Patent Images
1. A thermostated block for laboratory thermostats, comprising:
- a body of thermally conductive material and having a wells side with a plurality of wells for receiving a plurality of sample liquid-containing vials provided between opposite end sides of the body, and a contact side extending opposite the wells side and parallel thereto; and
at least two heat regulating devices spaced from each other and operable at different temperatures for providing a temperature gradient in one direction across the thermostated block and arranged at the contact side of the body in an area contact with the contact side;
wherein at least one of the at least two heat regulating devices is opposed by at least two wells arranged one behind another in the direction of the temperature gradient.

Abstract
The invention concerns a thermostated block for laboratory thermostats and comprising wells at a wells side to receive and make large-area contact with the parts of vials filled with sample liquids and comprising at least two heat regulating devices contacting the thermostated block in thermally conducting manner to generate different temperatures at different sites of the thermostated block, said block being characterized in that the heat regulating devices are in large-area contact with adjoining zones of the contact side opposite the wells side of the thermostated block.
