  • ✅APPLICATIONS - SemmerFeld needle syringe filters are broadly used in life science laboratories,used for the sterile filtration of small samples, such as proteins, buffer solutions, media, additives, drugs and reagents.
  • ✅PRODUCT DESIGN FEATURES - SemmerFeld needle syringe filters feature a unique state-of-the-art design with a female luer lock inlet and male luer slip outlet. The shell is made of polypropylene (PP), and the interior uses a special three-layer design "upper layer - GF pre-filter, middle layer - PES filter membrane, and lower layer - PP diversion trench". This makes the needle syringe filters have a great capacity to absorb dirt.
  • ✅PES MATERIAL CHARACTERISTICS - The filter layer is polyether sulfone (PES) microporous membrane, with natural hydrophilic properties, good water wettability, asymmetry, so it has high flow, low precipitates, low protein adsorption and other characteristics, can meet the widely used in buffer, protein, medium, additives etc.
  • ✅INSPECTION & VERIFICATION - SemmerFeld needle syringe filters are pre-factory tested for pore size, flux, precipitation, and gamma radiation sterilization. This product is ISO90001 certified.
  • ✅MEMBRANE QUALITY - SemmerFeld PES membrane of this product has a uniform pore size structure and an efficient granulosa cell collection capability. With a diameter of 33mm and 0.22μm pore size, it guarantees the most efficient sterilization at high flow rates.

Listen, I've tried all the filters...ALL of them. This brand is the best in business. Some brands, you can feel a film or something on the inside and end up feeling like you need to wipe it out. That's not sterile imo. But this brand, no worries at all. Best filter on amazon. Yes, they're more expensive than the rest...but do yourself and your body a favor, spend the extra. Your veins will thank you later. I wish I knew about these years ago. Now my fixings are clear, dye free, and clean. Better late then never! Safety first ya'll!

Doesn't get much better than this. You can get down to 0.20 micron afaik. Should be standard procedure For illegal drug use. Unfortunately they are way too expensive for the regular addict, obviously spending the money on the drugs instead.

The Semmerfeld sterile syringe filters are great. I ordered the 100-pack which is a great deal. I grow all sorts of plants and mushrooms and mushroom substrate must be sterile or it will grow molds and it also requires gas exchange. I thought these would work grear for contaminant-free gas exchange and they work perfectly. I place the substrate in a mason jar and place the sterile syringe filter in the lid for gas exchange and it works perfectly, no contamination. Highly recommended.

These sterile syringe filters are the real deal. Each one is individually packaged so that there is no need to worry about contaminating the rest of the batch. These are hydrophilic, meaning that these filters let water through them. These filters do a good job of adding an extra layer of protection.
