Jet Biofil - ZEROTIP Sterile Universal Filter Pipette Tips - Micropipette - (Rack of 96, 200µl)

Great quality, works well.

Actually, I was really surprised when the pipette showed up in my recommendation list and I am researching scientist so I just ordered this and gave it a try. Since this is the brand that I have never seen in my entire career so I was relatively skeptical. BTW, most of us order these tips from the science material vendors like Fisher, it was very interesting to see this in Amazon. Further, it is a little more expensive than other conventional tips, so here is what I think.Build Quality and Design:Well, it does what it suppose do. I tested the volume accuracy and retention in my lab as you can see from the photos. It is fairly accurate and gives roughly the same volume as other well known brands like Oxford and Rainin. It has enough room below filter, so practically you can load more than 200 ul (not recommended of course.) The rack is stable and tips fits well with Ependorf, Accupet and Oxford. So in terms of design and build quality, it is very reliable.Functionality: It loads, retains and ejects solution very well, and as I mentioned previously, it fits well with most of the mainstream pipettes, also easily get removed by pipette removing button. There is no question on functionality. Yet, my question is that is it really worth to change your pipette tip brand? It's hard question to answer.Buy it if you want : to try out new pipette brandDon't if you need : better pipette to lower the budget in your lab. Practically, there are equally good pipettes (and probably better precision since this is 10ul to 200ul) with cheaper price available.P.S. The sterility was not tested.

These tips seem to be of fine quality. They include a physical filter within the tip. While this was fine for my Pipetman P200, it presented a problem for my Pipetman P20. The narrow bore of the P20 means that it fits farther into the pipet tip. The filter prevent the barrel from sliding far enough into the tip to keep the tip on the P20. Again, it works well on the P200. Since it is marketed as a tip that can be used from 10 to 200 microliters, I think it is important to note this limitation. It is not reasonable to expect a P200 to accurately measure small volumes, which means that one should not count on using these tips for that purpose.

Staying true to its description, this item delivers the intended performance without any difficulties.

Others have done a great job with the features. In case it's not obvious from other reviews, the lot I received expires in 14 months. Should be plenty of time for a regular user, but FYI in case you're a low(er) volume user that must use them before expiration.

I love this tool. Just remember it’s going to write exactly as you do. No better than you’re able to write and control this little scribe. 👍🏻

Although a bit pricey, these are high quality pipette tips. They work well, as advertised.

These are disposable pipette tips, presented in a color-coded rack. They are made of tough, non-absorbent polypropylene, sterilized by irradiation. This is a quality product.
