Embodiment Construction

[0021] In order to clearly illustrate the technical features of the solution, the solution will be described below through specific implementation modes.

[0022] Such as Figure 1-3 As shown, the present invention is a saponification reflux nitrogen protection device, the upper end of which is connected to a reflux condenser, and the lower end is connected to a round-bottomed flask or a flat-bottomed flask. The upper connecting section 2 of the reflux condensing pipe is provided with a standard inner frosted port for connecting the reflux condensing pipe of the standard port. The lower end of the tube body 1 is provided with a lower connection section 3 for connecting a round bottom flask or a flat bottom flask. The end is set to beveled.

[0023] The side wall of the pipe body 1 is provided with a vent pipe 4, and the vent pipe 4 enters the inner cavity of the pipe body 1 through the side wall of the pipe body 1 from the outside of the pipe body 1, and the part of the vent...

Abstract

The invention discloses a saponification reflux nitrogen filling protection device. The device comprises a tube body, the upper end of the tube body is provided with an upper connecting section for being connected with a reflux condenser, a lower connecting section for being connected with a round bottom flask or a flat bottom flask is arranged at the lower end, the side wall of the tube body is provided with a vent pipe, and the vent pipe is inserted from the outside of the tube body through the side wall of the tube body into an inner cavity of the tube body; the vent pipe is bent downward in the front portion of the front cavity of the tube body, the bent portion the vent pipe is provided with arc transition, and the axis of the bent front section of the vent pipe is parallel to the axis of the tube body. The device has the advantages that the structure is simple, the design is reasonable, the device can be directly connected between the round bottom flask or the flat bottom flask and a condensing reflux tube, nitrogen can be conveniently charged into the round bottom flask or the flat bottom flask, the protection function is used for reducing the loss of the target substance, and the accuracy of the detection result is improved.

Description

technical field [0001] The invention relates to a medical testing equipment, in particular to a nitrogen filling protection device for saponification reflux. Background technique [0002] When the national standard method is used for the detection of vitamin E, saponification reflux is required for extraction, and nitrogen protection is required in the saponification reflux device. The national standard only mentions nitrogen protection, but does not specify how to carry out nitrogen protection. It brings a lot of inconvenience to the actual detection work. Different laboratories have adopted a variety of different schemes, which have played a certain role, but the operation is not very convenient, such as: placing a long glass tube from the top of the condensing reflux tube to the mouth of the round bottom flask; Use a nitrogen-filled balloon to cover the top of the condensate return line, etc. Some laboratories do not even carry out the nitrogen protection, and directly c...
