The pretreatment group includes 1) Freeze drier, 2) Buchi Oven, 3) Vacuum pump, and 4) Working bench
Those equipment can be used to do the pretreatment of various materials including 2D materials, graphene, metals, metal oxides, polymers. They could allow you to 1) dry your samples under low temperature and high vacuum, 2) dry the samples (e.g., powder, film, substrate) with controlled temperature no more than 300 oC under vacuum or ambient conditions, 3) process various experiments.
