Borosilicate Glass Aspirator Bottles
Goel Glass manufactures heavy-duty Borosilicate Glass Aspirator Bottles designed for clean liquid dispensing, solvent storage, buffer reservoir management, and gravity liquid transfer in laboratory, pharmaceutical, and pilot-scale industrial environments. Fabricated with substantial wall cross-sections and heavy-duty base rims, each bottle undergoes complete thermal annealing in accordance with ISO standards to ensure long-term mechanical reliability and resistance to thermal shock.
We supply two standardized configurations tailored to your dispensing needs: the Aspirator Bottles with Outlet for Stopper with a smooth tubulation for elastomeric stopper/hose connections, and the Aspirator Bottles with Interchangeable Stopper & Stopcock equipped with precision interchangeable ground joints and a stopcock for fine flow metering.

Design & Material Benefits
- Chemical Compatibility: High resistance to attack by strong acids, halogens, and aggressive organic solvents.
- Heavy Base Stability: Low center of gravity with reinforced flat base prevents accidental tipping during high-volume fill operations.
- Autoclavable Reliability: Safe for repeated steam sterilization at 121°C (250°F) without structural degradation.
- Interchangeable Ground Joints: Precision CNC-ground standard tapers per ISO 383 ensure hermetic, leak-free seals with stopcocks and stoppers.
Frequently Asked Questions
The Aspirator Bottles with Outlet for Stopper features plain tubulated top and bottom necks, designed to accommodate standard rubber or silicone stoppers and direct tubing push-connections. The Aspirator Bottles with Interchangeable Stopper & Stopcock features ground glass sockets (45/40 or 55/44 neck socket and 29/32 outlet socket) supplied with an interchangeable ground glass stopper and a precision stopcock valve for controlled gravity dispensing.
Yes. Made from Borosilicate Glass, our aspirator bottles withstand repeated autoclave cycles at 121°C and 134°C. When autoclaving with stoppers or stopcocks fitted, ensure closures are loose or vented to prevent internal pressure buildup.
Yes. Because all joints conform strictly to ISO 383 standard interchangeable ground joint taper ratios (1:10), replacement glass stoppers, PTFE stopcock keys, and matching adapters are interchangeable and readily stocked for immediate dispatch.
