There has been an interesting focus lately on tools and work benches. I think it would be intriguing to have members show pictures of the weirdest or most unusual or most useless tools in their kit.
Do you have a convoluted screw driver or a set of misshapen pliers or a Smith chart slide rule or an abacus with a digital readout or a combination magnet/flashlight/scalpel? If so please share....
This is a peristaltic pump, it pumps liquid through a wave-like pressing of a tube action. The tube is plastic, flexible, and in this cased coiled in the round thingy. These pumps are used in science and medicine, when you need to keep the liquid away from mixing up with previous liquids (that could have been left in the internals of a traditional pump). This model supports different speeds and forward and backward direction.
