Qorpak Bottle Beakers® also known as Graduated Medium Rounds are excellent for use with biological and pathological specimens, but can also be used for storing industrial laboratory chemicals and reagents. These clear / flint bottles are designed with a slight shoulder for easy pouring and handling. Graduated in ml and ounces. Mix, measure, and store in the same container.
Attached green thermoset (phenolic) are known for providing the widest range of chemical compatibility and for being the most temperature tolerant of plastic closures. The color green easily identifies the PTFE liner system. Foam backed PTFE liners resist attack from virtually all chemicals at room temperature and provides resilience for a tight seal with a low moisture transmission rate. F217 has a low density foam core between two solid layers of LDPE. Uses include analytical lab samples, high purity chemicals, strong acids solvents, environmental samples, pharmaceuticals, and diagnostic reagents.
