Dry Powder Dispersion

Standard auto-locking dry measurement cell cassette for the Mastersizer 3000 laser diffraction system. The cell type is automatically recognised by the software when the cell is placed into the optical bench. Includes a unique window locking mechanism enables rapid cleaning of the cell following measurements, without the need for additional tools. A filtered sheath air system ensures sample deposition on the windows is minimised during measurements. The measurement zone within the cell is enclosed, so as to reduce sample exposure to the user. This cell will work within any Mastersizer 3000 or Mastersizer 3000E dry dispersion unit.

Standard sample tray with hopper for use with the Aero S dry powder disperser.

Micro volume sample tray for use with the Aero S dry powder disperser.

Macro volume sample tray for use with the Aero S dry powder disperser.

Funnel sample feeder upgrade kit designed to aid routine QC measurement by enabling samples to be added directly to the Aero S or Aero M dry powder dispersion units without requiring the accessory cover to be opened. This kit provides all of the components required to upgrade an existing Aero S or Aero M unit. Note: use of this kit requires Mastersizer 3000 software version 3.20 or higher (a copy of the latest software is provided with this kit). Note: The funnel sample feeder cannot be used with magnetic materials. It has been tested with large free flowing samples (e.g. coffee), cohesive samples (e.g. calcium carbonate) and samples with densities > 2 g/cm3 (e.g. cement, glass). As always, applications testing is advised before it is supplied.

Standard stainless steel venturi disperser for use with the Aero S dry powder disperser. This venturi is configured for the dispersion of a wide range of materials, including samples containing fragile particles.

High Energy stainless steel venturi disperser for use with the Aero S dry powder disperser. This disperser includes an impaction plate, enabling the dispersion of robust particles which are strongly agglomerated. Note: this disperser is not recommended for use with fragile particles.

Standard ceramic venturi disperser for use with the Aero S dry powder disperser, configured for the dispersion of a wide range of materials. Note: This disperser is only recommended for cement or abrasives producers and should not be specified for potentially explosive powders.

High-energy ceramic venturi disperser for use with the Aero S dry powder disperser. This includes an impaction plate which enables the dispersion of robust particles which are strongly agglomerated. Note: This disperser is only recommended for cement or abrasives producers and should not be specified for potentially explosive powders.

Aero S automated dry powder dispersion system, designed to achieve the reproducible dispersion of both fragile and robust powder samples over a wide size range. Ideal for applications where large sample quantities need to be measured, or where the speed of dispersion and fast sample turn-around associated with dry powder measurements are important. Includes a vibrating sample feed system, for precise sample delivery, along with the interchangeable venturi disperser geometries, which can be selected and configured according to the specific requirements of any application. Direct software control of dispersive air pressure (0-4bar, 0.1bar precision), sample feed rate (0-6g), vacuum sample collection and clean sequences is provided. Automatic detection of the venturi disperser and sample feed tray types ensures the correct configuration is used for each measurement. Supplied, as standard, with a hopper-based sample feed tray (MAZ2060) and a vacuum control unit (MAZ2080). Flow path is constructed of 316 and hardened 410 stainless steel, borosilicate glass, EPDM, PTFE, Polyurethane, Aluminium, Carbon filled acetal, Neoprene. Maximum measureable particle size is 3500 microns (sample dependant). Requires, but does not include, a venturi disperser (MAZ2070 - MAZ2073), a dry measurement cell (MAZ2050), a clean dry compressed air supply of 90psi (6 bar) at a flow rate of at least 90l/min, as provided by the COM0035/36 compressors, as well as an industrial vacuum system, such as VAC0067/68, for sample collection. NOTE: (1) Any alternative to the VAC0067/68 must not be rated at more than 2.7kW @220v or 1.3kW @110v. (2) In the event that any alternative to the COM0035/36 compressor is installed, it will be essential to install filter FIL0027 or equivalent in the airline. Failure to observe this requirement will invalidate the warranty for this dispersion unit. (3) The Aero S cannot be used with the venturi dispersers designed for the Aero M (MAZ3500) unit.
