Description & Specifications
Porcelain Buchner Funnel
Technical Specification
Funnels, Glazed porcelain Buchner funnel for fast filtration. Buchner,
Porcelain Buchner funnel with fixed perforated plate, glazed both inside
and outside with the exception of the top rim. Due to its inherent
properties, Porcelain Labware is widely used in the chemistry
laboratory.
It has excellent resistance to all reagents except hydrofluoric acid,
and is highly resistant to thermal shock while having a very low
coefficient of expansion.
The average coefficient of expansion from 20° to 200°C is 3.56 x 10-5 gradually increasing to 4.69 x 10-5 at 1000°C.
To prevent thermal stress cracks on porcelain ware do not exceed a heating/cooling rate of 200°C per hour.
To prolong the life of porcelain products : Avoid contact of
heated ware with a cold surface. Carefully inspect labware prior to each
use and do not use any product that appears defective. To prevent
thermal stress cracks on porcelain ware do not exceed a heating/cooling
rate of 200°C per hour.
