Component Identification (Figure 3)
(10) Condenser Extension. The condenser extension is a replaceable glassware fitting that
connects the condenser and distribution head.
(11)
Condenser. The RapidStill II is equipped with a combined Allihn and spiral condenser
for efficient recovery of the distillate.
(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.
