Borosilicate Erlenmeyer Flask Sets

Features:

• Comprehensive Sizing: These kits cover the full spectrum of laboratory needs, from micro-scale reactions (50 mL) to large-volume preparation (1000 mL).
• Even Heating: The precision-molded uniform wall thickness ensures consistent heat distribution, reducing the risk of stress fractures during heating cycles.
• Easy Identification: Each flask features a large matte marking spot and sharp enamel graduations for quick volume estimation and sample labeling.
• Classroom Ready: Specifically packaged for safe transport and storage, these sets are ideal for high school and university chemistry departments.

Laboratory Care & Safety Tips:

• IMPORTANT! Thermal Management: While borosilicate glass is heat-resistant, avoid placing a cold flask directly onto a pre-heated high-temperature hot plate. Gradual heating is always recommended to maximize the lifespan of the glassware.
• Stoppers: For a secure seal, a #1 or #2 stopper typically fits the 50 mL flask, while a #8 or #9 stopper is required for the 1000 mL size.
• Cleaning: These flasks are fully autoclavable and dishwasher safe. Use a narrow-neck flask brush to reach the bottom corners for thorough cleaning.
