KERN ALS 250-4A — analytical balance with 250 g range and 0.0001 g readability
The KERN ALS 250-4A is an analytical balance designed for pharmaceutical, research and material‑testing applications, combining a fine readability with a large working range and an intuitive graphic display for efficient laboratory routines
- High readability 0.0001 g for exact results
- 250 g range for larger samples
- Graphic LCD with clear plain‑text guidance
- Built‑in recipe storage for repeatable dosing
Accurate results, proven quickly
The ALS 250-4A delivers high-precision weighing through a force‑compensation system that yields a readability of 0.0001 g and a reproducibility of 0.0001 g, making it suitable for analytical tasks that require consistently tight tolerances. Short stabilisation times (stable values in around 4 s under laboratory conditions) reduce throughput bottlenecks and increase sample throughput. Linearity of ±0.0003 g supports traceable measurements across the range, and the compact stainless steel weighing pan (Ø 80 mm) paired with a three‑door glass windscreen prevents drafts affecting the result. Technical terms: force‑compensation describes a weighing mechanism that balances the load electronically rather than by mechanical levers, which improves long‑term stability and precision.
Practical functions for routine workflows
Workflows are simplified by the graphic LCD with plain‑text operator guidance in multiple languages and an internal memory for complete recipes including ingredient names and target values. The integrated checkweighing mode allows upper and lower limits to be entered and supports portioning with optical and audible signals, while the dosage aid and selectable high‑stability filter options help to obtain the target mass faster and with less rework. Ergonomically arranged controls and a large weighing chamber (B×T×H 160×170×225 mm) support safe handling and easy access for both left‑ and right‑handed operators, reducing handling errors during dosing or sorting tasks.
Robust design and laboratory compliance
Constructed for frequent use, the housing includes a protective work cover supplied with the instrument and a stainless steel weighing plate that resists routine wear. The model offers a CAL calibration programme for adjustment of accuracy; external test weights are available separately where verification or laboratory accreditation is required. Environmental tolerances (operation 5 °C to 35 °C, relative humidity up to 80%) match typical laboratory conditions. Power is supplied via a multi‑region adapter set (AUS, CH, EURO, UK, US), enabling immediate commissioning across locations. Applications listed for this instrument include pharmaceuticals, materials testing, and research and development, where repeatable small‑mass measurements and recipe management are essential.

FAQ
What is the smallest reliably measurable sample on this balance?
The KERN ALS 250-4A offers a readability of 0.0001 g; for routine guidance the USP minimum sample weight and practical minimums depend on the sample handling and environmental conditions, and the instrument’s specifications should be used for method validation.
Can recipes and formulations be stored on the balance?
Yes, the analytical balance features an internal memory for complete recipes with names and target values, enabling repeatable dosing and streamlined batch workflows.
How does the CAL programme work for verification?
The built‑in CAL calibration programme allows users to perform a calibration routine using external test weights (sold separately) to adjust and verify accuracy in accordance with laboratory procedures.
Is the instrument suitable for pharmaceutical and research applications?
The balance is designed for pharmaceutical, research and material‑testing applications where high readability, recipe management and checkweighing capabilities are required; its specifications support traceable laboratory use.
Which power adapters are supplied with the unit?
The unit is supplied with power adapters for AUS, CH, EURO, UK and US, allowing commissioning in multiple territories without the need for additional adapters.
