An intelligent pipette holder

Abstract

The invention discloses an intelligent pipettor support. The intelligent pipettor support comprises a supporting frame and a base for erecting the supporting frame; the supporting frame is composed of a round rotating disc and a supporting rod for fixing the round rotating disc, a round hole matched with the supporting rod is formed in the base, a plurality of grooves are formed in the edge of the round rotating disc and divided into multiple subregions according to measuring ranges, and each groove corresponds to one indicator lamp; a pipettor recognition system is arranged at the top of the supporting frame and comprises a power module, a control module, a storage module, an alarm module, RFID readers arranged in all the subregions, RFID labels arranged in pipettors, a reference position detecting module and a display module, wherein the storage module and the alarm module are connected with the control module, and the indicator lamps are connected to the control module. The intelligent pipettor support has the advantages of being simple, convenient to operate, and capable of greatly saving experience space, effectively simplifying experiment operation procedures and improving the working efficiency.

Description

technical field [0001] The invention relates to a support for placing experimental equipment, in particular to an intelligent support for placing pipettes, samplers and the like in a laboratory. Background technique [0002] The pipette is a precision device for liquid transfer and sampling commonly used in clinical diagnostic laboratories, biotechnology laboratories, laboratories of large and medium schools, laboratories in the chemical industry, etc. Since pipettes are precision instruments, most of them are relatively expensive. In order to prevent contamination and damage, the pipettes are usually placed on the pipette holder after use. [0003] There are several common types of pipette holders commonly used in existing laboratories: (1) "L" shape, including hanging rods and support rods arranged at both ends of the hanging rods; (2) "branch type" disc type The common point of the above-mentioned two kinds of supports is that the whole support body belongs to a fixed st...

Problems solved by technology

[0004] In order to solve the space problem, the Chinese utility model patent CN203525741U discloses a bracket capable of suspending multiple pipettes, but this type of pipette bracket still has the following disadvantages: (1) because there are too many pipettes placed , this kind of pipette holder lacks the system positioning function, it is difficult for the experimenter to quickly find the target pipette with the desired range in a short period of time; (2) due to the large number of placed pipettes, the If there are many pipettes placed in a certain area of ​​the bracket, the center of gravity of the bracket will often be shifted, and it is easy to tip over and overturn and damage the pipette; (3) the site, support rod and fixed plate disclosed in this patent They are in a fixed state, which makes it inconvenient for the staff to take and place the pipettes; (4) In the teaching experiment, due to the lack of experimental teachers, the number of experimental teachers equipped in the experiment with a large number of students is at most 2 -3 people, so it takes a lot of time for the experimental teacher to manage so many pipettes; (5) The more important point is that the pipette is a precision instrument for liquid transfer and sampling, and the volume of the liquid measured by the pipette The accuracy directly affects the reliability and accuracy of the experimental results

In real life, experimenters, especially beginners who have just stepped into the experiment, often forget to adjust the pipette to the maximum range when the experiment is over due to lack of good experimental habits. The volume error between the displayed range of the pipette and the actual measured liquid increases, which seriously affects the accuracy and reliability of the experimental results. It is also very tedious and time-consuming work for the experimental teacher to detect whether each pipette has been reset.
