Coaxial Small Volume Inserts
Coaxial Small Volume Inserts
Switch between three unique sample/reference solution ratios during external referencing experiments.
- Ideal for variable temperature experiments since material remains the same between the outer tube, inner tube and spacer
- Insert and outer tube in complete set systems are fused together at the bottom; recommended for high field experiments under 600 MHz
- For ultra high field experiment over 600 MHz, order an inner tube, two spacers and a Wilmad Precision Thin-Walled Tube over 600 MHz separately
Considered to be the most versatile and reliable coaxial system available for various NMR experiments. Coaxial Small Volume Inserts have a number of applications; including small volume NMR, external referencing or locking and magnetic susceptibility determination.
Goss Scientific aim to bring you the most extensive range of NMR tubes available and will do whatever we can to provide a reliable and trusted source of peripherals to aid and further NMR-based research.
