Microscale Leak Test

Microscale leak testing detects extremely small leak rates — often 5 to 100 microliters per minute — in sealed products like wearable electronics, battery enclosures, molecular assay cuvettes, and buffer packs. It requires specialized instrumentation capable of micron-level precision and thermal error elimination, such as InterTech's M1075 MicroScale Leak Detector.

SCCM (standard cubic centimeters per minute) is the standard unit for expressing microscale leak rates. InterTech's case studies show real-world limits as tight as 8 uL/min— for example, sealed wearable transmitters tested to a 0.03 sccm limit and buffer packs tested to 0.01 sccm — verified using proprietary transducer design and 28-bit A/D conversion for repeatable accuracy.

Acceptable leak rates vary by application and regulatory requirement, but InterTech's microscale systems commonly validate parts to limits between 5 and 100 microliter/minute — for instance, battery enclosures tested to user-selectable limits in that range, or molecular assay cuvettes tested to a 20 microliter/minute limit, each mapped to the product's real-world sealing performance requirement.

InterTech's MicroScale leak testing solutions are compatible with relevant ASTM standards, including ASTM F2338 and ASTM F3287, which are widely referenced for validating package and container closure integrity in medical and pharmaceutical applications.
