Beaker
Product Code : SCL-CLE-11933
The StemAids Laboratory Beaker is the most fundamental vessel in scientific research, engineered for mixing, stirring, heating, and temporary storage of liquids. Characterized by its cylindrical shape, flat bottom, and integrated pouring spout, it is designed for maximum stability and ease of use. Manufactured from premium Borosilicate Glass 3.3, these beakers are built to withstand extreme thermal gradients and aggressive chemical environments. Manufactured to ISO 3819 standards, they are essential for every level of laboratory activity, from basic education to advanced industrial R&D.

Key Pedagogical & Laboratory Outcomes
- Mixing Interface: Facilitates the understanding of Solution Homogeneity. The wide opening and flat base make beakers the ideal vessel for manual or magnetic stirring; learners identify how solutes dissolve into solvents to form uniform mixtures.
- Thermal Quantification: Enables the study of Enthalpy and Phase Changes; learners apply the beaker as a "water bath" or boiling vessel to record temperature changes during chemical reactions.
- Liquid Transfer Analysis: Supports the analysis of "Drip-Free Handling"; students evaluate the functionality of the integrated spout in preventing spills when transferring fluids to narrow-neck vessels.
- Volumetric Evaluation: Provides a platform for evaluating measurement precision; learners observe that while beakers have graduations, they are for "approximate" volume only, reinforcing the need for graduated cylinders or pipettes for high-precision work.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade, high-density packaging. Beakers are nested with protective interleaving and secured in reinforced, double-walled corrugated boxes to ensure "zero-breakage" during maritime or air transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and Material Safety Data Sheets (MSDS).
- Durability: Every beaker is annealed in a computer-controlled lehr to eliminate internal stresses, ensuring structural integrity even after hundreds of heating and cooling cycles.
Direct OEM Sourcing Advantages
Procuring StemAids Beakers directly ensures vertical manufacturing control:
- Uniform Wall Thickness: Direct oversight of the glass-blowing process ensures consistent thickness at the base and radius, which is the primary factor in preventing thermal stress fractures.
- Reinforced Rims: We ensure every beaker has a heavy-duty, fire-polished rim to resist chipping and mechanical impact during cleaning and storage.
- Direct Factory Inventory: Guaranteed availability of the full volumetric range, including specialized "Heavy Duty" variants for industrial applications.
- Quality Assurance: Every batch is "shock-tested" by transferring units from 100?C to cold water to verify compliance with international safety standards.
