Reagent Bottle with Screw Cap
Product Code : SCL-CLE-11924
The StemAids Reagent Bottle with Screw Cap (also known as a Media Bottle or GL45 Bottle) is the laboratory standard for the safe storage, mixing, and transport of chemical reagents, culture media, and solvents. Engineered from high-purity Borosilicate Glass 3.3, it features a standardized GL45 thread and a leak-proof screw cap with a pouring ring. Manufactured to ISO 4796-1 standards, it provides superior resistance to thermal shock and chemical attack compared to soda-lime glass or plastic alternatives.

Key Pedagogical & Laboratory Outcomes
- Containment Interface: Facilitates the understanding of Chemical Stability. Learners identify how the airtight seal prevents the evaporation of volatile solvents and protects hygroscopic reagents from atmospheric moisture.
- Volume Quantification: Enables the storage of large-batch solutions; learners apply the permanent graduations to monitor reagent levels during long-term experimental series.
- Safety Analysis: Supports the analysis of "Drip-Free Transfer"; students evaluate how the integrated pouring ring prevents corrosive chemicals from running down the side of the bottle, protecting the user and the laboratory bench.
- Sterilization Evaluation: In biology, these serve as the primary vessel for evaluating sterile technique; the Borosilicate 3.3 construction allows for repeated autoclaving of nutrient agar or broths without glass degradation.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade, high-density packaging. Bottles are packed with caps attached but not fully tightened to prevent pressure-locking; they are nested in heavy-duty partitions to ensure zero-breakage during maritime transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and Material Safety Data Sheet (MSDS).
- Durability: The thick-wall construction is designed to handle mechanical impacts better than standard Erlenmeyer flasks, making them suitable for long-term inventory storage.
Direct OEM Sourcing Advantages
Procuring StemAids Reagent Bottles directly ensures vertical manufacturing control:
- Standardized GL45 Threading: Direct oversight ensures that the threads are mathematically precise, allowing for total compatibility with standard dispensers, stirrers, and replacement caps.
- Chemical-Resistant Graduations: We utilize high-contrast white enamel that is fired onto the glass, ensuring the scale remains legible even after exposure to strong acids or repeated cycles in a laboratory dishwasher.
- Direct Factory Inventory: Guaranteed availability of Amber Glass variants for light-sensitive reagents (like Silver Nitrate) and Clear Glass for general use.
- Quality Assurance: Every batch is "pressure-leak tested" to ensure the cap-to-glass interface provides a hermetic seal.
