在实验室取用固体药品时,如果是粉末状的要用药匙取出,如果需用量多,则还要换用纸槽将药品送入试管底部,需用量少,则用药匙另一端取出并将其送入试管。用此药匙取用药品,往往易将试管壁弄脏,且因药匙进不了试管易造成药品损失,若还需用纸槽则更增加麻烦,同时,若取用块状或颗粒状药品,则又要改用镊子,取用才更方便。为克服上述缺点,笔者设计了一种多用取药钳。该钳无论取用粉末状固体还是取用块状药品,也无论取用量多还是少,都能方便自如使用。
In the laboratory access to solid drugs, if the powder is to use the spoon to take out, if the amount required, you also need to change the paper trough to the bottom of the test tube into the tube, less dosage, then use the other end of the key taken and Put it in the test tube. With this medicine spoon to take drugs, tend to easily test tube wall dirty, and because the spoon into the test tube can easily lead to drug loss, if you still need to use the paper trough is more trouble, and take the block or granular Drugs, then have to use forceps, access is more convenient. In order to overcome the above shortcomings, I designed a multi-purpose withdrawal forceps. The pliers whether taking powdered solid or taking block drugs, no matter take more or less, can be easily used.
