Abstract:
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 ex-tending opposite the wells side; and at least two heat regulating devices arranged one behind another in one direction for providing a temperature gradient in that direction across the tempering block and arranged at the contact side of the body in an area contact with the contact side; wherein the at least two heat regulating devices are operable at different temperatures in a first operation mode for providing the temperature gradient and are as well operable at same temperature in a second operation mode for providing uniform temperature in the block, and wherein the thermostated block comprises at least two heat regulating devices arranged one behind another in a direction transverse to the one direction for providing the temperature gradient.
