Round Bottom Laboratory Porcelain Capsules: 125 ml Capacity and 98 mm Diameter
Laboratory porcelain is highly resistant to high temperatures but not resistant to put on fire or direct flame, so they are generally used with laboratory drying ovens. However, it can also be used with a Bunsen burner with the precaution of placing an insulated wire mesh between the flame and the container. The evaporation capsule is used for the separation of solutions by evaporation through the application of heat and, reaching higher temperatures, is a support for carbonizing or melting substances and chemical compounds.
It is used by jewellery and silverware professionals, metallurgical and ceramic companies, pharmacies, hotels, kitchens and laboratories in general.
The porcelain is made of clay, quartz and feldspar (3AL2O3 . 2SiO2) and meets the parameters of the highest working demand for its high quality, good chemistry and heat resistance.
High softening temperature, which allows working up to 1150 °C / 2,102 °F (ca. 1,150 °C)
High mechanical resistance
Low longitudinal thermal expansion
