Section 1
Introduction
Bio-Scale Mini cartridges have a patent-pending
double-wall design that provides extra durability and
allows easy, reliable runs with aqueous buffers
commonly used for protein purification. The
polypropylene luer fittings and internal sealing
surfaces ensure leak-free operation at pressures up
to 45 psi. Bio-Scale Mini cartridges are convenient,
disposable, and supplied ready for use. They are
easy to use and prepacked for fast, reproducible
chromatographic separations. Cartridges are available for a variety of chromatographic techniques,
including desalting, ion exchange, affinity, and
mixed-mode chromatography. The design of
Bio-Scale Mini cartridges offers:
• Ready-to-go convenience; simply equilibrate
the cartridge in the buffer of choice
• Luer fittings for convenient connection to any
chromatography system or directly to a
Luer-Lok syringe

Bio-Scale Mini Macro-Prep High Q and S and
Macro-Prep DEAE cartridges are packed with
Macro-Prep
®
ion exchange media. These media are
based on hydrophilic spherical polymeric beads
designed for the purification of proteins, nucleic
acids, viruses, plasmids, and other macromolecules.
Macro-Prep beads are designed to provide medium
capacity, low backpressure, and high productivity.
Detailed product information is given in Tables 1
and 2. See Ordering Information for a listing of the
complete Bio-Scale Mini cartridge product line.

Section 2
Connecting to Bio-Rad’s
Low-Pressure
Chromatography
Instruments
Bio-Scale Mini cartridges are ideal for use with
Bio-Rad's BioLogic
™
LP chromatography system,
Econo
™
gradient pump, the patented* Model EP-1
Econo
™
pump, and all low-pressure chromatography instruments. Bio-Scale Mini cartridges can be
conveniently connected directly to the system using
the luer fittings on the cartridge.
1. Install 1.6 mm inner diameter (ID) tubing in the
pumphead. Adjust the platen pressure screw
(on pumphead) – using a screwdriver or coin,
turn the screw counterclockwise as far as it will
go, then turn clockwise three full turns.
