Analytical Lab Balances
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.

Key features of BSA / BSA II Analytical
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 of BSA / BSA II Analytical
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.
About BSA / BSA II Analytical
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.

Frequently asked questions: BSA / BSA II Analytical
BSA II is the updated generation with a hybrid display, USB Type-C and RS232 interfaces and models with internal calibration marked I-1x. The earlier BSA analytical models are BSA224S, BSA224S-CW, BSA124S and BSA124S-CW.
BSA II models with I-1x in the code and BSA models ending in -CW have internal calibration and adjustment with a motorized internal weight. The others are calibrated with an external test weight.
Analytical models of 60 g (BSA II), 120 g and 220 g, all with 0.1 mg readability.
The BSA II analytical models have a typical stabilization time of 2.0 seconds or less. The BSA analytical models have an average response time of 2.5 seconds.
For routine daily use it is best practice to calibrate at least once a day and again if the room temperature changes significantly or the balance is moved to a new place.
BSA II has a USB Type-C port that detects Sartorius printers and displays automatically, and an RS232 interface for existing systems.
Keep the balance plugged in and let it warm up for at least 30 minutes before operation so that the internal components reach their optimum temperature.
