Air thermostatic shaker, is a temperature-controlled thermostatic incubator and oscillator combined with biochemical instruments, mainly for large and medium-sized colleges and universities, medical, petrochemical, health epidemiological, environmental monitoring, and other scientific research departments for biology, biochemistry, cells, strains of bacteria and other kinds of liquid, solid compounds of the oscillating culture. Its main features: A: temperature control accurate digital display. B: the opening of the complementary oxygen hole, constant temperature working chamber oxygen sufficient. C: with mechanical timing. D: universal spring test flask rack is particularly suitable for a variety of comparative testing of biological samples for the preparation of the culture. E: stepless speed regulation, smooth operation, easy and safe operation. F: stainless steel cavity, corrosion resistance performance is good.
