NEW from AmScope, this microscope stage temperature control system ensures accurate, stable thermal control of live biological specimen observations. Ideal for checking semen motility, it is sized specifically for the user's stage warming needs and is adaptable to all brands of biological compound and stereo microscopes. The stage warming deck is made of high-tensile aluminum which maintains a precise, constant temperature of less than +/-.1° C between a set range of 20° C to 52° C. Pre-heating the stage takes 1 to 2 minutes resulting in reaching the constant temperature desired. This stage warmer is ideally suited to maintain stable specimen temperatures while examining or analyzing sperm motility and velocity or other live biological specimens under a microscope.
Compatible with microscopes such as the best-selling B120 and T120, newer microscopes like the B110C or B270C, and any microscopes with a standard-sized stage.
