Care Guide
This authentic Supertek 250ml Erlenmeyer flask is crafted from heavy-duty, heat-resistant borosilicate glass 3.3. The used laboratory flask is in excellent condition with no chips, cracks, or flaws. It features a narrow neck design that fits a tight-sealing black rubber stopper, which is included. The clear glass body has crisp, easy-to-read white graduation markings for volume measurement. It measures 6 1/4 inches tall. This narrow-mouth flask is ideal for scientific laboratory chemistry experiments, school science classrooms, liquid mixing, or professional research environments. It can also function as a unique decorative piece or propagation vase for home and office spaces. See my listings for more labware items.
Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.
Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.
Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.
Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
