polypropylene tubing that extends directly
into the bottle so that no metal parts
come in contact with the charge. The tank
itself, its valves and pressure gages are
made of stainless steel. These parts are
well suited for use with hydrogen. All of
these valves have stainless stems, TFE
packing and replaceable PCTFE seats
to ensure positive, leak-proof control in
quantitative procedures. A smaller, one-
liter stainless tank (A16CA2) is available
for semimicro operations in which small
amounts of gas must be measured. The
regular valves are easily transferred to
this smaller tank.
A 6-ft pressure hose is furnished with
each apparatus for filling the hydrogen
tank from a commercial gas cylinder. This
can be attached easily to any gas pressure
regulator or tank valve system.
Pressure Tested Bottles
Reaction bottles for these hydrogena-
tors are offered in several sizes as listed
in the table below. All are made of boro-
silicate glass and individually pressure
tested to twice their specified maximum
working pressure. Several of these bottles
can be furnished with a tough outer fiber-
glass coating. These coated bottles are no
stronger than the plain ones, but the fiber-
glass envelope will usually retain any bro-
ken glass and prevent the loss of valuable
reactants in case of accidental breakage.
When considering the listed bottle
sizes it must be remembered that in most
catalytic procedures the reaction bottle
is filled only about half full to leave suf-
ficient space for effective mixing.
