Secure and transport samples with confidence using the MVE 4/2V and 4/3V Series.
Enhanced performance and reliability with next-generation vapor shippers
MVE has redesigned its widely used 4L vapor shippers–the SC 4/2V and SC 4/3V–to provide improved performance and reliability. The SC Series dewars, recognized across the industry for their efficiency and durability, now incorporate patented BEND DON’T BREAK™ technology.
This advanced design features a newly contoured top head that flexes under high G-force conditions, enabling the dewar to absorb impact more effectively and substantially reducing the likelihood of structural damage during transport.
Additionally, MVE’s patent-pending Vapor Shield Technology helps protect against vacuum degradation resulting from LN2 overfill, further enhancing long-term performance.
These innovations reflect MVE’s continued focus on advancing cryogenic technology, supporting superior vacuum integrity, and reinforcing the SC Series as a trusted solution for long-term cryogenic storage.
