High temperature resistant sample bottle is a container designed for high-temperature environments, which can maintain structural stability and chemical inertness under harsh temperature conditions. It is widely used in high-temperature experiments, sample storage, chemical reactions, and industrial analysis.
Common materials and properties
Borosilicate glass: It has good heat resistance, usually able to withstand high temperatures up to about 500 ° C, and is easy to clean. It has good chemical stability and can resist the erosion of most chemical reagents, but its texture is fragile.
Polytetrafluoroethylene: It can work stably in the temperature range of -200 ℃~+250 ℃, has strong chemical resistance, and can withstand almost all chemical solvents.
Soluble polytetrafluoroethylene (PFA): It is a fluorinated plastic with good transparency and a temperature range of -200 ℃ to+260 ℃. It has low dissolution and precipitation, is not easy to hang on the wall, and is easy to clean. It is commonly used for storing standard substances, highly corrosive, and high-purity reagents.
Specifications and Capacity
There are various capacity specifications, including 5ml, 10ml, 15ml, 20ml, 30ml, 50ml, 100ml, 250ml, 500ml, 1L, etc., which can be selected according to the actual sample size requirements.
The shapes include wide mouthed bottles, narrow mouthed bottles, etc. Wide mouthed bottles are convenient for taking solid samples, while narrow mouthed bottles are suitable for storing liquid samples and reducing volatilization.
Application scenarios
Laboratory research: Used for high-temperature chemical reactions, sample pretreatment, trace analysis and other experiments. When using a mixture of hydrofluoric acid and nitric acid to digest samples, high-temperature resistant sample bottles made of polytetrafluoroethylene or PFA material can be selected.
Industrial production: In industries such as chemical, pharmaceutical, and food, borosilicate glass sample bottles are used to store high-temperature raw materials, intermediate products, or finished products. For example, in the pharmaceutical industry, some drugs that require high-temperature sterilization storage can be stored in borosilicate glass sample bottles.
Environmental monitoring: plays a role in collecting and storing water samples, soil samples, etc. in high-temperature environments to ensure that the samples are not affected by temperature during transportation and analysis.
