FLOCELL
Flocells™ are used for the continuous processing of large volumes of sample material. The liquid is
pumped into the Flocell™ through a carefully designed opening so that all of the sample passes
through the cavitation field and receives maximum, uniform sonication. The annulus and orifice sizes
are variable to accommodate differing viscosity and flow rate. Flocells™ are available that can
process material at rates of 10 gallons per minute. Materials of construction vary with applications.
Transparent Polycarbonate Model (Part # 800A)
This model permits observation of the sonication process. The material of the body tube is resistant
to most dilute acids and bases, oils, aliphatic hydrocarbons, ethers and alcohols. It may be attacked
by strong alkalis, aromatic or halogenated hydrocarbons, or low molecular weight aldehydes. DO
NOT EXCEED 50 psig PRESSURE or operate at full power on the Sonicator
amplitude setting, as
this will damage the Flocell .
Stainless Steel Model (Part # 800B)
The material of the body tube is resistant to most dilute acids and bases, oils, aliphatic hydrocarbons,
ethers and alcohols. Strong acids can attack it. DO NOT EXCEED 100 psig PRESSURE or operate
at full power on the Sonicator
amplitude setting.
The following information applies to both Models 800A & 800B.
1. Three ¼” NPT hose fittings and three ¼” NPT plugs are supplied.
2. Do not use the two body ports as both inlet and outlet.
3. Flow must be directed through the orifice. Select the appropriate size orifice and install it into
the Flocell with a # -014 size O-ring in the orifice holder.
4. Assemble the orifice with the stepped side away from the holder, projecting through the
knurled orifice retainer ring. Hand tighten retainer ring onto orifice holder.
5. Assemble a -026 size O-ring onto the holder and wet the O-ring and the mating surface on
the inside of the Flocell body.
6. Use care in assembling the holder to the body to prevent stripping the first threads or cutting
the -026 size O-ring.
7. Similarly, wet the -220 size O-ring in the other end of the body and the mating surface of the
disruptor horn and fit the body over the disruptor horn.
8. Screw the Flocell body around the disruptor horn until the horn contacts the oriface plate and
then back it off 3 turns.
9. The Flocell should not be tightened on the horn or it will dampen the ultrasonic
vibrations.
10. Adjust the sonication annulus by screwing the holder in or out the appropriate distance from
the radiating face on the tip of the horn.
11. Install inlet fittings into orifice holder and outlet and overflow fittings into Flocell body.
12. Connect soft plastic inlet and outlet tubing to the fittings provided, with valves as required.
13. Valves should be installed at the outer ends of the tubing to minimize the weight hanging
from the horn.
14. Test the completed assembly for leakage before pressurizing.
Flow can be in either direction if only one inlet is used. It may be more advantageous to direct flow
upwards through the orifice holder and out through the body fitting. Flow must be from the body
toward the orifice holder if two inlets are used.
Orifice retainer and holder are stainless steel and have very fine threads shipped with a light film of
machine oil to prevent galling. If the oil film is removed with the use of solvents or any other means,
apply molybdenum disulfide, powdered Teflon, graphite or other appropriate lubricant.
