Abstract

The utility model belongs to the chemical apparatus and equipment field, and especially relates to a weighing disk. The weighing disk comprises a box body (1). The box body (1) comprises a side wall (2) and a flat bottom portion (3). An inner side of the side wall (2) is of a smooth arc shape. The inner side of the side wall (2) is provided with grooves (4). The grooves (4) are connected with a top end of the side wall (2) and the flat bottom portion (3). The number of the grooves (4) is two. The two grooves (4) are symmetrically arranged. The weighing disk has the advantages of simple structure and convenient operation, is helpful for weighing medicines of accurate mass, and can prevent a scale pan of a scale from being eroded.

Description

A kind of weighing disk

Technical field

The utility model belongs to the chemical apparatuses apparatus field, particularly a kind of weighing disk.

Background technology

What the accurate weighing of analytical chemistry was the most frequently used is electrooptical balance or the electronic balance that has the stainless steel pan of a steelyard; No matter be direct weighing method or successively decrease weighing method; Following problem occurs easily: (1) is in experiment; Need put a pan paper on the pan of a steelyard, paper is too little then can not to cover pan of a steelyard, and paper then is prone to run into the small beaker that is placed with drying agent too greatly.(2) some corrosion-prone chemical reagent of weighing if desired are difficult for cleaning in case spill, and corrode pan of a steelyard easily.(3) to operating unskilled student, when using direct weighing method, particle fell into pan of a steelyard easily when the solid of the amount of weighing up was taken; When successively decreasing weighing method, measuring cup is easy to overturn, and these errors all can make pan of a steelyard corroded.

The utility model content

The purpose of the utility model is the deficiency that overcomes prior art, and a kind of weighing disk is provided, and this weighing disk not only helps to take by weighing the medicine of exact mass, and can prevent that the pan of a steelyard of balance from being corroded.

The scheme that the utility model solve the technical problem is: a kind of weighing disk, comprise box body, and box body is made up of sidewall and flat bottom, and it is smooth circular-arc that the inboard of sidewall is.

During weighing, the weighing disk of cleaning oven dry is placed electronic balance, the zeroing back can guarantee that treating that the medicine of weighing is added to flat bottom medicine is positioned at the centre position of pan of a steelyard all the time, improves the accuracy of weighing; It is smooth circular-arc that the inboard of sidewall is, and conveniently pours the medicine after the weighing into beaker, uses deionized water drip washing inboard wall of cartridge subsequently, and the deionized water after the drip washing is also poured beaker into along the inboard of sidewall, further improves the accuracy of weighing.Each use the afterwash oven dry, can reuse, the effect of play environmental protection, low consumption, not corroding pan of a steelyard also is difficult for making measuring cup to overturn or the reagent particle is fallen on the pan of a steelyard, thereby makes weighing more convenient, prolongs the serviceable life of balance.

As further technical scheme, the inboard of said sidewall is provided with groove, and groove connects the top and the flat bottom of sidewall, and the quantity of groove is 2, and 2 grooves are symmetrical set.

The inboard of sidewall is provided with groove; Groove connects the top and the flat bottom of sidewall, conveniently medicine is got into beaker along groove, owing to reduced the contact area of medicine and box body; Can reduce the probability that medicine is bonded at inboard wall of cartridge, make the medicine that takes by weighing all get into beaker; Article 2, groove is symmetrical set, and can guarantee the balance of box body quality, reduces weighing error.

In sum, the utlity model has simple in structure, easy to operate advantage, not only help to take by weighing the medicine of exact mass, and can prevent that the pan of a steelyard of balance from being corroded.
