SPINMASTER FFC2000 (the fast Field Cycling NMR relaxometer) is a unique NMR instrument designed to measure the field dependence of NMR spin-lattice and spin-spin relaxation time T₁ and T₂ (Nuclear Magnetic Relaxation Dispersion profiles) from 10 kHz to 40 MHz (¹H Larmor frequency).

The system consist of the following units: 1 Tesla wide-bore electromagnet, double circuit magnet/power supply cooling system; 3 NMR probes working in different frequency range; variable temperature controller system for sample temperature control with 0.1 °C precision in the range of - 120 to + 140 °C; local magnetic field compensation system for low Field Relaxometry and Personal NMR Console with Software package: AcqNMR32.

The compact model of SPINMASTER FFC2000 with the electromagnet. The switching time between the polarization, relaxation and detection magnetic field can be 1 ms.

Bruker AVANCE spectrometer coupled to a vertical wide-bore (90-mm) magnet operating at 7.046 T (300 MHz for ¹H). Special accessories like a gradient system, microimaging probehead, and the sophisticated imaging package allowed to performed the NMR imaging. The maximal gradient strength in x, y and z direction is 100 G/cm. The probehead for protons has four interchangeable coils of the diameter 5, 10, 15 and 25 mm. For small samples ¹H imaging with 2D resolution of about 10 µm are obtained in our laboratory. The Para Vision software supports a variety of special processing functions including statistical analysis in regions of interest and 3D surface reconstruction. The following imaging methods are performed on our spectrometer:

Gradient Echo Fast Imaging (GEFI)
Multislice/Multiecho (MSME), T2 calculations
Snapshot FLASH Method
Contrast imaging
Diffusion imaging (SEDIFFUSION, STEDIFFUSION)
Constant time/ single point imaging (CTI/SPI)
Localized spectroscopy (VOSY,VSEL)
Chemical shift imaging (CSIND)

Bruker NMR pulse spectrometers (SXP 4-100 and MSL 300) with two electromagnets (2.2 T and 1.2 T) and superconducting magnet with a maximal field up to 8.4 T with set of NMR probe-heads for ¹H, ²H ¹⁹F nuclei.

Two helium continuous flow cryostats (Oxford and Leybold) and one liquid nitrogen temperature controller (Bruker).
