The Magnettech ESR5000 is a high-performance, compact bench-top EPR spectrometer designed for both academic and industrial laboratories. Delivering research-grade sensitivity, wide magnetic field sweep capability, and unmatched ease of installation, it enables advanced paramagnetic analysis without requiring extensive infrastructure.

High Sensitivity & Stability

1. Operates at X-band frequency with sensitivity of 5 × 10⁹ spins/G (5 × 10¹⁰ spins/mT), enabling detection of rare paramagnetic species.
2. Microwave power adjustable from 1 μW to 100 mW.
3. Concentration sensitivity as low as 20 pM (some sources reference 50 pM).
4. Exceptional field homogeneity (± 5 µT within the sample region) and field stability of just 1.0 µT/hour.
5. Offers wide magnetic field sweep range: up to 6500 G (–100 to 6500 G).
6. Sweep resolution supports over 125,000 points.
7. Modulation frequency options: 10 kHz and 100 kHz.
