RMC Cryo UltraMicrotome

 

 The Ultramicrotome facilitates preparation of ultrathin sections of biological and polymer material for EM examination. High quality glass knives for ultramicrotomy can easily be fabricated using the Leica Knifemaker in the facility.  Diamond knives are also available for experienced users. There is an cryo attachement available with the RMC ultramicrotome  which enables semi-thin and ultra-thin sectioning of biological specimens and materials samples at sub-zero temperatures.

Gatan Plasma Cleaner

 

 Plasma Cleaner enables the removal of impurities and contaminants from surfaces through the use of an energetic plasma created from gaseous species. Gases such as argon , oxygen and hydrogen in different recipes can be used. The plasma is created by using high frequency voltages (typically kHz to >MHz) to ionise the low pressure gas.

Gatan Carbon Evaporator

 

 Carbon Evaporator can be used for metal sputtering for SEM and TEM applications. It can be used in pulsed or ramped coating modes.

FEI Vitrobot System

 

 Vitrobot is an automated vitrifying equipment for plunge-freezing of aqueous (colloidal) suspensions with a humidity control of 0~100%. The sample can directly be placed on a TEM grid in a humidity and temperature controlled chamber and is then rapidly plunge frozen in liquid ethane preserving the ultrastructure as close as possible to the native state. These samples can then be viewed under the TEM in cryogenic conditions. Applications range from Cryo-EM sample preparation on protein, colloids, virus and bacteria.

Gatan Turbo Pumping Station

 

 This TEM holder module offers intelligent design solutions for cryo-TEM needs and is the perfect compliment to Gatan cryotransfer holders. The self-contain modular bench top pumping station consists of the base unit that contains the vacuum pumps, gauges and electronics and the TEM holder and/or specimen storage modules attached to a specialized vacuum port located on the top surface of the instrument.

Gatan Cryo Transfer Holders

 

We have set of specimen holders for various applications

  1. Single specimen holder
  2. Multi specimen holder for loading three samples at a time.
  3. Tomography holders with a tilt range of  ±  80°
  4. Cryo Transfer holder.

Sputter Coater

 Sputter  coating in SEM is a sputter deposition process to cover a specimen with a thin layer of conducting material, typically a metal, such as gold/paladium. A conductive coating is needed to prevent charging of a specimen with an electron beam in SEM image.
