This valve incorporates an advanced seal design that is superior to alternative valves currently available from other manufacturers. A fluoroelastomer o-ring imparts resilience and a high degree of chemical resistance. A PTFE sheath, forming the primary seal, completely covers the fluoroelastomer o-ring, creating the ultimate barrier against aggressive, reactive substances while providing a totally inert surface.

These pressure tubes facilitate experiments requiring conditions such as pressurized inert atmosphere blanketing, addition of reactive gaseous reagents under pressure, containment of low boiling point solvents or samples at elevated temperatures, and so on.

We recommend that the maximum operating pressure should be limited to 600 kPa (6 bar, 87 psi) when using a thin wall pressure tube, up to 1200 kPa (12 bar, 175 psi) if using a heavy wall pressure tube. (Please see accompanying table for complete details).

3mm CODED CLOSED PORT BLUE HARBOR SAMPLE VAULT CAPS FOR AUTOMATED SAMPLE TUBE SYSTEM, 96PK - U.S. PATENT NO. 8,054,080

Standard Series™ NMR Tubes, 25 Pack

• 5mm
• 200MHz 
• 7 Inch (178mm)
• For Routine NMR

Our “Standard Series™” NMR tubes are manufactured out of ASTM Type 1 Class B glass, commonly referred to as N-51A. Applications that are suited for using this type of glass are routine NMR where samples are run under room temperatures with no thermal gradients. It is therefore not recommended to fuse this glass with standard vacuum manifolds and the like, since these are generally made out of Type 1 Class A glass. Each NMR tube is checked for concentricity and camber specifications utilizing the latest computer technology.

Screw-Cap NMR Sample Tubes, 1 Pack 
Screw-Cap Septum NMR Tubes offer both convenience of a screw cap and that of a septum where material can be removed. Convenient screw-cap access with the security of a fluoropolymer (PTFE) seal. Supplied with open top cap & fluoropolymer/silicone septum for quick and clean access with a 22 gauge standard point needle.   

• 5mm
• 8" (203mm)
• 600 MHz
• Each Screw-Cap Tube comes complete with open top Polypropylene screw cap and PTFE/Silicone septum 
• Inert to most organic solvents and compounds but not recommended for use with strongly corrosive materials 
• Not recommended for multiple punctures
