My name's Nimaradee, i'm researcher from KMUTT. I used your DGGE system long time for research and study. I have 2 set of DGGE system, but one system it can not fix and other system leaks and send to repair. So my boss have an idea to bying only the Electrophoresis tank because we have accessories excess. When i contact your distirbutor (ITS company), sales agents said that they can not sell only the Electrophoresis tank.
