Top Rated Syringe Filters – Ratings & Comparison in 2017
Nowadays, syringe filters have many uses particularly in science, although they may prove their worth in various other areas, as well. Because we know that the market is simply overflowing with models and it can be hard to find the exact product you are looking for, we’ve thought of creating a web page that hopefully assists you in making the right call. The website is packed with information regarding such types of lab equipment and will give you some broad pointers as to what is a syringe filter, as well as different tips and tricks regarding syringe filter compatibility.
There are several kinds of products available out there, and any prospective buyer can end up feeling a tad baffled, particularly if he or she is not a well-seasoned user of syringe filters. One of the first things you ought to know about these units is that they need to be attached to the end of a syringe of which the volume can vary from one model to the next. The fact of the matter is that, in this case, the capabilities of the filter are more important than the type of syringe you will be using, as there are various units that have different sizes and can restrict or allow the passing of smaller or larger particles.
Why are filters used? The liquid needs to be purified depending on the activity you’re trying to undertake. Some filters are so good at doing what they’re supposed to that they are able of blocking microorganisms such as bacteria and even viruses, but all this varies upon their dimension. While there are several kinds of filters to choose from, the vast majority is shaped like a wheel, with a difference. Luer lock syringe filters somewhat resemble a needle instead of a wheel, but the shape is often times a matter of personal preferences as all filters have a small-sized orifice which is used for letting the liquid out of the syringe.
Are you looking for the best syringe filter? If that is the case, you are in the right place. During our research, we have failed to find a comprehensive buying guide that clearly explains to prospective buyers what they should look for when analyzing the market for such a product. That is why we have decided to create a guide of our own which can hopefully shed light on some of the typical dilemmas one might have when shopping for the best syringe filter for steroids or any other type of sample. You’ll find all there’s to know about the topic below.
Syringe filter membrane selection
One of the first factors to ponder on is the material that the filter is made out of. Depending on this crucial consideration, these products can have different uses. From what we have gathered while reading about these products, filters can be constructed of cellulose acetate, glass fiber, nitrocellulose, nylon, polypropylene, polyethersulfone, PTFE, and PVDF. In spite of the fact that many of these units offer the best results when employed in environmental, food and beverage, pharmaceutical, and agricultural applications, there are several purposes that are more specific than these broad industries. For instance, a model made of nylon is probably the best syringe filter for aqueous solution, given that it is specifically designed to be used for the clarification and sterilization of such samples. As such, the actual professional use matters even more than the characteristics of the product, as it is the primary detail to take into account.
As previously mentioned, you ought to ask yourself just what you’re trying to achieve with the help of a syringe filter before deciding to choose one model over the next. PVDF units have high flow rates as well as low protein binding, for instance. PTFE syringes and vent filters can be constructed either with or without a prefilter built out of glass. Speaking of which, glass options prove their worth particularly when used as prefilters as they can prolong the life of a membrane especially when working with a sample that is viscous. If maximum sample recovery is what’s on your mind, you ought to choose an item made either of cellulose acetate or polyethersulfone. Blood analysis, whether we’re discussing red blood cell filtration, deformability, or plasmapheresis, usually requires the use of a PCTE or PETE syringe filter.
As for microorganism analysis, the matter is considerably more complex as each and every germ needs a different kind of filter with a unique dimension. For studying Giardia lamblia or Dirofilaria immitis you’d need a model made of PCTE with a size of 5.0 µm, but you’d need an MCE syringe filter with a size between 0.45 and 0.7 µm if you were to study coliforms found in fecal matters. It goes without saying that what makes the difference, in this case, is the nature of the pathogen, as the first are parasites, and the second are bacteria. Therefore, they have different sizes and require different filter sizes, as well.
Syringe filter. How to use
Just in case you haven’t tried using such a product before, we thought we’d include some simple details with regard to how you can make the most out of your sample. For one, you have to consider the viscosity and nature of the fluid, its volume, its chemical compatibility and whether it might work better with a certain pore size or with another. Once you’ve established all of this, you can proceed to use the right syringe with the right filter by simply uniting them once the needle has been removed. Continue by removing the substance in a recipient of your choice, whether it is a Petri dish or any other container you may need to perform your task.
Top syringe filter reviews in 2017
To make sure that you’re able to pick the right product for what you have in mind, we have created a concise selection of some of the top recommended units in the line. All of these filtration devices have been highly spoken of by the people who have bought them, as they manage to serve them well and perform as needed under most circumstances.
This Whatman option consists of a pack of fifty 25mm 0.2 microns sterile syringe filter, but larger sizes can be chosen as well, given the fact that we have found a pore size of 0.45 microns available.
While the housing of this model is made of polypropylene and is capable of accommodating the features of loaded samples over 10 milliliters, the membrane of this type of filter has been constructed out of PVDF.
This last piece of info basically means that the Whatman 6900-2502 can prove its worth both with organic-based and aqueous samples thanks to its low protein-binding properties.
The membrane appears to have more than adequate chemical resistance as it can be used with a wide array of HPLC solvents. It’s worth noting that the manufacturing company has been in the industry for many years now and is one of the most reputed UK-based brands out there.

As is the case with the product we have showcased earlier on, the Whatman 67802502 is a pack of fifty sterile syringe filters.
However, there are several differences between the 6900-2502 and this option, given the fact that these filters are made of fiber glass. Besides, the membrane has been constructed out of polyethersulfone, and the pore size of this alternative is 0.2 microns.
Another factor that makes the difference between this unit and others in the line consists of the fact that the 67802502 can accommodate sample volumes up to 100 milliliters. As previously discussed in the buying guide and given that this type of filter is made of polyethersulfone, it is probably the best bet if maximum sample recovery is what you’re trying to achieve.
