Acopelo Milk Sampling Tray, Milk Sampling Collection Tray, Mastitis Detection Board, Animal Husbandry Supplies-1 Pack

It does the job. The measuring lines are very useful.

Used for school & is a thick good piece of plastic. Not cheap

This is heavy duty, but does not have the correct lines to accurately measure both the milk and the testing solution to get equal amounts. There is one line that is equal to a 1/2 teaspoon. I added milk to that line and a half a teaspoon of diluted solution, that seemed to work. Though it was not convenient to have to measure out the solution separately.

Was exactly what I needed for CMT test

this doesn't have the inner circle markings that you need to the right measurement's/ratios for milk and chemical to get proper test results
