Critical Point Dryer

Controlled Specimen Drying

Critical Point Drying

Critical point drying is an efficient method for drying delicate samples. It preserves the surface structure of a specimen which could otherwise be damaged due to surface tension when changing from the liquid to gaseous state.

The Leica EM CPD030 gently dries specimens of a biological nature such as pollen, tissue, plants, insects, etc. as well as industrial samples for MEMS (Micro Electro Mechanical Systems) applications.

Before drying, many biological samples are commonly prepared through fixation and dehydration. The Leica EM TP is an ideal instrument for such methods. It provides safe and automatic processing for follow-on critical point drying.

After drying, the SEM specimens are coated with a metal such as gold, platinum or palladium to make their surfaces electrically conductive. Leica offers a range of high quality coating systems such as the EM SCD005, EM SCD050, EM SCD500 and the EM MED020 best suited for these processes.
