Among laboratory utensils, wide mouth reagent bottles, with their wide openings and exceptional practicality, play an irreplaceable role as both "warehouse managers" and "operating platforms." Wide-mouth bottles naturally suit solid powders and viscous liquids. They enable convenient, rapid sample access. Their unique design solves specific limitations of narrow and medium-mouth bottles.
Unlike Medium mouth glass reagent bottles and Narrow Mouth Reagent Bottles, the core design concept of the wide-mouth reagent bottle is "openness and accessibility." Its most striking feature is a mouth diameter that closely matches the diameter of the bottle body, creating a spacious, open entrance. The wide-mouth bottle works perfectly with spoons, spatulas, or direct pouring. It delivers an unmatched user-friendly experience. This significantly boosts laboratory efficiency.
The practical performance of the wide-mouth bottle is also inseparable from its sturdy material and sophisticated manufacturing technology.
The wide mouth reagent bottle is made of 3.3 high borosilicate glass, the same source as all high-end laboratory vessels, ensuring its reliability in a wide range of applications.
Good heat resistance enables high-pressure sterilization. This meets sterile operation requirements. Excellent chemical inertness resists water, acids, alkalis, and various chemicals. This protects stored solids and liquids from contamination. These properties make it ideal for moisture-sensitive or high-purity powders.
High mechanical strength: The wide bottom design provides stable support, and the high hardness of the glass itself enables it to withstand the collisions and friction in daily use and has a long life.
Reagent bottle screw cap: Also made of high-quality polypropylene. PP is chemically stable, and its excellent toughness and resistance to stress cracking ensure that the wide cap fits snugly against the bottle opening even with frequent openings.
Gasket of reagent bottle：Each cap contains a built-in PTFE gasket. PTFE provides absolute chemical inertness and minimal adsorption. This effectively contains vapors from volatile solids. It also blocks external moisture absorption. The gasket ensures a fully inert sealed environment.
Material Combination：The classic trio includes borosilicate glass, PP cap, and PTFE gasket. This combination creates strong, inert, and sealed properties. These features allow easy handling of solids and viscous reagents. The system simultaneously delivers reliable protection.
This is the core advantage of the wide-mouth bottle. Its wide mouth makes it possible to:
Solid reagents can be easily taken in and out: There is no obstacle when using tools such as medicine spoons and spatulas to hold or take out powders, granules, and crystals without causing dust to fly or spill.
Smooth transfer of viscous liquids: For high-viscosity liquids such as glycerol, culture medium, agarose or certain oils, wide-mouth bottles allow the use of tools such as glass rods and spatulas for scraping and transfer, avoiding the embarrassment of pouring and cleaning in narrow-mouth bottles.
Direct sampling: Experimenters can even conveniently reach directly into the sampler or take it with their hands (where safety regulations permit), which is unmatched by other bottle types.
Wide-mouth bottles are undoubtedly the easiest type of reagent bottles to clean. The straight or slightly curved interior design allows complete brush access. Cleaning fluids rinse all surfaces without obstruction. This thorough cleaning process minimizes cross-contamination risks. These features make the bottles ideal for frequent content changes. They are equally suitable for repeated bottle reuse applications.
The bottles feature a wide, flat base. This ensures secure stacking in storage areas. It maximizes space efficiency in laboratories.
The broad surface offers excellent labeling space. This enables clear identification and record-keeping. It enhances laboratory organization and workflow.
These bottles function beyond basic storage. They serve as temporary reaction vessels. They work as sample mixing containers. They can even substitute small Petri dishes.
The wide opening supports various operations like stirring and grinding. This multifunctional design provides exceptional flexibility.
Wide-mouth glass reagent bottles are the absolute mainstay in the following scenarios:
Storage of solid chemical reagents: such as inorganic salts, powdered compounds, reference substances, desiccants (such as silica gel), etc.
Biological and microbiological laboratories: used to hold culture media (especially agar culture media), bacterial plates, yeast extracts, etc.
Food and pharmaceutical analysis: Storage of powder samples, tablet grinds, viscous extracts, etc.
Materials Science: Contains small parts, powder materials, adhesives, etc.
Educational Demonstrations: Ideal containers for displaying samples such as crystals, seeds, and mineral specimens in classroom demonstrations.
Our wide-mouth bottles offer complete capacity choices. Available sizes include 25ml and 75ml small bottles. Standard options feature 125ml and 350ml sizes. Larger containers provide 500ml, 750ml, 1000ml, and 1200ml capacities. This complete range serves all applications from routine sampling to bulk material storage.
Transparent Bottles
These bottles accommodate most light-stable solids and liquids. They deliver excellent visibility for examining contents. Users can conveniently check material form, color, and remaining amount.
Amber Bottles
Manufactured from special UV-blocking glass (290-450nm). They ensure dependable light protection for photosensitive materials. These include various vitamin powders, light-sensitive chemicals, and photographic substances.
With scale: Some models have permanent capacity scale lines sprayed by high temperature on the bottle body, which is convenient for quick estimation of volume when used as a liquid container.
High-purity grade: After special cleaning and processing, it ensures extremely low metal ion background value, meeting the field of trace analysis and other fields with extremely high purity requirements.
Wide-mouth bottles represent laboratory pragmatism. They don't suit highly volatile reagents. Their convenience, cleanability, and capacity excel. These qualities enhance experimental efficiency. They optimize workflow processes effectively. Choosing our wide-mouth glass reagent bottles means you've chosen a dedicated, hardworking, and open-minded assistant for your laboratory.
