majority of organic solvents and aqueous solutions, and can be used for strong acids, 70% ethanol, dichloromethane and other organic solvents. High temperature resistance, good strength, and stable chemical properties.

E. Polyvinylidene fluoride PVDF
Performance: Polyvinylidene fluoride film has chemical stability and inertness, and is suitable for sample preparation in highly corrosive organic solvents, strong acid and strong alkali solutions, and high-performance liquid chromatography analysis It has hydrophobic properties and can filter out moisture from air and gas Polyvinylidene fluoride film is laminated on the support mesh, which has strong strength and operability, and can withstand high temperatures of 130 degrees
