doty susceptibility plugs for nmr microsampling · easier to use than the glass alternative · can be used with a wider range of solvents · use them with existing tubes · lower in cost than glass · less fragile than susceptibility-altered glass microtubes traditionally sample sizes were 3-5 times the height of the probe r coil all magnetic field distortions caused by magnetic susceptibility discontinuities at the upper air-sample and lower glass-sample interfaces were far from the sensitive probe r coil region small samples diluted to larger traditional volumes 1 ml yield poor nmr spectra in high ...

spinner turbines we supply the most common 5mm and 10mm spinner turbines for varian/naloric and bruker nmr spectrometers the spinner turbines are manufactured to precision standards that meet or exceed those of the spectrometer manufacturers the fiberglass turbines are made from high density gfk fiberglass and incorporate a single o-ring imbedded at the turbine top hold the sample tube firmly into place a new 5mm peek version for varian spectrometers with superior vt performance and magnetic susceptibility has now also been released as well as a pet based rt version for high throughput sample changers ...
