Sapphire NMR Tubes Diameter 5mm/10mm Length 100mm/Custom lengths
Abstract
A sapphire NMR tube is a specialized nuclear magnetic resonance
(NMR) tube made from sapphire material (aluminum oxide, Al₂O₃).
Unlike conventional glass NMR tubes, sapphire NMR tubes offer
several advantages, especially in high-temperature, high-pressure,
and strong magnetic field environments.
Common Sizes of Sapphire NMR Tubes
1.Diameter:
5 mm: This is the most common size, suitable for small sample volumes
and general NMR analysis.
10 mm: A larger diameter, typically used for experiments requiring a
larger sample volume.
2.Length:
100 mm (standard length): The most common length for general NMR
applications.
Custom lengths: Sapphire NMR tubes can also be customized in lengths, generally
ranging from 100 mm to 200 mm, depending on the experimental needs.

Characteristics of Sapphire NMR Tubes
1.High Strength and Durability: Sapphire is known for its exceptional hardness and strength, which
makes it resistant to mechanical stress and breakage, providing a
more durable alternative to traditional glass tubes.
2.High Temperature Resistance: Sapphire can withstand extremely high temperatures, making it
suitable for NMR experiments that require elevated temperatures.
3.Magnetic Field Stability: As a non-magnetic material, sapphire does not interfere with the
strong magnetic fields used in NMR instruments, providing a more
stable experimental environment.
Chemical Stability: Sapphire is chemically inert and resistant to
corrosion, making it ideal for experiments with reactive or
corrosive chemicals.
4.Optical Transparency: Sapphire NMR tubes are highly transparent, which can be beneficial
in experiments that also require optical detection or analysis.

Applications
1.High-Temperature and High-Pressure Experiments: Sapphire NMR tubes are suitable for experiments conducted under
extreme conditions, such as high temperatures or pressure, where
traditional glass tubes might fail.
2.Corrosive Environments: Due to its chemical stability, sapphire NMR tubes are ideal for
use in experiments involving highly reactive or corrosive
substances.
3.Precision Analysis: The stability and durability of sapphire tubes ensure more
accurate and reliable results, especially in experiments that
require precise measurements or repeated testing.
Q&A
Q:What Factors Should Be Considered When Choosing the Size?
A:1.Sample Volume: A 5 mm diameter tube is suitable for smaller sample volumes,
while a 10 mm tube is better for larger samples.
2.Magnetic Field Requirements: Some NMR experiments may require specific tube sizes to ensure
uniformity of the sample in the strong magnetic field.
3.Experimental Conditions: The tube size might affect the performance of the experiment
under extreme conditions such as high temperature or pressure.
