Description

Non-flat container is weighed and is used rack

Technical Field

The utility model belongs to the technical field of glass instrument strorage device, especially a non-flat container is weighed and is used rack.

Background

Centrifuge tubes, test tubes, round-bottomed flasks and the like are common non-flat-bottomed containers in laboratories, and are not easy to independently and stably place on a balance during weighing, and liquid is not easy to directly weigh; when solid materials are weighed, the solid materials need to be transferred by means of weighing dishes or weighing papers and other instruments, and the risks of medicine pollution and waste are increased.

Disclosure of Invention

Not enough to prior art exists, the utility model provides a non-flat container is weighed and is used rack has solved the unstable problem of placing that exists when weighing centrifuging tube, test tube, round flask etc..

The utility model aims at being realized by following technical scheme:

a non-flat-bottom container weighing rack is characterized in that a main body is a cylinder and can be placed on a balance; the upper surface of the cylinder is an inwards concave cambered surface, and the inside of the cylinder is provided with object placing holes with different diameters.

The diameter and the number of the storage holes can be customized according to the size of the container used, and the bottoms of the storage holes are not perforated.

The cylinder is made of EVA materials.

The concave radian of the concave cambered surface is consistent with the radian of the bottom of the round flask.

The utility model has the advantages that: the utility model provides a pair of non-flat container is weighed and is used rack, through the concave cambered surface that is equipped with on the cylinder upper surface and the inside different diameters that are equipped with of cylinder put the thing hole, the unstable problem of placing that exists when having solved centrifuging tube, test tube, round flask etc. and weighing, conveniently weigh and use, avoided the extravagant risk with the pollution of medicine.

The present invention will be further explained with reference to the drawings and examples.

Drawings

fig. 2 is a schematic top view of the present invention.

Wherein: 1-a body; 2-placing holes; and 3, numbering the storage holes.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

As shown in figure 1, a non-flat container is weighed and is used rack, main part 1 is the cylinder, and the material is EVA, and the size can be customized, the upper surface of cylinder is the indent cambered surface, can fix round flask or other round bottom containers better, and the inside thing hole 2 of putting that is equipped with different diameters of cylinder, and the size and the quantity of putting thing hole 2 can be customized according to the size that uses the container, and put 2 bottoms in thing hole and do not punch through, centrifuging tube or test tube drop from the bottom when preventing to remove. In FIG. 2, the diameter of the bottom surface of the bracket 1 is 180mm, and the height is 100 mm; the number of the object placing holes is 9, and 2-1 to 2-9 correspond to different hole diameters respectively; the diameter of the openings of the placing holes 2-1 and 2-7 is 10mm, the depth is 20mm, and 1.5 ml of centrifuge tubes and 2 ml of centrifuge tubes and test tubes with the specification of 10mm multiplied by l00 mm can be placed in the placing holes; the diameters of the openings of the placing holes 2-3 and 2-5 are 13mm, the depth is 30mm, and 5 ml of centrifuge tubes can be placed; the diameter of the openings of the placing holes 2-2 and 2-6 is 16mm, the depth is 40mm, and 10 ml centrifuge tubes and 15 mm multiplied by l50 mm test tubes can be placed; 2-8 of the object placing holes have the diameter of 20mm and the depth of 45mm, and test tubes with the specification of 18 mm multiplied by l80 mm and 20mm multiplied by 200 mm can be placed; the diameter of the opening of the object placing hole 2-4 is 29mm, the depth is 50mm, and a 50 ml centrifuge tube can be placed in the object placing hole; 2-9 the diameter of the opening is 50mm, the depth is 50mm, and a 25-150 ml round-bottom flask can be stabilized. The upper surface of the bracket is an inwards concave cambered surface, and a large-capacity flask can be placed in the bracket.

When the non-round bottom container is used for weighing liquid or solid samples, the utility model is firstly placed on a balance, the weighing container is placed in the corresponding object placing hole, the balance is reset to zero, the samples are slowly moved into the weighing container, and when the reading of a target is approached, the liquid can be dripped to the required weight by a rubber head dropper; solid powder and the like are slowly added to the desired value using a spoon. After weighing, can remove in the lump together with the utility model discloses, weigh the rack use of container as this non-round bottom.

It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not limitations to the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. Not all embodiments are exhaustive. All obvious changes or variations led out by the technical scheme of the utility model are still in the protection scope of the utility model.
