HCS402 Dual Heater Microscope Hot And Cold Stage
Instec's HCS402 microscope hot and cold stage features a dual heater design which virtually eliminates vertical temperature gradients in the sample chamber. This makes the HCS402 temperature controlled environment an ideal choice for thicker samples or when critical temperature uniformity is necessary. The stage can be used not only for microscopy but whenever an application requires optical access to a thermally controlled sample. All of the dual windows on the HCS402 stage are removable and exchangeable allowing the HCS402 to be used for small angle X-ray scattering, FTIR, and other experiments requiring beam access to the sample. The stage can also be mounted vertically for applications requiring horizontal beam access to the sample chamber. The interior of the HCS402 is large enough to accommodate a variety of samples, including electro-optic devices and cell culture preparations. Standard 25 mm x 75 mm microscope slides can be directly used as sample plates. An optional thermal shielding shell is also provided to optimize thermal performance for work requiring ultra-high temperature stability and uniformity.
