Sartorius LA4200S Balance

• Precise measurement of samples in chemical and pharmaceutical research.
• Quality control in manufacturing processes requiring accurate mass determination.
• Formulation and compounding in laboratories and industrial settings.
• Educational purposes for teaching precise weighing techniques.
• Material testing and analysis where small mass variations are critical.

Typical capacity

For this class of analytical balance, capacities commonly range from a few hundred grams up to several kilograms, with readability in milligrams or centigrams.

Readability

Units of this type typically offer readability down to 0.01 g, suitable for precision weighing tasks.

Weighing pan material

Commonly, a stainless steel weighing pan is used for durability and ease of cleaning.

Calibration

Many precision balances feature automatic internal calibration for consistent accuracy.

Communication interface

RS-232 is a commonly found communication port for data transfer to external systems.

Power supply

Typically operates on standard laboratory mains power, often 230V AC in the UK, via an external power adapter.

Footprint

For a top-loading balance of this capacity, the footprint is generally compact, designed for benchtop use.

Construction

A solid diecast metal base is typical for stability and robust construction.

• What is the difference between an analytical balance and a precision balance?

  Analytical balances typically offer higher readability (often to 0.1 mg or better) and usually feature a draft shield. Precision balances, like this unit, offer slightly lower readability (e.01 g to 1 mg) but often higher capacities and are generally more robust for everyday lab use.

• Does this balance require regular calibration?

• Can this balance be connected to a computer for data logging?

• What kind of environment is suitable for operating this balance?

• Are spare parts readily available for Sartorius balances?

Analytical balances remain essential lab tools valued for precision and reliability across pharmaceutical, biotech and research settings. Buyers typically prioritise calibration history and service records when purchasing used models, as proper maintenance directly affects measurement accuracy. Industry sentiment recognises these instruments as durable investments; common strengths include consistent performance and straightforward operation. When evaluating used units, inspect for visible wear, verify calibration certificates, and confirm availability of spare parts and technical support for the specific model.
