A&D Weighing GX-124A Apollo Analytical Balance, Internal Calibration, 122 g x 0.0001 g

The GX-124A provides a 122 g maximum capacity with 0.0001 g (0.1 mg) readability. A&D specifies 0.0001 g repeatability and ±0.0002 g linearity, making it suitable for pharmaceutical testing, research, formulation, sample preparation, quality control, and other laboratory applications requiring highly precise measurements.

Yes. The GX-124A features internal calibration with a built-in calibration mass, allowing users to perform routine sensitivity adjustment without handling a separate external calibration weight. The GX-A platform also supports automatic self-calibration, which can help maintain reliable weighing performance when temperature conditions change.

A&D's Electronically Controlled Load (ECL) technology allows the GX-124A to perform a repeatability check without requiring an external test weight. DSC states that the test takes less than 90 seconds and can provide information such as pass/fail status, standard deviation, and minimum sample weight, helping users assess balance performance and support precision weighing procedures.

Despite its fine 0.0001 g readability, the GX-124A is designed for fast analytical weighing. A&D specifies an approximate 1.5-second stabilization time at a 100 g load when the balance is set to FAST and operated under suitable environmental conditions. This can help improve efficiency during repetitive laboratory measurements.

Both models provide 122 g capacity, 0.0001 g readability, and internal calibration. The key difference is that the GX-124AE includes A&D's GXA-17 large glass breeze break with a built-in fanless ionizer, which helps neutralize static electricity on samples. The GX-124A is therefore a strong choice when users need high analytical precision but do not require an integrated ionizer for static elimination.
