Description

Technical Field

[0001] The utility model relates to the technical field of biological experimental instruments, in particular to a dye liquid collecting device. Background Art

[0002] When conducting medical experiments, a sampler is needed to take the dye solution for staining the sample. The existing dye solution sampler is usually a rubber-tipped dropper, which is also called a rubber-capped dropper. It is an instrument used to absorb or drip a small amount of liquid reagent. The rubber-tipped dropper consists of a rubber cap and a glass tube. There are several types, such as straight, straight with a buffer ball, and curved with a buffer ball.

[0003] After a common dropper sucks up liquid, its liquid suction port is directly exposed to the air, which not only makes the liquid easily come into contact with impurities in the air, but also makes the liquid collected in the dropper easy to drip due to accidentally touching the rubber sleeve again, causing liquid splashing.
