Definitions
Some terms come up in these operating instructions, which
require some clarification.
Glass assemblies:
A: with diagonal condensers, for standard distillations
V: with vertical condenser, for standard distillations, 17 cm
less place requirement than glass assembly A
C: with cold traps for dry ice, for distilling solvents with low
boiling points
S: with vertical condenser and reflux capability
CR: with cold traps and reflux capability, for distilling solvents
with low boiling points
E: with descending condenser without reflux capability, ide-
al for solutions, with tendency to foaming
GLAS
P GLAS (abbreviated PLG) is a unique protective
layer for glass components. It offers improved mechanical
rupture resistance and increases protection against broken
glass. It also makes sure that the sample is not lost in the
receiving flask, if the flask is damaged.
