Background, typical uses and selection points for this product. We can send model drawings, technical data and samples to support your evaluation.
Reagent bottles are the standard glass containers for storing laboratory chemicals, and the wide-mouth version is built for everything that won’t pour through a narrow neck: solids, crystals, powders, pastes and thick reagents that need to be scooped or spooned in and out.
We supply them with a matched ground-glass stopper or a screw cap, in clear glass or in amber for chemicals that degrade in light.
Wide-mouth reagent bottles hold solid and crystalline reagents, powders and granules, pastes and viscous chemicals, and, in amber, light-sensitive materials. Chemical stockrooms use them for bulk solids that are weighed out daily; teaching labs use them for student reagent sets; industrial QC labs use them for retained samples and reference materials. The wide opening also makes them practical for specimen and sample storage where contents are removed with a spatula or tongs.
The body is offered in borosilicate 3.3 for chemical and thermal resistance, or in laboratory soda-lime glass for general storage. Stoppered versions have a ground-glass neck matched to a glass stopper; screw versions have a GL thread and a chemically resistant polypropylene cap with a PTFE or PE liner. Amber glass screens out much of the light that breaks down sensitive reagents, and a marking spot on the body takes handwritten labels. As storage bottles, they carry no volume scale.
Keep each ground-glass stopper with its own bottle, because stopper and neck are ground as a matched pair. With caustic or crystallizing reagents, a thin film of suitable grease helps prevent seizing, provided it can’t contaminate the contents. Choose borosilicate for reactive chemicals or bottles that go through repeated washing, and amber for anything light-sensitive. Tell us what you plan to store and we’ll recommend the glass, closure and liner.
We form the bottles from borosilicate or laboratory soda-lime glass, anneal them for stress relief, and precision-grind stoppered necks to a matched fit with their stoppers. Amber color comes from the glass batch itself, not a coating. Options include printed hazard or brand labels, color-coded caps, and packing in counts for stockroom distribution. Samples from stock sizes are available before a bulk order.
Customization
We specify the container, closure, decoration and transit packing as one package, so every part fits and arrives ready for your filling line.
Choose from standard sizes or request a custom capacity. We supply drawings with tolerances, label panel dimensions and nominal and brimful capacity.
We match caps, liners, pumps, droppers and stoppers to the neck finish and check the seal against your contents and filling process.
Flint, amber and colored glass, with frosting, spray coating, screen printing, hot stamping or labels. Material documentation is available on request.
Partitioned cartons, layer pads or bulk pallets, with shipping marks and pallet patterns planned for your route and warehouse.
Applications
Typical markets and uses. Tell us your contents, filling process and storage conditions and we will recommend the right model and components.
We confirm availability of the standard model, and review any changes to size, color, decoration or tooling for feasibility and lead time.
We send samples and specification sheets so you can check dimensions, component fit and finish before you place the order.
Your quotation covers packing design, shipping route, Incoterms and export documents, so landed cost is clear from the start.
