Description

Laboratory plug scale test tube fixing device

Technical Field

The utility model relates to a laboratory apparatus stopper scale test tube fixing device belongs to test tube fixing device technical field.

Background

In chemical analysis laboratories, cuvettes with stoppered graduations generally require volumetric operations. Without special fixtures, it is difficult and time consuming to operate and difficult to grasp the accuracy of the sizing operation. The fixing device of the present test tube with plug scales is mainly a test tube rack. There are some problems with the fixed utensil stopper scale test tube of test-tube rack, and the test-tube rack hole number is limited, when handling the bulk sample, can't satisfy the experiment needs, and the test-tube rack generally all is three layer construction, and the number of piles is many, the observation of solution colour in the test tube of not being convenient for.

In chemical analysis laboratories, there are many experiments that require a water bath to heat a tube with a plug scale of a sample solution in a water bath, and three problems are usually encountered when heating. One problem is that when utensil stopper scale test tube is directly placed in the hole of water-bath, because of the diameter and the size of utensil stopper scale test tube are more, the hole of water-bath is difficult to satisfy the utensil stopper scale test tube of different specifications, and the utensil stopper scale test tube appears slipping easily, smashes, the excessive circumstances such as solution, causes the inaccurate or experimental failure of experimental result. Another problem is that when placing the cuffed test tube in a large beaker or other carrying container, friction, squeezing and toppling of the cuffed test tube can be caused between the cuffed test tube, which can also cause inaccurate experimental results or failure of the experiment. And when will have stopper scale test tube to place in containers such as beaker, the container inner wall has the closure effect to having stopper scale test tube, hinders inside steam gets into the beaker, and utensil stopper scale test tube distributes unevenly in the beaker, leads to having the solution in the stopper scale test tube can not fully thermally equivalent. The third problem is that if the test tube with the plug scales is placed in the test tube rack, the test tube rack is placed in a water bath to be heated, and for a large number of samples, the samples need to be heated in batches, and because the heating time is asynchronous, the experiment can be carried out to bring large errors.

After the test tube with the plug scale is used, the test tube needs to be dried. The existing fixing device for the test tube with the plug scale does not consider the drying function of the test tube with the plug scale after use.

The existing fixing device for the test tube with the plug scale lacks a white background plate for comparing color depth, and a white background needs to be found additionally for comparison in an experiment.

SUMMERY OF THE UTILITY MODEL

For solving the defect that prior art exists, the utility model aims at providing a convenient to use makes the laboratory apparatus that the test tube distributes evenly fill in scale test tube fixing device.

The technical scheme of the utility model is that: the utility model provides a laboratory apparatus stopper scale test tube fixing device, is linked together through the through-hole on the orifice plate between base and the frame including fixing the frame on the base, and the frame top is equipped with the supporting network that is used for preventing the test tube from empting, the mesh of supporting network is relative with the through-hole of bottom, and the through-hole bottom is equipped with the waterlogging caused by excessive rainfall box, waterlogging caused by excessive rainfall box and the cooperation of the base slip pull formula.

And a white background plate is arranged on the side part of the frame.

The side part of the frame is provided with a side plate which is vertical to the background plate.

And a handle a is arranged on the draining box.

The top of the frame is provided with a handle b.

The aperture of the through hole is smaller than the caliber of the test tube.

The base and the frame are both square.

The utility model has the advantages that: the base and the frame are square, and are suitable for most of water tank type constant-temperature water baths; the test tube is matched and fixed with the through hole at the bottom through the supporting net at the top, so that the fixing effect is good, and an operator can conveniently perform experiment operation; the test tubes are all fixed in the device, and when the test tubes are heated in a water bath, water is uniformly distributed around the test tubes with the plug scales, so that the consistency of the heating effect of the test tubes with the plug scales is ensured; after the experiment is finished, the water draining device can be used as a drying device for a test tube with a plug scale, the opening of the test tube is downward, and the residual water in the test tube flows into a bottom draining board along the through hole to be collected, so that the water drops are prevented from flowing out and wetting the experiment table surface; the design has the background board, is convenient for observe the change of solution colour in having stopper scale test tube at any time.
