on flotty

[Gość: chemist]

Dear Jonatttan,
I am the lab worker and I received the method to analyse some chemical compounds.
One fragment of this method is unclear to me. It is: "Incubate at 40 C for 2
hours on flotty". Everything is clear to me except the expression "on flotty".
Can you help me with the explanation of it?
Thanks :)

The only "flotty" I have heard of is from South Africa:- a hat that
has a zippered pocket with a cork inside to enable it to float! I
would suggest you ask your lab supervisor for clarification.

It looks like a chemical slang expression from Latin or Italian "flottare" - English "float".
