Reagent Bottle W/M

Key Product Features

• Extra-Wide Opening: The large diameter of the neck facilitates effortless filling and complete emptying of the bottle. It is especially useful for dense powders or “sludge-like” substances that would clog a narrow neck.

• Borosilicate 3.3 Glass: Offers the highest level of chemical durability and thermal shock resistance. It is virtually inert, ensuring that the purity of your dry reagents is not compromised by leaching.

• Ground-Glass Joint & Stopper: Features a precision-frosted neck and an interchangeable ground-glass stopper. This creates a high-performance seal to keep moisture out, preventing hygroscopic powders (like CaCl2​ or $NaOH$ pellets) from clumping or degrading.

• Clear Visibility: High-clarity glass allows for the easy inspection of contents, color changes, or crystallization without opening the bottle.

• Sterilizable: Both the bottle and stopper are fully autoclave-safe, making them ideal for the preparation and storage of solid culture media (agar) in microbiology.

Technical Specifications

Primary Applications

• Dry Chemical Storage: Ideal for salts, crystalline reagents, and metal shavings.

• Viscous Substance Handling: Used for oils, pastes, and concentrated syrups that are difficult to pour through narrow openings.

• Sample Collection: Widely used in environmental field-testing for soil or sediment samples where a wide mouth is required for easy deposit.

• Amber Variants: Available in Amber Glass for light-sensitive solids (e.g., Iodine crystals or certain pharmaceutical powders) to prevent photo-degradation.Maintenance & Safety

• Stopper Care: To prevent the glass stopper from “freezing” (becoming stuck) due to fine powder particles or alkaline residues, ensure the joint is wiped clean before sealing. For long-term storage of reactive solids, a thin PTFE (Teflon) sleeve can be placed over the stopper.

• Thermal Use: While the bottle is made of Boro 3.3, it should not be subjected to extreme localized heating (like a direct flame). It is designed for storage and low-temperature incubation.

• Cleaning: The wide mouth makes these bottles much easier to clean with a standard laboratory brush compared to narrow-mouth versions, as you can easily reach the bottom “corners” of the bottle.

Why Choose Wide Mouth (W/M)?

The Wide Mouth Reagent Bottle is the essential choice for any laboratory dealing with solid-state chemistry. It eliminates the frustration of trying to shake powders out of a narrow neck and ensures that you can retrieve 100% of your reagent with a spatula, minimizing waste and maintaining a cleaner workspace.
