The A&D Apollo GX-124AE is a 122 g capacity analytical balance that reads in 0.0001 g increments. That is the same as 0.1 mg readability. Buyers also search for this model as AND GX-124AE, A and D GX 124 AE, GX124AE balance, GX 124 AE scale and A&D Apollo 122 g analytical balance.

The GX-124AE is designed for laboratories that need 0.1 mg resolution, internal calibration and active static control without the extra capacity of the GX-224AE or GX-324AE. Its built-in fanless ionizer is particularly useful with plastic containers, powders and dry environments.

A&D GX-124AE specifications

Maximum capacity: 122 g.
Readability: 0.0001 g, equal to 0.1 mg.
Repeatability: 0.0001 g.
Linearity: ±0.0002 g.
Typical minimum weight: 120 mg, based on the manufacturer’s stated reference method.
Typical stabilization: approximately 1.5 seconds at 100 g in FAST mode under good conditions.
Weighing pan: 90 mm diameter.
External dimensions with large glass breeze break: approximately 259 x 358 x 332 mm.
Calibration: internal.
Static control: built-in fanless ionizer.

Why choose the 122 g model?

Capacity should be based on the combined weight of the sample, vessel, paper or other tare. The GX-124AE makes sense when that total stays comfortably below 122 g and the work benefits from its repeatability and linearity specifications. If routine vessels approach the capacity limit, moving to the GX-224AE or GX-324AE may provide a better operating margin.

Internal calibration and the Apollo AE package

GX identifies the internally calibrated branch of the Apollo family. The AE package includes the large glass breeze break with a fanless ionizer. The comparable GX-124A retains internal calibration but is not the same integrated-ionizer configuration, while the GF-124A uses external calibration.

Internal adjustment is convenient after temperature changes or scheduled intervals, but laboratories still need independent checks appropriate to their method. A balance can display the correct increment while still being affected by drafts, vibration, static, poor leveling, off-center loading or unsuitable test weights.

Common applications for the GX-124AE

Pharmaceutical and nutraceutical sample preparation.
Analytical chemistry and quality-control laboratories.
Research and university laboratories.
Small-parts counting or comparison work requiring 0.1 mg increments.
Formulation and botanical testing with low-mass samples.
Work with plastic vessels or powders where an ionizer can reduce static-related instability.

GX-124AE versus GX-324AE

The GX-124AE and GX-324AE share 0.1 mg readability, a 90 mm pan, internal calibration and built-in ionizer. The GX-124AE offers 122 g capacity; the GX-324AE offers 320 g. The GX-124AE has listed repeatability of 0.0001 g and linearity of ±0.0002 g. The larger GX-324AE is the better choice for heavier containers, while the 124 model is attractive when the lower capacity is sufficient.

Frequently asked questions about the GX-124AE

Is the GX-124AE an analytical balance or a precision balance?

With 0.0001 g (0.1 mg) readability and a glass breeze break, it is normally described as an analytical balance.

Does the GX-124AE calibrate internally?

Yes. The GX designation in this Apollo configuration indicates internal calibration.

What does the ionizer do?

It neutralizes electrostatic charge that can cause unstable or biased readings. It is helpful, but the operator must still control drafts, vibration, temperature and handling.

Is GX-124AE the same as GX-124A?

No. Both use internal calibration, but the GX-124AE is the integrated-ionizer configuration. Confirm the full suffix when comparing quotes or replacement units.

Is this model NTEP approved?

Do not assume the standard GX-124AE is legal for trade. N-designated versions are separate configurations. Verify the complete model and applicable certificate for any commercial transaction.

What should I check before ordering?

Check total loaded weight, required uncertainty and minimum weight, vessel diameter, environmental conditions, interface requirements, ionizer need, calibration procedure and any legal-for-trade requirement.
