Description
Technical field
Experimental instrument field is the utility model is related to, more particularly to a kind of porcelain crucible.
Background technology
Porcelain crucible is the important component of chemical apparatuses, and porcelain crucible is a kind of chemical laboratory articles for use, main component：Oxygen
Change aluminium (45-55%), silica.Highest can heat-resisting 1200 degrees centigrade high temperature.Melted suitable for acidic materials such as K2S2O7
Melt sample.It fundamentally cannot be used and flux melting is made with alkaline matters such as NaOH, Na2O2, Na2CO3, in order to avoid corrosion porcelain crucible.Porcelain
Crucible can not contact with hydrofluoric acid.Porcelain crucible, which is generally available dilute HCl and boils cleaning, to be washed.
Porcelain crucible can be divided into by species：Mesospore crucible, low wall crucible, high wall crucible, plain crucible, volatilization crucible, tight crucible, Luo Jia
Crucible, double-deck crucible, Gooch crucible, pore crucible, Infrared Carbon-sulphur crucible, free wxpansion coefficient crucible etc..
Ceramics have water imbibition.So in order to reduce error, after should strictly drying crucible before use on assay balance
Weigh.Analyte is filtered with ashless filter paper sometimes, puts filter paper into crucible together；This filter paper is complete in high temperature environments
Decompose, do not interfere with result.After high-temperature process, by crucible and institute it is tolerant in special drier dry cooling, then claim again
Amount.It is whole to be gripped with clean crucible tongs.
Porcelain crucible is usually used in checking " residue on ignition " project in Pharmaceutical Analysis, and its operating method is generally as follows：
1st, take crucible to be placed in Muffle furnace, lid is tiltedly covered on crucible, it is blazing about 30~60 minutes through 700~800 DEG C,
200 DEG C are cooled to, is closed the lid in dislocation drier, letting cool to room temperature (typically about needs 60 minutes), accurately weighed crucible weight.
Under these conditions blazing about 30 minutes again, take out, put in drier, let cool, weigh；Until constant weight (after blazing twice in succession
Weight differential 0.3 below ㎎ weight), it is standby.
2nd, defined weight under 1.0~2.0g of test sample or respectively the medicine item is taken, is put in the crucible of ignition to constant weight, essence
It is close weighed.
The 3rd, the crucible for filling test sample put on electric furnace or gas lamp to slowly calcination (avoids test sample from expanding suddenly and escaped
Go out), blazing to test sample, all charing is in black, does not smoke clogging, lets cool to room temperature.This process should be grasped in vent cabinet
Make.
4th, unless otherwise specified, 0.5~1.0ml of sulfuric acid is added dropwise, carbide is all moistened, continues in electric furnace or gas lamp
On be heated to sulfuric acid vapor and eliminate, white cigarette is wholly absent (operation should be carried out in vent cabinet above), and crucible is put in Muffle furnace, lid
Son is tiltedly placed on crucible, blazing is ashed completely to test sample at 700~800 DEG C.
5th, rise from " take out crucible, slightly cold a moment " by operating method 4, operate in accordance with the law, until constant weight (after blazing twice in succession
Weight differential 0.3 below ㎎ weight).
For crucible in podzolic process, its lid is tiltedly to be placed on crucible it can be seen from " residue on ignition " operating method,
And in actual mechanical process, due to extreme temperatures, often gripped using crucible tongs, mobile crucible, it is easy to slide crucible lid
Fall, cause crucible cover broken or pollution, influence that its is accurately weighed, and crucible constant weight requires the high (weight after blazing twice in succession
Measure difference 0.3 below ㎎ weight), thus it is guaranteed that crucible cover steadily tiltedly be placed on the error that can avoid weighing on crucible.
Utility model content
Purpose to be solved in the utility model is to provide a kind of porcelain crucible, ensured using crucible tongs gripping, mobile earthenware
Lid is not slid in order to avoid causing crucible cover broken or polluting during crucible, and it is accurately weighed to influence its.
To achieve the above object, the utility model uses following technical scheme：
A kind of porcelain crucible, including porcelain crucible body, the porcelain crucible body are positive cone structure, in the porcelain crucible body
Support beam is horizontally installed with, the support beam pinpoints the one end for the post that is articulated and connected, and the other end of the connecting pole, which is fixed, to be connected
It is connected to the pot cover to match with the porcelain crucible body.
The porcelain crucible sheet of positive cone is easily put surely compared to the porcelain crucible of existing inverted conical shape, is using the instruments such as crucible tongs
During mobile porcelain crucible, when placing, it is not easy to topple over so that the experimental drug in porcelain crucible releases；Support beam top crown hinge connects
One end of connecting pole, connecting pole can rotate around Zhi Dingdian pin joints, coordinate the side wall of porcelain crucible body will be fixed on connecting pole
Pot cover be tiltedly placed on porcelain crucible body, and in mobile porcelain crucible body, pot cover, which is not fallen off, to be caused to break into pieces or pollutes
The accurately weighed of porcelain crucible is influenceed, improves the precision of experiment.
Preferably, fixed point is hinged with fixed seat in the support beam, the fixed seat is detachably connected by screw thread
One end of connecting pole.
Preferably, the pin joint of the support beam and the fixed seat is the midpoint of support beam.
Preferably, the porcelain crucible body is provided with the breach to match with connecting pole along side.
Preferably, it is provided with handle at the top of the pot cover.
Beneficial effect is：The utility model is easy to use, ingenious in design, gripped using crucible tongs, mobile crucible when cover
Son is not fallen off in order to avoid causing crucible cover broken or polluting, and is effectively reduced crucible weighting error, is protected laboratory apparatus
Meanwhile improve the precision of experiment.
