Ready for a 5-qubit chip
Both packages use the ultra-compact LD: cryostat, gas handler, and rack in one frame, so the lab does not need a separate handler layout. An optional wiring kit for that qubit type is installed and tested before the system leaves, aimed at a five-qubit chip.
Four months, not a one-off build
Order to installation is four months for a tested system. Fixing the configuration also keeps the price under a refrigerator specified from a blank sheet.
LD350 with extra 4 K power
The pulse tube is a PT415-ENH with the tighter cold-head mount. Running the 4 K flange warmer can raise cooling power there by up to three times, without pulling the mixing chamber off its specification. The frame is quiet enough for noise-sensitive work. The vacuum can is in three sections for more room. A 4 K heater shortens the warm-up. Control is the generation-2 software.
Room to add wiring later
The refrigerator is the same LD family, so later coaxial, DC, and magnet options from the measurement catalog still fit.
