Detailed function of Components
1. Manifold Assembly. The hood features a molded, 6" diameter exhaust connection sized to
allow for a minimum of static pressure loss through the hood structure and one that still can
provide a good transport velocity through the exhaust system.
2. Condenser Head System
essential part of the digestion process. The vapors from the boiling digestion medium are
condensed on the condenser heads and returned to the medium continually washing the sides
of the beakers in the process.
3. Heater System. Each 350 watt adjustable spring loaded heater provides an even distribution
of heat through the use of coiled heater wires embedded in a ceramic material.
4. Variable Heat Control Switch. Provides variable input from 20-100% of capacity to each
heater.
5. Elevation Control Knob. Adjusts beakers positions.

INSTALLATION
Installation
Model 30001, 115 Volt, 50/60 Hz. 18.3 amps, is complete except no power cord is
supplied on the unit. The customer must provide wiring to the main power switch in accordance
with local electrical codes. The unit is supplied with 12 - 600 ml beakers. The unit is also
equipped with individual infinite control switches with pilot lights for each heater and a main
ON/OFF switch. The condensers are Type 304 stainless steel. A 3/8" NPT valve is provided to
control water flow through condensers.
Model 30002, 6 unit, 230 Volt, 50/60 Hz, 9.11 amps, is complete except no power cord is
supplied on this unit. The customer must provide wiring to main power switch in accordance
with local electrical codes. The unit is supplied with 12 - 600 ml beakers. The unit is also
equipped with 12 each individual infinite control switches with pilot lights for each heater and a
main ON/OFF switch. The condensers are Type 304 stainless steel. A 3/8" NPT valve is
provided to control water flow through condensers.
Installation Instructions
Location
Choose a location in the laboratory which has a convenient electrical outlet of the voltage
required, a cold water supply of 3/8" NPT and drain facilities of at least 1/2" NPT.
Connections
Connect the 3/8" NPT water inlet valve, located on the upper left side of the unit to your
cold water supply. This valve regulates the flow of water through the condenser heads.
Connect the 3/8" NPT water outlet located on the upper right side of the unit to an open
drain area of at least 1/2" in size. An open drain connection will allow the operator to make a
visual check of water flow through the condenser head system.
After the proper electrical connections are made, the unit is now ready for routine
operation.
Start-Up and Check-Out
All the heater control switches should be turned on to insure proper performance.

NORMAL OPERATION
Normal Operation
The following section provides a general outline of steps necessary to perform a routine
digestion on the Labconco Crude Fiber Digestor. Actual test methods, sample preparation,
solvent choices, etc., are determined by official methods of the A.O.A.C. and should be referred
to in all cases.
• Turn on cold water supply, check visual flow at the drain area. The heater and water
flow rates may be adjusted to vary the reflux rates according to the operator’s preference.
• Prepare samples per standard method for the product under examination
• Place required quantity of sample in the beaker.
• Place digestion medium of proper type and quantity into beaker.
• Place beaker on the heaters and while firmly holding knob turn 1/4 turn to the left, and
slowly let beaker rise to condenser head. DO NOT
position against condenser head.
• Turn the main power switch, located on the right side, to the “ON” position. Controls on
the panel independently regulate one 350 watt heater. The pilot lights indicate heater
“ON” cycle.
let go of knob until beaker is in
• Follow A.O.A.C. method and procedure for determination of fiber content
