Helium-3 Insert with He4 Reservoir

The model ‘He3-SV4’ has a liquid helium reservoir built-in. This reservoir supplies the LHe-4 for the POT and for condensing He-3 gas. Ideal for applications where there is no access to the main LHe bath.

A liquid helium-4 reservoir is built-in! This insert has the standard He-3 pot, 1 K POT, and charcoal sorb and a He-4 reservoir that is filled externally using a vacuum insulated liquid helium transfer line.

A fill adapter automatically separates warm He-4 gas to allow refilling at any time without moving the transfer line position. This allows the transfer line to conveniently remain in place switched on or off as needed. (Note: If a transfer line is needed, ask about our LHe transfer lines with in-line flow valve.) The He-3 gas storage is also built-in - no gas handling needed.
