A laboratory refrigerator, in particular a refrigerated incubator, in which an inner basin surrounding the useful storage volume is surrounded by an outer basin. The air in the useful storage volume is circulated via a chamber formed between the inner basin and the outer basin and re-enters the useful storage volume via apertures in the side walls of the inner basin. Heating elements are provided in the chamber for controlling the temperature of the circulating air and labyrinthine plate evaporators are provided on the outside of the side walls of the outer basin.

A removable shelf for a vacuum-drying cabinet is machanically expandable so that it comes into thermal contact under pressure over a large area with the heated walls of the cabinet interior. The shelf can be inserted into a supporting framework which can be freely positioned in the cabinet interior and can be removed for cleaning. A baffle plate on the supporting framework protects the material to be dried from strong air currents when the cabinet interior is evacuated.

A heating cabinet includes a fan (24) by means of which air is drawn out of the inner housing into an air chamber (22). From the air chamber (22) the air is directed through a preheating chamber (28) of U-shaped cross-section, comprising a heating element (34), enclosing the inner housing, and is directed back into the usable space through apertures (36) in the side walls (16) of the inner housing. Air guidance plates (38) are attached externally on the side walls (16) which compel the air to flow along the entire length of the heating element (34) before it can pass out through the apertures (36). In this manner, temperature differences between the air passing through the different apertures (36) are avoided and localized temperature variations in the usable space are minimized.

Heated cabinet

A shelf for laboratory cabinets, the cabinet having horizontal vertically spaced guides on the inner walls, the shelf comprising two parallel and vertically separated side bars, the lower of which cooperates with a lower guide on the side wall of the cabinet to support the shelf and the upper of which is spaced apart from the lower side bar by a distance substantially the same but not greater than the vertical spacing between adjacent horizontal guides.

A heating cabinet is formed of inner and outer side and bottom walls defining an antechamber between them which communicates only at the bottom wall portion with a rear air passage chamber formed between the inner and outer rear walls. A one-piece U-shaped heater of meander-like shape is contained in the antechamber spaced from the walls thereof.

A bellows type sealing member for sealing off a piston rod opening formed at one end of an operating cylinder for accommodating reciprocal movement of a piston rod therein, in particular a diaphragm type cylinder for vehicle air-brake systems, wherein the piston rod has one end connected to a diaphragm disk and is provided at the other end with a forkhead, and the bellows can be sealingly fitted on a sleeve-like support member mounted coaxially in the piston rod opening of the diaphragm cylinder.
