1.5ml (Semi-Micro) Cuvettes for UV-Visible Optical SpectroscopyAll cuvettes have a 10mm path length and are 45mm high. Internal width of the semi-micro size is 4mm.
Tapered Fluoropolymer Caps for Bruker MATCH™ Tubes
The Bruker MATCH™ tube caps, specially machined from PTFE fluoropolymer, are color coded by tube size, and correspond to the color of the tube clamp in the MATCH™ Insert Assembly, allowing quick identification of matching components.
The MATCH™ tube cap incorporates a slightly tapered inner diameter. Initially, the cap aligns and pushes easily onto the tube. It then becomes progressively tighter as the tube reaches full depth within the cap, creating a positive seal to preserve volatile sample solutions throughout short or long term storage.
5mm Valved NMR Tubes for Intermediate Pressure, 1 Pack
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).
Select Series™ 5mm NMR Sample Tubes for Ceramic Turbines, 5 Pack
Our “Select Series™” NMR tubes are manufactured out of ASTM Type 1 Class A glass, commonly referred to as Pyrex® 7740 (Corning), Duran® (Schott Glass), or Kimax® KG-33 (Kimble) glass.
When working under variable temperature conditions, the tube diameter specifications narrow and tighten even more to take account of any slight thermal expansions or contractions in the ceramic turbine.
To meet this stringent diameter requirement, Norell has developed a line of NMR sample tubes, including both 5mm and 3mm O.D. sizes, that adhere to strict outside diameter specifications that are very tightly controlled.
Select Series™ 3mm, Ultra-Precision NMR Tubes, 5 Pack
Key properties that make this glass type desirable for NMR are its high degree of thermal shock resistance and low expansion coefficient. This allows for a greater margin of safety from breakage when used in variable temperature applications and freeze/thaw cycling, or under any other application where large temperature variations are required in the experiment.
Each NMR tube is checked for concentricity and camber specifications utilizing the latest computer technology.
Bruker Match System NMR Tubes, 5 Pack
Ultra-Precision, machined NMR tubes specifically made for the Bruker MATCH™ System.
5mm NMR Tube Septa, 100 Pack
These precision molded natural rubber septa for 5mm and 10mm NMR sample tubes seal against both the inner and outer surfaces of standard, thin wall NMR tubes, providing the ultimate protection for sensitive or reactive samples, isolating them from contact with air, moisture and other ambient contaminants.
This dual seal septum likewise protects personnel against exposure to samples that may pose health or safety hazards, while still allowing easy access through the septum, using a syringe, to add, transfer or retrieve samples from the NMR tube.
