Problems solved by technology

However, there is no intelligent sample preparation device matching the low-temperature sample preparation tank at present. Existing experimenters must manually carry out sample setting and sample change operations, and cannot directly change samples at the working temperature (generally -120 to -180°C), which affects The efficiency of the experiment, and even if the temperature is further increased to change the sample, it is easy to cause the experimenter's fingers to be frostbitten, and the sample preparation is time-consuming and laborious

Embodiment

[0026] Freezing Substitution Mixer mainly includes sample installation components, quick release components, rotation components and intelligent control components.

[0027] The sample installation assembly includes a liquid tank 1, a bottom bracket 2, a holder 4, and a fixed shaft 14; the liquid tank 1 is set in the low-temperature tank of the refrigeration substitution equipment, and the bottom bracket 2 and the holder 4 are arranged in parallel, and fixed The shaft 14 is connected as a whole and cooperates with the liquid tank 1, that is, the whole can freely rotate around the liquid tank 1 or move axially, which is convenient for sample preparation and disassembly; the bottom of the liquid tank 1 is provided with a first groove 101, The second groove 102, the liquid tank 1 is detachably arranged in the low temperature tank of the refrigeration substitution equipment through the first groove 101, preventing it from rotating around the low temperature tank. When the sample m...

Abstract

The invention discloses a freezing replacement blending instrument which comprises a sample mounting assembly, a quick release assembly, a rotating assembly and an intelligent control assembly; the rotating assembly is arranged on the quick release assembly, the sample mounting assembly is arranged below the quick release assembly, and the sample mounting assembly is connected with the rotating assembly; and the intelligent control assembly is arranged on the rotating assembly, and intelligent programming control can be conducted on rotation of the rotating assembly through the intelligent control assembly. The freezing replacement blending instrument has the beneficial effects that (1) through the arrangement of the quick release assembly, the rotating assembly and the intelligent control assembly, intelligent sample shaking can be carried out on the sample mounting assembly at the working temperature without stretching a hand into a low-temperature tank of a freezing substitution instrument; and 2) by arranging the sample mounting assembly, after the quick release assembly is opened, an auxiliary test tube clamp can be used for conveniently, directly and quickly changing and matching samples at the working temperature without stretching a hand into the low-temperature tank of the freezing substitution instrument.

Description

technical field [0001] The invention relates to the technical field of freezing substitution system equipment, in particular to a freezing substitution mixing instrument. Background technique [0002] The freeze substitution system is a medical scientific research instrument used in the field of biology. It is mainly used for freeze substitution and gradient temperature technology. It can also be used for low temperature embedding and polymerization of resin. Its core is to provide a temperature controllable low temperature sample tank. However, there is no intelligent sample preparation device matching the low-temperature sample preparation tank at present. Existing experimenters must manually carry out sample setting and sample change operations, and cannot directly change samples at the working temperature (generally -120 to -180°C), which affects The efficiency of the experiment, and even if the temperature is further increased to change the sample, it is easy to cause ...
