LTS350 Heating and Freezing Stage
The LTS350 is an easy to use versatile heating/freezing stage, with simple microscope slide mounted sample loading. The stage is optimised for isothermal sample analysis applications where high speed heating and cooling are compromised by larger sample area with excellent thermal stability of less than 0.1C.
The stage consists of a large area temperature controlled element with a platinum resistor sensor embedded close to the surface for accurate temperature measurements. The sample is simply mounted on a standard microscope slide in direct contact with the polished heating element and can be manipulated 15mm in X and Y direction. The sample chamber is gas tight and has gas valves to control the environment inside whether it is inert gas or humidity.
A specially designed copper sample cover lid creates a uniform thermal environment for the sample without compromising the X,Y manipulation. This thermal cover can maintain a thermal sample stability of better than 0.01C.
To minimise the temperature gradient across the sample, the light aperture in the block is only 2.5mmØ
See Analysa range of systems for complete system package configurations.
This stage can be used with either the TMS94, CI94 or TP94 temperature controllers
In order to cool below ambient you will need the LTS-LNP94/2 or /1 cooling system
Also see Optical accessories to see which condenser extension lens you may need.
