The Premium Borosilicate Glass Vacuum Take-Off and Gas Inlet Adapter is an essential connecting component designed for advanced laboratory setups. Whether performing organic synthesis, complex vacuum distillation, fractional distillation, or solvent reflux, these adapters provide a highly reliable pathway for gas introduction, vacuum evacuation, or inert gas purging.

Each adapter features a serrated hose connection (nozzle) optimized for secure tubing attachment, and a precision-ground joint section. The Bent with Hooks (Double Ears) models are specifically designed to allow the use of springs or joint clips to lock the connection in place under positive pressure or high vacuum, ensuring maximum safety.

These adapters are highly compatible and commonly paired with thermometers, Liebig/Graham condensers, stirring shafts, and separatory funnels to assemble high-efficiency chemical apparatus.

Features

High Transparency & Clarity: Manufactured from premium optical-grade borosilicate glass, offering exceptional clarity and transparency. This allows researchers to easily monitor gas flow, vapor condensation, or any reaction transitions inside the tube.

Standard Ground Joints: Features high-precision, standard tapered ground joints (14/23, 19/26, 24/29, 29/32). Each joint is meticulously frosted to ensure a perfectly tight, leak-proof seal with matching laboratory glassware, preventing vacuum loss.

Premium Heavy-Wall Glass: Constructed from thickened, high-strength borosilicate glass 3.3. It exhibits superb resistance to high temperatures, thermal shock, and aggressive chemical corrosion, making it highly durable under pressure or deep vacuum conditions.

Flexible Hook Options: Available in straight and bent configurations, with or without double glass hooks (ears) for securing joint connections with springs or retaining clips.
