Glass Reagent Bottles with GL45 Screw Cap

Glass Reagent Bottles with GL45 Screw Cap

Borosilicate glass reagent bottles with blue GL45 polypropylene screw cap and drip-free pouring ring, designed for laboratory reagent storage, media preparation, buffer mixing, sample archiving, and general liquid or powder containment. The wide-mouth GL45 threaded neck provides convenient access for pipetting, pouring, and cleaning, and is compatible with standard GL45 filtration assemblies and bottle-top dispensers. Each bottle features permanent white enamel graduation markings and a large white labeling patch for easy sample identification. The autoclavable PP cap with integrated pouring ring provides a leak-proof, airtight seal and can withstand sterilization at up to 140deg C. Clear bottles allow direct visual inspection of contents; amber bottles block UV and visible light to protect photosensitive reagents, light-sensitive media, and biological solutions. Available sizes from 25 mL to 1000 mL. Reusable and compatible with standard laboratory cleaning and autoclaving protocols.

COMMON APPLICATIONS: Reagent and buffer storage; cell culture media preparation and storage; chromatography solvent storage; light-sensitive solution containment (amber); environmental and biological sample archiving; autoclave-compatible liquid sterilization.

USAGE NOTES: Cap should be tightened firmly by hand – do not overtighten. The GL45 thread is compatible with standard bottle-top filters, dispensers, and cap assemblies from major suppliers. Autoclave with cap loosened slightly to allow pressure equalization. After autoclaving, tighten cap immediately upon removal to maintain sterility. Clean with standard laboratory detergent and rinse thoroughly. Not recommended for hydrofluoric acid or highly concentrated alkali solutions.
