Radwag Analytical Balances – 0.1 mg Precision for Pharmaceutical & Research Laboratories
Radwag analytical balances are high-precision laboratory instruments designed for accurate sub-milligram weighing in pharmaceutical research, analytical chemistry, quality control, and scientific research environments. With readability to 0.0001 g (0.1 mg) and capacities from 82 g to 520 g, they deliver the exceptional accuracy required for sample preparation, API weighing, gravimetric analysis, reference standard preparation, and compliance testing in regulated and demanding laboratory settings.
Manufactured in Poland by Radwag — one of Europe’s leading precision weighing instrument manufacturers — their analytical balance range is built on electromagnetic force restoration (EMFR) weighing technology, delivering the linearity, repeatability, and long-term stability required for the most demanding laboratory applications. Automatic internal calibration using motorised reference weights ensures the balance self-corrects for temperature drift throughout the working day without operator intervention — a critical feature in regulated environments where calibration traceability must be maintained. Fully enclosed draft shields with sliding glass doors eliminate air current interference at 0.1 mg resolution, while anti-static ionisers and environmental sensors further stabilise readings in real-world laboratory conditions. Colour touchscreen displays with intuitive menu navigation simplify operation, and RS-232, USB, and Ethernet connectivity enable seamless data transfer to LIMS, printers, and laboratory software. GLP/GMP compliance features including audit trail, user management, and 21 CFR Part 11 compliant data integrity are available on selected models for regulated pharmaceutical environments.

Frequently Asked Questions
What makes Radwag analytical balances suitable for GMP and regulated environments?
Radwag analytical balances include automatic internal calibration with full traceability, GLP-compliant printed output, audit trail logging, user login and access management, method-guided workflows, and 21 CFR Part 11 compliant data integrity on selected models — the core requirements for regulated pharmaceutical, GMP, and ISO 17025 laboratory environments.
Do Radwag analytical balances include a draft shield?
Yes. All Radwag analytical balances include a fully enclosed draft shield with sliding glass doors on all sides. The draft shield is essential at 0.1 mg readability to eliminate air current interference from ventilation, nearby movement, or operator breathing. Always close all doors before taking a reading.
What is the difference between Radwag analytical balances and their precision balances?
Radwag analytical balances offer readability of 0.1 mg (0.0001 g) and always include a fully enclosed draft shield. Their precision balances offer readability of 1 mg (0.001 g) or coarser. For sub-milligram weighing tasks — such as API weighing, trace analysis, or reference standard preparation — an analytical balance is required.
Can Radwag analytical balances connect to my LIMS?
Yes. Radwag analytical balances feature RS-232, USB, and Ethernet connectivity for direct data transfer to LIMS, spreadsheet software, and data logging applications. Contact us for compatibility advice specific to your laboratory software environment.
Are UKAS calibration certificates available?
Yes. UKAS-traceable calibration certificates are available on request for all Radwag analytical balances. Annual recalibration is recommended to maintain accuracy and compliance — contact our team to arrange calibration documentation or periodic service support.
