Quick Pressure Valve (QPV) 5 mm OD NMR Sample Tubes

Wilmad Quick Pressure Valve Sample Tubes are specially designed to simplify the work of NMR/EPR studies for catalysis, gas-liquid phase reactions, air sensitive samples and elevated temperature studies using low boiling point solvents. Due to the nature of glass, Extreme Caution should be exercised when using at elevated or reduced pressures as performance of tubes under pressure or vacuum cannot be guaranteed. Adequate safety shielding should always be used when working in these conditions.. Wilmad Quick Pressure Valve Sample Tube Instruction The upper portion of the Quick Pressure Valve (QPV) is ready to accept 1/16” PTFE tubing. To make a connection, unscrew the top nut and ferrule from the top threaded port, and slide them onto the 1/16" tubing. Please make sure that the end of the tubing extends past the end of the ferrule. Screw the assembly back until its finger tight.  The Quick Pressure Valve could also be connected to 1/8" tubing through optional adapters. The following picture depicts the basic connection to 1/16" tubing and optional connection to 1/8" tubing:  If connecting the QPV valve to an existing glass vacuum manifold through a rubber hose is needed, please refer to the picture below for parts:   After assembly

Quartz and Suprasil Capillary Tubes

Wilmad Clear Fused Quartz and Suprasil® capillary tubes are often used in EPR applications where sample sizes are limited. Available in sizes from 0.40 to 2.4mm OD, these fine tubes are 100mm long and open on both ends. Easy to seal with a hot flame, you can use them with a round bottom or close with a sealant of your choice (beeswax is commonly used.)

Application Notes

Wilmad does not offer tubes for dosimetry. Please contact the manufacturer of your dosimeter for information about these special sample tubes.

4 mm Thin Wall Graded Seal Quartz EPR Sample Tube 275 mm OAL

EPR Graded Seal Sample Tubes

Need to seal an EPR tube to your vacuum rack? Some EPR samples are air-sensitive. Since oxygen is paramagnetic, many EPR samples are best studied after degassing. For long-term storage, no other closure is better, but most vacuum racks incorporate Pyrex® components. Sealing quartz to Pyrex® is a problem, unless you use sample tubes that incorporate a graded seal. Order Wilmad's Graded Seal/Constricted EPR Tubes, available in a variety of sizes. Other configurations can be prepared, so if you don't see the size you need, contact us about price and availabiility.

Specifications

  • Quartz Tube Length:250mm
  • OD (mm):4
  • ID (mm):3

Application Notes

Save Time Heat-Sealing EPR Samples! Heat-sealing quartz tubes is difficult enough so we've provided an easier way. By ordering our constricted tube you'll seal EPR tubes more quickly, with less effort. Choose your tube, add the suffix "CONS" to the product number and remember to order 1 inch longer than required.

PTFE Tube and 5mm OD Glass Adapter; Both Ends Open

PTFE-FEP Tube Liners for Corrosive Samples and 29Si NMR

PTFE-FEP contains no silicon which makes it ideal in29 Si NMR experiments. We manufacture high field 500 MHz rating open-ended tubes as an adapter to the 5 mm spinner turbine. Please use depth gauge to fine adjust the position of liner so no glass protrudes in the R f coil limit.

Application Notes

Note: The PTFE tube used in this kit is not interchangeable with PTFE liner (P/N 6005).
