Lab Bottles

Lab Bottles

Shop lab bottles for sample storage, reagent preparation and media handling in Australian laboratories. Compare PYREX and SIMAX glass laboratory bottles, including borosilicate media bottles, screw cap bottles and space-saving square designs.

Choose a bottle, neck size and closure

Select the capacity and opening to suit your application. The range includes GL45 screw cap bottles for routine filling and pouring, GL80 wide-mouth bottles, clear and amber-coated options, and replacement caps. Check each product listing for glass type, cap material, pack quantity and chemical compatibility.

Check glass and autoclave specifications

Borosilicate glass 3.3 offers resistance to thermal changes and many commonly used laboratory chemicals. Suitability depends on the chemical, concentration and temperature. Where specified for the selected screw cap bottle, an autoclave cycle of 121°C for 30 minutes may be used; follow the manufacturer’s instructions for the bottle, coating and closure rather than applying one cycle to every model.

Pair your bottles with lab beakers and glass measuring cylinders, or browse all laboratory glassware and laboratory equipment. View current discounts or contact our team for help with bottle selection, including DURAN enquiries.

FAQs

What is a borosilicate glass bottle, and why is it used in the lab?

A borosilicate glass bottle is a heat-resistant, chemically stable laboratory container used for storing, mixing and transporting samples. Its durability makes it ideal for demanding lab environments.

How do chemistry bottles differ from general-purpose bottles?

Chemistry bottles are designed for storing reagents, solvents and reactive solutions. They often feature specialised closures, tighter sealing or specific shapes compared to general-purpose bottles.

What are the chemical and thermal resistances of borosilicate glass bottles?

A borosilicate bottle offers excellent resistance to thermal shock and is compatible with most common acids, bases and solvents. It tolerates high temperatures and autoclaving without degrading.

Can I store aggressive reagents or solvents in borosilicate bottles?

Yes, many aggressive chemicals can be safely stored in borosilicate glass bottles, though strongly alkaline solutions, hydrofluoric acid and some concentrated reagents may require alternative materials like PTFE.

Are there compatibility issues when storing chemicals in glass vs plastic?

Some chemicals may permeate or degrade plastics, making borosilicate containers more suitable. Conversely, certain highly reactive or HF-containing solutions require plastic or PTFE instead of glass.

How do I choose between a borosilicate bottle and alternative materials like PTFE or plastic?

Choose a borosilicate glass bottle for general chemical storage, heating, autoclaving or when clarity is needed. Select PTFE for highly reactive or HF-containing substances and plastic for lightweight, impact-resistant storage.

What care and maintenance do borosilicate bottles require?

Clean with laboratory detergent, rinse thoroughly and avoid abrasive scrubbing. Inspect regularly for chips or cracks, as damage can compromise its integrity.

What is the lifespan of a glass laboratory bottle, and when should it be replaced?

A glass laboratory bottle can last for years with proper care. Replace it immediately if you notice cracks, chips, clouding or compromised closures.
