PYREX® Low Actinic Flat Bottom Boiling Flasks, Corning 54100
PYREX® low actinic flat bottom boiling flasks have a full length outer standard taper joint, but with a shorter neck. Low Actinic stained glass provides protection for materials sensitive to light. The protective color is an integral part of the flask, which retains the mechanical strength, chemical stability, and thermal resistance of PYREX® labware. Manufactured from borosilicate glass Code 7740.
