(12) Ventilation Valve. The ventilation valve prevents the distillate from
being aspirated back into the condenser after the distillation is
completed. If the valve sticks closed, remove it and wash out any
material accumulated inside the valve.
(13) Safety Screen. The plastic safety screen is designed to protect the
operator. The screen should always be in the closed position during
operation of the RapidStill II.
(14) Boiler Viewing Slot. Looking through this slot the operator can easily
inspect the water level in the boiler. Low and high water level marks
are on the boiler flask to ease the inspection and addition operations.
(15) Distillate Outlet Tube. This tube carries distillate from the condenser
to the solution in the receiving flask. The bulb of the tube must be
totally immersed in the receiving solution.
(16) Distillation Timer Switch. The infinitely adjustable 0-15 minute
timer controls the dispensing of steam into the digestion tube. It is
interlocked to function only when the boiler heater is on. As an
additional safety measure, NaOH cannot be dispensed into the
digestion tube when the timer is in operation.
(17) Spillage Tray. The spillage tray is designed to collect spilled reagents
and overflow. The tray is removable and may be cleaned with
ordinary soap and water.
