Abstract

The invention provides a high-temperature heating pipette gun and its use method. The pipette gun includes a pipette gun body, and a heating resistance wire and a thermal insulation layer are sequentially arranged on the outer side of the suction tube at the lower part of the pipette gun body from inside to outside. 1. The shell, an exhaust channel is arranged between the heat-insulating layer and the shell, the upper end of the exhaust channel communicates with the inner cavity of the upper end of the suction pipe through a steam valve, the bottom of the shell is open, and at the bottom of the heat-insulating layer The lower end is provided with a heat preservation valve connected by a spring shaft. Compared with the existing technology, the beneficial effects of the present invention are: the present invention can be used for pipetting high-temperature liquids in biochemical experiments, can accurately control the temperature of the liquid during the pipetting process, ensures that the heat of the liquid is not lost, and can avoid Some liquids crystallize as the temperature decreases, thereby reducing experimental errors caused by pipetting.

Description

technical field [0001] The invention relates to a biological and chemical precision experimental equipment, in particular to a high-temperature heating pipetting gun and a using method thereof. Background technique [0002] The pipette gun is a kind of pipette, which is often used for pipetting a small amount or a small amount of liquid in the laboratory. Compared with simple pipetting equipment such as pipettes, it has higher accuracy and can greatly reduce experimental errors. Especially for experiments with high error requirements, only pipettes can be used, and for some analytical equipment, only pipettes can be used. There are also some multi-channel pipettes on the market, which can take multiple samples at the same time. The operation is more convenient, but the relative experimental error is also greater, and for some analytical equipment such as high performance liquid chromatography, it can only be used with a single-channel pipette. Therefore, this pipette gun ...
