- PROFESSIONAL AIR-FREE CHEMISTRY – Designed for manipulating air-sensitive compounds (Grignard reagents, organometallics) using standard Schlenk line techniques. The integrated High Vacuum Valve allows for precise evacuation and backfilling with inert gases (Nitrogen or Argon) to create a strictly oxygen-free environment.
- SECURE VACUUM SEAL & HOSE CONNECTION – Features a specialized glass sidearm specifically designed for 0–4mm valve models. The sidearm has an 8mm (5/16") O.D. serrated hose barb. REQUIRED FIT: You must use 1/4" (6mm) Inner Diameter vacuum tubing to ensure a leak-proof seal during high-vacuum cycles.
- PREMIUM BOROSILICATE GLASS 3.3 – Crafted from heavy-wall, low-expansion Borosilicate glass. This vessel is optically clear, flame-resistant, and thermally stable, capable of withstanding the thermal shock of direct heating or rapid cooling (e.g., dry ice baths) without breakage.
- PRECISION HIGH VACUUM VALVE – Equipped with a chemically resistant PTFE valve stem (0–4mm bore) with ease-of-turn handle and double O-ring seals. This ensures a vacuum-tight closure down to 10^-4 Torr range, effectively isolating reactive contents from the atmosphere.
- VERSATILE LAB APPLICATION – Ideal for use with vacuum manifolds, gloveboxes, and nitrogen lines. The 250mL round bottom design withstands positive pressures better than flat bottoms, making it the standard choice for synthesis, crystallization, and storage of hygroscopic materials.
