Safematic CDS-020 compact dehydrator and critical point dryer
The unique (patented) Safematic CDS-020 is a fully automatic drying system that allows specimen dehydration and critical point drying in one compact benchtop instrument.
The CDS-020 is designed for processing biological samples for SEM and TEM. Other applications include drying aerogels, hydrogels and small MEMS devices.
Featuring a 60mm diameter x 44mm high vertical specimen chamber, with built-in stirring and viewing window, the CDS-020 save valuable operator time by running the specimen dehydration and drying process concurrently.
The CDS-020 comes with four specimen holders for bulk SEM samples and for 8mm. 12mm and 22m diameter coverslips. Custom holders can be offered on request.
The process chamber is side-lit and has magnetically coupled stirring to ensure complete fluid interchange.
Features:
- Fully automatic, integrated dehydrator and critical point dryer
- Automatic sample dehydration (concentration and time configurable)
- Container for water and two different types of media (ethanol only)
- Automatic critical point drying
- Operation via touch screen graphic display 5.7″.
- Integrated environmentally friendly cooling (no CO2 required during cooling)
- High-strength stainless steel sample pressure chamber ~ Ø60mm x 44mm
- Side sight glass – clear view of specimen chamber
- Magnetically coupled stirrer – ensures optimum fluid exchange
- Software and hardware safety concept with temperature and pressure shut-off
- Chamber lid with twist-lock and lock detection
- Over pressure bursting diaphragm
