Abstract

It is composed of a heating body ( 1 ), made from material resistant to corrosion and high temperatures, with a cylindrical top and a spherical cap for a bottom, around which, in its outer upper part, is placed a plated resistor, or heating blanket ( 2 ), the action whereof will cause the heating of the heating body, in whose inner space the flask which is to be heated is placed. Said heating body has an upper flange, by way of a circular hoop ( 3 ), which is fastened between two flat circular rings ( 4 - 5 ), made of a material with high thermal insulation capacity, an upper cover ( 6 ) being placed on these rings, the central circular orifice whereof is completely in line with the top of the heating body ( 1 ). An insulating screen ( 8 ) is placed therein which goes around the whole of the heating body ( 1 ), laterally and below, all the inner space of the apparatus being filled with wool or thermal insulating shavings ( 9 ). There is an electronic control module ( 11 ), acting from the exterior ( 11 a) of the chassis.

Description

technical field

[0001] The present invention relates to an electric heater, especially and exclusively designed to heat flasks or other similar containers customary in laboratories, as part of a specific method, in which the liquid product to be heated is pre-filled, the essential characteristics of the above-mentioned electric heater as described below. Background technique

[0002] As indicated in the preceding paragraph, it is particularly common that, for the purposes of research for the implementation of industrial processes, it is necessary to heat liquids, many of which are corrosive, which must be heated by placing them in suitable containers as known by heat-resistant material for safe disposal.

[0003] The heating of the flask and its contents is carried out in the usual manner with a customary electric heater comprising a hollow shell in which the flask is suitably placed, the shell being coiled around it according to the type of module The resistor on the outs...
