Description

Ultra-clean table with magnetic base pipette, pipette holder, storage tray

[0001] The present invention relates to a magnetic base suction pipe, a pipette holder, and a storage tray for a clean bench.

Background technique

[0002] In scientific research experiments that provide a sterile environment in a clean bench, pipettes, pipettes, and pipette tips, pipette tips, alcohol cotton balls, culture caps, lighters, and ophthalmologists are often used in experiments. Laboratory equipment. Wherein, using a pipette to transfer the test solution between test tubes, test bottles, flasks, flasks, measuring cylinders, measuring cups, measuring flasks, and flasks; using a pipette (rotating aspiration adjustment dial, preset aspiration amount, and Load the tip. Transfer the test solution quantitatively between test vessels, test vials, vials, flasks, beakers, graduated cylinders, measuring cups, measuring flasks, and flasks. After sucking different volumes of the experimental solution, the test solution of different functions can be transferred by simply changing the tip; the pipette tip, the pipette tip, the alcohol cotton ball, the culture cap, the lighter, the ophthalmology are required to be repeated several times in the experiment. Auxiliary laboratory equipment used.

[0003] Straws As a tool often used in scientific research experiments, a straw can be reused if it absorbs the same solution. If the straw is placed horizontally, the space occupied by the clean bench is too large. Moreover, in the case where the glass pipette is placed horizontally, it is likely to cause contamination of the straw. This requires people to prepare the vertical placement of the device for the straw in the clean bench. The vertical placement of the straw inside the clean bench is usually accomplished by placing a test tube holder with a sterile test tube on the surface of the clean bench and inserting the pipette vertically into the test tube.

[0004] As a tool for quantitatively transferring a solution in scientific research experiments, the pipette is used at a high frequency, and a pipette equipped with a certain tip is repeatedly used after sucking the same experimental solution. Since the pipette occupied by the horizontal position of the pipette is too large and the liquid pipette has been sucked, the liquid remaining in the pipette in the last pipetting may flow to the pipette and the tip connection portion. Causes contamination of the pipette. This requires people to prepare a vertically placed pipette holder for the pipette in the clean bench. To ensure the stability of the pipette holder after placing the pipette, the pipette holder generally has a larger base area.

[0005] In the need to use dropper tips, pipette tips, alcohol cotton balls, culture caps, lighters, ophthalmology and other experimental equipment, people usually put these experimental equipment in the relevant containers, or will These experimental small equipment were scattered on the countertop of the clean bench. [0006] However, the test tube rack, the pipette rack and the container for accommodating the above experimental small equipment are respectively placed on the table surface of the ultra-clean table, or the above-mentioned experimental small equipment is directly placed on the table surface of the ultra-clean table, which is larger The occupation of the countertop space of the ultra-clean platform has led to the crowding of experimental samples, experimental reagents and laboratory equipment on the surface of the ultra-clean bench where the original area is not large. The crowding of experimental samples, experimental reagents and laboratory equipment on the surface of ultra-clean benches will hinder the rapid and efficient implementation of scientific research experiments and affect the accuracy and accuracy of scientific research experiments. Serious paralysis can lead to the failure of scientific research experiments.
