Automatic cleaning device for probe of yeast freezing point osmotic pressure tester

Abstract

The invention provides an automatic cleaning device for a probe of a yeast freezing point osmotic pressure tester, and relates to the technical field of freezing point osmotic pressure testers. The automatic cleaning device for the probe of the yeast freezing point osmotic pressure tester comprises a probe assembly, wherein a probe seat is inserted into the top of the tester; a determination probe rod of the device can be automatically hidden in a protection cleaning seat when not used, so that the phenomenon that the determination probe rod is damaged by external force is avoided, and the durability is high; and the determination probe rod can extend out of the interior of the protection cleaning seat to determine a sample solution only when a sample cylinder is installed and positioned, and the determination probe rod can be cleaned and wiped by cleaning sponge in a surrounding manner during extension determination and retraction hidden protection, so that the use cleanness of the determination probe rod is ensured, the measured data is more accurate, and the problems that the determination probe of an existing freezing point osmometer is not provided with a protection structure so as to be easily damaged due to mistaken touch, collision or falling and the like, and when the determination probe is used, the probe rod cannot be automatically cleaned, and the use is troublesome are solved.

Description

technical field [0001] The invention relates to the technical field of freezing point osmometers, in particular to an automatic cleaning device for probes of yeast freezing point osmometers. Background technique [0002] Yeast is a eukaryotic receptor cell commonly used in gene cloning experiments. It is as convenient to cultivate yeast as to cultivate E. coli. In the process of yeast cultivation experiments, it is necessary to use a freezing point osmometer. An instrument that uses the principle of freezing point low pressure to measure the osmotic pressure of various solutions and body fluids. [0003] However, as far as the current freezing point osmometer is concerned, its measuring probe always leaks outside the base body, without a protective structure, it is easy to be damaged due to accidental touch, bump or drop, etc., which increases the cost of use and has poor flexibility. When the measurement probe is used, the probe rod cannot be cleaned automatically. In orde...

[0003] However, as far as the current freezing point osmometer is concerned, its measuring probe always leaks outside the base body, without a protective structure, it is easy to be damaged due to accidental touch, bump or drop, etc., which increases the cost of use and has poor flexibility. When the measuring probe is used, the probe rod cannot be cleaned automatically. In order to ensure the accuracy of the data, it is necessary to manually test the probe rod every time, which is cumbersome, cumbersome and not very practical.
