This is a cool piece of history that we wanted to make sure sticks around! This super rare piece was created in the late 40s early 50s in Herisau Switzerland. It is a Titration machine, and was used to determine the concentration of an identified analyte. Metrohm was founded in 1943 in Herisau by Bertold Suhner and Willi Studer. At the outset, it produced measuring instruments for high-frequency technology and telecommunications. High-precision measuring instruments as well as radio receivers were added to its portfolio later on. This teal color is an element they've had since their onset, and they still use that to this day. I've only ever found one other for sale, and sold it years ago. Make sure you pick this up quick if you cant live without it!
