Glass Reagent Bottle With Screw Cap

Product Code : SCL-LG-11998

Glass Reagent Bottle With Screw Cap (SKU SCL-LG-11998) is a 250 mL graduated Borosilicate 3.3 glass bottle closed by a blue polypropylene GL45 screw cap with a drip-free pouring ring, used to prepare, store and carry reagents, solutions and culture media. Chemistry and microbiology laboratories in schools, colleges and testing centres rely on this type of media bottle. Science Lab Supplies supplies it from Ambala, India to institutions, tender contractors and distributors.

Specifications

The clear body is Borosilicate 3.3 glass with a white enamel graduation scale and a large marking spot for labelling. The GL45 polypropylene cap screws down to limit evaporation and contamination, and the matching pouring ring stops drips running down the outside when solutions are dispensed.

Applications and Experiments for the Glass Reagent Bottle With Screw Cap

A screw-cap reagent bottle keeps prepared solutions sealed and labelled on the shelf, and because it can be autoclaved it also serves for making and holding sterile media. The 250 mL size suits bench stocks of reagents, indicator solutions and small batches of media.

• School and college chemistry: storing prepared acids, alkalis and standard solutions.
• B.Sc. microbiology: preparing and autoclaving nutrient media.
• Environmental science: collecting and carrying water samples to the laboratory.
• Quality-control laboratories: labelled stock and working solutions.

Never heat or autoclave the bottle with the cap screwed tight; pressure build-up can burst the glass. Loosen the cap first.

Standard Scope of Supply

A pack contains six 250 mL glass reagent bottles, six blue GL45 polypropylene screw caps, six drip-free pouring rings and one laboratory chemical storage guidelines manual. Reagents and media are not included; other bottle types can be added to the same quotation.

Frequently Asked Questions

What is a glass reagent bottle with screw cap used for?
It stores, mixes and transports liquid reagents, solutions and culture media. The screw cap keeps out dust and limits evaporation, and the pouring ring gives clean, drip-free dispensing.

Can the bottle and cap be autoclaved?
Yes, the listing states both can be steam-sterilised, typically at 121°C. Always loosen the cap before autoclaving so steam can circulate and pressure can equalise.

What comes in one pack?
Six 250 mL bottles, six blue GL45 caps, six pouring rings and a chemical storage guidelines manual.

Who supplies the Glass Reagent Bottle With Screw Cap?
Science Lab Supplies supplies it from Ambala, India. Schools, colleges, testing laboratories and contractors can order packs alone or with other storage and volumetric glassware.

Related Storage and Preparation Glassware

Solutions are made up in one vessel, stored in another and dispensed in small amounts from a third. These four items cover preparation, storage and dispensing alongside the screw-cap bottle, so a laboratory can equip its reagent shelf from a single enquiry.

• Reagent Bottles Narrow-Mouth — stoppered storage for liquid reagents.
• Dropping Bottle — dispenses indicators and reagents drop by drop.
• Volumetric Flask — makes up standard solutions before storage.
• Borosilicate Beaker — for mixing and dissolving before bottling.
