In this video we build the main piece of a simple rotovap system. Rotovaps are a more advanced but also more specialized form of distillation where gentle heat, rotation and vacuum is used to remove solvents from things that are otherwise too delicate to heat beyond lukewarm. They're used in industry and in labs often and they're the idea tools for concentrating biological materials like chitosan or silk solutions which would burn or degrade if normal distillation was used.  Other times rotovaps are used for drying stubborn compounds like fluorescein which are notoriously hard to dry. 


The coupling we make is able to rotate freely, while maintaining the internal system under vacuum. It's made of a rod of solid teflon in a wooden support.

Ingenious. On the DIY theme, do you know of a heater control or dimmer that takes feedback from a thermocouple? Like within those expensive stirrer-heater units but external and detached?

Ya the one I used to build my incubator. Just look up inkbird on Amazon. All it is, is a control box, thermocouple, and socket. They're great

Could you do a video on somatic / protoplast fusion ? This procedure seems to be so advantageous in creating new crops but I hardly hear anything about it being applied in the real world. Maybe you could fuse a tomato and a very hot pepper to create a "Salsa Tomato" ? Being both from the night shade family, this might work out. What do you think ?

I've been collecting materials to try that at some point. I've got a bunch of other projects I need to get through first, but I promise it's on the list. Not sure what I'm gonna try and fuse yet though. But I do have the right media for plant cell culture and the enzyme for removing the cell wall, and PEG for fusing the things. I'm just not set up to actually grow plant cells atm.
