Questions about Sample vials & NMR tubes

Which NMR tube suits my spectrometer?

The MHz rating on an NMR tube indicates its quality class: how straight and concentric the tube is. Choose a rating at least equal to the field strength of your spectrometer; a lower class can broaden lines. Choose the length, such as 5, 7 or 8 inches, to suit your probe and sample changer. For air- or moisture-sensitive samples, a tube with a valve keeps the sample sealed, as with the NMR tube, 5 inch, 400 MHz, with valve. Deuterated solvents are in dry and deuterated solvents.

Screw-thread, crimp or snap vial: which closure should I choose?

A screw-thread vial is easy to open and close by hand, can be reclosed and suits most storage and sample work, as with the clear glass sample vial, 40 ml, thread 24-414. A crimp vial is sealed with an aluminium cap and a crimper, which gives the tightest closure for volatile samples and headspace work. A snap vial closes quickly without tools and suits high sample numbers where a perfect seal matters less. Caps and septa for each closure are in vial caps and septa. Questions? Ask sales@luminixhealth.com.

Clear or amber glass?

Choose amber glass for light-sensitive samples, such as vitamins, many pharmaceuticals, dyes and some pesticides; it filters a large part of UV and blue light, as with the crimp vial, 20 ml, amber. Choose clear glass when you want to check the sample visually, for example for colour, particles, phase separation or fill level, such as the sample vials, 30 ml, with screw thread. If a sample is light-sensitive but must also be inspected, amber glass with storage in the dark is the safe choice. Caps are in vial caps and septa. Questions? Ask sales@luminixhealth.com.

Which volume do I need, and when should I choose a vial with a septum?

Choose the volume for your sample size plus headspace: a vial filled to the top leaves no room for expansion or mixing, while a nearly empty vial lets volatile compounds escape into the gas phase. Larger vials, such as the injection vials, borosilicate glass, 50 ml, suit bigger samples and headspace work. Choose a cap with a septum, usually PTFE on silicone, when you pierce the vial with a needle or syringe, or when the sample is volatile and must stay sealed between withdrawals. Septa are in vial caps and septa. Questions? Ask sales@luminixhealth.com.

Why Sample vials & NMR tubes?

A sample vial is a small closed bottle for keeping or for presenting a sample. An NMR tube is a precision glass tube: the wall has to be straight and the diameter has to match the probe, or the spectrum contains the tube.

A tube holds a small sample upright. A test tube is the open glass or plastic cylinder. A centrifuge tube is conical so a pellet forms at the tip, and it is rated for a centrifugal force the rotor will actually reach. A vial is a small closed bottle, often for a sample that will sit in an instrument. NMR tubes are a special case: the glass has to be uniform or the spectrum is the tube, not the sample. Laboratory ware is listed under ISO laboratory glassware.
