The A&D Borealis BA-225TE is a 220 g semi-micro balance with 0.01 mg readability. It may also appear in searches as AND BA-225TE, A and D BA 225 TE, BA225TE balance, BA 225TE microbalance or A&D Borealis semi-micro balance. The model combines very fine resolution with enough capacity for many vessels and laboratory workflows.

Its main operating features include a 5-inch color touch screen, automatic internal calibration, an external ionizer, touchless operation and automatic side doors on the breeze break. Those features are intended to improve repeatability in real laboratory work, where door movement, static and operator contact can disturb a fine measurement.

What makes a semi-micro balance different?

A conventional analytical balance commonly reads to 0.1 mg. The BA-225TE reads to 0.01 mg, ten times finer. That added resolution increases sensitivity to drafts, vibration, static, evaporation, sample temperature, handling and installation quality. Semi-micro capability is valuable only when the surrounding method and environment support it.

Touchless doors, ionization and cleaning

The side doors can be opened and closed with non-contact infrared sensors, reducing the need to touch the balance during a weighing sequence. A&D uses a pneumatic mechanism intended for quieter operation. The external ionizer helps remove static from the sample and container, while removable glass panes and a detachable breeze break make routine cleaning more practical.

These controls do not eliminate the need for good technique. Samples should reach temperature equilibrium, the balance should be level and protected from airflow, and operators should avoid leaning on the bench or handling vessels in ways that transfer heat or static.

Internal calibration and laboratory records

The BA-225TE can adjust sensitivity using its internal weight and can perform an internal repeatability test. It also supports user permission levels and an event history for settings and calibration activity. Those features can support controlled workflows, but the laboratory remains responsible for validating the method, setting tolerances and using appropriate traceable external standards when required.

Applications for the BA-225TE

Pharmaceutical formulation and analytical sample preparation.
Research laboratories measuring small mass differences.
Quality-control work requiring 0.01 mg displayed increments.
Environmental, chemical and materials laboratories.
Universities and regulated laboratories that benefit from access control and event records.
Work with powders, plastics or filters where static elimination is important.

BA-225TE versus a 0.1 mg analytical balance

Choose the BA-225TE when 0.01 mg readability is justified by the method and the lab can control the environment. A 0.1 mg analytical balance may stabilize faster, cost less and be easier to operate for routine work that does not need semi-micro resolution. The right decision depends on allowable uncertainty, minimum sample weight, vessel weight, throughput and documentation needs.

Frequently asked questions about the BA-225TE

Is the BA-225TE a microbalance or semi-micro balance?

A&D describes the 220 g x 0.01 mg model as a semi-microbalance. Some sellers use the broader term microbalance, so both phrases appear in searches, but 0.01 mg readability is generally classified as semi-micro.

Does the BA-225TE have internal calibration?

Yes. It uses internal automatic self-calibration and can run an internal repeatability test.

Does it have an ionizer?

Yes. The BA-225TE package includes an external ionizer; this is different from models that build the ionizer directly into the breeze-break assembly.

Are the draft-shield doors automatic?

The side doors can be operated by the infrared sensors on the display unit, and optional foot switches may also be used.

Is the BA-225TE legal for trade?

Do not assume it is approved for transactions based on weight. Legal-for-trade use requires an exact approved model and certificate for the jurisdiction. Treat the BA-225TE as laboratory equipment unless the supplied configuration is specifically documented otherwise.

What should be confirmed before ordering?

Confirm required capacity, minimum weight and uncertainty, container size, installation conditions, ionizer and door configuration, data connections, calibration policy, accessories and any regulatory requirements.
