Description

Technical Field

[0001] This utility model relates to the field of experimental auxiliary instruments, specifically to a sample addition auxiliary device for a well plate. Background Technology

[0002] Well plates are common laboratory plastic plates. 96-well plates, with 96 small wells, are widely used in biological, chemical, medical, and pharmaceutical research due to their advantages such as high throughput, low material consumption, cost reduction, and ease of automation and standardization. However, the wells in a 96-well plate are small in area, relatively deep, and densely packed, with inconspicuous markings. For researchers, it is difficult to observe the bottom of the plate while seated. Furthermore, such a dense arrangement can easily cause visual fatigue, leading to incorrect, missed, or duplicate sample additions.

[0003] It is understood that existing 96-well plates suffer from several problems during use, including poor safety, inability to operate with one hand, and poor visibility. For example, CN215768630U, CN215975813U, and CN217733119U are frequently used with liquids such as water and organic reagents. Liquid contact with the circuit board not only poses safety issues but also affects its lifespan. Furthermore, CN212357205U, CN219972252U, and CN220393704U use marking strips and grooves to indicate the position of the 96-well plate, but this design often requires two hands for operation, making it inconvenient. In addition, there are issues with the base design lacking slope, affecting the operator's view during sample addition; and poor adaptability, as most sample addition aids use a fixed-height base, which cannot meet the needs of different types of 96-well plates.
