Some of you already use Quantum Northwest sample changers (https://www.qnw.com/product/neutroniq-1×8/).They claim that they can control the temperature in the range -15 °C to +150 °C. Has anyone already used them down to -15°C? Do they really prevent condensation on windows?
at JCNS (MLZ) me and of course the actual staff uses them. To gain temperatures below 5˚C just align the water bath circulater to lower Temperatures (it helps the Peltierelement).
To avoid condensing there are 2 methods , permanently flushing (parallel to the quarz windows with nozzles) with dry air/gas (e.g.N2), or using a kind of hood above the magazine and fill it from the bottem with dry air.
At D22 they have a kind of Plexiglas box, which is fine for that , build in the magazine and then flushing with dry gas. This should help.
