Abstract

An incubation apparatus for microtiter plates includes an heating chamber and a incubation chamber. The heating chamber has a controllable hot air generator over which are arranged air guide devices for equalizing and distributing a stream of hot air to the microtiter plates. Air return devices are provided for collecting and returning hot air to the hot air generator. The heating chamber can be closed by a gate, and incubation chamber is divided by shelves into a plurality of compartments for receiving the microtiter plates. It is possible to close each compartment with a gate, and the side walls of the compartments are provided with heating devices. Furthermore, the incubation apparatus is provided with a gripping and transporting device having a working platform that is vertically displaceable and having a horizontally displaceable gripping arm.

Claims

1. An incubation apparatus for microtiter plates, comprising:

a heating chamber for holding a microtiter plate and including a controllable hot air generator, a gate for closing the heating chamber off from the outside environment, air guide means for equalizing and distributing a stream of hot air to a microtiter plate disposed in the heating chamber, and return means for collecting and returning hot air form the microtiter plate to the hot air generator;

an incubation chamber located adjacent the heating chamber and, divided into a plurality of compartments by shelves for receiving microtiter plates, each compartment including a gate for closing the compartment off from the outside environment;

a plurality of heaters, each heater being associated with one of said compartments; and

gripping and transporting means having at least a portion extending between the heating chamber and incubation chamber, having a vertically displaceable working platform and a horizontally displaceable gripping arm, the gripping and transporting means for moving a microtiter plate between the heating chamber and selected compartment of the incubation chamber.

2. An incubation device as set forth in claim 1, wherein the heating chamber and the incubation chamber form a module in which the plurality of gates are arranged one above the other and are moveable along lateral guides.

3. An incubation device as set forth in claim 2, wherein the module includes means for individually opening the gates, the opening means including a plurality of catches, each catch being connected to a gate, and a vertically and horizontally movable gripping arm for engaging the catches.

4. An incubation device as set forth in claim 2, wherein the module further includes a storage hopper and a feed device for the microtiter plates.

5. An incubation device as set forth in claim 1, wherein the heating chamber and the incubation chamber form a module in which the gates are arranged one above another and are movable along lateral guides, the module being provided with a storage hopper, a feed device for the microtiter plates, and means for individually opening and closing the gates, and wherein the gripping and transporting means has a vertical axis and is rotatable about the vertical axis.

6. An incubation apparatus as set forth in claim 1, wherein the heaters are located an side walls of the compartments.

7. An incubation apparatus for microtiter plates, the apparatus comprising:

a heating chamber for holding a microtiter plate and including a controllable hot air generator, means for closing the heating chamber off from the outside environment, air guide means for equalizing and distributing a stream of hot air to a microtiter plate, and air return means for collecting and returning air from the microtiter plate to the hot air generator;

an incubation chamber, located adjacent the heating chamber and, divided into a plurality of compartments by shelves for receiving microtiter plates, each compartment including means for closing the compartment off from the outside environment;

gripping and transporting means having at least a portion extending between the heating chamber and incubation chamber, for moving a microtiter plate between the heating chamber and a selected compartment of the incubation chamber; and

means for selectively opening and closing the heating chamber and the incubation chamber to expose the heating chamber and the incubation chamber to the outside environment.

8. An incubation apparatus as set forth in claim 7, further including a plurality of heaters, each heater being disposed within a compartment of the incubation chamber.

9. An incubation apparatus as set forth in claim 7, wherein the compartments of the incubation chamber are vertically arranged in relation to the heating chamber.

10. An incubation apparatus as set forth in claim 9, wherein the compartments are arranged above the heating chamber.

11. An incubation apparatus as set forth in claim 9, wherein the gripping and transporting means include a vertically displaceable working platform and a horizontally displaceable gripping arm.

12. An incubation apparatus as set forth in claim 7, wherein the opening and closing means is connected to the gripping and transporting means.
