Pyur Scientific Glass Reagent Media Storage Bottle - 250 mL - GL45 Screw Cap - Graduated

Graduated Glass Storage for Solutions - 250 mL

Mixing stock solutions, calibration fluids and test samples is messy when your container leaks, clouds or lacks volume marks. This Pyur Scientific reagent bottle uses thick borosilicate glass, a graduated body and a GL45 screw cap, so you can store, check and pour a solution from one container.

At 250 mL, this size suits hobbyists, small indoor growers and anyone who wants a handy bottle for small batches, sample retention or a trial run. Larger cultivation operations can pair several bottles to keep different solutions separate.

Key Features & Benefits

• Thick borosilicate glass — a durable, stable container that suits laboratory-style use.
• Graduated markings — lets you check liquid volume without a separate measuring vessel.
• GL45 screw cap — closes the bottle to help prevent leaks during storage.
• Threaded screw neck — designed to reduce spilling while you pour.
• 250 mL capacity — a compact size for small batches and samples.

Who Should Use Pyur Scientific Glass Reagent Media Storage Bottle

Home gardeners and commercial growers who store nutrient stocks, pH adjusters, reference solutions or water samples will find this bottle useful, as will anyone who needs a lab-style container for general storage.

Frequently Asked Questions

Q: What does GL45 mean?
A: GL45 is a standard thread size for the bottle neck and cap. It describes how the cap fits the neck, so the closure screws on securely.

Q: Is the bottle marked for measuring?
A: Yes, the bottle is graduated, so you can read approximate volume on the side. The capacity is 250 mL.

Q: Why choose borosilicate glass over plastic?
A: Borosilicate glass is a thick, stable material that suits laboratory-style storage. Many growers choose glass when they want a rigid, reusable container for solutions.

Q: Will the cap prevent leaks?
A: The GL45 screw cap is designed to seal the bottle and help prevent leaks. Tighten it fully before storing or moving the bottle.

Q: Can I store things other than lab reagents?
A: Yes, the bottle is laboratory grade but suits general storage. Check that your contents are compatible with glass and the cap material first.
