Title:
DEVICE FOR LIQUID HEAT TREATMENT
Document Type and Number:
WIPO Patent Application WO1999046048
Kind Code:
A3
Abstract:
The invention concerns a device for liquid heat treatment, in particular in a laboratory, whereby there is little liquid loss by evaporation and which has a simple structure and is relatively inexpensive. Such a device is obtained by inserting a displacing body in a container heated in its lower region, for example a reaction tube, from above, in the zone of a container cylindrical, prismatic or conical section, thereby generating a narrow void space which encloses the body, and said container section is enclosed by a cooling block provided with a corresponding passage. The displacing body forces the vapour rising at the liquid surface to enter said narrow void space, thereby bringing about efficient cooling by the cooling device and condensation on the container inner wall, the condensate on the container inner wall filling it.
