Features and Benefits
This system has been developed for the specialized field of cryobiology where extremely accurate temperature control is required. The BCS196 cryostage has been at the forefront of cryobiology for over 15 years.
Liquid nitrogen is injected directly into the block by the LNP94/2 cooling pump automatically controlled by the TMS94 temperature programmer. Temperature feedback is provided by a 1/10 din class B pt100 platinum resistor to give <0.01s response time.
By precisely controlling the rates of cooling and heating, ice crystal morphology can be intimately controlled and investigated.
Recycled nitrogen gas is used to purge the stage of moisture and prevent condensation hence enable the capture of clear highly resolved images.
For ice crystal seeding, a cold spot has been provided on one of the cooling pipes allowing nucleated freezing to be initiated.
In order to get highly resolved images, it is important to use a condenser extension lens. See Optical Accessories for more information
For ultra fast cooling, we can modify the BCS196 cryostage with a special push rod and copper post. This enables the Y manipulator to transfer the sample from a copper post to the pre-cooled silver block. This will cool the sample at an approximate rate of 5000C/min and is even faster than submersing the sample in liquid nitrogen.
