Hanna Cuvettes New Plastic also p04 testing

[CoralNerd]

Does anyone have any advice regarding how to remove the plastic inserts that now come inside of the hanna cuvettes?

FYI stupid new caps leak too.
One last thing I broke my first cuvette and started using one new cuvette and one old. Well found out testing p04 it's best to replace both cuvettes. Now to get off this plastic thing. Why do they even put it on yeesh.

Good question, I bought the box of 25 for maple syrup as replacements and they have the plastic insert. Took a couple of tools to pry that plastic out of there!

I pulled the plastic out by hand. It is there to keep inside glass clean. Use old caps or Hanna sells them separate

I only use one during testing so I don’t have to worry about glass effecting test results

Get an old ball air pump, insert needle and start pumping.
