We supply the most common 5 mm and
10 mm Spinner Turbines for Agilent (Varian) / Nalorac and Bruker NMR spectrometers.
The Spinner Turbines are manufactured to precision standards that meet or exceed those of the spectrometer manufacturers. A new 5mm PEEK version for Varian Spectrometers with superior VT performance and magnetic susceptibility has now also been released, as well as a POM based RT version for high throughput sample changers. The POM Spinner Turbine for Bruker Spectrometers incorporates two O-rings for ease-of-use and snug fit on the sample tube. The POM Spinner Turbines for Bruker Spectromters can also be used in high field NMR spectrometers.

Utilizing our 10 mm spinner turbines (V-GFK-10 and B-PEEK-10), a variety of microsample capillaries can be positioned (via Turbine Inserts) properly in the 10 mm turbines to be used with Varian / Nalorac 3 mm Probes and
Bruker 2,5 mm and 5 mm Probes. A substantial savings is realized considering the alternative of one-size spinner turbines form NMR probe manufacturers. The lower portion of each insert fits precisely into the 10 mm
Spinner Turbine. The upper portion of each insert holds a short 10 mm NMR tube that extends beyond the spinner turbinetop. This tube allows the set-up to be used with autosample changers that grasp the tube above the
spinner turbine. To reduce solvent evaporation, Capillary Tube Caps are available. The Turbine Inserts are not necessarily compatible with 10 mm turbines from probe manufacturers; hence, sets of spinner turbines
and inserts are made available. Additional different size inserts can be ordered for each set allowing the use of various size capillaries. All items are ordered separately for the full assembly, except Spinner Turbine
/ Insert Sets.
Insert Kits are available to improve NMR performance of small samples. Inserts provided to enable a user to measure small samples in small tubes, from 1.7mm up to 3.0mm, even if the NMR probe is 5.0mm. Spectral improvements gained from improved homogeneity over the smaller diameter, a crucial point if the RT shim system is not suitable for non spinning experiments, which now days is often the case with the latest new sequences. In addition substantial savings in solvent usage is also achieved, from 4 times less when going from 5mm to 3mm, to greater if smaller tubes are used. Kit contains 3.0mm, 2.5mm, 2.0mm and 1.7mm inserts and a full set of 10x125mm capillaries, barring 3mm, of which 2 are provided. Also included is a suitable 10mm spinner turbine for the appropriate spectrometer, and a set of syringes and PTFE needles for sample insertion and extraction from the small tubes.
