Adapters Recovery Bend Sloping End

OVERVIEW :

A GWSI Adapter Recovery Bend with a Sloping End is the angled connector that carries distilled vapor or condensate from your still head into a receiving flask. It’s blown from premium borosilicate 3.3 glass, so it resists aggressive solvents, resists water attack, and handles sharp temperature swings without cracking. The gentle slope keeps droplets flowing cleanly downward, preventing pooling and backflow while staying fully

HISTORY :

Recovery bends grew out of the early distillation glassware of the 18th–19th centuries, when chemists first needed a compact angled joint to drop condensed vapour neatly into a receiver. The sloping-end design made draining smoother and reduced the “wet wall” that trapped product in straight adapters.

APPLICATIONS :

– Pharmaceutical labs — guiding distillate into receiving flasks with minimal product loss.

– Biotech / analytical setups — connecting still heads to condensers or collection vessels in vacuum runs.

– Industrial chemical recovery — routing solvent and purified fractions safely between apparatus.

MANUFACTURING PROCESS :

GWSI melts high-purity borosilicate 3.3 glass and forms each recovery bend by master hand blowing to keep the curve smooth and the walls even. A careful annealing pass then removes internal thermal stress, giving the bend long-lasting resistance to cracking under hot solvents.

TESTING PROCESS :

Each recovery bend is examined under a polariscope to confirm zero residual strain around the bend and joints.

PACKAGING PROCESS :

Finished bends undergo a final cosmetic sort to remove any chips, bubbles, or flaws before packing. Approved pieces ship in heavy-duty double-wall cartons with shock-absorbing bubble wrap, built to protect the angled glass through export transit.

MAINTENANCE & SAFETY :

– Clean: Rinse with acetone and mild detergent plus deionized water; never use wire brushes or abrasive pads on the ground joints.

– Autoclave safely: Steam at 121°C (15 psi) — this autoclavable lab glass handles it; cool slowly to prevent thermal shock.

– Store: Lay it padded in a compartmented tray, keeping the sloping arm and joint faces clear of contact with other glass.
