Two-stage pulse tube cryocooler (RP-062B, RP-082B)
Brand: Lake Shore | Category: Nanotechnology
This two-stage pulse tube cryocooler reaches a base temperature below 3.0 K, which extends its range of use to low temperature, low vibration applications. Because the pulse tube cooler carries no internal moving parts, vibration levels are inherently low. Two models are published, the RP-062B rated at 0.5 W at 4.2 K and the RP-082B at 1.0 W at 4.2 K, and both are for vertical orientation only.
