Analytical Balances – 0.1 mg Precision Laboratory Weighing
Analytical balances are high-precision weighing instruments designed for quantitative laboratory work requiring readabilities of 0.1 mg (0.0001 g) or better. Used across pharmaceutical, chemical, academic, and quality control environments, analytical balances deliver the accuracy and repeatability required for gravimetric analysis, formulation, sample preparation, and compliance weighing.
Modern analytical balances incorporate internal motorised calibration mechanisms, electromagnetic force restoration (EMR) technology, and advanced draught shield designs to ensure stable, reproducible results even in demanding laboratory conditions. All models in our range are available with UKAS-traceable calibration certificates and are suitable for GLP and GMP regulated environments.
Key Features
- Readability to 0.1 mg — suitable for analytical and semi-micro applications
- Internal automatic calibration — motorised FACT/ICAL calibration triggered by temperature change or on demand
- Electromagnetic force restoration (EMR) — for consistent linearity and repeatability across the weighing range
- Draught shield enclosure — multi-section glass construction for rapid access and stable results
- GLP/GMP compliance — date/time stamping, user ID, and audit-ready data output
- RS-232 and USB connectivity — for direct data transfer to LIMS, printers, and PC software
- Capacities from 82 g to 520 g — across a range of platform sizes to suit sample volumes
- Ioniser compatibility — optional built-in or external static eliminators for lightweight or powder samples
Common Applications
- Pharmaceutical QC and R&D — API weighing, formulation, and dissolution preparation
- Chemical analysis — gravimetric determination and reagent preparation
- Academic and research laboratories — precise sample and standard preparation
- Food and beverage testing — moisture content, nutritional analysis, and ingredient formulation
- Environmental and materials testing — filter weighing, residue analysis, and loss-on-ignition
- Calibration and metrology — reference weight verification and mass comparisons
All analytical balances are supplied with a full accessory set and are available with UKAS-traceable calibration on request. Contact our team for guidance on balance selection, capacity, and readability requirements for your specific application.
Frequently Asked Questions
What is the difference between an analytical balance and a precision balance?
An analytical balance typically offers a readability of 0.1 mg (0.0001 g) and is enclosed in a draught shield to minimise the effect of air currents on results. A precision balance offers coarser readability — typically 1 mg to 0.01 g — and is used for less demanding weighing tasks where a draught shield is not required. The choice depends on the accuracy requirement of the application.
Do analytical balances require calibration?
Yes. Analytical balances should be calibrated regularly to ensure accuracy and traceability. Most modern analytical balances include internal automatic calibration (FACT or ICAL) that compensates for temperature drift throughout the working day. For regulated environments, periodic external calibration with UKAS-traceable weights is also required, and we offer UKAS calibration certificates on all models.
What capacity and readability do I need?
For most pharmaceutical and analytical chemistry applications, a 200 g capacity with 0.1 mg readability is the standard choice. Semi-micro balances offering 0.01 mg readability are available for more demanding applications. If larger sample volumes are required, 320 g or 520 g capacity models are available, though readability remains at 0.1 mg.
Are these balances suitable for GLP and GMP environments?
Yes. All analytical balances in our range support GLP and GMP documentation requirements, including date and time stamping, user identification, balance identification, and structured printout formats. Data can be exported via RS-232 or USB to laboratory information management systems (LIMS) or balance data software.
