Laboratory equipment glassware that can be used to heat chemicals
The burner is a glass instrument that can be used to heat chemical substances. The materials used are generally strict. Hard 95 materials or GG-17 high-silicon borosilicate glass should be used.
Flasks generally refer to beakers, conical (triangular) flasks, three-neck (one-neck, two-neck, four-neck) round-bottom flasks, flat-bottom flasks, test tubes, condensers (spherical, serpentine, straight, air, etc.), distillation heads, Fractionation head, fractionation column, rectification column.
The measuring device is a glass product engraved with a relatively accurate scale and used for capacity measurement. The material can be made of 75 materials. The quality evaluation standard is the measurement accuracy and measurement accuracy.
Measuring instruments generally refer to measuring buckets, measuring cups, burettes (acid, alkali), pipettes (or graduated straws), volumetric flasks, thermometers, hydrometers, sugar meters, hygrometers, etc.
The container is a glass product that contains chemical substances. Generally, the material is thick. Strictly speaking, its material should also be mainly soft sodium-alkali chemical glass frit. However, most manufacturers even choose ordinary glass. The characteristic is that the wall is thicker. Containers generally refer to various narrow-mouthed bottles, wide-mouthed bottles, lower-mouthed bottles, drop bottles and various glass tanks.
In addition, there are various funnels (spherical, pear-shaped, dripping, triangular, etc.), petri dishes, dryers, drying towers, drying tubes, washing bottles, weighing bottles (boxes), mortars, glass tubes, sand core filter, etc.
There are also a small number of optical glass and quartz glass instruments such as colorimeters, colorimetric tubes, magnifying lenses, microscope heads, etc.
The specification of glass instruments is mainly based on volume and length. The same type of instrument is very finely divided from small to large, but due to the level of laboratory use, the volume is between 1ml and 10000ml, and the length is generally between 5 cm and 10000 cm. The division of its specifications and models adopts the principle of halving.
