Abstract
Description
Technical Field
[0001] This utility model relates to a sample loading device for a liquid chromatograph, belonging to the technical field of liquid chromatograph loading equipment. Background Technology
[0002] Currently, liquid chromatography samples require the use of a syringe to inject the sample into the vial. When inserting the syringe into the vial, the needle can easily prick the hand. Furthermore, since the vials are made of glass, they are easily broken during transportation, requiring staff to prepare multiple vials for replacement, which is inconvenient for staff operation.

[0010] Reference Figure 1 Figure 2 Figure 3 Figure 4 A sample loading device for a liquid chromatograph includes a loading bottle 1, an anti-slip rubber tray 2, a label 3, a sealing cap 4, a locking ring 5, a protective cover 6, and a connecting block 7. The device is characterized in that: the anti-slip rubber tray 2 is connected to the center of the lower surface of the loading bottle 1; the label 3 is connected to the upper part of the side surface of the loading bottle 1; the sealing cap 4 is inserted into the center of the upper surface of the loading bottle 1; and the locking ring 5 is connected to the perimeter of the upper surface of the sealing cap 4. A protective cover 6 is inserted at the center of the outer surface. Connecting clips 7 are symmetrically connected to the upper side surface of the protective cover 6. The container bottle 1 includes an outer bottle 1-1, capsules 1-2, graduations 1-3, and rubber pads 1-4. Capsules 1-2 are symmetrically inserted at the center of the side surface of the outer bottle 1-1. Graduations 1-3 are located at the center of the front of the side surface of the outer bottle 1-1. Rubber pads 1-4 are connected to the four edges of the upper surface of the outer bottle 1-1. An anti-slip rubber disc 2 is connected to the lower surface of the outer bottle 1-1. The outer bottle 1-1 has threads at the upper edge of its outer surface. The sealing cap 4 includes a round cap 4-1, a countersunk hole 4-2, a rubber stopper 4-3, and a needle 4-4. The round cap 4-1 has a countersunk hole 4-2 at its lower surface center. The rubber stopper 4-3 is inserted into the center of the upper surface of the countersunk hole 4-2. The needle 4-4 is inserted through the center of the upper surface of the rubber stopper 4-3. The round cap 4-1 is tightened onto the upper surface of the outer bottle 1-1 to seal the rubber gasket 1-4. The needle 4-4 is cross-shaped. The protective cover 6 includes a cap 6-1, a rubber ring 6-2, a toothed ring 6-3, and a rubber head 6-4. The rubber ring 6-2 is connected to the lower surface of the cap 6-1 around its perimeter. Several toothed rings 6-3 are evenly distributed vertically around the inner side surface of the cap 6-1. The rubber head 6-4 is connected to the center of the inner upper surface of the rubber ring 6-2. The cap 6-1 is inserted into the clamping ring 5. The needle 4-4 is inserted into the rubber head 6-4. The toothed ring 6-3 is at an upward angle.
[0011] In use, the staff first holds the outer bottle 1 on the container bottle 1 with one hand and uses the index and middle fingers of the other hand to hold the cap 6-1 on the protective cover 6. At the same time, the index and middle fingers are placed under the connecting block 7 and pulled upwards to separate the cap 6-1 from the locking ring 5 and the rubber head 6-4 from the needle 4-4 on the sealing cap 4. Then, press the capsules 1-2 on both sides and insert the needle 4-4 into the liquid. Then, release the capsules 1-2 to allow the liquid to be drawn into the outer bottle 1-1 through the needle 4-4. The staff can control the amount of liquid drawn by watching the scale 1-3. Then, step the cap 6-1 on the round cap 4-1 and insert the cap 6-1 into the locking ring 5 and seal it with the rubber ring 6-2. At the same time, insert the needle 4-4 into the rubber head 6-4 to prevent the liquid sample from being squeezed out. Finally, the staff writes the sample name on the label 3.
[0012] During transportation, the outer bottle 1-1 is inserted into the slot on the pallet, and the anti-slip rubber plate 2 is clamped in the slot to prevent the outer bottle 1-1 from moving and colliding with the pallet during transportation. At the same time, the rubber pad 1-4, rubber stopper 4-3, rubber ring 6-2 and rubber head 6-4 can be removed to seal the outer bottle 1-1 to prevent the sample from flowing out.
[0013] During testing, the staff rotates the round cap 4-1 to remove it from the outer bottle 1-1, and finally places the outer bottle 1-1 into the liquid chromatograph for testing.
[0014] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
