Equipment inquiry

Not really sure if this was the right category to put it in but here I go. A friend of mine is moving and he has one of these kits/equipment for sale (see in photos) and where I need help is understanding/determining the price of what I’m looking at.

Is that piece of wood on the Buchner to keep the flies out?

You have a 3 liter Büchner funnel
Maybe a 5 liter rotary evaporator
A chiller

Price will be dictated by quality. You should prob list the brands.

Ah thanks for the reply . Honestly I’m not sure what is on top of that as this equipment been sitting there for almost a year now, I’ll try to get brand names and get back to you !
