Beakers
Multisizer 4 Smart Technology Beakers (ST Beakers) are available in 100 mL, 200 mL, and 400 mL
sizes.
The unique design of ST Beakers optimizes particle suspension. A spherical interior interrupted by
a raised cone creates an unstable area below the stirrer that provides uniform particle distribution.
The base of each ST Beaker is designed to fit a built-in guide on the sample platform (see Sample
Platform, page 1-9). When the platform is raised to the analysis position, the guide positions the
beaker for optimum fluid circulation, ensuring that the aperture tube is approximately 1/8 inch
from the beaker wall. The raised base of the beaker maximizes the volume of fluid the Analyzer is
able to extract before drawing air through the aperture orifice.
The combination of ST Beakers and the built-in guide allows the Multisizer 4 to deliver consistent,
optimal results not possible to obtain with beakers designed by other manufacturers.
NOTE
If you are using a beaker produced by another manufacturer, it may be necessary to manually adjust
the position of the beaker on the platform. Variations in the position of the beaker relative to the
aperture tube, electrode, and stirrer during analysis runs can produce inconsistent results.
Accuvette® STs
Beckman Coulter Accuvette® STs are disposable and include a secure lid to prevent spills and
contamination. Rounded corners in the interior encourage re-suspension of settled particles.
Use a 20 mL Accuvette® ST in combination with an aperture tube 100 µm or smaller.
The base of each Beckman Coulter Accuvette® ST is designed to fit a built-in guide on the sample
platform (see Sample Platform, page 1-9). When the platform is raised to the analysis position, the
guide positions the Accuvette® ST for optimum results and maximizes the volume of fluid the
Analyzer is able to extract before drawing air through the aperture orifice.
The combination of Accuvette® STs and the built-in guide allows the Multisizer 4 to deliver
consistent, optimal results not possible to obtain with sample vials designed by other
manufacturers.
Calibrators
Beckman Coulter provides calibrator beads in sizes ranging from 2 µm to 90 µm. For information on
calibrating the aperture tube and selecting the appropriate calibrator size, see Calibrating the
Aperture, page 3-10.
