The VorTemp 1550 is made with platforms that work for 15 and 50 mL conical tubes. This is made with an 8 x 50 mL or 18 x 15 mL capacity. This is made with many temperatures to make it useful for handling bacterial cultures and digestions while working with a uniform environment to keep it running. This may work in cold rooms in sub-ambient conditions. It can shake and incubate samples at the same time and may be adjusted with a digital control. This uses shaking racks for 15 and 50 mL conical tubes and can be adjusted in one of many speeds.
