3 Buchi Reveleris x2 flach HPLC machines for cannabis seperation. These units came out of working lab and are in good working order. 2- 1500g columns will be included in the auction. The uv lambs are 30-40% life left and all three machines have ELSD upgrade, but there is only one air pump with the systems. 2 units are working the 3rd could work but we used it for parts, needs a communication board and a pump seal. We have a bunch of random parts for the machines that will also go with the sale.
