BSA / BSA II Analytical Balance
The Sartorius BSA and BSA II analytical balances bring efficient, reliable routine weighing to the everyday lab: 60 g, 120 g or 220 g with 0.1 mg readability. A hybrid display, built-in application programs, USB Type-C and RS232 interfaces and automated internal calibration on the I-1x and -CW models make basic weighing simple, accurate and affordable.
Overview
The Sartorius BSA and BSA II Analytical Balances are designed for the routine demands of laboratory work: quality control, education and everyday weighing at 0.1 mg. German-designed and built for consistent readings, they let you weigh your sample and move on to the next task.
Models
BSA II (updated generation): BSA224I-1x and BSA224-1x (220 g), BSA124I-1x and BSA124-1x (120 g), BSA64I-1x and BSA64-1x (60 g). Models with I-1x have internal calibration and adjustment, models without it use external adjustment.
BSA: BSA224S-CW and BSA224S (220 g), BSA124S-CW and BSA124S (120 g). The -CW models have a built-in motorized internal calibration weight, the others use external adjustment.
Everyday weighing deserves the best technology
A hybrid display provides fast, accurate readings with up to 0.0001 g readability across the BSA II range of 60 g to 8,200 g.
Integrated application programs support daily routines with clear instructions and intuitive indicators: weighing, dosing, counting, percentage weighing, mixing, components, animal weighing, calculation, density determination, statistics and mass unit conversions, plus an underfloor weighing feature for large samples.
Automated calibration and adjustment on the I-1x models ensures maximum weighing accuracy and ease of use without manual test weights.
Connectivity and portability
BSA II has a USB Type-C port that automatically detects Sartorius printers or displays, and an RS232 interface that keeps it compatible with existing systems. With the converter cable YCC-5V-15V the balance can also be used portably.
Built to be dependable
The BSA series uses a monolithic weigh cell that reduces drift and protects against overload, and a housing made of chemical-resistant PBT plastic. An ergonomic glass draft shield minimizes air-current interference and can be taken apart for thorough cleaning.
BSA II analytical models have a Ø 90 mm weighing pan and a weighing chamber 200 mm high, and measure 219 × 317 × 306 mm (W × D × H). Our team can help you choose the right model and accessories.

Key features
- Hybrid display, 0.1 mg readability Fast, accurate readings on 60 g, 120 g and 220 g analytical models.
- Automated internal calibration BSA II I-1x models and BSA -CW models calibrate with an internal motorized weight, with no manual test weights needed.
- Integrated application programs Weighing, dosing, counting, percentage weighing, density determination, statistics and more guide your daily routines.
- USB Type-C and RS232 The USB Type-C port detects Sartorius printers and displays, and RS232 keeps the balance compatible with existing systems.
- Portable design (BSA II) With the converter cable YCC-5V-15V the balance goes wherever you need it.
Key advantages
- Basic weighing, done right Consistent readings with each use, so you can weigh your sample and move on to the next task.
- Monolithic weigh cell A single-block sensor gives long-term stability, fast response and high repeatability (BSA series).
- Protected against overload Built-in overload protection safeguards the weigh cell from accidental force (BSA series).
- Durable, easy to clean A chemical-resistant PBT housing and a glass draft shield that can be taken apart for cleaning.
- Wide range in one family BSA II covers 60 g up to 8,200 g, so one family suits many weighing tasks.
