Sample Preparation / XRF Sample Preparation

EQM-402

Horizontal Oscillation
Simultaneous Dual Bowls
Dry and Wet Grinding
Touchscreen Control
5-Program Memory

The EQM-402 uses horizontal oscillation (up to 32 cycles per second) to drive grinding balls against the sample, achieving sub-10 µm in 1–4 minutes. Two bowls run simultaneously; it reduces fusion time and is the ideal compact benchtop unit for XRF pellet and fusion bead preparation.

EQM-402 — Ground XRF Samples

Horizontal Oscillation + Rapid Homogenization

XRF-Ready Samples in Minutes

The EQM-402's horizontal oscillation mechanism drives grinding balls against the sample at high frequency. The result: homogeneous sub-10 µm powder in a short cycle and a measurable reduction in fusion time.

⚡
Simultaneous Dual-Bowl Processing
Two 50 ml bowls run at the same time, doubling laboratory throughput and reducing waiting time in routine analysis workflows.
🔥
Shorter Fusion Time
Sub-10 µm fineness accelerates flux homogenization during fusion. Melt time and energy consumption are significantly reduced.
💧
Dry and Wet Grinding
Supports both dry powder grinding and wet grinding for specialized applications. Ball diameter and count adjust the final particle size independently.

Frequently Asked Questions

What You Wonder About

Samples with a feed size below 5 mm typically reach sub-10 µm in 1–4 minutes. Time depends on ball diameter, sample hardness, and speed setting.

Two 50 ml bowls run simultaneously. This doubles laboratory throughput and reduces waiting time in routine analysis workflows.

Oscillation frequency and time are set via the touchscreen. The number and diameter (10–25 mm) of balls in the bowl control impact force; together they provide a wide achievable size range.

Yes. The instrument produces homogeneous sub-10 µm powders for blending with binder, pressing XRF discs or pellets, and reducing fusion cycle time.

Yes. The EQM-402 supports both dry and wet grinding. A liquid may be added to the bowl for specialized wet grinding applications.
