These precision-drawn borosilicate glass pipettes are specifically engineered for NMR sample handling, featuring extended tips that reach the bottom of 203mm (8”) NMR tubes while maintaining optimal sample transfer control.
Glass Specifications
Manufactured from USP Type I and ASTM E438 Type I Class B borosilicate glass, providing superior chemical resistance and minimal extractable contamination. The low thermal expansion coefficient ensures excellent thermal shock resistance for temperature-sensitive applications.
Compatibility
• 5mm NMR tubes (all lengths): including medium wall tubes up to 0.8mm thickness
• 3mm NMR tubes: 178mm (7”) length with walls up to 0.38mm (Select Series and Sample Vault Series)
• Universal compatibility with standard rubber bulbs and pipetting devices
Technical Specifications
• Total volume capacity: 2.5ml (providing ample headspace for typical 1ml NMR sample volumes)
• Body diameter: 7mm O.D. for standard laboratory pipetting device compatibility
• Tip design: uniformly drawn for precise sample access and transfer
Key Benefits
The extended tip length and precision bore design enable accurate sample placement and retrieval from deep NMR tubes while the high-purity glass construction prevents sample contamination in sensitive analytical applications.
