This is a bunch of lab junk. The big knob is a handle for the Parafilm sealer. Parafilm is the coolest thing because its thick and super stretchy. It’s sort-of a cross between wax paper and Saran Wrap. With the sealer, you can make little packages.
The boxes behind it remind me of popsicle makers. Scientists put tubes of stuff, like drugs, viruses or liquid proteins in the boxes to freeze them.
