Abstract
The utility model discloses an analytical balance is a transparent box with simple and easy application of sample supplementary weighing device, its main part, and a round hole is offered respectively to the last nowel face of transparent box, and relative both sides face case face is penetrating form, sets up a sleeve pipe in the transparent box nowel face round hole, and the sleeve pipe bottom links firmly a base, and base diameter is lighter than nowel face round hole aperture. The utility model discloses the sample loss that container wall and ground position wall built -up caused has been avoided, the influence of hanging on the in -process weighing funnel when having a small amount of sample the weighing accuracy has also been avoided weighing, place in the round hole on box upper portion behind the application of sample funnel that lets in long and narrow container, can be with the powder, particulate solids or liquid under the condition of not being rebuffed accurate add long and narrow container inside, make direct dosage call sample thief or medicine enable, and compare to weigh in the use and shift after the sample thief is called to paper to the method of container, can reduce operation steps, efficiency has been promoted, the weighing error has also been reduced simultaneously.
Description
Technical field
The present invention relates to sampling meausring apparatus.
Background technology
Laboratory widely uses analytical balance and carries out sample and medicine weighing, thus carrying out sample pre-treatments.The difference of kind and requirement of experiment per sample in weighing process, weighing mode mainly takes method of addition and Subtraction method two kinds.
When using method of addition to weigh powder or graininess sample or medicine, if use such as containers such as 50ml ground conical flask, 100ml rub oral examination tube or bottom is rounded and cervical region is long and narrow test tube, micro-wave diminishing pots, because sample or medicine wall built-up need to be avoided, and its problem cannot being kept upright in weighing room, can not be weighed to dosage direct in container by analytical balance, often use the method that pan paper transfers in container after weighing, but the situation that still cannot avoid wall built-up occurs, add experimental procedure simultaneously, increase the impact of personal error.
Summary of the invention
The present invention provides the auxiliary meausring apparatus of a kind of more efficiency, to realize can directly using the special container such as long and narrow test tube, micro-wave diminishing pot to weigh sample or medicine, and reduces experimental error.
For realizing the object of the invention, this auxiliary meausring apparatus is characterized in that its main body is a transparent cabinet, a circular hole is offered in the upper nowel face of described transparent cabinet respectively, relative case face, two sides be penetrating shape, in the circular hole of transparent cabinet nowel face, sleeve is set, sleeve bottom is connected a base, and described base diameter is less than circular hole aperture, nowel face.
Described box shape is the square bodily form or cuboid.
The technological progress that the present invention obtains:
The present invention utilizes the circular hole on transparent material casing in order to support funnel, the special container such as long and narrow test tube, micro-wave diminishing pot are placed in the circular hole under casing, by filler neck part, sample or medicine are sent directly into internal tank, avoid sample or medicine loss that chamber wall and ground position wall built-up cause, thus it also avoid the impact of weighing accuracy when hanging with a small amount of sample in weighing process on weighing funnel；The long and narrow container being circular for bottom (fills in ground digestive tube as 100ml has, part brand micro-wave diminishing pot etc.), the sleeve pipe of long and narrow its external diameter can be used more than, due to the connected base of sleeve bottom, long and narrow container can make long and narrow container be in firm erectility after inserting sleeve pipe, thus after placing, in the circular hole on casing top, the application of sample funnel passing into long and narrow container, can by powder, granular solids or liquid accurately add long and narrow internal tank when not being rebuffed, make direct dosage weigh sample or medicine is possibly realized, and compared to the method using pan paper to be transferred to container after weighing sample, decrease operating procedure, both efficiency had been improved, also reduce weighing error simultaneously.

Detailed description of the invention
Embodiment 1: as shown in Figure 1, this simple and easy application of sample auxiliary its main body of meausring apparatus being suitable to analytical balance use of the present invention is a profile is square, cuboid or cylindrical transparent cabinet 2, a circular hole 3,1 is offered respectively in the upper and lower case face of transparent cabinet 2, relative case face, two sides be penetrating shape, in transparent cabinet nowel face circular hole 1, sleeve 4 is set, be connected bottom sleeve pipe 4 base 5, and the diameter of base 5 is less than the aperture of circular hole 1 on nowel face.As shown in Figure 2, when long and narrow containers such as using class such as round bottom micro-wave diminishing pot 8 weighs sample or medicine, first transparent cabinet 2 is put in the weighing room of analytical balance 6, the circular hole 1 that transparent cabinet 2 bottom center offers is buckled in weighing plate outer ring and is not in contact with it, micro-wave diminishing pot 8 is inserted in the sleeve pipe 4 being connected on the base 3, reset after being placed on the weighing plate of balance 6 again, weighing funnel 7 is put into transparent cabinet 2 center hole 3 above, the cervical region making weighing funnel 7 inserts in micro-wave diminishing pot 8, and (observing whether balance reading changes) is not contacted with micro-wave diminishing pot 8, after installing is good, quantitative sample can be carried out according to method of addition or medicine adds micro-wave diminishing pot 8.Same sample or medicine, without wiping funnel 7, after changing sample or medicine, need before weighing to take off funnel 7 filter paper wiped clean.Should be noted should select the transparent cabinet 2 of supporting height to weigh when the long and narrow containers such as round bottom micro-wave diminishing pot 8 are weighed sample or medicine.
Embodiment 2: as shown in Figure 3, the present embodiment difference from Example 1 is, this its main body of auxiliary meausring apparatus is a profile is square, cuboid or cylindrical transparent cabinet 2, offer a circular hole 3,1 respectively in the upper and lower case face of transparent cabinet 2, relative case face, two sides is penetrating shape.When such as 50ml ground conical flask 9 weighs sample or medicine to use class, transparent cabinet 2 is put in the weighing room of analytical balance 6, the circular hole 1 that transparent cabinet 2 bottom center offers is buckled in weighing plate outer ring and is not in contact with it, resetting after ground conical flask 9 being placed on weighing plate, all the other operating procedures are identical with embodiment 1.
Claims (2)
1. an auxiliary meausring apparatus, it is characterized in that its main body is a transparent cabinet, a circular hole is offered in the upper nowel face of described transparent cabinet respectively, relative case face, two sides be penetrating shape, in the circular hole of transparent cabinet nowel face, sleeve is set, sleeve bottom is connected a base, and described base diameter is less than circular hole aperture, nowel face.
2. auxiliary meausring apparatus according to claim 1, it is characterised in that described box shape is the square bodily form or cuboid.
