Description
Caps for Schlenk flasks provide a secure, airtight seal for air-sensitive reactions, inert-gas handling, and vacuum line operations. Made from BORO 3.3 glass compliant with ISO 3585 and aligned with ASTM E438 Type I specifications, these caps offer exceptional resistance to thermal shock, aggressive solvents, and repeated heating cycles. The precision-ground interface ensures reliable sealing during Schlenk techniques, reducing oxygen and moisture exposure and supporting controlled manipulation under nitrogen or argon. LabChoice Australia supplies these caps with highly accurate tolerances to maintain stability across routine synthesis and advanced organometallic or moisture-sensitive workflows.
The robust BORO 3.3 construction maintains dimensional accuracy under temperature variation, allowing safe use with Schlenk flasks during evacuation, inert-gas purging, and reflux operations. Their chemically resistant surface prevents degradation when exposed to halogenated solvents, strong bases, and common reagents used in synthetic chemistry. Suitable for university research labs, industrial R and D, and advanced teaching laboratories, these caps integrate seamlessly into standard Schlenk lines and vacuum manifolds. LabChoice Australia maintains local stock for reliable availability, ensuring researchers can work with confidence, precision, and compliance with internationally recognised glass standards.
