Spoon for weighing samples

Abstract

The invention provides a spoon for weighing samples. The spoon for weighing samples has the advantages of simple structure and operation convenience, and improves accuracy and convenience of sampling. The spoon comprises a spoon body and spoon head; the spoon body comprises a sleeve 1 and a sleeve 2, and the sleeve 2 is connected in the sleeve 1 in a telescopic connection; the spoon head comprises a spoon mouth and a spoon handle which are integrated into one body, the surface of the sleeve 1 is provided with a storage groove, the spoon handle is arranged in the storage groove, the spoon handle is a telescopic rod, double sides of the storage groove are provided with positioning grooves, double sides of the spoon handle are provided with positioning blocks, and the positioning blocks are arranged in the positioning grooves adaptively. The spoon head and the spoon handle employ an inserted connection form, in order to facilitate connection of spoon heads of different specifications with wide adaptability; the spoon handle is connected in the storage groove and is fixed by the positioning blocks and the positioning grooves, at the same time the spoon handle is the telescopic rod with conveniently adjusted length, and connection reliability of the spoon head is further improved by band fixation. The spoon for weighing samples has the advantages of processing convenience and reduced cost.

Description

technical field [0001] The present invention relates to the improvement of a symmetrical spoon. Background technique [0002] For routine sample and drug determination in the laboratory, weighing paper is usually used for direct measurement, and then the weighing paper is added to a wide-mouthed reagent bottle or reagent tube. However, for some narrow-necked bottles, long bottles and even long glass tubes, when a small amount of sample addition is required, the traditional weighing paper sample addition method will face large caliber, insufficient length, difficulty in sending samples, and loss during sample delivery. and other issues have the most direct impact on the measurement results. At present, there are many specifications of sampling spoons when weighing samples. Many laboratories usually use a variety of sampling spoons, such as long handle, short handle, wide head and other specifications. But for the sample spoon, there is no corresponding product yet. In most...

But for the sample spoon, there is no corresponding product

In most cases, it is made temporarily and discarded after use. The next time you encounter the same weighing, you will face the same problem. Therefore, it is necessary to design a sampling spoon that can meet the various needs of the laboratory.
