Critical Point Drier

Autosamdri®-815B, Series A

Sample prep for biological samples is an integral part of achieving high-quality SEM images. Any sample can be placed in the chamber and imaged, but the quality of the sample prep determines the quality of the SEM micrograph. Critical point drying can be an essential step in the sample prep process for soft tissue and other samples. When a Critical Point Drier is needed, we suggest tousimis and their:

Autosamdri®-815B, Series A



Extra large chamber capable of drying very large or numerous smaller samples.

Excellent choice for active facility enhancing process CPD capability.

Chamber Inserts* reduces chamber ID to 3”, 2” or 1.25” I.D. maximizing LCO2 consumption efficiency and process time.

Vernier handles on all metering valves allow for reproducible settings.

Indicator control LED’s panel effectively indicate run status.

Internal filtration* protect samples and valves down to 0.5µm.

EZ top loading process chamber.

Under-lit chamber with viewing port aids visualization of chamber status.

Internal surfaces inert to LCO2 and ultra-pure alcohols.

Advanced solid state reliable electronics.

Microprocessor* controller for repeatable operating parameters insuring reproducibility of results via Automatic process.

Integrated temperature control.

Fast adiabatic chamber cooling* with CO2.

Static pressure control module for automatic pressure stability.

Tough, solvent resistant cabinet.

SOTER™ Condenser* is included with system to capture waste alcohol and deaden PURGE exhaust noise.
