Pipette - 2-20μl Micropipette, Adjustable Volume Pipette with Autoclavable Lower Portion, Universal Tip Cone Single Channel Pipettes, Laboratory ISO 8655 Calibrated Pipettor

Edit:I received what we determined to be a used, returned item. I ordered another 4E's pipette and it has since worked as designed. The company reached out regarding the first one I ordered and made it right. Great customer service.

This pipette provides excellent quality that doesn't break the bank. I do an awful lot of pipetting in my molecular biology lab. I have some hand/wrist issues and recently had to do a bunch of DNA isolations. I didn't experience any of the repetitive strain that can often happen. The plunger requires very little pressure to depress and the tips eject easily. I was able to use this pipette with tips from multiple different brands, so I don't think tip compatibility will be an issue. Overall, this is a great device and I would definitely recommend it to anyone just starting out or wanting to be more budget-conscious.

This micropipette has truly impressed me. In terms of functionality, it excels and has a beautiful design. Its volume measurements are flawlessly accurate and precisely in line with what it was designed to do. The suction power is just right. I enjoy using this micropipette and hope to eventually buy a full set that includes every size for my research lab. It exudes a strong sense of toughness, expecting the same on the long-term performance. I'll be sure to update this review if any problems come up as I use it more. In conclusion, I am really happy with this micropipette and would strongly suggest it to anyone looking for a dependable and affordable tool for their scientific activities.

As a chemist, I'm used to using Eppendorf calibrated micropipettes which cost several hundred dollars each. If they were replaced with these, I'd never know the difference. I wasn't able to test the calibration because I don't currently have a scale with enough accuracy (the best way to test is using distilled water and a good scale that can measure in 0.1mg increments), but it seems accurate based on my years of experience using these. My experience even with the expensive pipettes are they are 90% accurate at best for such small quantities.

Very good product

I usually don’t review products, but this is a really nice pipette! We needed an ISO certified and calibrated pipette with documentation for our laboratory and this was half the price of what we were quoted from our lab products distributors. At this price it is one of the nicest pipettes we have in the lab and we can autoclave the lower portion. We also needed some more pipette tips and the seller was very helpful in checking the tip compatibility. We will be ordering more of these because this one is always in use and affordable.
