EM Equipment

Thermo Fisher Vitrobot Mark IV

The Vitrobot provides a cryo-fixation method by plunge-freezing into liquid nitrogen cooled liquid ethane. Proteins, viruses, nanoparticles, small bacteria and other samples in suspension can be vitrified into glass-like ice in a native frozen hydrated state. 

Leica EM PACT High Pressure Freezer

This High Pressure Freezer provides cryo-fixation method with liquid nitrogen to better preserve antigen for immuno-EM. Unlike chemical fixation resulting in sample shrinkage and extraction, high pressure freezing maintains natural structural integrity of cells and tissue sample.

Leica EM AFS Freezing Substitution

After high pressure freezing, this Freezing Substitution leads to resin embedded samples suitable without ice-crystal damage for both conventional and immuno-EM work at room temperature.

Leica EM UC6 Ultramicrotome

As a recent model from Leica, this provides semi-thin and ultra-thin section of resin sample block.

Reichert-Jung Ultracut E Ultramicrotome and FC 4E

This cryo-ultrmicrotome provides cryo-section for immuno-EM from cryo-protected sample block (Tokuyasu technique).

EMS 950 Turbo Evaporator

This evaporator allows carbon deposition on a bare grid to be more conductive.

EMS 850 Critical Point Dryer

This dryer provides critical point drying, which is an established method of dehydrating biological tissue prior to examination in the Scanning Electron Microscope (SEM).

Denton Vacuum Desk II Cold Sputter

This sputter allows either gold/palladium or carbon deposition on a variety of different substrate. This process is important for sample to be conductive in Scanning Electron Microscope (SEM).

Glass Knife Maker

This knife maker provides a glass knife for semi-thin and ultra-thin sectioning with ultramicrotome.

Fisher Heratherm Oven

This oven provides thermal polymerization (50-65°C) of a resin embedded sample. A function of countdown-type off timer makes the oven to shut down until it is scheduled.

Fisher ultra-violet (UV) lamp

UV lamp provides polymerization of EM sample embedded with acrylic resin (London Resin White or London Resin gold) at low temperature.
