BasicPette Multi-Volume Adjustable Micro Pipette 200-1000ul (200,400,600,800,1000)

This item arrived via USPS a mere 13 days from my order date from China! The item is packaged well, and came with accuracy date. For this model, it is +/- 1.0%, and CV%<= 0.6 at 1000 uL, and +/- 1.2%, and CV%<= 0.7 at 600 uL. I tested it against a more expensive, well-known brand and it was within the accuracy expected!This model is for a variable volume of 200-1000 uL, has a two-stop mechanism, and ejects tips easily. You can only set it at 200, 400, 600, 800 or 1000 uL, not anything in between.For our purposes of a undergraduate/graduate laboratory doing basic research, this pipette is right on the money and works excellent! I would highly recommend this to others with similar labs. I plan to order more to replace our old, worn-out micro pipettes!

It's rare to find great customer service in a modern e-commerce experience...but Basic Lab Supplies showed me that it's still about good honest people who keep their promises. Pierre Blosse took a proactive and personal involvement in getting me what I needed, even after something went wrong. That's the measure of excellence - personal involvement by a real human being.On a zero-thru-ten scale, Pierre and Basic Lab Supplies deserve a twelve. I'm buying another pipettor in a few hours, and I think I'll opt for one of the slightly more expensive ones with a precise display... but one thing is sure: I'll be buying it from Basic Lab Supplies. I was made to feel important and appreciated, and that's worth a lot to me... to find a supplier i can trust.

This is a very good pipette, easy to adjust and works very smooth, I bought 2 of them and arrived so much earlier than expected, thanks! They are intended for laboratory usage and seems to be pretty accurate. At this price they are a real bargain. Really recommended.

It does not work for me, the button does not sink the same depth every time, and the tips do not seal well.

Good. But doesn’t measure correctly.

Excellent product for a high school Biology/Bio medicine class with a price that allows for a class set.

good as delivered

Doesn't work, won't suck anything up. Will try to contact company to obtain replacement or refund.
