Abstract
The utility model belongs to the field of experimental glass apparatuses, and in particular relates to a safe measuring cylinder for measuring experimental reagents when an experiment is performed in a laboratory. The measuring cylinder is characterized in that an internal measuring cylinder body and an internal measuring cylinder base are integrated, the internal measuring cylinder base is fixed in the middle of the bottom of an external cylinder, an anti-escaping plug is arranged above an internal measuring cylinder, the upper surface of the anti-escaping plug is provided with a feeding port, and the space between the external cylinder and the internal measuring cylinder can store a transfer pipette and a rubber-head drip tube. The internal measuring cylinder comprises the measuring cylinder base, the anti-escaping plug and a discharging port, and the base which is arranged at the bottom of the internal measuring cylinder body is connected with the bottom of the external cylinder. The anti-escaping plug is arranged above the internal measuring cylinder, and the middle of the anti-escaping plug is provided with a feeding port. The problem that taken reagents overflow out of the outer wall of the measuring cylinder is resolved by means of the double cylinder layer design, and the safety problem of taking volatile reagents is effectively resolved by means of the anti-escaping plug. Material-taking tools including the transfer pipette and the rubber-head drip tube are properly placed, the damage due to the messing storage of the material-taking tools is avoided, and the service life of a transfer pipette frame and a rubber-head drip tube frame is prolonged.
Description
Technical field
The utility model belongs to experiment glass apparatus field, specifically relates to a kind of safe graduated cylinder that is used for measuring experiment reagent when experimentizing in the laboratory.
Background technology
Carry out all kinds of chemical classes experiments in the laboratory, must measure the required liquid reagent of experiment, wherein, graduated cylinder, beaker, transfer pipet, glue head dropper, burette holder etc. all are the instruments of measuring experiment reagent.But at present, in the laboratory, do not have a kind of safe graduated cylinder and can measure experiment reagent, experiment reagent often all is a poisonous and harmful, inflammable and explosive, have corrosivity, common graduated cylinder is measured above the outer wall that can flow to graduated cylinder in the reagent process, holds when measuring discharging, can contact the experiment reagent above the graduated cylinder outer wall, experimenter's skin is worked the mischief; Need use glue head dropper to drip and transfer pipet when measuring solvent, transfer pipet and glue head dropper are cylindrical, be placed on and be easy on the desktop tumble, finish using and occupy the glue head dropper of measuring solution and transfer pipet and be put back into and be easy to above the pipet stand pipet stand is polluted, pipet stand is produced corrosion, shorten the serviceable life of pipet stand or glue head Dropper stand; When measuring experiment reagent with common graduated cylinder, some reagent volatility is very strong, and the reagent of pouring in the graduated cylinder evaporate into air at once, and experimenter's health is caused certain harm.These problems have had a strong impact on the effect of experiment, and to experimenter's skin, health causes serious harm.
Therefore, design a kind of graduated cylinder that can in experiment, measure reagent solution safely, the problem that formal inventor is faced for the deficiency that overcomes above-mentioned technology.
Summary of the invention
At the deficiencies in the prior art; the purpose of this utility model provides a kind of at the graduated cylinder that can measure experiment reagent safely; it is simple in structure; easy to operate; can safety measure experiment reagent; succinctly deposit reagent and take instrument, particularly protected experimental work person's personal safety, improve the serviceable life of pipet stand and glue head Dropper stand.
The technical scheme that its technical matters that solves the utility model adopts is: the safe graduated cylinder of a kind of experiment, the interior graduated cylinder that comprises urceolus and be arranged on the inside, it is characterized in that: graduated cylinder cylindrical shell and interior graduated cylinder base are one in described, interior graduated cylinder base is fixed in the middle of the outer tube bottom, there is anti-ease plug interior graduated cylinder top, anti-ease face beyond the Great Wall has charge door, and transfer pipet and glue head dropper can be deposited in the space between urceolus and the interior graduated cylinder.
Graduated cylinder is by the graduated cylinder base in described, and anti-ease plug, discharging opening composition, base are positioned at graduated cylinder cylindrical shell bottom and are connected with outer tube bottom, and anti-ease plug is positioned at above the graduated cylinder, in the middle of the anti-ease plug charge door is arranged.
Graduated cylinder cylindrical shell, base, urceolus and bottom are that suprasil material or high-boron-silicon glass are made in described, and anti-ease plug is made for silastic material.
The beneficial effects of the utility model are:
1, by the design of bitubular layer, ensured that taking reagent overflows to the danger of graduated cylinder outer wall;
2, by the design of anti-ease plug, effectively avoided taking the volatile reagent safety problem;
3, get material instrument transfer pipet and glue head dropper is properly placed, avoid getting the material instrument and disorderly deposit damage, guaranteed the serviceable life of pipet stand and glue head Dropper stand.
Description of drawings
Fig. 1 is the utility model synoptic diagram.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values drop on application appended claims institute restricted portion equally.
In Fig. 1, a kind of experiment graduated cylinder comprises urceolus 9 and is seamless link with outer tube bottom 10, and base 6 usefulness bonding way place outer tube bottom 10 centres, and glue head dropper 7 and transfer pipet 8 place in the space 5 between urceolus 9 and the interior graduated cylinder cylindrical shell 4.Interior graduated cylinder is made up of base 6, cylindrical shell 4, anti-ease plug 3 and discharging opening 2, base 6 is connected to cylindrical shell 4 low sides and is seamless link, there is the scale mark of expression volume on cylindrical shell 4 surfaces, anti-ease plug 3 is clogged in cylindrical shell 4 tops, discharging opening 2 is positioned at the tip edge of cylindrical shell 4, be standing shape and certain slit arranged, in the middle of the anti-ease plug 3 charge door 1 is arranged with anti-ease plug 3.Space 5 provides the position and provides assembling position for glue head dropper 7 and the transfer pipet 8 that speckles with reagent for glue head dropper 7 and transfer pipet 8.
When the utility model uses, draw experiment reagent with glue head dropper 7, join in the cylindrical shell 4 by charge door 1, when waiting to measure liquor capacity near the amount of taking, using transfer pipet 8 instead measures experiment reagent and continues to join in the cylindrical shell 4 by charge door 1, up to reaching requirement, the hand-held urceolus 9 of experimenter is with Fig. 1 integral inclination, make cylindrical shell 4 interior experiment reagents slowly flow out corresponding containers by discharging opening 2, finish, hungry area head dropper 7 and transfer pipet 8 inboards and remained on surface experiment reagent are cleaned up, after drying, glue head dropper 7 and transfer pipet 8 can be played back to respectively on glue head Dropper stand or the pipet stand.And the utility model patent has avoid contacting poisonous and harmful reagent in measuring the reagent process, avoid contacting the poisonous and harmful substance that volatile reagent can send, avoid the reagent instrument of taking to leave about damage, effectively prolonged advantages such as glue head Dropper stand and pipet stand serviceable life.
