- Syringes
- Luer-lock polypropylene, 1mL and 3mL, sterile single-use
- Luer-lock polypropylene with printed graduation marks certified to ±2% accuracy
- Research syringes lack volumetric certification
- Clinical syringes are required for dose-critical studies where ±0.05mL variance affects outcomes
- Reconstitution Needles
- 25-gauge, 1.5-inch, standard bevel
- 25-gauge, 1.5-inch, sterile-filtered, siliconised
- Siliconisation reduces friction and septum coring
- Clinical needles reduce particulate contamination by 60% in multi-draw protocols
- Administration Needles
- 29-gauge or 30-gauge insulin syringes
- 29-gauge or 30-gauge insulin syringes with ultra-thin wall technology
- Wall thickness affects flow rate and injection pain
- Ultra-thin wall needles deliver 15% faster with 30% less tissue trauma
- Bacteriostatic Water
- USP-grade with 0.9% benzyl alcohol
- USP-grade, nitrogen-purged, oxygen <2 mg/L
- Oxygen content during storage
- Nitrogen-purged water extends NAD+ stability from 14 days to 28 days post-reconstitution
- Vial Stoppers
- Standard grey butyl rubber
- Teflon-coated butyl rubber
- Coating prevents rubber particle shedding
- Teflon-coated stoppers eliminate the 12–18 rubber fragments per 20-gauge puncture found in standard stoppers
- Storage Vials
- Clear borosilicate glass
- Amber borosilicate glass, Type I
- Light transmission
- Amber vials block 99.8% of UV and visible light wavelengths that degrade NAD+
