Sartorius, CUB36P-1S2-I, Cubis® III High-Capacity Micro Lab Balances

Cubis®III high-capacity micro balances are designed for laboratories that need microgram-level precision without compromising on load capacity. Wherever small sample sizes must be handled in large or heavy containers—such as 125 mL or 250 mL flasks, bottles, process vessels, or dense metal components—these balances provide the ideal combination of high readability and robust weighing performance. With readability in the 0.001 to 0.002 mg range and significantly increased maximum capacity, Cubis®III high-capacity micro balances close the gap between classic analytical balances and conventional microbalances. They allow users to weigh high-tare vessels and still precisely determine very small net sample quantities. This is particularly valuable in pharmaceutical and biotech laboratories, where APIs, reference standards, or high-value reagents are often dosed into large volumetric flasks or media containers, and in chemical and materials science labs handling heavier components and assemblies. The weighing system, based on high-performance monolithic technology, delivers excellent repeatability and long-term stability, even when working near the upper end of the capacity range. Intelligent compensation and high-quality mechanical design help to minimize the effects of temperature changes, air currents, and vibrations. This means users can rely on consistent results, whether they are preparing reference solutions, performing gravimetric filtrations with bulky filter holders, or determining mass changes in heavier samples for drying and decomposition studies. Cubis®III high-capacity micro balances are built with data integrity and regulatory compliance in mind. Comprehensive user management, audit trail, and electronic documentation functions support operation in regulated environments, including laboratories subject to GMP, GLP, and 21 CFR Part 11 requirements. Connectivity options, such as Ethernet and USB interfaces, enable seamless integration into laboratory information systems and digital data workflows, reducing manual transcription and the risk of errors. The balances can be configured with a range of accessories tailored to large or awkward sample containers: spacious draft shields with generous access, specialized sample holders and pans, licensable built in ionizer to mitigate electrostatic charges, and interfaces for integration into LIMS, ELN, or MES systems. Together, these features help streamline workflows such as formulation development, buffer and media preparation, gravimetric reference preparations, and in-process control weighing. In daily use, Cubis®III high-capacity micro balances combine ease of handling with uncompromising performance. They allow laboratories to standardize on a single, high-precision platform for both small and large samples, improving efficiency while maintaining the highest standards of accuracy, traceability, and compliance.
