Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Precision Measurement & Mixing: Graduated markings enable accurate volume tracking, while the conical shape minimizes evaporation and aids controlled mixing for chemical reactions.
  • Secure Airtight Sealing: Ground glass stoppers with standardized joints ensure leak-proof containment for distillation, extraction, and pressure-sensitive experiments.
  • Thermal Stability: Borosilicate glass construction withstands extreme temperatures, supporting safe heating and cooling processes in laboratory settings.

Key features

  • 1. Borosilicate Glass Construction for Enhanced Durability

  • With borosilicate glass construction, you can safely handle extreme temperatures and corrosive chemicals, outperforming standard glassware in durability and resistance.* The material’s thermal and chemical stability ensures longevity in demanding laboratory environments.

  • 2. Ground Glass Joint Stopper for Airtight Seals

  • With a precision-engineered ground glass joint stopper, you can ensure airtight seals for precise reactions, reducing contamination risks compared to non-ground stoppers.* This design is critical for distillation, extraction, and other processes requiring controlled airtight conditions.

  • 3. Graduated Markings for Precise Measurements

  • With graduated markings in 50mL increments (e.g., 250mL, 500mL, 1L capacities), you can measure and transfer liquids with accuracy, minimizing experimental errors.* The clear visibility of contents further simplifies volume tracking.

  • 4. Conical Design for Stability and Efficiency

  • With a conical shape and wide base, you can stabilize reactions and reduce evaporation, ideal for both small-scale lab work and continuous processes.* The narrow neck minimizes surface area exposure, maintaining solution integrity during heating or mixing.

  • 5. Lab-Grade Material Compliance for Safety

  • With lab-grade borosilicate glass, you can meet industry safety standards for chemical and thermal resistance, ensuring reliability in professional settings.* The material’s compliance with laboratory protocols guarantees safe handling of aggressive reagents.
