Dropping Bottle
Product Code : SCL-CLE-11898
The StemAids Dropping Bottle is a specialized laboratory vessel engineered for the controlled, drop-wise delivery of reagents, stains, and indicator solutions. Available in both clear and amber glass, these bottles are designed to protect light-sensitive chemicals while providing an airtight seal to prevent evaporation. Manufactured to ISO 9001:2015 standards, they are essential for University and Clinical laboratories where precise, small-volume titration or slide staining is required.

Key Pedagogical & Laboratory Outcomes
- Volumetric Interface: Facilitates student understanding of Drop-Wise Titration. The dropper allows for the addition of reagents "one drop at a time," ensuring the exact endpoint of a reaction is captured without overshooting.
- Storage Quantification: Enables the preservation of unstable reagents; the Amber Glass variants effectively filter out UV radiation, preventing the photodegradation of chemicals like Silver Nitrate or Iodine solutions.
- Contamination Analysis: Supports the analysis of "Aseptic Handling"; using a dedicated dropping bottle prevents the "cross-contamination" that occurs when multiple students share a single large reagent bottle.
- Staining Evaluation: In microbiology and histology, these bottles allow students to evaluate the intensity of a stain (like Crystal Violet or Safranin) by controlling the duration and volume of application on a slide.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade, double-reinforced packaging. Bottles and pipettes/stoppers are often packed separately within the same carton to prevent mechanical collision and breakage during maritime transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and an MSDS for the glass composition.
- Durability: The ground-glass joints are precision-machined to ensure they do not "seize" or stick even when used with alkaline solutions, provided proper maintenance is followed.
Direct OEM Sourcing Advantages
Procuring StemAids Dropping Bottles directly ensures vertical manufacturing control:
- Uniform Drop Size: Direct oversight of the pipette tip diameter ensures a consistent drop volume (typically 20 drops/ml), which is critical for semi-quantitative laboratory work.
- Vacuum-Tight Seal: Our ground-glass stoppers are matched to the bottle neck using diamond-grinding tools, ensuring a perfect fit that prevents the evaporation of volatile solvents or the absorption of atmospheric CO?.
- Direct Factory Inventory: Guaranteed availability of bulk quantities for university-wide laboratory renovations or new facility setups.
- Quality Assurance: Every batch is inspected for thermal stress and glass thickness uniformity to ensure the bottles can withstand standard laboratory handling.
