Cubis® III semi-micro balances are designed for laboratories that require both high resolution and robust weighing capacity in a single instrument. Positioned between micro and analytical balances, they offer readability down to the microgram range while providing practical weighing ranges for everyday laboratory tasks. This makes them ideal for applications such as sample and standard preparation, handling of reference substances, formulation work, content uniformity testing, and quality control in pharmaceutical, chemical, and academic laboratories.
At the core of each Cubis® III semi-micro balance is a high-stability weighing system developed to deliver excellent repeatability and minimal drift, even during long measurement series. Advanced compensation technology helps reduce the influence of environmental factors such as temperature changes, air currents, and mechanical vibrations. As a result, users can rely on consistent measurement performance, whether the balance is installed in a dedicated weighing room or in a busy analytical laboratory.
Cubis® III semi-micro balances are available in a wide range of configurations, allowing the instrument to be precisely adapted to individual workflows. Different weighing capacities and readabilities, various draft shield concepts, and a selection of weighing pans and accessories provide maximum flexibility. For routine operation, features such as motorized draft shield doors, automatic taring, and built-in leveling support help simplify daily tasks and reduce user influence on the measurement result.
The intuitive user interface is based on a high-resolution touchscreen that guides users step by step through methods and workflows. Predefined and customizable applications — for example, percent weighing, density determination, differential weighing, filter weighing, and pipette calibration — support standardized and reproducible procedures. Users can easily enter sample IDs, batch numbers, or method parameters and store or export results in a structured way.
Cubis® III semi-micro balances are developed with a strong focus on data integrity and regulatory compliance. Comprehensive user management, audit trail, and electronic documentation functions support operation in regulated environments, including laboratories working in accordance with GMP, GLP, and 21 CFR Part 11 requirements. Connectivity options, such as Ethernet and USB interfaces, enable easy integration into laboratory information systems and digital data workflows, reducing the need for manual data transcription and minimizing the risk of errors.
The balances can be configured with a range of accessories tailored to larger or awkward sample containers: spacious draft shields with generous access, specialized sample holders and weighing pans, a licensable built-in ionizer to reduce electrostatic charge, and interfaces for integration into LIMS, ELN, or MES systems. Together, these features help optimize workflows such as formulation development, buffer and media preparation, gravimetric preparation of reference solutions, and in-process control weighing.
In daily use, Cubis® III semi-micro balances combine ease of handling with uncompromising performance. They allow laboratories to standardize work on a single high-precision platform for both small and larger samples, improving efficiency while maintaining the highest standards of accuracy, traceability, and regulatory compliance.
