Sartorius Cubis II Semi-Micro Balance, Model MCA225P-2S00-A

• Precise weighing of small samples in pharmaceutical research and development.
• Quality control and assurance in chemical and material science laboratories.
• Gravimetric analysis in environmental testing and food safety.
• Calibration of laboratory instruments and preparation of standard solutions.
• Forensic analysis requiring high accuracy and traceability.

Typical capacity

For this class of semi-micro balance, capacities commonly range from 60g to 220g.

Readability

Units of this type typically offer readability down to 0.01 mg or 0.001 mg.

Power supply

Most analytical balances operate on a standard mains power supply, commonly 230V AC, 50Hz for the UK market, often via an external power adapter.

Pan size

Typically, the weighing pan diameter for semi-micro balances is around 80-90 mm.

Draft shield

High-end semi-micro balances commonly feature an integrated, often motorised, draft shield to minimise air current interference.

Display type

Modern units frequently incorporate a high-resolution touch display for intuitive operation.

Connectivity

Common connectivity options include USB, RS232, and sometimes Ethernet for data transfer and integration.

Calibration

Units of this type often feature internal automatic calibration functions for consistent accuracy.

• What is the difference between a semi-micro balance and an analytical balance?

  A semi-micro balance offers higher readability and precision than a standard analytical balance, typically measuring down to 0.01 mg or 0.001 mg, compared to 0.1 mg for most analytical balances. This makes them suitable for smaller sample sizes requiring extreme accuracy.

• What maintenance is typically required for a semi-micro balance?

• Can this type of balance be used in a dusty or vibratory environment?

• What software features are commonly found on premium semi-micro balances?

• Is specific training required to operate a semi-micro balance?

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.
