film used to temporarily seal aqueous solutions.
A desiccant (drying agent) used in desiccators which is often treated
with cobalt chloride which will turn from blue to pink as the desiccant
stationary phase in chromatographic separations
that is used to as a thin film on glass joints to prevent them from
seizing and to seal them in reduced pressure distillations. It may
also be used to seal the lids of desiccators.
of glass that is made by heating powdered glass below its melting
point so that the particles stick to each other. The result is a material
which will allow liquids to pass through it but it will retain solid
material. Sintered glass can be used to make filters as well as the
support for the stationary phase in chromatography columns.
solution of precisely known concentration used in volumetric analysis.
volumetric analysis to detrmine the exact concentration of a standard
of moles involved in a reaction in accordance with the balanced equation.
phase in a chromatographic separation.
