Im Handel erhältliche und geeignete Vakuumisolationspaneele haben z.B. folgende Eigenschaften: eine Wärmeleitfähigkeit um 0,004 W/(mK) bei 10° C; ein Kernmaterial aus einer mikroporösen Kieselsäure-Platte mit einer Dichte im Bereich von 160 bis 180 kg/m3; eine Umhüllung aus metallisierter, hoch vakuumdichter Kunststofffolie; Standard-Größe 1,0 x 0,5 m, andere Größen erhältlich; Stärke (Dicke): 10 mm bis 40 mm, typisch 20 mm; rechtwinklige Kantenausbildung, fast fugenloses Stoßen möglich. Bei solchen Vakuumisolationspaneelen ist z.B. ein Vlies zwischen Pulverkern und Kunststofffolie angeordnet. Solche Vakuumisolationspaneele sind beispielsweise bei der Firma va-Q-tec AG in D-97080 Würzburg erhältlich.
In dem Kältegerät sind vorteilhaft ein oder mehrere Böden (z.B. Lochböden) oder Fächer 15 angeordnet. Der Isolierbehälter 1 dient vorteilhaft als Quelle für kaltes Gas (wie in Fig. 10 gezeigt) oder zur Flüssigentnahme des Kühlmediums (z.B. Flüssigstickstoff), etwa über eine Steigleitung, insbesondere zum Versprühen des flüssigen Kühlmediums im Kühlraum 13 des Kältegerätes 12.
Die Isolierung 8 des Kältegerätes 12 ist vorteilhaft mit Vakuumisolationspaneelen aufgebaut, beziehungsweise enthält einen oder mehrere Isolationskörper, die wie ein Vakuumisolationspaneel aufgebaut sind.
