  • VARIOUS APPLICATION -PES sterilized needle syringe filters made of polyethersulfone microfiber hot melt bonded to a membrane material, which are widely used in various fields of life sciences to decontaminate all kinds of small-volume biological liquids, such as proteins, culture media, additives, buffers, reagents or drugs
  • UNIFORM PORE SIZE - Sterile PES Syringe Filter with uniform pore size structure makes sure of granule cell collection. PES Syringe Filter Diameter: 33mm and 0.22um pore size which can fastly sterilize of buffers, culture media or other solutions.
  • PES MATERIAL - The PES material has good hydrophilicity and can be wetted quickly and completely, and the asymmetric microporous structure of the PES material gives it a high water flux. It has good dirt-holding capacity. It also has low protein adsorption and low dissolution properties: it is not easy to interact with blood and other biological products. In addition, PES materials have heat resistance and acid and alkali resistance.
  • 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.
  • INSPECTION & VERIFICATION - Chudeng needle syringe filters are pre-factory tested for pore size, flux, precipitation, and gamma radiation sterilization. It is ISO90001 certified.

I really like that these are wrapped individually so you KNOW they’re fresh.Fit easily on the syringe and filtered well as far as could tell. I’m glad for it, seeing as how many I got. Wouldn’t want to have a bunch of duds.

Occassionally I am challenge to match a stain. Some times it id for very small projects but I use it to get to larger projects too. We use this to measure accurately small amouts of dyes or stains to mix together to match a item we are repairing. Once the color is matched we can reproduce the color based on the measured ratios in a larger volume if the color is for a large piece. We clean these and reuse them a few times.

I used these to filter a solution of l-carnitine, water, and benzyl alcohol. After about 6mL or 3g of l-carnitine I have to fill up the 3mL syringe I'm using and shoot 3mL out the filter to get it unclogged. It just starts going so slow. That's happened with every brand of this type of 0.22 micron syringe that I've tried though, and I've tried a few. So it's not a big deal to me and these do what they're supposed to. They are fantastic filters.

These were individually wrapped for sterile usage and also comes in a cylindrical storage container. Each one is fairly wide, so better for filtering larger volumes.

Tried to put medicine through it, it absorbed the entire shot.

Seem to fit and function as intended though I don't have a particle size device to test accuracy or precision.

Filtered sample as expected. I should have gotten filters with less surface area, I didn't actually need 33mm, so lost more than was necessary but that was my fault not the product.

I use syringe filters regularly for work to purify protein and nanoparticle samples, where the filter pore size and material are very important. This product works just as well as any name-brand 0.2µm PES filter product that we get from our typical lab suppliers, securely screwing into the syringe. Back-pressure from the syringe is standard, and the filter itself is able to process as much material before fouling just as any of the other ones that I commonly use.
