Product introduction

Laboratory PTFE watch glass is a laboratory vessel made of polytetrafluoroethylene (PTFE). It is usually round in shape, pure white in appearance, slightly concave in the middle, similar to an evaporating dish. It can be placed on an evaporating dish or beaker to prevent dust and other impurities from falling in and keep the substances in the laboratory vessel pure.

Product features

(1) Good temperature resistance: can be used in the temperature range of -200℃ to +250℃.

(2) Strong corrosion resistance: can withstand strong acids, strong alkalis, aqua regia and various organic solvents.

(3) Low pollution: low blank value of metal elements, not easy to contaminate experimental samples.

(4) Excellent insulation: good insulation performance, not affected by environment and frequency.

(5) Aging and radiation resistance: has good atmospheric aging resistance and radiation resistance.

(6) Good self-lubrication: small friction coefficient, smooth operation.

(7) Non-stick surface: not easy to adhere to substances, easy to clean.

(8) Non-toxic and harmless: physiologically inert, no harm to human body and environment.

Product applications

(1) As a lid: Cover the evaporating dish or beaker to prevent impurities from falling in.

(2) For evaporation: Increase the surface area of the liquid at room temperature or low temperature to assist evaporation.

(3) Hold reagents: Temporarily store solid or liquid reagents, especially corrosive ones.

(4) Hold test paper: Used to hold pH test paper, etc. to prevent the table from being corroded.
