General Description
The Labconco RapidStill I is designed expressly for rapid, semi-automatic steam
distillation from sulfuric acid digest prepared from nitrogen-bearing materials
such as feeds, grains, soils, plant tissue, water effluent, organic waste food
products, etc. Sample digestions are accomplished utilizing either Labconco’s
Digestion Apparatus or Rapid Digestor units.
Performance
Your Labconco RapidStill I has been designed to accept digested samples up to
4 ml (maximum) equivalent of concentrated acid, and is capable of giving
reproducible results in ranges as low as 10 micrograms (gamma) #1% nitrogen.
The RapidStill I may also be utilized for other steam distillations that DO NOT
exceed the volume limitations of the units mixing chamber (approximately 50 to
55 ml).

Component Identification
(1) Power Switch Switches power to the Heater. When ideal Heat Control
setting is achieved, use this switch to turn Heater ON and OFF.
(2) Heat Control The electric immersion heater provides fast, efficient heat.
Steam generation starts very rapidly from a cold start. Control input to the
heater and steam output by adjusting this knob.
(3) Fill Valve The Fill Valve is opened only when filling Boiling Flask. Use
distilled water from the Water Bottle to keep water level in the steam
reservoir approximately 2/3 full during distillation.
(4) Aspirator Stopcock The unit has a built-in glass aspirator to purge spent
samples after determination. The water used for cooling of this condenser
is also used for aspirating. A twist of the Aspirator Stopcock draws the
sample and rinse water down the drain.
(5) Sample Addition Funnel Use this funnel to transfer digested sample to
the Mixing Chamber.
(6) Sample Addition Stopcock The upper PTFE stopcock that allows for
the addition of samples or pH controlling solutions.
(7) Mixing Chamber The inner bulb in the lower portion of the still where
the sample is mixed with appropriate solutions during the distillation.
(8) Cooling Water Connections Note the two barbed fittings extending
through the back of the housing. Connect the “IN” fitting to a cold water
source and the “OUT” fitting to a drain.
(9) Condenser Cold water flows through the outer wall of the tall column to
condense steam.
(10) Boiling Flask The round flask reservoir which contains distilled water to
be heated during the distillation.
(11) Flask Shelf Shelf is adjustable in height. Positioning the flask is
important to maintain relationship between the condenser outlet and liquid
level in the Receiving Flask.
(12) Heater Heater is energized when there is sufficient water in the Boiling
Flask. Heater may be unplugged from the housing if required.
(13) Water Bottle Use distilled water only in the still. Water Bottle is
squeezed to introduce water to the Boing Flask via the Fill Valve.

(2) Starting with the large U-clamp, place both the large and small U-clamps
around the glassware and through the brackets. Gently tighten the clamp
nuts so that the glassware is firmly held to the Base Housing.
(3) Carefully attach the condensing water tubing to the glass barb fittings. Do
not add clamps or any lubricant (other than water) to these connections.
Turn Base Housing upright.
(4) Locate the RapidStill I where there is convenient 115 volt outlet and
accessibility to cold tap water and drain.

(5) Obtain several lengths of flexible plastic or silicone tubing (3/8" ID x 1/16"
wall). Tubing IS NOT furnished with the unit and may be obtained from
laboratory supply dealers. Connect tubing from the rear of the housing to a
drain or sink for effluent. Connect tubing for the inlet from the rear of the
housing to a cold water source (<25oC) with fine flow control through a
valve or faucet. Two pinch clamps have been provided. Check for leaks.
(6) Keep power OFF. Insert the heater element into the Boiling Flask and press
the stopper into the Flask opening firmly. Heater should not be in contact
with any of the glass. NOTE: This must be sealed for distillation. Plug the
Heater into the Base Housing connector.
