Science Buddies: "Ask an Expert"

I’m planning to do this project from science buddies:

Is there was an alternative to using cuvettes as they won’t be shipped in time for my project due date in March?

Hello and welcome to Science Buddies,

It looks like Amazon is offering 2-day shipping for these cuvettes:

Does this help?

Yes. Thank you very much.
