Description
技术领域 technical field
本实用新型涉及化学器械领域，具体涉及一种胶头滴管。 The utility model relates to the field of chemical instruments, in particular to a rubber dropper.
背景技术 Background technique
滴管主要用于转移少量的化学试剂，是实验中常用仪器之一，通常由橡皮胶头和尖嘴玻璃管构成。使用滴管时，用手指捏紧橡皮胶头，赶出滴管中的空气，然后把滴管伸入试剂瓶中，放开手指，试剂即被吸入，再次挤压橡皮胶头即可，由于实验中需要转移的液体通常为化学试剂，甚至是具有极强腐蚀性的化学试剂，在转移化学试剂时若不小心吸入剂量过多，容易使试剂进入到橡皮胶头中，或者平放时残留化学试剂亦容易倒流至橡皮胶头中，造成胶头的腐蚀、发硬、变粘变黑甚至腐烂泄露影响使用，此时便需要频繁的更换橡皮胶头，造成资源浪费的同时也容易对环境产生污染。而且，目前市场上所用的滴管都只具有滴加转移试剂的功能，若要粗略定量加入试剂，则无法实现，此时需要更换仪器，给实验操作造成不便。 The dropper is mainly used to transfer a small amount of chemical reagents. It is one of the commonly used instruments in experiments. It usually consists of a rubber tip and a pointed glass tube. When using the dropper, pinch the rubber head tightly with your fingers to drive out the air in the dropper, then put the dropper into the reagent bottle, let go of your finger, the reagent will be sucked in, just squeeze the rubber head again, because The liquid that needs to be transferred in the experiment is usually a chemical reagent, even a highly corrosive chemical reagent. If you accidentally inhale too much dose when transferring the chemical reagent, it is easy to cause the reagent to enter the rubber head, or leave a residue when it is placed flat. Chemical reagents are also easy to flow back into the rubber head, causing the rubber head to corrode, harden, become sticky and black, and even rot and leak, which will affect the use. At this time, the rubber head needs to be replaced frequently, which causes waste of resources and is easy to damage the environment. produce pollution. Moreover, the droppers currently on the market only have the function of dripping and transferring reagents. If the reagents are roughly quantitatively added, it cannot be realized. At this time, the instrument needs to be replaced, which causes inconvenience to the experimental operation.
