Accessories for Liquid-Phase NMR

Spinner Turbines
Wilmad supplies a full range of Spinner Turbines for Varian/Nalorac and Bruker NMR spectrometers from 1.7mm to 10mm. These Spinner Turbines are manufactured to precision standards that exceeds spectrometers manufacturers’s products in terms of dimension tolerance, reliability and life span.

Spinner for Small Volume NMR (Bruker® MATCH® System)
Similar to Bruker® MATCH® system, Wilmad’s Spinner for Small Volume NMR holds a variety of microsample capillaries and is compatible with Bruker®, Varian®, JEOL®’s spectrometers/probes and automatic sample changers. A substantial savings is realized considering the“one size” variety available from NMR probe manufacturers.
The lower portion of each insert fits precisely into the Spinner Turbine; the upper portion holds a short 10 mm NMR tube (almost 4 inches long with open ends) that extends beyond the top. This set-up can be used with autosample changers that grasp the tube above the turbine.


 

Tube Washers

Universal solvent Jet NMR Tube Washer
Wilmad’s Universal Solvent Jet Washer can be used for any length sample tube by a simple adjustment of the flexible PTFE tubing. It is espcially recommended for cleaning our gas-tight sample tubes.
By loosening and retightening the tubing fitting on the assembled washer head, the PTFE tubing that extends into the sample tube is adjusted to the proper length. The washer head is then affixed to a filter flask (with sidearm) and the side tubing is inserted into a washing solvent reservoir. After an inverted sample tube is placed over the PTFE tubing, a vacuum is applied to the flask and the sample tube is pressed against the rubber gasket to form an air-tight seal that starts the solvent flow. By lifting the PTFE tubing out of the solvent reservoir, the sample tube can be air-dried.


Multi-Tube Jet Solvent NMR /EPR Tube Washer/Dryer
Wilmad’s new generation Multi-Tube Jet Solvent Washer/Dryer is recommended for research labs that routinely clean NMR/EPR tubes; a single unit can accommodate up to 5 tubes (5 mm OD) at once. When an inverted tube is inserted onto the PTFE tubing and the open end is immersed under wash solvent in the solvent cup, a reliable vacuum-tight seal will be formed and generate solvent flow under vacuum. After solvent is fully consumed, air flow will follow to
turn the unit into a dryer.

Features:
• Novel design significantly increases the reliability and performance compared to traditional jet solvent washer/cleaner systems.
• PTFE solvent cup and tubing make this unit fully resistant to common organic solvents.
• Greaseless joint between the solvent cup and glass reservoir eliminates possibility of contamination.
• Open design allows for easy cleaning after each use.
• Hands Free during washing/drying cycle.
• Detachable side-arm with screw thread provides convenient vacuum hose connection.



After fitting the washer to a filter flask, an inverted sample tube is inserted into the washer and solvent is introduced into the reservoir using a series of wash bottles. You can perform numerous wash steps and finish by pulling air through the tube to complete the procedure.
Filter flasks are ordered separately. The single tube washers (WG-1207-series)require flasks with vacuum sidearms (see below).

Economy Single Tube Solvent Jet Washer/Cleaner


Filter Flasks with Vacuum Sidearms
Filter flasks have a standard taper Ts 24/40 outer joint and are used with WG-1207 Economy Single Tube Washer and WG-7200 Universal Tube Washer.


Ultrasonic Cleaning Systems
The Ultrasonic Cleaning Systems can wash up to 20 tubes at a time and are recommended for NMR research facilities. Operating at 21,000 sonic vibrations per second, these versatile, compact units can be used with aqueous detergent solutions or organic solvents (tank manufactured from stainless steel).
These Ultrasonic Cleaners have a 1 gallon capacity. Tube Cleaning Rack is plastic-coated to protect tubes. Available in a number of configurations, e.g. with 0-30 min timer and/or heater (thermostated for 60 °C) these units provide up to 100 watts output while drawing a maximum of just 1 A input power.

Capacity: 1 gallon (approximately 3.8 liters)
Tank D imensions: 9” x 5” x 6” deep
Outer D imensions: 10 1/2” x 6 1/2” x 11” high

Liquid Nitrogen Dewar Flask

Liquid nitrogen is an easily transported and economic source of coolant, whose boiling point is far below the freezing point of water without pressurization. This unique feature makes liquid nitrogen extremely useful for a wide range of applications in basic science research, such as cell cryopreservation, sample degasification by freeze-pump-thaw cycle and cold trap for experiments involving vacuum lines.
Wilmad, the world’s leading provider in NMR/EPR consumables and accessories, now has a high quality Liquid Nitrogen Dewar Flask to meet these applications.
Features:
• 30% cheaper than other manufacturers’ similar products.
• Unique metal base increases stability.
• Optional full length aluminum metal housing can further increase safety and reduce potential breakage.
• High vacuum minimizes liquid nitrogen loss during storage.


Combination pH Electrode
For use in 5 mm thin-walled NMR sample tubes up to 8” in length. Glass probe dimensions are 3 mm O.D. x 180 mm length.


 NMR Long Tip Transfer Pipets and Accessories

NMR Filters and Powder Funnel
Sample sedimentation may bring trouble to both shimming and spectrum quality. Use Wilmad’s special Bulb Filter to remove large particles. Two designs available: one with luer tip for stainless steel needle attachment, the other with glass tip. Both fit into all sizes of Wilmad NMR tubes. The sintered glass tip removes particles larger than 60 μm.

Wilmad’s Powder Funnel is designed to load large amounts of liquid reagents into NMR tubes. Tip fits into 5 mm thin-walled NMR or larger tubes.


 

Hamilton® Gas Tight Syringes (PTFE Luer Lock)
Wilmad offers PTFE Luer Lock syringes that best meet your NMR sampling needs.
These syringes handle air-sensitive and/or volatile samples with precise control over sample volumes.
Features:
• Gas and Liquid Tight.
• Reproducible (volumes to ± 1%).
• Made of inert borosilicate glass, PTFE, and stainless steel.
• Pressure tight to 200 psi.


 

Syringe Needles
The stainless steel needle is designed for septum punctures for air-sensitive sample.
The PTFE version in various sizes offer a convenient way to load and wash your sample in Small Volume NMR experiments.

 
Turbine Height Adjuster for Auto Sample-Changer
Wilmad offers a solution to save your valuable time in NMR Auto Sample-Changer turbine height adjustment.
Each adjuster has a set screw that lets you adjust the position of the turbine along the tube to match your instrument. Two versions are available for Bruker®, Varian® and JEOL® systems.

 
Vortex Plugs and Positioning Rods
Recommended for sample positioning inside the NMR tube.

 
Pressure Sensitive NMR/EPR Tube Labels
Wilmad’s Pressure Sensitive NMR Tube Labels are a handy alternative to marking tubes. Each label fits the circumference of the NMR tube precisely with no overlapping to guarantee sample tube’s symmetry in spinning experiment.
