Reagent Bottle
Product Code : SCL-CLE-11925
The StemAids Reagent Bottle is a precision-molded laboratory vessel designed for the secure storage of liquid and powdered chemicals. Unlike screw-cap media bottles, this classic variant features a precision-ground glass stopper, providing an all-glass environment that is essential for reagents that may react with or leach plasticizers from polymer caps. Manufactured to ISO 4796-2 standards, these bottles are available in clear and amber glass to ensure the long-term stability of standardized analytical solutions.

Key Pedagogical & Laboratory Outcomes
- Actinic Interface: Facilitates student understanding of Photolysis. Using Amber bottles, learners identify how specific wavelengths of light are filtered to prevent the decomposition of sensitive chemicals like Silver Nitrate (AgNO3) or Hydrogen Peroxide (H2O2).
- Contamination Analysis: Supports high-purity Quantitative Analysis; learners evaluate why an all-glass seal is preferred for reagents that must remain free of organic contaminants (plasticizers).
- Vapor Containment: The precision-ground joint provides a high-integrity seal; students apply these bottles to store volatile or odorous reagents, significantly reducing ambient laboratory fumes.
- Solid Phase Management: In the Wide Mouth configuration, students analyze the ease of transfer for crystalline and powdered solids, ensuring quantitative recovery without residue trapped in the neck.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade, high-density packaging. To prevent the common issue of "stuck stoppers," every bottle is shipped with a protective insert between the stopper and the neck, then nested in shock-absorbent partitions.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and glass composition certifications.
- Durability: The Borosilicate 3.3 models are annealed to eliminate internal stresses, ensuring the neck—the most vulnerable part of the bottle—is resistant to mechanical impact.
Direct OEM Sourcing Advantages
Procuring StemAids Reagent Bottles directly ensures vertical manufacturing control:
- Hermetic Ground Joints: Direct oversight of the diamond-grinding process ensures that the stopper and neck are perfectly matched for a leak-proof, air-tight seal without requiring lubrication.
- Uniform Actinic Coating: For Amber models, we ensure the iron-oxide coloration is consistent throughout the glass melt, providing 100\text{%} reliable UV protection.
- Direct Factory Inventory: Guaranteed availability of matching replacement stoppers, preventing the decommissioning of bottles due to a lost or broken cap.
- Quality Assurance: Every batch is "alkali-leach tested" to ensure the glass surface does not alter the pH of stored sensitive standard solutions.
