The utility model relates to the technical field of chemical reagent experiments, in particular to a flask with an explosion-proof function, which comprises a safety plug, the bottom end of the safety plug vertically penetrates through an opening at the top end of a thin bottle neck, a ball bottle body is arranged at the bottom end of the thin bottle neck, and a pressure relief through pipe is arranged on the outer wall of one side of the ball bottle body. And a pressure relief valve obliquely penetrates through the interior of the pressure relief through pipe, one side of the outer portion of the ball bottle body is sleeved with a first protective net sleeve, and one side of the first protective net sleeve is connected with a second protective net sleeve in an adsorption mode. According to the improved flask and the safety plug, automatic pressure adjustment is achieved, a controllable pressure relief channel is formed, the sealing performance and the safety are balanced, the relative positions of the pressure relief valve and the pressure relief hole are changed, high-pressure gas can be conveniently diffused and discharged in a fan shape through the pressure relief hole, the impact force and danger of gas injection are reduced, meanwhile, the pressure relief valve has a reset mechanism, and the safety performance is improved. The first protective net sleeve and the second protective net sleeve can effectively intercept large glass fragments generated when the bottle body is broken, and the large glass fragments are prevented from splashing to hurt people.

Glass vessel (11, 11'), in particular evaporation flask, for a laboratory device (30), in particular a rotary evaporator, with a vessel body (12) made of glass, which defines a receiving space (17) for a medium to be heated, in particular a liquid, characterized by at least one heating resistance element (20) which is in thermally conductive contact with the vessel body (12) and has a connection (23) for supplying electrical energy, wherein the connection (23) comprises at least two sliding contact surfaces (25) which surround a neck (15) of the flask-shaped glass vessel (12).

A non-invasive system and method for simultaneous monitoring of substances in a cell culture medium is described. This measurement is not in direct contact with the culture medium, but may be performed through the permeable membrane via an orifice in the culture vessel wall or an orifice in the flow cell. The non-invasive monitoring system and method can provide accurate and pollution-minimized monitoring of critical process parameters, including dissolved O2, pH, and dissolved CO2. The progress can enhance the control and optimization of the cell culture process, so that the cell culture effect is expected to be improved.

The present invention relates to a device for the collection, pre-analytical treatment, transport and / or grinding of a solid sample, comprising a flask for receiving the solid sample, a pre-analytical medium comprised in the flask and a plurality of beads also comprised in the flask, each bead having a diameter equal to or greater than 5 mm and a density of at least 5.0 g.cm-3. The present invention also relates to the use of said device and to a method for extracting all or part of at least one eukaryotic or prokaryotic cell from a solid sample.

Sample bottle, comprising a bottle body (1) and a holding device (3) at the bottom (11) of the bottle body (1), wherein the retaining device (3) is designed as a liquid-tight cap attached to the bottom (11) of the bottle body (1), which has a closed shape and into which the bottom (11) of the bottle body (1) projects and which prevents liquid from entering the area between the cap and the bottle body (1), characterized by , that the mounting device (3) has an electronic tag (4) and that the cavity of the mounting device (3) is filled with adhesive or silicone.
