Product introduction

PTFE volumetric flask is a measuring device made of polytetrafluoroethylene (PTFE) material for accurately measuring and preparing a specific volume of solution. The bottle body is usually pear-shaped or cylindrical, and the bottleneck is the part connecting the bottle body and the bottle mouth, which is relatively slender. Bottle stopper: It is generally also made of polytetrafluoroethylene and fits tightly with the bottle mouth.

Product features

(1) Strong corrosion resistance: It can withstand the erosion of various strong acids, strong alkalis, strong oxidants and organic solvents.

(2) Wide temperature adaptability: It can be used for a long time in the temperature range of -200℃ to 250℃.

(3) Low adsorption: The surface is smooth and has little adsorption on most substances, ensuring the accurate concentration of the solution.

(4) High accuracy: The scale is accurately calibrated and can accurately measure and prepare the solution.

(5) Good sealing: The matching bottle stopper can effectively prevent the solution from volatilizing and impurities from entering.

(6) Good chemical compatibility: It does not react with a variety of chemical substances, ensuring the stability of the solution properties.
