Description

[Detailed Description of the Invention] The present invention relates to a solvent spray complete instrument cleaning tool for sample tubes and the like having a small inner diameter.

For more details, please refer to Nuclear Magnetic Resonance NMR and Electron Spin R!
! The present invention relates to a solvent spray set and equipment cleaning tool for ESR sample tubes, measurement cells for ultraviolet absorption spectra UV and infrared absorption spectra 1R, and containers with small inner diameters such as various vials, or containers whose surfaces should not be damaged.

A sample tube with a small inner diameter as described above cannot be sufficiently cleaned even with a thin brush, and there is a risk that the inner surface of the measurement cell may be damaged by brush cleaning.

There is also a method of cleaning such containers that are difficult to clean using ultrasonic waves, but the cost of the equipment is high and it is still difficult to clean them thoroughly.

As a result of various studies on cleaning methods for personal record containers, the inventor of the present application has developed a device with a simple structure that is inexpensive, has extremely high cleaning efficiency, and has completed the invention of the present application.

That is, the present invention consists of a 1-proof container having an open portion at the top, and a means for sealing the opening having at least two through holes, and at least one of the through holes has a solvent inlet pipe hermetically sealed therein. A capillary tube for a nozzle is connected to the tip of the introduction tube, and the capillary tube protrudes from the other through holes to the outside of the container, leaving a slight gap between the outer periphery of the capillary tube and the inner wall of the through hole. , relates to a solvent spray set instrument cleaning tool characterized in that either the container or the sealing means is provided with a suction hole.

The cleaning tool of the present invention will be explained in more detail with reference to the drawings.

In FIG. 1, a pressure container 1 having an open section 2 is sealed by a sealing means 3. As shown in FIG.

The sealing means 3 has through holes 4 and 7, and a solvent introduction tube 5 is airtightly attached to the through hole 4.

A thin tube for a nozzle is connected to the tip of the tube 5 and protrudes from the through hole 7 to the outside.

There is a gap 8 between the thin tube 6 and the through hole 7, and the container 1 is provided with a suction hole 9.

The container 11 to be cleaned is placed in the -L of the through hole 7 with the open part 1 facing downward, and is supported by the container support 10 if necessary.

A container to be cleaned 11 with a flat opening is placed on the sealing stage 3 so that the nozzle thin tube 6 is inside the container, and a suction means such as a water pump (not shown) is connected to the suction hole 9. and make it stick.

After confirming that the inside of the container has been depressurized, a suitable cleaning solvent is injected from the solvent inlet tube 5 using a dropper I- or the like.

As shown in FIG. 2, the solvent passes through the nozzle tube 6, is sprayed into the container 11 to be cleaned, flows down while cleaning the container wall, and is sucked into the container 1 through the gap 8.

The pressure-resistant container used in the present invention is made of solvent-resistant glass,
Those made of plastic, ceramic, metal, etc. are suitable, and those made of glass are usually suitable.

As a means of sealing the opening, rubber, plastic, wood, glass, metal, etc. can be pressed into the inside of the opening L-1, rubbed against the end surface of the opening L-1, or screwed into the outside of the opening L-1 with a cap. , or any other means that can be airtightly connected to the pressure vessel may be used.

Most preferably a rubber stopper is used.

The through-hole 4 is bored in accordance with the outer diameter of the solvent introduction tube 5 so as to be airtight.

It is convenient to make the upper end of the solvent inlet tube 5 funnel-shaped so that the solvent remains there.

Glass is usually used as the material for this tube, but it may also be made of plastic, ceramic, metal, or other materials as long as they are solvent resistant.

Further, the through hole 4 may be vertical or oblique depending on the size of the opening 2.

The nozzle thin tube 6 is preferably one that can be easily adjusted or replaced according to the inner diameter and length of the container 11 to be cleaned.

Plastic, rubber, glass, metal, or any other solvent-resistant material may be used, but plastic or rubber is preferred because the length can be changed freely, and Teflon (product name), which has excellent solvent resistance, is suitable. ) is particularly preferred.

The inner diameter of this nozzle thin tube varies depending on the inner diameter and volume of the container to be cleaned, but for example, an NMR test tube (inner diameter 4.2 m)
m length 18cm), approximately 0.8mm to 2mm
If it is thinner than this, it will be difficult to spray, and if it is thicker than this, the amount of solvent used will be large, which is not appropriate.

The distance between the tip of the nozzle capillary tube and the bottom of the container to be cleaned varies depending on the degree of pressure relief, the inner diameter of the container to be cleaned, etc. You can move it and adjust it as appropriate.

For example, when using the aforementioned NMR test tube and nozzle capillary tube with an inner diameter of 1.0 mm and cleaning with a normal water pump (12 mmHg), the tip of the nozzle capillary tube should be within about 20 mm from the bottom of the container to be cleaned. It's good to do that.

By setting the gap 8 to an appropriate size, the nozzle capillary tube is fixed at an arbitrary position due to friction caused by point contact with the inner wall of the gap 8, and does not slip down.

The suction hole 9 may be provided in either the pressure container 1 or the sealing means 3.

Since the present invention has the above-mentioned configuration, the nozzle thin tube can be guided deep into the container to be cleaned, and it exhibits outstanding power in cleaning long and narrow containers.

In addition, it can be cleaned effectively with a small amount of solvent, and it can be opened by changing the diameter of the nozzle capillary (thick inner diameter), the diameter of the through hole, or the distance between the tip of the nozzle capillary and the bottom of the container to be cleaned. Containers of various shapes with flat sections can be thoroughly cleaned.

The number of through holes and nozzle thin tubes is not limited to one, and multiple nozzle thin tubes can be used to simultaneously perform cleaning operations on multiple containers to be cleaned using the same solvent or different solvents. It is.

Furthermore, since the structure is simple as described above, there is a great advantage that failure is almost impossible.

Furthermore, since the dead space is small, it is extremely easy to exchange solvents even when washing the same container with different solvents, and mixed solvents can be used completely freely.

The cleaning tool of the present invention is inexpensive, extremely easy to assemble, repair, and handle, and has extremely high cleaning efficiency. Furthermore, by suctioning directly after solvent cleaning, it is possible to dry the cleaning container using airflow. It's convenient.

An embodiment of the present invention is shown below.

Parts used in the example: Water pump, pressure-resistant rubber tube, rubber stopper, glass funnel (5-10ml/Jl), Teflon tube (20-30cm)
m, inner diameter 1.0 mm, outer diameter 1.5 mm), wire (10
cm < leprosy), pressure-resistant suction bottle (for 1,000 m1).

Assembling the cleaning tool: (1) Drill large and small holes in the rubber stopper.

Make a large hole diagonally from the edge of the rubber stopper to the center of the bottom so that it matches the outer diameter of the bottom of the funnel.

A small hole is slightly larger than the outside diameter of the Teflon tube to be used, and is perpendicular to the center of the rubber stopper.

(2) Narrow the bottom end of the funnel with a burner and insert a Teflon tube into it.

At this time, by heating both with a burner or the like while inserting them, they can be easily brought into close contact.

(3) Connect the other end of the Teflon tube to the vertical opening in the center from the lower end -L
Put it in the direction.

(4) Attach a rubber stopper with the following details to the top of the suction bottle, and connect the suction bottle to the water pump using a pressure-resistant rubber tube.

(5) Insert a wire with one end spiraled close to the edge of the rubber stopper so that the spiral part is above the Teflon tube.

Although this wire is used to support the container, it is desirable that it be freely attachable and detachable.
