Critical Point Drying
Critical point drying is an effi cient 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 fi xation 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.
