ONiLAB Lab Micropipette, Single Channel Adjustable Pipettor, 200-1000ul

This product is highly accurate, reliable, and overall good quality for even at-home chemistry. I have confirmed that it does indeed deliver exactly the amount of reagent you select by using my ultra-precise scale. I have no worries about the effectiveness of this product.

Love my lab equipment- for my home lab! 🔬🩸

Works way better than I expected for the price. Would buy again.

I've been using the ONiLAB Lab Micropipette for a while now, and it's certainly durable – it's lasted a long time without breaking down. However, despite its longevity, I don't believe it's worth the investment due to some significant design flaws. My biggest issue is that liquid can easily get inside the pipette's mechanism, even when being extra careful. This makes it incredibly difficult to clean thoroughly. The prospect of disassembling it for a proper clean is also problematic; based on my experience with similar devices, doing so often compromises its future functionality, or worse, risks parts coming off entirely. For dispensing raw materials, I'd honestly recommend sticking with simple, inexpensive plastic or glass pipettes. While they might be single-use for each material, they eliminate the cross-contamination risk and the headache of trying to clean a complex, flawed instrument like this. The convenience and reliability of basic pipettes far outweigh the perceived benefits (and actual frustrations) of this micropipette.

I have been using this for reef aquarium water testing. It arrived mostly dialed in. I would recommend having a trusted method of verifying the amounts it is dispensing and, adjust it with the provided tool. It is easy to push the tip ejector while attempting to draw up a sample. This is easily avoided my rotating the pipettor so your thumb doesn’t touch it. However, while holding it that way, it is easy to accidentally spin the plunger while taking a sample, adjusting it to the next tenth. Also, depressing or releasing the plunger with any sort of haste will prove a deviation in sample size. So, take your time. These are minor issues and, it reliably provides repeatable sample volumes if you are attentive to its quirks. I feel like good value is provided for the price. It isn’t as effortless to use as the best ones out there but, it doesn’t cost as much as those, either.

I have ordered 5 of these! Love them so much that I ordered them as gifts for friends. I have the 2-10ml model and it is super accurate. No more drops when filling liquids from one large bottle to smaller 60ml bottles. Support from ONiLab is also top notch!

Solid micropipette to make repeated, and small, measurements much more accurate. This is a great middle ground between lab-grade and the constant use of a graduated cylinder or other measuring device. The precision is comparable to most using a beaker, grad. cyl, etc., but it is much faster, especially if using different volumes.

This is really bad cheap quality. I ordered one that I had to return because it broke the first day. I purchased a second one and same thing. They didn't even reimburse the full amount I paid. Also, I have extensive experience in lab so I know how to use a micropipette. The ones I received were both defective.

It has one job and it does it flawlessly.
