Special Features

  • HIGH VACUUM PRECISION VALVE: Features a chemically resistant 0-4mm adjustable valve with O-ring seals. Delivers ultra-low leak rates ($10^{-3}$ Torr) for Schlenk lines and allows fine gas flow control to prevent powder bumping during evacuation.
  • GREASE-FREE OPERATION: The advanced valve design eliminates the need for vacuum grease, preventing sample contamination and completely solving the "frozen joint" issues common with traditional glass stopcocks.
  • OPTIMIZED PEAR-SHAPE: The tapered Kjeldahl-style bottom concentrates solid residues for efficient recovery and maximizes magnetic stirring performance, superior to standard round-bottom flasks for crystallization and drying.
  • HEAVY WALL BOROSILICATE 3.3: Manufactured from thick-walled glass adhering to ASTM E438 standards. Designed to safely withstand high vacuum pressure and thermal shock during direct flame heating.
  • STANDARD 19/22 JOINT: Precision-ground outer joint connects seamlessly to manifolds, condensers, and stoppers, ensuring an airtight seal for sensitive organometallic synthesis.
