Dismountable type constant temperature sleeve

Abstract

The invention discloses a detachable constant temperature sleeve, characterized by comprising a circular temperature-controlling jacket and a temperature-preserving coat, the circular temperature-controlling jacket is made of two layers of PVC plastic films, the interior forms, by means of thermal sealing, an access for circulation of a medium, and surrounding is thermally sealed, meanwhile, an input end is thermally sealed with an input pipe of a connector assembly and an output end is thermally sealed with an output pipe of the connector assembly; the temperature-preserving coat is made of temperature-preserving materials and has longer length and width than those of a circular water jacket which is covered within the temperature-preserving coat, the surface of the outer layer of the temperature-preserving coat is fixedly connected with a fastening tape. On account of usage of PVC plastic and general temperature-preserving materials, the cost is reduced; the fastening tape is designed to be convenient in detachment, and the invention meets the requirements of chromatographic posts with diverse forms of heights and lengths, in contrast to the current low temperature cold chamber or low temperature chromatographic cabinet, the invention is in no need of designated maintenance and is able to lessen consumption of the energy in the meantime.

Description

technical field [0001] The invention relates to a detachable thermostat jacket. Background technique [0002] Column chromatography is a method for separating and analyzing the substance according to the different characteristics of the different components of the separated sample moving in a certain matrix affected by their respective physical, chemical or biological characteristics. , mainly used in the processing and production of chemical industry, food, medicine and biological separation experiments. Since biomacromolecules and some organic compounds usually maintain activity in a specific temperature range, in order to ensure the activity of target molecules, it is necessary to keep the purification process in a suitable temperature environment. For example, in 1973, the research of J.W.Hastings et al. in the United States showed that the activity of the chromatographically purified riboflavin and luciferase complex in a cold room at -20°C was extended from a dozen se...

AI Technical Summary

Problems solved by technology

[0006] In order to overcome the problems of large investment and high power consumption in cold rooms or low-temperature chromatography cabinets in the prior art, and the use of water-cooled jacketed chromatography columns is likely to cause repeated waste of existing resources and increased costs, the present invention designs a detachable Thermostatic sleeve, the device can adapt to different cylinder diameters, realize uniform and stable temperature control of the cylinder, and can be spliced ​​to adapt to different cylinder lengths
