Description

Prevent centrifugal bottle and weigh holding device who emptys

Technical Field

The utility model relates to a chemistry experiment instrument technical field specifically is a prevent that centrifugal bottle weighs holding device who emptys.

Background

In laboratory studies and experiments, the use of a centrifuge requires symmetrically placing centrifuge bottles of the same weight to complete the centrifugation operation, and thus requires weighing the centrifuged medicine. Because the bottom end of the centrifugal bottle is conical, the centrifugal bottle cannot be placed vertically, so that accurate reading and weighing cannot be realized, and even safety accidents caused by the fact that experimental medicines are scattered due to careless operation can be caused.

Disclosure of Invention

The utility model aims at: the design is a container for preventing centrifugal bottles from weighing and dumping, which is used for fixing the centrifugal bottles and preventing the phenomenon of dumping in the weighing process.

The utility model provides a prevent that centrifugal bottle weighs holding device who emptys specifically includes a circular base and a fixed bolster that is used for holding centrifugal bottle.

Preferably, the fixing support main body is cylindrical, and a layer of EVA anti-slip pad is bonded on the contact surface of the base and the weighing balance.

Preferably, the diameter of the base is about 5cm, the diameter of the fixing support is about 3cm, and the height of the fixing support is within the range of 4-5 cm.

Preferably, the base is adhered with an EVA non-slip mat, and the thickness of the base is 0.3 mm.

Preferably, the base is connected with the fixing support through a lock catch in interference fit.

The beneficial effects of the utility model, a prevent that centrifugal bottle weighs device that holds of empting is provided, the fixed subassembly of setting is firm reliable and do not influence the reading, its simple structure, convenient operation, low cost to be difficult for empting in the use, can be used to in the chemistry experiment room.

Description of reference numerals: 1-base. 2-fixing support, 3-EVA anti-slip mat and 4-lock catch.

Detailed Description

As shown in figures 1-2, the utility model relates to a prevent that centrifugal flask weighs holding device of empting, including fixed bolster 2, the support main part is standard cylinder chamber, and the centrifugal flask can be placed in the cavity for fixed centrifugal flask bottom circular cone structure avoids taking place to empty the phenomenon in the centrifugal flask use.

The device also comprises a round base 1 with a slightly larger diameter, and the round base 1 and the fixed support 2 are connected into a whole to play a role in fixing.

Further, the diameter of the base 1 is about 5cm, and the diameter of the fixing support 2 is about 3 cm. In this manner, the device can remain stable for use when dispensing by centrifuge bottle weighing.

Further, the base 1 is bonded with a layer of EVA non-slip mat 3 with the thickness of 0.3cm, so as to prevent the device from sliding and falling in the using process.

Further, be connected through interference fit's hasp 4 between fixed bolster 2 and the base 1 to fixed bolster 2 can change the size of a dimension as required for fix other laboratory glassware.

Further, because the height of the cylindrical cavity of the fixing support 2 is too high, materials are wasted, reading accuracy of the centrifuge bottle is influenced, the height of the centrifuge bottle is too low, gravity center of the centrifuge bottle is easy to fall, and the range of 4-5 cm is suitable for selecting the height.

Will during the use the utility model discloses place on the electronic balance tray, peel, take off centrifugal bottle lid and put in 2 bottoms of fixed bolster, place the centrifugal bottle in cylindrical cavity again, can stabilize the centrifugal bottle, carry out subsequent interpolation medicine reading work.

The utility model provides a prevent that centrifugal bottle weighs holding device of empting, its simple structure, low cost, convenient operation to be difficult for empting in the use, can be used to in the chemistry experiment room.

The present invention is not intended to be limited to the specific embodiments described herein, and any modifications, equivalent substitutions, improvements, etc. that can be made by one skilled in the art within the spirit and principle of the inventive concept are intended to be included within the scope of the present invention.
