Phoenix NMR manufacture and service solid state NMR probes.

TalaveraScience is the sales agency for Phoenix NMR throughout Europe, in Australasia and India.

Phoenix NMR has many years of experience in design of and making solid state NMR probes as the team originally working at Chemagnetics which was first acquired by Varian (1997) and then by Agilent Technologies (2009). Phoenix NMR probes are based on the latest version of Transmission Tuning Tube Technology (T3 Technology) to make very RF-efficient narrow bore (NB or SB) solid state NMR probes. These probes have a variety of tuning configurations such as the Phoenix HXY probe with HXY and HFXY

configuration and with interchangeable probe heads including 1.2, 1.6, 3.2, 4, 5, 6 mm and static probe head options and the Phoenix HX probe with a fixed probe head with the option of HFX performance providing a very cost effective double resonance probe. These probes are available for wide bore and standard/narrow bore magnets and are a high performance accessory for any NMR spectrometer, solids or liquids. Please read on for more information...

Phoenix HXY Probe Features...

Interchangeable Probe Heads

Phoenix HXY 1.6 mm Probe Head

Interchangeable Phoenix HXY Probe Heads are available for static horizontal samples, 1.2 mm, 1.6 mm (pictured to the left), 3.2 mm, 4 mm, 5 mm and 6 mm. There is a lock channel option for the 1.6 mm probe heads.

The VT exhaust is visible on the top of the probe head and interfaces with a funnel which passes through the solution state spinner assembly in the magnet. The VT input is on the Phoenix HXY Probe Base.

Phoenix HXY Probe Base

The Phoenix HXY Probe Base, depicted below, shows the available RF connections, the CamLock mechanism for holding the probe in the probe frame, the distinctive VT input with heat sink (the black item on the left) to avoid condenstaion and ice formation when running cold, Tachometry is compatible with most NMR spinning speed controllers (if not please see below for the Phoenix NMR spinning speed controller) making the probe highly versatile and future proof.

Phoenix HX NMR Probe Features

Phoenix HX Probe Top

Phoenix HX Probe Spinning System

The Phoenix HX Probe is a cost effective high performance solids MAS double resonance probe ideal for narrow (standard) bore magnets with or without high power amplifiers (50 W 1H and 100 W X amplifiers provide almost enough power to approach the maximum RF amplitude specifications) and is compatible with all of the manufacturers' NMR spectrometers. Ideal for solids capability on liquid state NMR spectrometers when equipped with the Phoenix NMR spinning speed controller.

Depicted on the left is an example of the fixed probe head spinning system. The Phoenix HX Probe is available from 300 to 700 MHz with spinning systems including 1.6 mm, 3.2 mm, 4 mm, 5 mm and 6 mm. The VT exhaust which interfaces with the VT funnel can be seen on the top of the spinning system as for the Phoenix HXY probe.

The 1H channel is tunable down to 19F with a simultaneous 1H/19F option available to give the Phoenix HX probe a HFX configuration! The X-channel is tunable from 31P to 15N.

Phoenix HX NMR Probe Base

In the picture above the RF channels and various connections are shown on the Phoenix HX probe base. Variable temperature operation is similar to that of the Phoenix HXY Probe with a slightly reduced temperature range. As with the Phoenix HXY Probe, there is a minimal temperature offset and gradient.

Phoenix NMR Accessories and Services

A range of accessories is available including the low-gamma box, the Phoenix Cool Stream for extended low temperature experiments, BioSolids sample packing tools, prepacked NMR standards rotors and probe servicing.

Phoenix Low Loss FTS Adapter

PCS and FTS VT Adapter

The variable temperature adapter connects a PCS or FTS trunk to a Phoenix NMR probe and to a Varian or Agilent solids VT stack with minimal loss between the outlet and probe input.

Phoenix NMR Low Gamma Accessory

Phoenix NMR Low Gamma Accessory

The Phoenix NMR Low Gamma accessory is pictured to the right connected to a Phoenix HXY probe and extends the low frequency channel below 15N down to 15 MHz for both the full range of Phoenix HXY and Phoenix HX NMR probes.

If you have a low gamma accessory from your previous T3 probes, such as a Varian or Agilent low gamma accessory, then you will find that these are compatible with the Phoenix HXY and the Phoenix HX NMR probes.

Please speak to us if you need to access resonance frequencies that are below 15 MHz to see if we can extend the frequency range lower.

BioSolids Sample Packing

Phoenix NMR Biosolids Packing Tools

Phoenix NMR offers BioSolids sample spacers and centrifuge sample packing tools for 1.6 mm and 3.2 mm rotor sizes.

These tools, along with the moulded silcone spacers make it easy to efficiently transfer your pelleted sample from 200 µl ultracentrifuge tubes into a ready to use rotor that will keep your sample hydrated.

If you are interested in spacers and tools for a different rotor size, please contact us with your request.


Phoenix NMR offers sample kits in 1.6 mm, 3.2 mm and 4 mm narrow bore rotor sizes working with all Phoenix NMR probes as well as Varian and Agilent PENCIL MAS narrow/standard bore probes to calibrate pulse widths, set the magic angle, measure sensitivity and check lineshape. These include:

  1. potassium bromide, magic angle setting;
  2. adamantane, 1H, 13C pw90 and 13C lineshape;
  3. 15N labelled glycine, 15N pw90, 13C sensitivity for 1.6 mm;
  4. hexamethylbenzene, 13C sensitivity for 3.2 mm and larger rotors;
  5. sodium hexafluorophosphate, 31P, 19F pw90;
  6. silicone powder, 1H shimming (much faster); and, if your probe has a lock channel;
  7. D2O, 2H pw90;

utilising the BioSolids sample spacers. An additional rotor is available to initially shim on 1H to aid final lineshape on 13C. Do you need a different size? Just ask!
