Disposable solid-liquid dual-purpose laboratory weighing scoop

Technical Field

The utility model belongs to the technical field of experimental apparatus, especially, relate to a disposable solid-liquid dual-purpose laboratory weighing scoop.

Background

Currently, the closest prior art in the industry: in physical or chemical experiments, a weighing scoop and a suction pipe are indispensable experimental tools, most of weighing scoops used for weighing solid samples are made of stainless steel or plastic materials at present, and although the weighing scoop can be repeatedly used, the samples are easily polluted due to unclean cleaning or corrosion of a scoop body; when the sample amount is large, a large amount of manpower and time are consumed for cleaning a large amount of weighing scoops; when weighing a liquid sample, a disposable PE suction pipe or a rubber head glass suction pipe is needed, and the rubber head glass suction pipe is difficult to clean and easy to have residues. And when weighing solid and liquid samples, the two need to be switched back and forth, causing weighing work inefficiency.

In summary, the problems of the prior art are as follows:

(1) when the existing weighing scoop is repeatedly used, the sample is easily polluted due to unclean cleaning or corrosion of the scoop body.

(2) When the sample size is great, need wash a large amount of weighing spoon, lead to wasting a large amount of manpower and time.

(3) When weighing a liquid sample, a multi-purpose disposable PE suction pipe or a rubber head glass suction pipe is needed, and the rubber head glass suction pipe is difficult to clean and is very easy to have residues. And when weighing the sample of solid and liquid, weighing spoon and pipette need switch round trip, cause and weigh the work inefficiency.

The difficulty of solving the technical problems is as follows:

1. the utility model is made of disposable PE material, has low cost, can be recovered, does not need to be cleaned, and completely avoids the problem that the weighing spoon and the glass suction tube can not be cleaned completely or the spoon body is corroded to pollute the sample;

2. because the utility model does not need to be cleaned, the symmetrical measuring spoon does not need to be cleaned by personnel, and the manpower is easily liberated;

3. at weighing a large amount of solid sample and liquid sample in-process, need weighing spoon and pipette round trip switch, lead to weighing inefficiency, and the utility model discloses have the effect of weighing and inhaling the volume, solid and liquid sample all can use, have avoided the switching of weighing spoon and pipette, have promoted greatly and have weighed efficiency.

The significance of solving the technical problems is as follows:

1. the pollution problem is a common problem which puzzles experimenters in the experimental process, the accuracy of a detection result is seriously influenced, the weighing and the pretreatment of a sample are high-incidence stages of pollution introduction, and in order to prevent the pollution introduction, the experimental process has strict requirements on the use of vessels and instruments and the experimental operation. The utility model is a disposable PE weighing scoop, which thoroughly solves the problem that the common stainless steel weighing scoop is polluted because of improper cleaning or corrosion after long-term use, and reduces the probability of sample pollution to the lowest;

2. the utility model is used as a disposable PE weighing scoop, has low cost and one-time use, does not need to be cleaned by personnel, and liberates manpower;

3. use the utility model discloses when weighing the sample, avoided the switching of weighing spoon and pipette, simplified and weighed the operation, improved and weighed efficiency.

SUMMERY OF THE UTILITY MODEL

To the problem that prior art exists, the utility model provides a disposable solid-liquid dual-purpose laboratory weighing scoop.

The utility model discloses a realize like this, a disposable solid-liquid dual-purpose laboratory weighing scoop is provided with the spoon handle, and spoon handle left end butt fusion has a spoon head, spoon handle right-hand member and gasbag butt fusion, gasbag and straw butt fusion.

The utility model discloses a spoon is multi-purpose, both can weigh solid sample, also can absorb liquid sample, avoids the two to make a round trip to switch in the title appearance in-process, has promoted the efficiency of title appearance by a wide margin.

Furthermore, the straw is provided with scale marks. Through being provided with the scale mark, can directly perceived the volume of absorbing the sample approximate.

Furthermore, the spoon head, the spoon handle, the air bag and the straw are recyclable PE bodies. The weighing scoop is integrally made of recyclable PE material, so that the weighing scoop is environment-friendly and low in cost; the disposable use can avoid the waste of labor and time in a laboratory caused by cleaning a large number of weighing scoops; meanwhile, the problem of sample pollution caused by unclean cleaning or spoon body corrosion can be avoided.
