Background

In laboratory experiments, it is often necessary to add a volume of a semi-solid reagent, such as glycerol, Tween, etc., in order to prepare a solution or to prepare a particular reagent. Since these semisolid reagents are relatively viscous, the following problems exist when aspirating them off with a conventional tip:

semi-solid reagent is absorb with ordinary rifle head in the laboratory mostly, because more viscous, the volume of predicting can not once only be absorbed to the rifle head of using at ordinary times, often can cause the production bubble because hardly control suction with the hand at the in-process of absorbing, makes the volume of absorbing inaccurate, can only absorb again. In order to better absorb viscous semi-solid such as glycerin and soil temperature, an operator in a laboratory usually selects to cut off a part of the tip of a common small-diameter gun head conventionally used in the laboratory by using scissors, which is very inconvenient because the semi-solid liquid such as glycerin and soil temperature is very viscous, and a certain volume of semi-solid is finally absorbed although the semi-solid liquid is subjected to processes such as shearing the gun head, slowly absorbing and the like, and finally the volume actually used can not reach the expected theoretical value because of the residue of the inner wall when the solution is beaten; because the texture is sticky, it is often difficult to clean completely, and there is a risk of contamination when another reagent is removed. The process of transferring the semi-solid reagent is time-consuming and difficult to operate, and the reagent cannot be absorbed in a sufficient amount, so that the pollution probability of a liquid transfer gun is increased, the reagent is not easy to clean, and the subsequent experimental result is influenced; in view of the above, there is a need for improvements in the prior art to meet the current requirements for use of pipette tips.
