0.4 - 2 liter LowRider Working Volume

PR-SUB (Perfusion-Ready-Single-Use-Bioreactor)

Complete your in-house assembled perfusion systems integrating the “LowRider” PR-SUB and save hood time. Bottom broth outlet for a Levitronix pump used for circulation the broth through the HFF. The LowRider-3 is designed to complete most 0.4 - 2 liter Working Volume perfusion system.

Left and middle photo – the LowRider-3 PR-SUB, the unique broth outlet at bottom via a hose and a first aseptic connector, retentate return to the SUB through a second aseptic connector on a hose and back into the LowRider-3. The right photo shows two different size Levitronix pumps (as to requirement) and one installed on the MST.

Features for the configurable LowRider-3 size PR-SUB

  • First class rigid mono component PolyCarbonate components
  • Any colour on head-plate (light blue is standard)
  • Dimension: OD 137 x 270 mm CellVessel = 3.2 liter Vessel Volume
  • Magnetic-Bottom-Drive (MBD) for impeller integrated with Aero magnet motor
    A. Radial agitation Elephant ear impeller, OD 60 mm, 3 blades, 45 degrees, CW rotation down flow, 55 mm from the bottom = traditional design
    B. Axial agitation Elephant ear impeller, OD 60 mm, 3 blades, 45 degrees, CW rotation down flow, 55 mm from the bottom and stator system = lower RPM and reduced foam production

Multiple head plate ports

  • 1 x PG 13.5 port pre-installed with PolarWell or VisiWell for non-invasive DO RUS insert
  • 1 x PG 13.5 port pre-installed with OneFerm pH Single-Use-Sensor with K9 connector
  • 3 x free / extra sensor ports PG 13.5
  • 1 x L-sparger macro or your preferred sparger
  • 1 x dip tube for retentate return with 500 mm 10/14 hose + your preferred connector (AseptiQuick AQS17006 3/8")
  • 6 x small inner diameter 900 mm long closed weldable hoses for various inlet and outlets on head plate
  • 1 x bottom harvest with swabable valve on short hose
  • 1 x exhaust with 2 x OD 60 mm sterile filters

Bottom side port = “Low-Rider” barb broth outlet + 200 mm long 9.5/14.3 hose + your preferred connector (AseptiQuick AQS 17006 3/8") or the Levitronix Single-use-Pump.

Seen from left a set of PR-SUBs and aseptic connectors. Center photo shows a beautiful low outlet in particular useful for Levitronix pumps. A set of Low-Rider-2 PR-SUBs ready for installment of Hollow-Fibre-Filter modules. 

Needed or nice to have re-usable accessories:

  • Re-Usable electrical heating jacket (pn 42966) to be bolted on the MST = very safe solution
  • Re-Usable elastic electrical heating blanket (dim 75 x 350 mm) = traditional setup
  • Magnetic-Stirrer-Table (MST) like the Compact model (p/n: 42500-C-8-x) = any servo motor
  • SUB support plate for MST (p/n: 42521-15) = use with electrical heating blanket
  • If needed - converter kit for servo motor (p/n: 42000 series)
  • If needed - Sterile-Filter-Heater (p/n: 42900 series)
  • Accessories to be found here - Accessory Products

The LowRider-3 mounted on the MST to be driven by any servo motor. Very stable and safe solution with no heavy servo motor on the low weight PR-SUB. Centre photo MST mounted with the black Kollmorgen motor used by many BioStat PCS. Left photo shows a great solution combining the LowRider-3 with the Levitronix pump.
