The cryopump can raise the temperature inside the chamber up to 330K or higher without heat loss during a pump regeneration process. As a result, substances and gases having large evaporation heat can be completely purified in high-temperature environments of at least 330K and discharged in a ...
range of demanding research and production applications. It can be used in any mounting position for industry-standard or custom designs. Silicon diode or hydrogen-vapor-bulb (HVB) sensors measure temperatures at second stage to help control the regeneration process (dual diodes are also available)...
The regeneration process can also be separated geometrically (e.g., in the case of three-stage pumps; cf. Fig. 5) by confining the heating to parts of the pump. Thus, very efficient fractionation of the different gases can be achieved by intelligent control of the regeneration process. ...
regeneration required. This mechanism is less susceptible to operational errors than other high vacuum pumps. If exposed to the chamber when the quantity of gas (Pressure x Volume) exceeds the manufacturer's recommended number, the pump simply warms, temporarily losing its ability to pump. After ...
- Boss HP and HP regeneration speed are increased, as well as the reward (number of the loot piles). - Decreased the boss damage multiplier to mechs x2 -> x1.75. - The boss jumping attack will add Dazed status effect (unless player is in a mech). ...
The sample freezing rate during the cryobioprinting process has a critical impact on ice-crystal formation and cell viability. Different freezing rates were achieved by changing the Tp. Given the dynamic nature of cryobioprinting, a constant freezing rate cannot be achieved throughout the construct....

Given the hardness of the bone, resin-embedding is the most common method of tissue processing18,19. While the resin produces a uniformly hard material for cutting and the technique produces tissue sections with very good cell morphology, the entire procedure is destructive. The process involves ...
This Cryo-Torr 8 Pump is a highly-reliable and rugged unit that requires a minimum of servicing. Since the cryopump exposes no moving parts, operating fluids, or backing pumps to the vacuum, the possibility of system or process contamination from the cryopump itself is eliminated. This is the...
is deactivated as soon as atmospheric pressure is reached. Optionally, after the sample is slammed against the cryo-slam surface 20 and removed from the cryo-slam surface 20, vacuum pump 59 is re-actuated to obtain a vacuum in the vacuum chamber 21 during regeneration of the cryo-slam ...
