EQR-200

Vibratory Ring Principle
Acoustic Enclosure
Frequency Inverter Motor
5-Program Memory
Automatic Lid Lock

The EQR-200 uses pressure and friction between a ring and puck set to reduce samples to sub-45 µm in under 60 seconds. Its sound-absorbing acoustic enclosure keeps laboratory noise levels low, while the automatic lid interlock prevents access until the motor has fully stopped.

EQR-200 Acoustic Enclosure — Noise and Vibration Control

Acoustic Enclosure + Frequency Inverter

High-Throughput Grinding, Low Noise Output

The EQR-200's dedicated acoustic enclosure absorbs vibration and sound. The frequency-inverter-driven asynchronous motor provides gradual acceleration and deceleration, reducing both mechanical stress and noise floor.

🔒
Automatic Lid Interlock
The lid remains locked until the motor reaches a full stop. Physical access during operation is blocked; no risk of unintended intervention.
📱
3.5" Color LCD and 5-Program Memory
Speed (750–1500 rpm) and time (0–99:59 min:sec) are set via the full-color LCD. Frequently used grinding profiles are stored in 5 programmable memory slots.
🔄
High Reproducibility
Particle size distribution spread between consecutive grinds of the same material stays below 1%. Consistent results for routine XRF analysis.

Frequently Asked Questions

What You Wonder About

With the right bowl and program combination, most samples reach sub-45 µm in under 60 seconds. For harder materials, times may be longer; the recommended maximum cycle is 120 seconds.

The dedicated acoustic enclosure absorbs vibration and sound. The EQR-200 operates within standard laboratory noise levels in both analytical labs and production environments.

For XRF analyses targeting Fe, Cr, or Mn, steel bowl contamination can affect results. Tungsten carbide bowls are recommended for these applications.

The frequency-inverter motor and gradual speed profile reduce mechanical wear. Routine maintenance primarily involves cleaning the bowl and ring sets. Contact the Anka Analitik technical team for service schedules.
