Laboratory Balances
Laboratory Scales & Balances for Precision Weighing
Precision and analytical laboratory balances for pharmaceutical, food testing, chemical analysis, education and industrial quality control. Our range from Kern, Ohaus and Adam Equipment covers readabilities from 0.001g (1mg) for routine precision weighing through to 0.0001g (0.1mg) for analytical applications. Every balance ships with a calibration certificate.
A laboratory balance is only as good as its fit for your specific application. The specifications that matter, readability, capacity, calibration type, and data connectivity, vary depending on whether you are running QC checks in a food lab, weighing active ingredients in a pharmaceutical facility, or teaching gravimetric analysis in a university.
Top-Tier Weighing Solutions
Precision balances typically offer readabilities of 0.001g to 0.01g and capacities from 200g to over 6,000g. They suit general laboratory weighing, formulation work, material testing, and education.
Analytical balances deliver readabilities of 0.0001g (0.1mg) or finer and usually come with draught shields to protect against air currents. They are essential for quantitative chemical analysis, pharmaceutical assay work, and any application where microgram-level accuracy matters.

Key Features & Capabilities
Many of our laboratory balances offer internal motorised calibration, which adjusts the balance automatically using a built-in reference weight whenever it detects a temperature change or at user-defined intervals. This is convenient for day-to-day operations and reduces the risk of drift going unnoticed.
External calibration uses certified test weights placed on the pan by the operator. This provides an independent verification and is often required alongside internal calibration in regulated environments such as pharmaceutical labs operating under GLP or GMP.
Both calibration types have their place. Many labs use internal calibration for routine work and schedule periodic external calibration checks as part of their quality management system.
Applications & Benefits
Regulated laboratories need more than just accurate readings. They need documented evidence. Look for balances with RS-232 or USB data output for connecting to printers, PCs, or LIMS systems. GLP-compliant printout capability produces timestamped records with device ID, calibration status, and operator information.
If your lab operates under ISO 17025, GLP, GMP, or HACCP frameworks, these connectivity and documentation features are not nice-to-haves. They are essential for audit readiness.
Our laboratory balances serve pharmaceutical labs (active ingredient assays, stability testing, raw material verification), food testing labs (nutritional analysis, moisture checks, portion control), chemical analysis (titration, gravimetry, sample preparation), education (teaching analytical technique), and industrial QC (incoming material checks, production monitoring).
For pharma and food labs specifically, we have written a focused guide on laboratory balances for pharmaceutical and food testing covering the compliance standards and specifications these sectors require.
If your lab also runs moisture analysis, our moisture analysers and dedicated analytical balances complement the precision weighing range.
Frequently Asked Questions
What readability do I need in a laboratory balance?
It depends on your application. For general lab work, formulations, and teaching, a precision balance with 0.001g (1mg) readability is usually sufficient. For analytical chemistry, pharmaceutical assays, and any work requiring microgram-level accuracy, you need an analytical balance with 0.0001g (0.1mg) readability or finer.
What is the difference between internal and external calibration?
Internal calibration uses a built-in motorised weight to automatically adjust the balance when temperature changes or at set intervals. External calibration uses certified test weights placed on the pan by the operator, providing an independent accuracy check. Many regulated labs use both, internal for convenience and external for audit-quality verification.
Do your laboratory balances meet GLP and GMP requirements?
Yes. Many of our balances feature GLP-compliant data output, RS-232 or USB connectivity for LIMS integration, and internal calibration with documented records. Combined with the calibration certificate included with every instrument and our ISO 9001:2015 registration, our balances support the documentation and traceability requirements of GLP, GMP, ISO 17025 and HACCP frameworks.
Which brands of laboratory balance do you stock?
We stock laboratory balances from Kern, Ohaus, and Adam Equipment. All three are established global manufacturers with decades of experience in precision weighing. Each brand offers a range of precision and analytical models at different price points, so there is an option for every budget and application.
