Purpose of the Spe-ed ™SFE Basic 1.1
The Spe-ed™SFE Basic allows an analyst to perform supercritical fluid extractions simply
and efficiently. Developed in conjunction with the USDA, the Spe-ed™SFE Basic has
achieved simple sophistication in design and use. With its flexibility of both dynamic
(continuous flow) and static (where supercritical CO2 is pressurized in a sealed extraction
vessel for a specific period of time) modes, the Spe-ed™SFE Basic offers precise, repeatable
performances for a variety of laboratory procedures including, but not limited to:
• Extracting pesticides and PAHs from soil samples
• Extracting antibiotics and steroids from veterinary products
• Extracting natural products
• Extracting monomers from polymeric compounds
• Extracting fat from food products

manufacturer to determine whether vessels used can withstand the pressures and
temperatures that the SFE Basic is capable of delivering. Do not operate the Spe-
ed™SFE Basic beyond the MAWP (Maximum Allowable Working Pressure) of the
vessel. No warranties are given on the extraction vessels beyond those provided
by the manufacturers.

Caution The Spe-ed™SFE Basic was designed to use CO2 or CO2
containing organic solvent modifiers only. The use of any other fluid will render
all warranties void.
Caution This instrument is not intended for use with Nitrous Oxide, or with
corrosive compounds such as ammonia or sulfur hexafluoride, which can form an
explosive mixture with organic compounds.

Compressed Air Line
The Spe-ed™SFE Basic requires a compressed air line (or cylinder) with a minimum
delivered pressure of 100 psig (6.9 BAR) and capacity of 6.2 actual cfm (cubic ft./min.) or
48 standard cfm. The compressor should be set to turn on at 95 psig (6.6 BAR) and turn off
at 125 psig (8.6 BAR)
Electricity
The Spe-ed™SFE Basic will need a dedicated electrical outlet of 120VAC, 50/60Hz,
20amps (P/N 99351) or 240VAC, 50/60Hz, 10amps (P/N 99350).
Vial Venting
Accessory connections and tubing are available for venting into collection vials and flow
meter hookup. Any extractions using hazardous materials should be done under a fume hood
or the flow meter outlet should have tubing venting into a fume hood.
Pressure Relief Connections
A 3/8” female NPT fitting can be connected to a CO2 safely head outlet. This connection
may be used to direct emergency venting to a remote location in the event of a rupture disc
failure.

Cylinder Safety Requirement
Provisions should be made for clamping the CO2 cylinder to either a permanent table edge or
wall by using the appropriate cylinder bracket.

OvervieworFeatures 1.5
The Spe-ed™SFE Basic is capable of pressures up to 10,000 psig and oven temperature up to
240° C. Within this range of pressures and temperatures the analyst can accomplish a wide
range of extractions.
Several unique features are incorporated into the Spe-ed™SFE Basic that overcome many of
the problems researchers currently encounter with other designs. For example, one of the
most troublesome problems encountered is the clogging of fixed flow restrictors.
The Spe-ed™SFE Basic system eliminates clogging by employing a patented, variable
micro- metering valve interface system. This non-clogging metering system has the capacity
to process even the most fat-laden samples as well as polymer, pharmaceutical and
environmental samples.
Another fixed flow restrictor problem is sample contamination carry over into the transfer
lines due to the inaccessibility of cleaning fixed restrictors.
Understanding the need to correct this frequent problem, the Spe-ed™SFE Basic’s valve and
transfer line systems were designed for simultaneous solvent flushing and with the provision
for an operator to collect any residue for further analysis. As a result, no contamination can
occur between extractions.
Additional features of the Spe-ed™SFE Basic include:
1. Control of flow rates between 0-5.5 LPM of expanded CO2 gas.
2. Increased liquid CO2 pressures of up to 10,000 psig (690 BAR), 10-100 times greater
than currently available.
3. Operation in either static and/or dynamic modes.

REQUIRED UTILITIES SECTION 2
LiquidCarbonDioxide(CO2) 2.1
Most analyses will require Instrument grade CO2 or CO2 passed through a CO2 clean-up
column. (See the “Accessories” section of this manual.) A dip/eductor tube will be required
in the CO2 cylinder.
Caution The CO2 cylinder must contain a dip/eductor tube to ensure that
liquid CO2 is delivered to the pump module.
Note The CO2 tank shut-off valve controlling the carbon dioxide must be opened before
the system can be pressurized.
Note Refer to section 3 for operating instructions with a refrigerated cooling bath
(RCB).
Note Prior to operating Spe-ed™RCB, it is important to pressurize the SFE Basic to a
minimum CO2 Pressure. Open the CO2 tank and then turn on RCB. When RCB
reaches the desired cooling temperature, operating pressure may be increased to
its optimum setting.
Electricity 2.2
The Spe-ed™SFE Basic will operate with a dedicated electrical circuit on either a 120VAC,
50/60Hz, 20amps (P/N 99351) or 240VAC, 50/60Hz, 10amps (P/N 99350) line.
For use outside the United States, the power cord will require an appropriate adaptor. Your
dealer will be able to assist you in the necessary adaptation for your specific power supply.
Caution High Voltage exists within enclosure. Allow access to qualified
personal only.
Compressed Air 2.3
Compressed air is necessary to drive the pump. Maximum air pressure should be 125 psig
(8.6 BAR) the minimum is 100 psig (6.9 BAR). The air supply may be obtained from an air
compressor or from air cylinders, although it is recommended that an air compressor be used.
If it is necessary to use gas cylinders, use a technical grade of air.
Recirculating Coolant 2.4
Recirculating Coolant is required by the pump for CO2 pressurization. The recirculating
coolant should be maintained at a controlled temperature of 0°C.
