Abstract
The invention provides a volumetric flask bracket. The bracket comprises a side plate, a bottom plate and a positioning plate, wherein the bottom plate and the positioning plate are fixed on the side plate; the positioning plate is divided into an upper layer and a lower layer; the side position of the upper positioning plate is provided with an L-shaped opening; the lower positioning plate is provided with a regular through hole; and the through hole corresponds to the L-shaped opening. The invention can be convenient for an operator to carry out batch volume constancy and move a volumetric flask when the volumetric flask is fixed and has the advantages of test speed improvement, time saving, simple structure and practicability.
Description
Technical field
The present invention relates to a kind of support of fixed capacity bottle, especially fixedly the support of the following small size volumetric flask of 250mL.
Background technology
Volumetric flask is measuring bottle again; It is a precision measuring instrument that is used for preparing certain volume, certain amount of substance concentration solution; Be one of container the most frequently used in chemical analysis and the test experience chamber, in analytical test, generally standard substance, test sample extract carried out constant volume with volumetric flask.
Volumetric flask is shaped as thin neck, pyriform, Flat bottom container, has ground glass bottle stopper or plastic plug, and its neck is carved with an annular graticule, to show the volume number of liquid constant volume to this moment.Its thin neck is convenient to constant volume, flatly then is convenient to move put on the table.The specification of the present volumetric flask of volumetric flask is generally 5mL, 10mL, 25mL, 50mL, 100mL, 200mL, 250mL, 500mL, 1000mL, 2000mL, 5000mL.The small size volumetric flask of 5mL to 250mL specification is the series that each laboratory purposes is the widest at present, quantity is maximum; Because small size volumetric flask body is higher; Flat less, in test operation, slow, mobile inconvenience of constant volume speed and occurrence of tilting phenomenon in batches easily.
China has implemented " detecting and calibration laboratory capability Approval criterion " (CNAS-CL01:2006) in 2006; This criterion is equal to ISO/IEC 17025:2005; Criterion 5.3.1 bar " is used to the laboratory facility that detects and/or calibrate; include but not limited to the energy, illumination and environmental condition, should help the correct enforcement that detects and/or calibrate ".Criterion has not only stipulated to provide corresponding laboratory facility to promote the correct enforcement that detects and/or calibrate, and requires simultaneously testing result is carried out uncertainty evaluation, guarantees that it accurately and reliably.At present; According to CNAS-CL01:2006 or ISO/IEC 17025:2005; China has strengthened each test experience chamber the input of laboratory equipment, constantly various instruments is upgraded improved and complete equipment and measure; FAO (Food and Agriculture Organization of the United Nation) (FAO)/international food code committee of joint institution of The World Health Organization (WHO) (CAC) is according to the requirement of ISO/IEC 17025 simultaneously; Formulated " the assessment guide rule of uncertainty as a result ", guide rule points out that uncertainty is mainly derived from sample extraction, sample treatment and analysis three phases as a result, and sample treatment and analysis are up to 63% to the contribution of uncertainty.
With volumetric flask to the sample solution in each stage and/or standard liquid carry out constant volume be detect and analytic process in one of most crucial steps; If constant volume mistake or inaccurate whole testing result and the actual conditions of will causing are not inconsistent even mistake; Therefore select accurate volumetric flask, be equipped with corresponding volumetric flask support, not only can batch process volumetric flask constant volume; Accelerate test speed; Saving time, improve the testing result degree of accuracy and accuracy, also is the effective solution of avoiding test incidents such as volumetric flask is toppled over, sequence error.
At present, there is not the fixedly support of small size volumetric flask of research and development in this field.
Summary of the invention
Technical problem to be solved by this invention provides a kind of fixedly small size volumetric flask, is convenient in batches volumetric flask constant volume, accelerates test speed, saves time, and avoids that volumetric flask is toppled over, the volumetric flask support of constant volume sequence error.
Technical scheme provided by the invention is: a kind of volumetric flask support; This support comprises side plate and is fixed on base plate and the location-plate on the side plate; Said location-plate is divided into upper and lower two-layer; The side edge of upper strata location-plate has " L " shape mouth, is provided with the through hole of rule in lower floor's location-plate, and through hole is corresponding with " L " shape mouth.
The dual-side of said upper strata location-plate all has " L " opening.
Said side plate, base plate and location-plate are plastic plate, plank or glass plate.
Of the present invention have a following advantage: the present invention can be in the fixed capacity bottle, and the handled easily person is constant volume and mobile volumetric flask in batches, accelerates test speed, saves time, and is simple in structure, practicality.
Description of drawings
Fig. 1 is the structural representation of volumetric flask support of the present invention.
Fig. 2 is the structural representation of the upper strata location-plate of volumetric flask support of the present invention.
Wherein, 1-through hole, 2-" L " shape mouth, 3-upper strata location-plate, 4-base plate, 5-lower floor location-plate, 6-side plate.
The specific embodiment
Below in conjunction with accompanying drawing, come further to illustrate the present invention through the detailed description of the specific embodiment, but be not limitation of the present invention, only make example description.
Volumetric flask support, this support comprise side plate 6 and are fixed on base plate 4 and the location-plate on the side plate 6.Location-plate is divided into upper and lower two-layer, and the dual-side place of upper strata location-plate 3 all has " L " shape mouth 2, is provided with regular circular through hole 1 in lower floor's location-plate 5, and through hole 1 is corresponding with " L " shape mouth 2.Hole size is confirmed according to the flat specification of volumetric flask.Side plate 6, base plate 4 and location-plate are plastic plate, plank or glass plate.Interval height between base plate 4 and location-plate three-lane road and plate is according to the specification of volumetric flask and highly definite, and during use, volumetric flask is put into this support from " L " shape mouth 2, and pass lower floor's location-plate 5 and is placed on the base plate 4 at the bottle end.
