13 best syringe lab filters

• ✅VARIOUS APPLICATION - Needle Syringe filters are broadly used in life science laboratories for sterilization of small volume samples, such as protein, culture medium, additives, buffers, reagents, and drugs.
• ✅HIGH QUALITY FILTERS - Membrane Solutions sterile syringe filters with extremely high microbial filtration capacity and unique threaded interface design with ISO 9001 certificated.
• ✅PES MEMBRENA - Sterile Polyethersulfone (PES) needle filters have Polyethersulfone microporous membrane, belongs to hydrophilic membrane, high flow and lowest protein adsorption, which can meet the broadly applications, such as buffer, protein, culture medium, additives and so on.

User questions & answers

Question:	How many volume can this syringe filter
Answer:	The manufacturer says it's less than 100 ml. When I have used it, I seldom get past 60 ml without serious resistance. At that point I change filters. Note that I use a 60 ml syringe and push by hand.
Question:	How many times can you use one before having to open a new one? Aside from the I’m sure recommended one time
Answer:	It depends on what your filtering and how soon you filter. If you want to use the same filter for say clean water it can generally filter 30-40 mls, you’ll know when the filter is dirty and has reached capacity when it becomes difficult to gently push the fluid through. It would only use a stifle filter for larger volumes then my syringe within minutes to decrease contamination risks.
Question:	Can you attach a needle to it
Answer:	Yes the luer lock syringe needle tips slide over and attach to the tip of the filter and the syringe screws on the other side.
Question:	Does it matter what size of syringe you use
Answer:	Not for these 33 mm size. I use up to a 60 ml size with no problem. I was using the smaller 13 mm ones and found they stopped allowing fluid after about 10 ml. So if you have anything larger than about 10 ml, use the larger 33 ml size. These work with both luer loc and luer slip tip syringes. If you use a slip tip be careful not to apply too much pressure as the back pressure my cause the syringe to come off and your syringe contents to spew everywhere.

Membrane Solutions Lab Supply Sterile Syringe Filters PES

MS sterile syringe filters are made with a wide variety of membrane filters with polypropylene (PP) housing,using the most advanced methods and design features.

The most commonly types membrane for sterile syringe filters are PES and PES with GF pre-filter. PES features high flow and lowest protein adsorption, which can meet the broadly applications, such as buffer, protein, culture medium, additives and so on. And GF pre-filter has excellent dirt-holding capacity, which makes a syringe filter a much larger throughput for some “hard to filter” sample.

High Water Flow Rates

Polyethersulfone microporous membrane is a hydrophilic membrane with high flow rate, low dissolution, good strength, no adsorption of protein and extract, no pollution to samples.

High Bubble Points

MS filter withstands a maximum case pressure of 10 bar (145 psi) and the solution is 20% faster than comparable products

High Throughput

MS filter have a larger filter surface area increases the flow rate. It also reduces the pressure required to empty the syringe, making the filtration solution easier.

User questions & answers

Question:	Can these get wet and still work okay
Answer:	I have used these in 'airport lids' for grainspawn jars multiple times. Appears to go through the dishes suffering no ill effect. I know they say if a filter gets wet WHILE it is actively being used to filter air it's potentially a vector for contamination (ie mold/bacteria spores cross the filter barrier across the moisture gradient created). But getting them wet shouldn't harm them. I will say as well, PTFE is one of the only filter materials from what I see on Amazon that IS heat tolerant up to 251° (standard 15psi autoclave). Nylon and things like that are not.
Question:	What type of connection tip do these use? is it s luer-lock or a luer-slip
Answer:	There are two tabs on the larger side of the filter, I would guess they are locks. But I’m not a professional. Hope this helps.
Question:	For one of the items, why does it say Price:$35.99 ($3.60 / 10 Items) when the description says it comes with 100 of those items
Answer:	There are 100, $3.60 per 10pieces.

Throughout our entire syringe filters production process, we maintain only the strictest levels of quality control.

We use medical-grade virgin polypropylene housing and welded with a high-quality membrane, so you can be sure your filter will never leak sample solvent. For easy identification, we color-code our syringe filters and print specifications for membrane type and pore size right on the filter.



What membrane filter pore size should I use for sterilization?

Regardless of the membrane filter material, always use a 0.22 μm pore size membrane filter as the final filter for any sterilizing filtration.

How to choose Filter size

0-10ml Sample Volume use 13mm Syringe Filters;

10-100ml Sample Volume use 25mm Syringe Filters;

10-250ml Sample Volume use 33mm Syringe Filters.

User questions & answers

Question:	For sure is it sterile pes membrane filter individually packed
Answer:	Yes, each one I received is individually wrapped. The filter insure sterilization. This is why I pick this one but not biomed scientific syringe filter.
Question:	Do these work with luer lock syringes? How do I use them with a needle
Answer:	Hi you can’t use them with a needle, the inlet is female luer lock and the oulet is male luer slip. Have a great day Marc O’Shaughnessy Distribution Labsphere inc.
Question:	Can you recommend a pack that i could use with 31G and 30G both 5/16” needle and 29G with 1” needle
Answer:	Hello, I kindly recommend you use BD Ultra-Fine Insulin Syringes(ASIN: B07DM715D9) for 31G, 5/16'' needle and use Brandzig Ultra-Fine Insulin Syringes(ASIN: B084GD6DJH)for 29G, 1/2" needle. Please consider and check carefully before purchasing them. Thank you!
Question:	Can you lock a needle on the outside of these filters? So that you can push through the filter, needle and into a sealed vial all at once
Answer:	Hello, about your question, you need to draw the saline into the syringe, apply filter, fill a sterile vial, redraw the filtered saline with a second syringe. Filters lock onto a syringe that is designed for attachment. Before you buy it, pls check the order.
