Embodiment 1

[0022] When implementing the present invention, if using a suction tip with a volume of 1 mL, such as figure 1 As shown, the scale starts from the small port of the tip 3, the volume scale capacity of each small interval is 0.05mL, and the total volume is 1mL. Put a larger steel ball on the large port, bake and stretch it with an alcohol lamp to form a spherical protrusion. After taking out the steel ball, close the large port. Connect with the corresponding bladder head 1. It can measure various solutions and reagents.

Embodiment 2

[0024] When implementing the present invention, if using a suction tip with a volume of 200 μL, such as figure 1 As shown, the scale starts from the small port of the tip 3, the volume scale capacity of each small interval is 10 μL, and the total volume is 200 μL. The expanded sphere 2 is separate from the suction head, and the expanded sphere 2 is connected to the suction head through threads. Connect the large port with the corresponding bladder head 1. It can measure various solutions and reagents.

[0025] The invention is a pipette applied to experimental analysis. It uses the suction head as the main body of the pipette, which is not easy to be broken and damaged; it is convenient to disassemble and wash; it takes up less space when sterilizing; it is convenient and flexible to use. The diameter of the spherical container on the upper part of the pipette body is much larger than the diameter of the lower part of the tip. When used together with the capsular rubber tip...

Abstract

The invention discloses a device capable of avoiding damage of a pipette nozzle. The device comprises a sucker with an expansion ball on the top and a saccular rubber head, a sucker body is cylindrical, the section with the expansion ball is connected with the saccular rubber head, a tip is arranged at the lower end of the sucker body, and scales are evenly distributed on the outer surface of the sucker body. The sucker made of plastics is used as a body of a pipette, so that damage to the pipette nozzle is avoided; the sucker is large in inner diameter, thereby being convenient to detach and wash; the pipette is shortened, thereby being less in occupied space when sterilized with a sterilizing pot; the device is convenient and flexible to use.

Description

technical field [0001] The invention relates to laboratory inspection and analysis equipment, in particular to a device for avoiding damage to pipette nozzles. Background technique [0002] The pipettes commonly used in laboratories are generally made of glass and are prone to breakage during transportation; especially the drippers are relatively thin and are more likely to be broken during use and transportation; the inner diameter of the pipe is too small, which often results in incomplete washing; and When the ear-suction ball is used together, due to the excessive suction of the ear-washing ball, the experimental solution is often sucked into the ear-washing ball, causing the ear-washing ball to be corroded and polluted. Although some pipettes are designed with a pot-bellied shape, this can be partially avoided. However, these pipettes are not convenient and flexible to use because the tube body is too long. The space occupied by the sterilizing pot is too large during...
