Introducing the Lab-Tools MK4 NMR Spectrometer.

This time-domain NMR Spectrometer also has increasing frequency domain capability and is a very able instrument for materials science.
With T1, T2, T1rho, and support for process measurement and control, it's perfect for a variety of applications. Weighing in at just 1kg - ruler is just 6" / 15cm long - it's a compact and powerful tool. The MK2 and MK3 versions have already been used in about 50 published papers : ORCID: 0000-0002-8967-4671

The MK4 NMR Spectrometer is now available from Lab-Tools Ltd. for nano-science research.
A range of NMR Magnets at 0,.3T to 0.5T are available for use with this MK4 NMR Spectrometer. Thermo-electrically cooled variable-temperature NMR probes are also available..

Measures NMR Relaxation times T1, T2, T1rho, using standard sequences; offers support for Materials Science, and process measurement and control.

A highly compact but precision instrument with versatile graphical user interface;
NMR physical measurements on both liquids and solids;
T1rho spin locked measurements of slow molecular dynamics;
Graphical User Interface giving control, data analysis, display and data storage is on a Windows 10 or 11 computer;
Can be operated locally, from elsewhere on the LAN, or remotely over the internet;
Is suitable for both laboratory bench and mobile applications;
Excellent signal-to-noise, good R.F. pulse strength;
Minimal sample needed in 5mm or 3mm NMR tubes;
A cutting-edge instrument, the R.F. is processed digitally in a Field Programmable Gate Array (FPGA);
Thus highly stable for long term process measurements;
New NMR pulse sequences may be added in a high-level language;
1H, 19F, 7Li, 31P, 23Na nuclei all observable with appropriate NMR probe and magnet, 2 to 50 MHz;
Increasing support for frequency domain measurements at up to 90 MHz.

Optional Variable-Temperature Probe :

Peltier thermo-electrically cooled variable-temperature probe -45C to +80C;
Ideal for Material-Science measurements as a function of temperature;
Enables the measurement of both sample component masses and qualities which are variously described as mobility, dynamics, stiffness, viscosity or rigidity.
Peltier cooling gives extreme stability, around 10mK;
This enables the measurement of nano-pore to micro-pore pore-size distributions using the technique of NMR Cryoporometry, sub-nm to over 1 micron pore diameter :
Polymers, porous rock, clay, glass, ceramic, carbon, wood, biochar, rubber, artificial skin ......
