Technical Field

The utility model relates to a clear up equipment technical field, concretely relates to clear up colour comparison tube stopcock fixing device of usefulness.

Background

In the process of determining the total nitrogen and total phosphorus content of a water sample, a colorimetric tube with a ground plug is often placed into an autoclave to digest the sample, and before the colorimetric tube is placed, the ground tube plug needs to be plugged and wound tightly by gauze and a cotton rope so as to prevent liquid in the tube from being sprayed out to influence the determination result in the high-temperature high-pressure digestion process.

The sealing method for preventing liquid in the colorimetric tube from splashing in digestion at high temperature and high pressure in the prior art is commonly used, and is characterized in that a sealing film is bound on the tube opening of the colorimetric tube by using a rubber band, but in the digestion process, the rubber band is very easy to lose elasticity under the environment of high temperature and high pressure, the sealing film cannot be continuously fixed, the sealing film is caused to slide down, and the sample is likely to overflow or cross-contaminate, so that the experimental result is influenced.

In the digestion process, the pressure in the tube is far insufficient to cause the color comparison tube to burst, but the opening of the tube must be sealed to prevent liquid from splashing and cross contamination, the traditional method is to bind the tube opening with gauze and cotton ropes, and the step is laborious and time-consuming in the operation of a large number of samples and affects the experiment progress; the sealing film is bound by the rubber band, the rubber band is softened due to high temperature and high pressure, the sealing film falls off, and the sealing film can be used only once, so that materials are wasted.
