precision process control
available in 32, 63 and 86mm chamber sizes
|optional quick-release specimen holder (down to 2µm in size)|
programme-and-save custom recipes
A fully automatic, digitally controlled critical point dryer with precision process control
The Autosamdri®-931 sets new standards for SEM critical point drying. Available in three chamber sizes it features intuitive touch screen control, allowing the user to enter preferred process recipes - or select from preinstalled factory defaults. Tousimis's Stasis software gives the operator complete range control - useful for more challenging specimens. There is a full range of specimen holders (see below), designed to meet most requirements. The process chamber is under-lit and has purge stirring to ensure complete fluid interchange.
Autosamdri®-931 critical point dryer highlights
- bright LCD touchscreen control
- choice of factory default settings or create custom "recipes"
- metering valves with vernier handles that include a slow fill for very delicate specimens
- internal 0.5µm particle filtration - protects specimens and valves
- rapid adiabatic chamber cooling (less than one minute for 31.76mm/1.25")
- internal condensing muffler - captures and eliminates purge exhaust noise
- top loading process chamber that is under light for easy viewing
- non-mechanical purge stirring for complete purge
- 'Stasis" processing (patent pending) gives complete range control for thicker specimens
- safe operation - fitted with rupture disk (activates @ 2000 psi) and pressure relief valve (activates @ 1250-1350 PSI)
- modern cabinet with clean room static-free design
