Scales & Balances
Analytical and precision laboratory balances — milligram-level accuracy with draft shields, for research work that a kitchen or postal scale can’t touch.
An analytical balance and a top-loading balance solve different problems: analytical balances measure to 0.1mg or finer and use an enclosed draft shield to block air currents that would otherwise swamp that level of precision, while top-loading balances trade precision (usually 0.01g–1g) for a larger capacity and no draft shield, suited to bulk weighing rather than fine reagent measurement.
For most research applications — preparing reagents, weighing standards, quantitative analysis — an analytical balance is the right tool. Reach for a top-loading balance instead when you're weighing larger, less precision-sensitive quantities like bulk media components.
Every balance here lists its readability, capacity, and repeatability specifications, since those three numbers (not just the price) determine whether a balance is actually suited to your assay.
Frequently asked
Scales & Balances FAQ
- What is the difference between an analytical balance and a top-loading balance?
- An analytical balance measures to 0.1mg or finer precision and uses an enclosed draft shield to prevent air currents from affecting the reading. A top-loading balance offers lower precision (typically 0.01g–1g) but higher capacity and no draft shield, making it better suited to bulk weighing than fine reagent measurement.
- How precise is a laboratory analytical balance?
- Standard laboratory analytical balances read to 0.1mg (0.0001g), with some semi-micro and micro balances reading to 0.01mg or 0.001mg for specialized applications. Precision this fine requires a stable, vibration-free bench and a closed draft shield during weighing.
- How often should a lab balance be calibrated?
- Most labs calibrate analytical balances at least annually by a certified technician, with a daily or per-use check against a certified reference weight before critical measurements. Calibration frequency should follow your lab’s quality system requirements.
