Storage tube with high vacuum valve and side-arm straight outer joint. This design allows a Schlenk tube to be sealed more completely than a standard Schlenk flask .the tube O.D. is 28mm, the tube length is 120mm.Laboy glass flasks are heavy wall designed, made by hand-blowing to ensure uniform wall thickness, made of high-quality borosilicate glass and annealed at 800 degree Celsius, can be heated directly in an open flame and can withstand typical laboratory thermal variations in Chemistry processes like heating and cooling.

  • PREMIUM SCHLENK TUBE FOR AIR-SENSITIVE WORK – Engineered specifically for the manipulation of air-sensitive and moisture-sensitive compounds. The 28x120mm cylindrical geometry is optimized for Freeze-Pump-Thaw cycles, Cryogenic Trapping, and saving valuable bench space.
  • PRECISION 0-4mm HIGH VACUUM VALVE – Features a hand-ground, smooth-action control valve. This allows for fine-tuning of inert gas flow (Nitrogen/Argon) and creates a dependable, leak-proof seal capable of maintaining high vacuum for extended storage of volatile reagents.
  • 14/20 GROUND GLASS SIDE ARM (SUPERIOR SEALING) – Features a 14/20 Standard Taper Joint on the side arm instead of a hose barb. This ensures a chemically resistant, all-glass connection to vacuum manifolds (requires adapter or matching glass line), eliminating contamination risks from rubber tubing.
  • HEAVY-WALL BOROSILICATE 3.3 GLASS – Constructed with extra-thick walls to withstand the mechanical stress of vacuum cycling and thermal shock. The robust design makes it safe for use with oil baths, heating mantles, and direct immersion in liquid nitrogen dewars.
  • PROFESSIONAL SPECS – Capacity: 50mL | Dimensions: 28mm O.D. x 120mm High | Main Joint: 14/20 | Valve: 0-4mm. Ideal for solvent drying, crystallization, and small-batch synthesis.
