Embodiment Construction

[0031] The present invention will be described in detail below in conjunction with the accompanying drawings, but it should be pointed out that the implementation of the present invention is not limited to the following embodiments.

[0032] Such as Figure 1-Figure 6 As shown, a high-temperature heating pipette gun includes a pipette gun body 5, and a heating resistance wire 15, an insulating layer 16, and a casing 4 are sequentially arranged on the outside of the pipette 13 at the bottom of the pipette gun body 5 from inside to outside. , an exhaust channel 14 is arranged between the heat insulating layer 16 and the shell 4, the upper end of the exhaust channel 14 communicates with the inner cavity of the upper end of the liquid suction pipe 13 through the steam valve 11, and the bottom of the shell 4 is open. The lower end of the thermal insulation layer 16 is provided with a thermal insulation valve 19 connected by a spring shaft 18 .

[0033] The steam valve 11 is instal...

Abstract

The invention provides a high-temperature heating pipette and a using method thereof. The pipette comprises a pipette body; a heating resistance wire, a heat insulating layer and an outer shell are arranged on the outer side of a liquid sucking pipe at the lower part of the pipette body in sequence from inside to outside; an exhaust channel is formed between the heat insulating layer and the outershell; the upper end of the exhaust channel is communicated with the inner cavity in the upper end of the liquid sucking pipe through a steam valve; the bottom of the outer shell is of an open type;a heat insulating valve which is connected through a spring shaft is arranged at the lower end of the heat insulating layer. Compared with the prior art, the high-temperature heating pipette has the beneficial effects that the high-temperature heating pipette can be used for pipetting of high-temperature liquid in biological and chemical experiments, can precisely control the temperature of the liquid in a pipetting process, ensures that heat of the liquid does not lose, and can avoid crystallization of the liquid because of decrement of the temperature, so that an experimental error caused bypipetting is reduced.

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 ...
