The LNP95 cooling system designed by Linkam is a totally unique patented design. The precise control of liquid nitrogen flow enable specific stages controlled cooling rates as fast as 100C/min or as slow as 0.01C/min. The ultra efficient use of liquid nitrogen ensures that a day of cooling experiments can be achieved with just a 2L dewar.
The LNP95 has two proprietary pumps inside that are automatically controlled by the T95 controller A cooling system consists of the control unit housing the pumps and a 2 Litre dewar.
The novel use of the warmed recycled dry nitrogen gas is used to purge the sample chamber and clear the upper lid window surface of condensation. All tubes also remain perfectly flexible so that in polarized light applications the microscope table can still be rotated.
Note: Each dewar siphon is specifically calibrated for the particular stage it is to be used with.
Although all LNP95 pumps are the same, a THMS-LNP95 has a siphon calibrated for a different flow to an LTS-LNP95.
