High Pressure NMR Cell Manifolds and Tubes:
Static Pressure Cell: To the left is the cell designed for quantitative static pressure experiments. This cell, when inside the NMR, requires attachment to an external pressure generator by way of a high pressure line for maintenance of a target pressure. This also allows for the pressure inside the tube to be altered for multiple point pressure measurements.
The high pressure fitting is 1/2"-20 for use with 1/8" tubing. This cell is designed to work at pressures up 3.0 kbar. The cell is easily assembled using two open-end wrenches.
Bruker and Varian versions are available. All tubes can be used in this device, including the 1 kbar rated, high volume tube shown on the reverse micelle NMR products page.
Per manifold $1,200 (tube not included)
NMRCELL - B (Bruker) or NMRCELL - V (Varian)
High Pressure NMR Tubes:
With a sample volume equal to about half that of a standard 5 mm glass NMR tube these specialized tubes allow for high resolution triple-resonance spectroscopy to be performed on samples up to 2.5 kbar. They are offered in a range of pressure tolerances:
1.5 kbar NMR tube (HPTUBE-1.5 kbar): 3 mm I.D. x 5 mm O.D. tube. $6,000 each.
2.0 kbar NMR tube (HPTUBE-2.0 kbar): 3 mm I.D. x 5 mm O.D. tube. $7,500 each.
2.5 kbar NMR tube (HPTUBE-2.5 kbar): 3 mm I.D. x 5 mm O.D. tube. $10,000 each.
These tubes are very robust. They can withstand rough handling including drops off a bench without losing structural integrity. Each tube is pressure certified before shipping.
A manifold and tube is tested as single unit to assure optimal performance. Each main component is identified by serial number to assure this continued pairing. Documentation is also included for your records. When matched units are listed on a quote the NMR cell unit is identified as BNC - X.X KBAR for Bruker and VNC - X.X. KBAR for Varian.

Xtreme-60 Syringe Pump:
Forget about using an HPLC pump to pressurize your samples. Don't use a hand crank pump to try to maintain your quantitative pressure measurements over experiment times of days.
We are proud to offer the Xtreme-60 Syringe Pump for use in high pressure NMR applications. It is capable of delivering and maintaining pressures up to 60,000 psi (4 kbar) without requiring user invervention.
Operation is simple: enter the set point and hit run. The pump does the rest of the work. Would you like to do a series of pressure points? The Xtreme can be programmed for multi-point pressure titrations and data logging of the steps.
The Xtreme works with both liquids and gases. Incompressible fluids such as water or light oils can be used as the pressurizing fluid without overstressing the pump drive train.
Specifications:
Pressure Accuracy: 4 bar (Xtreme-60 model)
Pump: 12" W x 29" D x 10.5" H (not including cables)
Controller: 11" W x 17" D x 6" H (not including cables)
System Weight: 120 lbs (55 kg)
Universal Electrical Input: 85-265 VAC (47-63 Hz)
Approved for use in the European Union (CE mark).
The Xtreme-60 is priced at $20,850.

High Pressure Seals (TS01): These form the primary seal between the high pressure tube and manifold. They are single use. One version works for all tube and cell combinations.
Support Equipment:
Safety Box: This acrylic walled box provides protection to users while pressurizing cells. It also helps protect the setup while moving samples from the bench to the spectrometer. It also provides a convenient place to store high pressure cells when not in use. The box is open on the bottom.
Bruker and Varian versions are available.
Price: $800
Cell Setup Tool: The high pressure tubes are not permanently fixed in the cell to allow for tubes to be switched and cleaned independently. This benefit requires some care when assembling the high pressure cell. This tool assists in that process by helping to keep the tube axially aligned with the cell during setup which improves seal integrity and lowers the probability of improper fit in the NMR.
Only one is needed for each cell type (Varian or Bruker)
Price: $300

Typical High Pressure Setup:
Listed below is the equipment that might be purchased for a high pressure setup for 45 samples up to 2.5 kbar pressure.

(1) Cell Setup Tool
(1) Safety Box
(75) TS01 tube seals
The high pressure tubing and fittings required to connect to an external pressure source are not included with the cell since some customers already have such components. However, we can add lengths of tubing to an order upon request.
It is possible to use the syringe pump for pressurizing multiple cells provided an external valve is added inline between the pump and the NMR tube. This arrangement allows switching off between different samples and allows for storing of samples in the tube at modest pressures (i.e. ~0.5 kbar to slow any cell growth) between uses in the NMR.
