I use it for sampling my beer and wine through the airlock hole especially for my refractometer.

Yes good quality and price. The 1mL pipette is especially useful in benchmark tests and "double dilutions." DDs are when you need a very fine measurement of something and your scale is not that accurate. For example to make a 50ppm k-meta solution dissolve 1g of k-meta in 114 mL of distilled water (result about 5000ppm). Then use the pipette to draw 1mL of that solution and add it to 99mL of distilled water to get 50ppm. btw best to get a few pipettes so you don't have to rinse so much between samples.

I use this pipette for getting yeast samples to do a cell count with my microscope. It works very well and is easy to fill and dispense the proper amount of slurry.

I can't get the lids off of the brew buckets without cursing so I StarSan this guy and put it in the airlock hole to get my gravity sample. Much easier.
