Precision Sealing for Laboratory Applications

These hollow glass stoppers, with their smooth, ground surfaces, create airtight seals that minimize contamination and evaporation. Their compatibility with a wide range of standard lab glass bottles, burettes, and flasks makes them essential for secure sample handling in both academic and industrial laboratories.

Resilient and Customizable Design

Engineered with high-quality borosilicate glass, these stoppers offer outstanding resistance to thermal shock, corrosion, and aggressive chemicals. You can specify custom sizes in addition to standard diameters, ensuring optimal fit for specialized uses and equipment requirements.

FAQ's of glass Hallow stopper:

Q: How are glass hollow stoppers typically used in laboratory settings?

A: Glass hollow stoppers are primarily used to securely seal laboratory glassware such as bottles, flasks, and burettes, ensuring airtight conditions for sample storage or reaction containment. Their chemical and temperature resistance makes them suitable for a wide variety of protocols involving acids, alkalis, and other reagents.

Q: What are the benefits of using borosilicate glass hollow stoppers over other materials?

A: Borosilicate glass offers excellent thermal and chemical resistance, providing durability against acids, alkalis, and solvents. Additionally, it can withstand temperatures up to 400C, reduces the risk of contamination due to its non-reactive surface, and is reusable for multiple laboratory cycles.

Q: When should a laboratory choose hollow stoppers instead of solid ones?

A: Hollow stoppers are preferred when pressure equalization or reducing material mass is necessary, or for certain processes requiring less thermal inertia. They are also suited to applications where minimizing the risk of stopper breakage and ensuring ease of handling are priorities.

Q: Where can these hollow glass stoppers be sourced for laboratory use?

A: These stoppers are available from laboratory equipment distributors, exporters, manufacturers, and suppliers across India, and can be ordered in both standard and custom sizes to fit specific application needs.

Q: What is the process for proper cleaning and sterilization of these stoppers?

A: To clean and sterilize glass hollow stoppers, wash thoroughly with laboratory-grade detergents, rinse with deionized water, and sterilize by autoclaving at appropriate temperatures. Their borosilicate composition ensures they can withstand multiple autoclave cycles without compromising quality.

Q: Are these stoppers compatible with non-borosilicate lab glassware?

A: Yes, these hollow stoppers fit most standard laboratory glassware, including both borosilicate and soda lime glass bottles and flasks, as long as the neck diameter matches the stopper size selected.
