The A&D Apollo GX-324AE is a 320 g analytical balance with 0.0001 g readability. Because 0.0001 g equals 0.1 mg, searches for “A&D GX-324AE 320 g x 0.1 mg” and “GX 324AE 320 g x 0.0001 g” describe the same resolution. Other natural name variations include AND GX-324AE, A and D GX 324 AE, GX324AE and A&D Apollo analytical balance.

This model combines internal calibration with a large glass breeze break and a built-in fanless ionizer. The combination is intended to control two common sources of analytical weighing error: changes in balance sensitivity and electrostatic charge on samples or containers.

A&D GX-324AE specifications

Maximum capacity: 320 g.
Readability: 0.0001 g, equivalent to 0.1 mg.
Repeatability: 0.0002 g at 300 g and 0.0001 g at 200 g.
Linearity: ±0.0003 g.
Typical minimum weight: 120 mg, based on the manufacturer’s stated reference method.
Typical stabilization: about 1.5 seconds at 100 g and 2 seconds at 300 g when set to FAST in a good environment.
Weighing pan: 90 mm diameter.
External size with large glass breeze break: approximately 259 x 358 x 332 mm.
Calibration: internal.
Static control: built-in fanless ionizer.

What does the GX-324AE model name mean?

Within A&D’s Apollo family, GX models use internal calibration, while comparable GF models use external calibration. The AE configuration adds the large breeze break with integrated ionizer. That makes the GX-324AE different from the GX-324A, which has internal calibration but not the same built-in ionizer package, and from the GF-324A, which uses external calibration.

Why a built-in ionizer matters

Static can pull or push on a sample without adding real mass. Plastic weigh boats, filters, powders and low-humidity environments are common trouble spots. The GX-324AE ionizer helps neutralize charge before or during weighing. A stable bench, proper leveling, closed breeze-break doors and temperature-equilibrated samples remain important.

Useful applications

Pharmaceutical, nutraceutical and formulation laboratories.
Quality-control and research work requiring 0.1 mg increments with more capacity than a 120 g analytical balance.
Botanical, chemical and food laboratories working with charged powders or plastic containers.
Universities and teaching laboratories needing internal calibration and data connectivity.
Counting, percent weighing, comparison and other supported analytical workflows.

GX-324AE versus GX-124AE

Both models display 0.0001 g (0.1 mg) increments and use a 90 mm pan, internal calibration and built-in ionizer. The major difference is capacity: the GX-124AE is rated to 122 g, while the GX-324AE reaches 320 g. The lower-capacity model has tighter listed linearity and repeatability. Choose the GX-324AE when containers or samples exceed the practical capacity of the GX-124AE; choose the smaller model when maximum capacity is less important than its stronger low-capacity performance specification.

Calibration and verification

Internal calibration improves convenience and helps compensate for environmental change, but it is not a substitute for a documented verification program. Laboratories should level and warm up the balance, use appropriate traceable test weights, check repeatability and eccentricity where required, and follow the manufacturer’s instructions and their own quality system.

Frequently asked questions about the GX-324AE

Is 0.1 mg the same as 0.0001 g?

Yes. One gram contains 1,000 milligrams, so 0.0001 g converts to 0.1 mg.

Does the GX-324AE have internal calibration?

Yes. A&D identifies the GX-324AE as an internally calibrated Apollo analytical balance.

Does it include an ionizer?

Yes. The AE configuration includes a built-in fanless ionizer in the large glass breeze-break assembly.

Is the GX-324AE NTEP legal for trade?

The standard GX-324AE should not be assumed legal for trade. A&D uses separate N-designated configurations, such as GX-324AEN, for applicable NTEP approvals. Confirm the exact model number and certificate before using any balance for transactions based on weight.

What should be confirmed before purchase?

Confirm required capacity, readability, minimum-weight and uncertainty targets, pan and container size, ionizer need, data interfaces, calibration policy, accessories and any regulatory approval required by the application.
