Through Kalliope, operators can quickly understand operational procedures via the streamlined single-interface methodology (parameter configuration, data collection, and interpretation). The device's QC functionality delivers reproducible, precise measurements through customizable access protocols and parameter restriction. The apparatus operating in QC mode furnishes a straightforward indication regarding conformance to predetermined specifications.
Consequently, measurements materialize within three selections with diminished operator preparation requirements. Furthermore, a pharmaceutical variant incorporating data safeguarding protocols, access management, and transaction documentation is integrated, establishing Kalliope's alignment with the US FDA's 21 CFR Part 11 requirements.
Efficient Dispersion, Maximum Safety

Litesizer DIF's Quick-Click technology attaches the dispersion unit with a singular motion, eliminating complications involving connectors, tubing, or conduits. In addition, the opacity measurement display permits observation of specimen quantity during introduction, guaranteeing appropriate proportioning from initial application.
The dispersion units incorporate protective design elements. The Dry Jet dispersion mechanism features a vacuum verification and an integrated protective enclosure to mitigate powder dispersal hazards. Additionally, the Liquid Flow dispersion mechanism performs automated verification of adequate liquid presence preceding sonication, circumventing thermal stress.
Particle Sizing in Any Environment

Anton Paar's Litesizer DIF is designed to meet the demands of demanding industrial sectors. Construction incorporates superior-grade materials throughout, accompanied by a 10-year warranty on laser components. Durable steel casing safeguards precision optical components.
Litesizer DIF demonstrates resilience in challenging operational settings: Contaminant particles and powder cannot infiltrate the optical platform of the apparatus, and the apparatus interior maintains separation from potential mechanical disturbances originating from operational zones. These characteristics result in reduced maintenance expenditures and restoration expenses.
Sharper Results with Image-Enhanced Diffraction
Interchangeability of dispersion units among Anton Paar's Litesizer DIA and Litesizer DIF configurations minimizes capital requirements and laboratory footprint. All Litesizer configurations operate through a unified computing infrastructure that uses the Kalliope platform.
