Abstract
The present invention belongs to a laboratory appliance, and relates to an anti-overflow crucible, which comprises a crucible bottom, a crucible wall and a crucible opening, wherein the waist portion or bottom portion of the crucible outwardly and upwardly extends to form the waist support or the bottom support, the waist support port or the bottom support port is greater than the crucible opening, and the height of the waist support wall or the bottom support wall is 0.5-1.5 cm. According to the present invention, a sample requiring melting and a fluxing agent are added to the crucible, the sample is subjected to high temperature melting, the melting liquid overflows in the waist support or the bottom support if a small amount of the melting liquid overflows so as not to cause the sample solution loss, and the melting sample is easily subjected to wash-out so as to ensure the accuracy of the experiment.
Description
Technical field
The invention belongs to use for laboratory utensil, relate to a kind of crucible, specifically a kind of Anti-overflow crucible.
Background technology
In laboratory, we often use crucible high-temperature digestion sample, and at high temperature, fused solution often has a small amount of spilling, affects the accuracy of experimental data.
Summary of the invention
The invention provides the Anti-overflow crucible that a kind of structure is simple, practical.
The present invention realizes with following technical scheme:
1, an Anti-overflow crucible, comprise (1) at the bottom of crucible, sidewall of crucible (2), mouth of pot (3), crucible waist outwards upwards extends to form waist holder; Waist holder mouth (4) is greater than mouth of pot (3); Waist holder wall (5) high 0.5 ~ 1.5cm.Add in crucible by the sample needing to melt and flux, high-temperature digestion sample, if liquation has a small amount of spilling, then can overflow in waist holder, can not cause the loss of sample liquid, ensure that the accuracy of experiment.
2, an Anti-overflow crucible, comprise (1) at the bottom of crucible, sidewall of crucible (2), mouth of pot (3), crucible bottom outwards upwards extends to form collet; Collet mouth (7) is greater than mouth of pot (3); Collet wall (6) high 0.5 ~ 1.5cm.Add in crucible by the sample needing to melt and flux, high-temperature digestion sample, if liquation has a small amount of spilling, then can overflow in collet, can not cause the loss of sample liquid, ensure that the accuracy of experiment.
The invention has the beneficial effects as follows: advantage of the present invention is that device is simple, practical; The spilling of liquation when effectively preventing crucible from melting sample, the wall simultaneously arranging collet and waist holder is high between 0.5 ~ 1.5cm, ensure that easily washing out of molten sample, ensure that the accuracy of experiment.
Accompanying drawing explanation
Fig. 1 is the crucible structure schematic diagram having waist holder in the present invention.
Fig. 2 is the crucible structure schematic diagram having collet in the present invention.
In Fig. 1 ~ Fig. 2, (1), sidewall of crucible (2), mouth of pot (3), Yao Tuokou (4), Yao Tuobi (5), collet wall (6), collet mouth (7) at the bottom of crucible.
