BSA / BSA II Precision Balance

The Sartorius BSA and BSA II precision balances bring efficient, reliable routine weighing to the everyday lab: from 220 g up to 8,200 g with 1 mg, 10 mg or 100 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 Precision Balances are designed for the routine demands of laboratory work: quality control, education and everyday precision weighing. German-designed and built for consistent readings, they let you weigh your sample and move on to the next task.

BSA II (updated generation): each model comes with internal calibration (I-1x) or external adjustment (no I)

1 mg, with draft shield (Ø 120 mm pan): BSA623 (620 g), BSA423 (420 g), BSA323 (320 g) and BSA223 (220 g).
10 mg, open pan (182 × 182 mm): BSA6202 (6,200 g), BSA4202 (4,200 g), BSA3202 (3,200 g), BSA2202 (2,200 g) and BSA822 (820 g).
100 mg, open pan (182 × 182 mm): BSA8201 (8,200 g), BSA5201 (5,200 g) and BSA2201 (2,200 g).

BSA (earlier generation): each model comes with a built-in motorized internal weight (-CW) or external adjustment

1 mg: BSA623S, BSA423S, BSA323S and BSA223S. 10 mg: BSA822 and BSA6202S, BSA4202S, BSA3202S, BSA2202S. 100 mg: BSA8201, BSA5201 and BSA2201, each also as -CW.

Everyday weighing deserves the best technology

A hybrid display provides fast, accurate readings across the BSA II range of 60 g up 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 and -CW 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. BSA II milligram models have a Ø 120 mm pan and a weighing chamber 200 mm high and measure 219 × 317 × 306 mm (W × D × H); the 10 mg and 100 mg models have a 182 × 182 mm open pan and measure 219 × 317 × 94 mm. Our team can help you choose the right model and accessories.

Key features

Hybrid display for fast readings Fast, accurate readings on 1 mg, 10 mg and 100 mg precision 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.
Fast response Typical stabilization time of 1.5 seconds or less on BSA II 1 mg models and 1.0 second or less on the 10 mg and 100 mg models.
Monolithic weigh cell A single-block sensor gives long-term stability, fast response and high repeatability (BSA series).
Durable, easy to clean A chemical-resistant PBT housing and, on 1 mg models, a 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.
