Denton Desk V TSC Sputter Coater

Denton Vacuum Desk V_TSC sputter coater

The Desk V sputter coater is used to prepare samples for SEM analysis. This fully automated sputter coater is designed for high-resolution electron microscopy. It is equipped with metal sputtering (Platinum) and carbon evaporation capabilities, oil-free turbo molecular pump, film thickness monitor and tilting/rotating specimen table for uniform coating. The unit is supplied with argon gas.

Leica EM CPD300 Critical Point Dryer

Leica EM CPD300 critical point dryer

A critical point dryer is essential for preparing delicate biological specimens for SEM imaging. The Leica EM CPD300 is an advanced, fully automated unit capable of drying delicate materials for high-quality imaging. This unit uses liquid CO2(critical point 31.1 °C at 1072 psi) as a transitional medium.
