Product introduction

Laboratory PTFE beaker cover refers to the cover made of polytetrafluoroethylene (PTFE) material, which is used to cover the laboratory PTFE beaker. It is generally round in shape, mostly white or off-white in color, and its size matches the corresponding PTFE beaker. It has different diameter specifications to accommodate beakers of various capacities, such as 50mL, 100mL, 250mL, etc.

Product features

(1) Chemical corrosion resistance: does not react with strong acids, strong alkalis, strong oxidants and organic solvents.

(2) High and low temperature resistance: can be used for a long time at -180℃ to 260℃, and can withstand high temperatures of 300℃ for a short time.

(3) Low friction and self-lubrication: low friction coefficient, self-lubricating, non-sticky, easy to clean.

(4) Good sealing: fits tightly with the beaker to prevent leakage and volatilization.

(5) Good insulation: can effectively isolate current.

Product applications

(1) Chemical experiments: used in various chemical reactions to prevent reagent volatilization and external impurities from entering, ensuring the purity and stability of the reaction system.

(2) Sample storage: when storing samples, it plays a sealing role to prevent samples from being contaminated or deteriorating.

(3) Heating operation: when heating the beaker, it reduces heat loss and liquid splashing, improving experimental safety and accuracy.

(4) Digestion experiment: in some experiments that require digestion, the new cooling reflux cover can be used to achieve acid vapor condensation reflux, improving experimental efficiency.
