FLASK SEALING SYSTEM AND MICROWAVE TREATMENT APPARATUS WITH SUCH A SEALING SYSTEM

摘要

A sealing system for sealing one or more flasks (10) with a longitudinal X-X' axis, open at a first end thereof (11) for introducing a sample and positioned inside a microwave application cavity (100) for heating the sample is described. The system of the invention comprises a cap (20) to be partially inserted in the flask along the X-X' axis so as to close the open end thereof and retaining means (30) for holding the cap in a flask sealing position, wherein the portion (22) of said cap which is inserted in the flask has a peripheral skirt (23) capable of sealingly engaging the inner wall (12) of the flask under an excess pressure created therein by heating the sample with microwaves.
