Economy and High Throughput NMR Sample Tubes

3mm Economy NMR Tubes
With the steady increase of SNR on modern NMR spectrometers, the trend of small volume testing fits in high-throughput NMR to save on solvent costs. Wilmad-LabGlass presents a 3mm OD Economy Sample Tube with the same outstanding quality and performance as our legendary 5mm line. The new 4″ version is designed for Bruker’s SampleJet system and possesses a tighter tolerance for use with the SampleJet cap which is sold separately. All are shipped in our reusable polyethylene Twist-Pack which provides contamination-free, chemically resistant and mechanically robust protection.  

Our WG-3000 Economy Sample Tubes – No Silkscreen or Sandblast. Order Caps Separately.

Our 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 Fe₂O₃which is paramagnetic and has certain impact on shimming quality.  

Economy brand tubes are recommended only for 1D NMR experiments with small organic molecule (Molecular Weight <1500) at ambient temperature. 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.  

Special Alert:
Recently some of our competitors altered our MHz rating standard by advertising inferior tubes for higher magnetic field experiments. 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”.  

N E W !!!!!!
Introducing our new 50 Pack! Compared to traditional paper packaging, this reusable polyethylene Twist-Pack provides contamination-free, chemically resistant and mechanically robust protection for your NMR tubes. It is a perfect fit for labs with less demanding NMR tests on small organic molecules.

NMR/EPR Tube Caps

Disposable NMR Tube Caps
Wilmad’s Disposable NMR Tube Caps are made from high quality Polyethylene or Ethylene Vinyl Acetate depending on the O.D. of the tube.
Different colors help to track samples based on various reference solvents.
Packaged in bags of 25, 100 or 1000.
Please avoid using disposable NMR caps when CDCl3 serves as the reference solution as the material(s) could be dissolved. For CDCl3, we recommend PTFE tube caps shown on the next page. 

 NMR/EPR Tube Caps – PTFE
Wilmad’s PTFE NMR Tube Caps are machined to exact specifications with smaller gyroradius and more homogeneous mass distribution than disposable caps for better spinning stability. These caps are recommended in experiments at high-ultra high field and experiments using Chloroform as reference solution. Will fit Precision Brand NMR Tubes only due to the tight tolerance.  

NMR/EPR Tube Caps – Gas-Tight
The Gas-Tight NMR Tube Caps are ideal for experiments that require an air-tight environment under vacuum or low pressure less than 1 bar. Use these caps with Wilmad Medium-Walled and Heavy Walled NMR tubes for better seal and robustness in variable temperature experiment.
#990 Gum Rubber Caps allow easy access via syringe needle.  

 Septa, NMR, White Rubber 

Our White Rubber Septa seals to 5mm O.D. thin wall Precision NMR tubes.  

Designed to maintain excellent glass to rubber contact; inject your sample or reactant into the NMR tube. Great for Air-Sensitive samples, Catalytic studies and Titration experiments. They are manufactured under “white room” conditions with certified raw materials for consistency.

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

For NMR investigations where chemical compounds such as hydrofluoric acid, ammonium bifluoride and concentrated hydroxide solutions are present, Wilmad’s PTFE-FEP NMR Tube Liner provides a contamination-free environment.
PTFE-FEP Tube liners are round-bottom and made from Teflon (Polytetrafluoroethylene /Fluorimated Ethylene Polypropylene copolymer). Thin-wall construction minimizes fillingfactor losses. Although the liners are not rigid, they straighten upon insertion into the sample tube. Not recommended for elevated temperature studies. A PTFE plug is included
with each liner.
PTFE-FEP material does not contain any silicon, which makes it ideal in 29Si NMR experiments. Wilmad manufactures high field 500 MHz rating open-ended tube as an adapter to the 5 mm spinner turbine. Please use the depth gauge to fine adjust the position of liner so that no glass part will protrude into the Rf coil limit.

Amberized NMR Tubes for Light Sensitive Samples

Wilmad can offer extra protection for your valuable light-sensitive samples in NMR studies via amberization on the Borosilicate NMR tubes. The transmission rate between 300 to 700 nm is lowered by several orders of magnitude after amberization. Just add’-AMB’ to the Product Number of the tubes that meet the requirement of your experiments.
The minimum order for amberization service is 5 tubes per order.  

Double Layered NMR Tube for Toxic Sample  

Wilmad’s Double Layered Tube provides extra protection for your toxic sample. It can also be used with a reference standard which is insoluable in the sample or may cause a reaction. Outer tube and inner tube has about 50 μm gap and the system is ideal for variable temperature studies as the components are made of same Pyrex® glass. Each insert fits snugly into the outer tube, like a syringe plunger fits its barrel.
