Rubber fittings for nuclear magnetic resonance (NMR) instruments are often used to provide sealing and waterproofing to protect the internal components of the instrument.
O-ring: Used to provide sealing for pipes, joints and connecting parts to prevent leakage of liquid or gas.
Rubber gasket: Used to provide cushioning and sealing functions at connecting parts of the instrument, such as the connection points of sample tubes.
Diaphragm: Used to protect the port of the NMR tube to prevent sample entry or leakage.
Rubber plug: Used to seal holes or channels in instruments to prevent dust, impurities, or liquids from entering.
Sample tube plug: used to close the sample tube opening of the NMR instrument to prevent the sample from leaking or entering external impurities.
Air plug: used to close the air channels of the nuclear magnetic resonance instrument, such as gas inlets and outlets.
Sealing plug: used to close the connection holes of the nuclear magnetic resonance instrument, such as magnetic field calibration holes, liquid nitrogen injection holes, etc.
Probe plug: used to close the NMR probe interface of a nuclear magnetic resonance instrument to protect the internal components of the probe from contamination or damage.
These rubber plugs are usually made of materials with good chemical resistance and high temperature resistance, such as nitrile rubber (Nitrile Rubber) or silicone rubber (Silicone Rubber). They need to have good elasticity and sealing properties to ensure the normal operation and accuracy of the NMR instrument.
Rubber tube: used to connect different parts of the instrument or to connect to external equipment, such as gas pipelines or liquid pipelines.
These rubber accessories are usually made of materials with good chemical resistance and high temperature resistance, such as nitrile rubber (Nitrile Rubber) or silicone rubber (Silicone Rubber).
Rubber plugs in nuclear magnetic resonance (NMR) instruments are often used to seal holes or channels in the instrument to prevent the entry of dust, impurities, or liquids. Here are some examples of common NMR instrument rubber stoppers
Rubber gaskets in liquid chromatographs (HPLC) are mainly used to provide sealing and leak-proof functions to ensure the stability and reliability of the system. Here are some examples of common rubber gaskets used in liquid chromatographs:
Inlet gasket: Located between the inlet and the syringe, it is used to ensure sealing during sample injection.
Column connection gasket: Located between the chromatographic column and the column connector, it is used to ensure the sealing of the column connection.
Pump connection gasket: Located between the liquid chromatography pump and the injector, it is used to ensure the sealing of the connection between the pump and the injector.
Detector gasket: Located at the inlet and outlet of the liquid chromatograph detector, it is used to ensure the sealing of the detector components.
These rubber gaskets are usually made of materials with good chemical resistance and high temperature resistance, such as nitrile rubber (Nitrile Rubber) or polytetrafluoroethylene (PTFE). They need to have good elasticity and corrosion resistance to adapt to the chemical solvents and conditions in the liquid chromatograph.
During the use of the liquid chromatograph, these rubber gaskets may become worn or aged due to long-term use or the influence of chemical solvents. Therefore, regular inspection and replacement of rubber gaskets is an important step in maintaining the performance and accuracy of your liquid chromatograph.
Laboratory instruments are equipment and tools used for scientific research, experiments, and analytical testing.
Microscope; centrifuge; spectrophotometer; gas chromatograph (GC); liquid chromatograph (HPLC); mass spectrometer; nuclear magnetic resonance (NMR); thermogravimetric analyzer (TGA); particle size analyzer; pH counter
Rubber rings and gaskets have a sealing and protective effect on these laboratory instruments. In order to obtain accurate test data.
