Ohaus Analytical Balances – 0.1 mg Precision for Pharmaceutical & Research Laboratories
Ohaus 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.
Ohaus has over 100 years of weighing instrument expertise, and their analytical balance range reflects this heritage in every detail. 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 on all sides 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 application mode selection, 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 method-guided workflows support regulated pharmaceutical and quality management environments.

Frequently Asked Questions
What makes Ohaus analytical balances suitable for GMP and regulated environments?
Ohaus analytical balances include automatic internal calibration with full traceability, GLP-compliant printed output (date, time, balance ID, and results), audit trail logging, user login and access management, and method-guided workflows — the core requirements for regulated pharmaceutical, GMP, and ISO 17025 laboratory environments. The colour touchscreen interface simplifies method compliance and reduces operator error.
Do Ohaus analytical balances include a draft shield?
Yes. All Ohaus analytical balances include a fully enclosed draft shield with sliding glass doors on all sides — front, left, right, and top access. 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 Ohaus analytical balances and their precision balances?
Ohaus 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 and may not include a full draft shield. For sub-milligram weighing tasks — such as API weighing, trace analysis, or reference standard preparation — an analytical balance is required.
Can Ohaus analytical balances connect to my LIMS?
Yes. Ohaus analytical balances feature RS-232, USB, and Ethernet connectivity for direct data transfer to Laboratory Information Management Systems (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 Ohaus analytical balances. Annual recalibration is recommended to maintain accuracy and compliance — contact our team to arrange calibration documentation or periodic service support.
