GPS-LAB-4390 / Laboratory & Chemical
Borosilicate or soda-lime reagent bottles with a wide mouth and a ground-glass or screw stopper, for storing solids, pastes, crystals and viscous reagents that a narrow neck cannot easily admit. Available in clear and amber for light-sensitive chemicals.
Specification
Product Knowledge
Background, typical uses, construction, filling guidance and production notes for buyers selecting this container for bulk supply or private-label programs.
Reagent bottles are the standard glass containers for storing laboratory chemicals, and the wide-mouth version exists for everything that will not pour or pipette through a narrow neck — solids, crystals, powders, pastes and thick reagents that have to be scooped or spooned in and out.
They come with a ground-glass stopper, a precision-fit glass plug that seals against the matching ground neck, or a screw cap. Amber glass is offered for chemicals that degrade in light.
Storing solid and crystalline reagents, pastes and viscous chemicals, powders and granules, and light-sensitive reagents (in amber). Used in stockrooms, dispensing, teaching labs, specimen storage and industrial QC.
A wide-mouth body in borosilicate 3.3 (for chemical and thermal resistance) or laboratory soda-lime (for general storage), with either a ground-glass stopper joint or a GL screw thread. Ground stoppers are matched to their bottle; screw caps use chemically resistant PP with a PTFE or PE liner. Amber glass blocks light for sensitive contents.
Ground-glass stoppers and necks are matched pairs and should be kept together; a light film of the right grease can prevent seizing with caustic or certain reagents, though it must not contaminate the contents. Choose borosilicate for reactive or temperature-cycled chemicals and amber for light-sensitive ones. Reagent bottles are for storage, not accurate measurement.
Borosilicate bottles are formed from a low-expansion melt; the wide mouth and (for stoppered versions) the ground joint are produced and then precision-ground to a matched fit with the stopper. Annealed for stress relief, with amber from batch chemistry. Joint fit and chemical-grade glass are the key checks.
Build Options
A packaging program is more than the glass. Closure, liner, fill process, label area and export carton should be confirmed together before the first sample or bulk order.
Confirm brimful capacity, practical fill level, body proportions and label panel so the chosen size suits the product and the line.
Match lug, CT, cork, pump or dispensing closures with the right liner for the fill temperature, viscosity and sealing method.
Clear or amber glass, sprayed color, frosting, embossing and decoration are checked against shelf presentation and light protection.
Carton partitions, pallet pattern, loading plan and shipping marks are planned for long-distance transport and warehouse handling.
Applications
Share filling temperature, product acidity, viscosity and shelf-life target so we can check the container, closure liner and packing method before quotation.
Review available molds first, then evaluate color, decoration or a mold change if the project needs a differentiated retail look.
Confirm capacity, closure fit, liner selection, label area and carton protection with samples before bulk production.
Cartons, dividers, pallet loading and shipping marks are planned for distributors, warehouses and multi-country shipments.
Bulk Quote
Send capacity, quantity, closure, decoration and destination details. We will return practical MOQ guidance, sample options and export packing recommendations.
