Incredible what one can find on Ricardo.ch, a Swiss version of ebay! Four old but running Mini Shaker from the 70s made by the company Adolf Kühner AG were up for an auction. Since the seller lives close to us, a meeting was arranged. The former physics professor surprised us with a wide range of second-hand laboratory equipment, which he sells through his own company. He was very excited to hear about our foundation and was extremely generous with the price. Now the mini shakers will be processed by us for a laboratory in the developing country.
