Sequencing batch sealed thermostatic reaction device

Abstract

The invention discloses a sequencing batch sealed thermostatic reaction device which comprises a sealed device box body, a plurality of conical flask reactors fixed in the device box body, a pluralityof stirrers correspondingly arranged in the device box body and located at the bottoms of the conical flask reactors, and a temperature adjusting module disposed on the left and right side panels ofthe box body. A master switch, a stirrer switch, a temperature display and control panel, a plurality of timers, and a display panel are disposed on the front side of the device box body. The top cover of the device box body is provided with top cover through holes sealed by screw caps. The bottle mouths of the conical flask reactors are in sealed connection with an incoming tube, a sampling tubeand a vent tube. The incoming tube is connected to the corresponding top cover through hole. The sampling tube is connected to a corresponding sampling syringe through the front and rear side panels of the housing. The device box is not required to be opened during the whole reaction so as to minimize the interference of the sampling on reaction conditions. The sample incoming and sampling are achieved by catheters so as to simplifie the experimental operation.

Description

technical field [0001] The invention relates to simplification of laboratory batch reaction operation and precise control of reaction conditions, in particular to a sequence batch type closed constant temperature reaction device. Background technique [0002] In the process of batch chemical reaction research based on small reaction vessels such as Erlenmeyer flasks in the chemical laboratory, it is the basic principle to ensure smooth sampling process and constant reaction conditions.

[0002] In the process of batch chemical reaction research based on small reaction vessels such as Erlenmeyer flasks in the chemical laboratory, it is the basic principle to ensure smooth sampling process and constant reaction conditions. Sometimes too many batch reactions can easily lead to tedious sampling process. Severely interfere with the reaction conditions in the reaction space and affect the experience of doing experiments, such as shaking table reactions, frequent sampling leads to constant communication between the inside of the shaking table and the outside world, causing fluctuations in experimental conditions. When setting up multiple reactors, it is necessary to manually Each reactor is equipped with a timer. If it is not well marked, it is easy to confuse the sample. It is necessary to design a reaction device that can not only accurately and rapidly continuously sample but also not affect the experimental conditions due to the sampling process.
