5mm Economy NMR Tubes

Wilmad-LabGlass Economy NMR Tubes are manufactured from borosilicate glass that meets the ASTM Type 1 Class B standard and recognized as N51A. Due to its nature, this glass has much less thermal-shock resistance than Class A glass used for our Precision Tubes. It may contain Fe2O3 which is paramagnetic (1200 ppm) and has certain impact on shimming quality depending on the magnetic field strength. Economy tubes are recommended only for experiments with small organic molecule (Molecular Weight ~500) at ambient temperature only. The camber and concentricy listed in the product specification table is the upper limit value. Wilmad does not require a minimum purchase quanity. The unit price is one single tube. Each tube comes with a disposable cap.Cooling/heating of these tubes may lead to breakage. For NMR experiments that involve cooling, heating, biological sample, multi-dimension, multi-nuclei or DNP techniques; please refer to our Precision brand NMR Tubes. Some of our competitors altered our MHz rating standard by advertising inferior tubes for higher magnetic field experiments. Please visit our NMR Economy Tube Cross Reference Guide to make a head-to-head comparison including pricing. The products listed on the same row will have the same performance at the same magnetic field IF the specifications of our competitors' product are guaranteed as advertised. From this guide we will prove our 60 year philosophy again as "committed to providing customers with cost-effective NMR consumables of the highest quality".

10 mm NMR Economy Sample Tube w/ Cap, 7″ L, PK100, High-Throughput

10mm Economy NMR Tube

Wilmad-LabGlass 10 mm Economy NMR Tubes are manufactured from borosilicate glass that meets the ASTM Type 1 Class B standard and recognized as N51A. Due to its nature, this glass has much less thermal-shock resistance than Class A glass used for our Precision Tubes. It may contain Fe2O3 which is paramagnetic around 1200 ppm and has certain impact on shimming quality at high field over 600 MHz. 10 mm NMR tubes have an averaged camber of 60 micron to gurantee the spectrum reolution for small melecules (MW<500) samples up to 600 MHz. 10 mm Economy tube is ideal for MRI imaging applications. Item is sold in a pack of 100.

5 mm Precision NMR Sample Tube Low Pressure/Vacuum Valve (LPV) 7″ L , 600MHz

Low Pressure/Vacuum (LPV) 5 mm OD NMR Tube

Try our family of novel low pressure/vacuum tubes for NMR and EPR experiments as an alternative to other similar tubes. A 4X larger sealing surface eliminates leaks and greatly increases its lifetime when compared to traditional gas-tight tubes. It continues to offer a convenient flame-free sealing solution for air sensitive or volatile liquid samples at any pressure from vacuum to pressure slightly above 1 bar.Featured highlights: Greaseless PTFE piston provides a 100% contamination-free seal.Axial symmetric design guarantees its application in spinning experiments.More economical to reduce experimental costsReliable - standard sizes can ship within 1-2 business days after receipt of order.Spare/replacement Pyrextube available*For custom lengths contact Customer Service.

Specifications

  • MHz Rating:600
  • Camber/ Concentricity:13 / 6
  • Length (inch):7

Application Notes

*LPV Tubes consist of 3 parts - 5 mm Pyrex® vacuum adapter, 5 mm PTFE vacuum lock valve and piston assembly and an NMR tube with the threaded glass section sealed on; also known as the spare tube.For Spare Tube orders the original LPV part number must be specified; i.e. 528-LPV-7 as "X" denotes the style (528) and length (7").Important Note:Product numbers that include "PQ" belong to our Precision Tube Family with an OD and ID tolerance of 0.013 mm. Those with "SQ" are not Precision and their OD and ID may vary as much as 0.4 mm. For EPR experiments that must estimate electron spin density and/or produce highly repeatable signal amplitude between different runs we strongly recommend our Precision EPR Tube. Due to the nature of glass, Extreme Caution should be exercised when using at elevated or reduced pressures since a tiny scratch on the glass surface would significantly lower the tensile strength. Adequate safety shielding should always be used when working in these conditions.

5 mm Thin Wall Precision Quartz NMR Sample Tube 7″ L, 600MHz, Pack of 5

Quartz NMR Tubes

Advantages of Quartz: ~ Extremely low thermal expansion rate and high tensile strength. This feature makes quartz tubes 14 times more robust during cooling/heating process than corresponding Precision glass tubes.~ Naturally occurring quartz maintains over 85% transmission rate (10 mm thickness, with consideration of reflection loss) above 265 nm1.2, which makes quartz tubes preferable in photochemistry studies.~ Possesses a low Boron density as below 0.1 ppm, which guarantees a clean background in Boron-11 NMR studies.~ 2 times less dielectric constant than Pyrex® glass which helps improve the quality factor.Not recommended for EPR studies.
