The K850 combines versatility and ease of operation. Built-in thermo-electric heating and adiabatic cooling allow precise temperature control. The K850WM is a compact, bench-top instrument with a convenient wafer holder allowing rapid transfer and ensures that pre-drying does not occur.

K850 

  • Side viewing chamber port : good visibility 
  • Built-in adiabatic cooling and thermoelectric heating : accurate temperature control, no external water supply needed 
  • Fine control needle valve pressure let-down : precise control of decompression avoids potential damage to specimens by uncontrolled pressure release 
  • Built-in magnetic stirrer : enhances solvent exchange 
  • Temperature monitoring and control with thermal cut-out protection 
  • Pressure monitoring with safety cut-out for over pressure 
  • Easy to operate valves : light finger pressure only is needed to open and close 
  • Optional holders for large specimens and coverslips 

The K850 is fitted with thermo-electronic heating and adiabatic cooling with temperature control of 5°C cooling and 35°C during heating. This allows pre-cooling of the chamber to aid filling with liquid CO2 and during the heating cycle ensures that the critical point is accurately obtained. Three valves: fluid inlet, flushing and a gas venting system which uses a fine needle valve to give controlled pressure let down. A built-in magnetic stirrer ensures thorough mixing of specimens with circulating fluids. The standard specimen holder has 12 individual chambers (8mm diameter x 8mm high) and allows easy exchange and transfer. There are optional holders for large specimens and for microscope coverslips. For very small specimens porous pots are available. 

K850WM 

  • 170mm diameter process chamber: optimised for wafer and MEMS drying 
  • Vertical chamber with top-loading and bottom draining: ensures specimens do not become uncovered during drying 
  • Thermo-electric heating: accurate temperature control 
  • Fine-control needle valve pressure let-down: precise control 
  • Temperature monitoring and control with thermal cut-out protection 
  • Pressure monitoring with safety cut-out for over pressure 

The K850WM has built-in heating and water cooling using the E4860 recirculating heater/chiller. This combination will give temperature control of down to 5°C cooling and 35°C during heating. This ensures the critical point is accurately obtained, avoiding excess pressures or temperatures, or the need to rely on pressure relief valves to control pressure during the heating cycle. The vertical chamber allows top-loading of specimens. A viewing port is fitted in the top plate for specimen observation. The exchange mechanism is simple to use and ensures specimens remain under liquid during loading. 

Specimen handling 

Single 4 inch or 6 inch wafers are held in a PTFE holding tray. The tray including wafer is immersed in chosen transition fluid (e.g. acetone) in order to remove all moisture from the specimen. After dehydration, the wafer and holder are transferred into the pre-cooled specimen chamber using the wafer transfer device. On completion of the critical point drying process, the wafer is removed from the chamber using the transfer device prior to further processing.
