5mL Adjustable Volume Pipette, Lab Single Channel Micropipette, 1-5mL High Precision Pipettor, Autoclavable 1000-5000μl

So far it seems to work good, it saves me a lot of time working with my epoxy and seems to measure right.

The media could not be loaded. I purchased this pipette to make aquarium parameter testing easier, aiming for both speed and precise 1ml and 5ml measurements. I was excited to try it, thinking it would be a perfect fit. However, either I'm misunderstanding how to use a lab pipette properly, or this one is quite inaccurate.Using my 5ml API test tubes, I discovered that I had to set the pipette to 3.65 to dispense 5ml accurately. I expected that 1.00 would correspond to 1ml and 5.00 to 5ml, so this was surprising. Am I mistaken, or is this just not calibrated correctly? To continue using it, I’ll need to figure out the correct setting for 1ml, but even then, it feels like I’m trying to make a broken tool work.(UPDATE) - The seller reached out to me to try to figure out the issue. They've offered instructions and guidance and ultimately have offered to replace the pipette once their stock is replenished. I have updated the rating from 2 to 4 stars based on their excellent customer service and will update it once more when I receive the replacement and can test it out.

Great pipette at a great price. Very accurate too. Makes doing Hanna alkalinity tests very repeatable. Comes with a few tips as well.

Acurate

2ml-10ml adjustable. Adjustment doesn't make sense though. Aside from not being able to dial down to 0...0 doesn't equal 0. And 10 doesn't equal 10. 7.5 somehow equals 10ish.If it was sensible adjustments and accurate, this would be great.

I was looking for some micropipettes for petri dish cell culturing. This 0.1-2.5uL pipette looks like it'll do the job. It has a little instruction booklet with information on usage and calibration. Calibration is very important when working with such tiny volumes, so it's good that this includes that.I have not checked nor confirmed the precision and accuracy of this pipette. I don't need both, but I do need repeatability, so high precision would be nice. Being able to recalibrate helps in that regard.

If you diligently test your aquarium parameters, having an accurate adjustable pipettor like this will make your testing life quicker and easier. This is particularly true if you are using Hanna Checkers and are testing multiple parameters.

Works well.
