This advanced Ethane Cryostat Temperature Controller is designed to precisely regulate the temperature of liquid ethane within a compatible cryostat, ensuring highly reproducible vitrification of biological and material samples for cryo-electron microscopy (cryo-EM). It works synergistically with the Ethane Cryostat (SKU ML-TCCS-001-CD) to maintain optimal freezing conditions, preventing ethane solidification or premature evaporation. This controller is vital for achieving consistent, high-quality sample preparation, which is fundamental for obtaining high-resolution structural data. Power supply rates for input power 100-240VAC 50-60Hz. Supplied with a power cord, this unit integrates seamlessly into various laboratory setups. Its precise temperature regulation enhances experimental control and reliability, minimizing variables during critical plunge-freezing steps.
