PYREX Regular Weighing Bottle 40 x 50mm with Short External Joint

The PYREX 1686 Regular Weighing Bottle 40 × 50mm is precision laboratory glassware designed for weighing drying handling and temporary containment of laboratory samples. The 1686 series uses a distinctive short-length external ground-glass joint. Its glass closure fits over the externally ground upper portion of the bottle rather than inserting into the bottle opening. This provides a compact covered container suitable for analytical and gravimetric laboratory procedures. The 40mm diameter × 50mm height configuration provides a relatively broad sample chamber while maintaining a compact overall profile.
