A multi-application leak and flow tester capable of performing leak tests up to 750psi

Our Sprint mD leak tester for medical device applications is designed to seamlessly integrate into your network. The SprintmD  leak tester communicates and assimilates process data to and from connected equipment, providing the intelligence required to optimize manufacturing quality processes. The SprintmD helps users achieve operational excellence by delivering improved process insights powered by embedded fieldbus technology combined with advanced security features to meet compliance requirements. With fast cycle times and capable of performing leak tests up to 750psi and the ability to accommodate a wide range of multi-functional and part integrity tests, the SprintmD is the ideal leak tester to meet the requirements for product testing within the medical device industry.

SprintmD was designed to accommodate a wide range of testing requirements

The SprintmD leak tester can be configured for up to five non-destructive leak and flow test combinations to support both part integrity and part performance leak testing.  The SprintmD leak tester also accommodates multifunctional testing, including pressure, vacuum, flow testing, occlusion, burst, and crack testing up to 750psi.

With the ability to perform both integrity and performance tests in a single instrument, the SprintmD:

  • Reduces training requirements
  • Eases technology adoption
  • Simplifies maintenance
  • Makes scaling operations less daunting
  • Maintains the highest levels of performance, while delivering fast cycle times and high repeatability.

Advanced security features enabling regulatory compliance and product performance requirements for medical device leak testing

With new security features, such as user authentication through passwords and roles, customizable access authorization, and the ability to log and monitor changes to parameters, the SprintmD leak tester enables compliance with standards such as 21 CFR Part 11 (U.S.), MHRA/EU Annex 11, and others.

Leak testing information at your fingertips to stay in control of your process

Through refined analytics that allow users to identify historical trends, the SprintmD leak tester identifies process degradation and helps to reduce transcription errors common with manual tracking. The SprintmD is capable of data collection, archiving, and reporting, making it easier to handle changes and retrieve data to support quality systems and manage processes.

The instrument also incorporates embedded fieldbus and expanded digital I/O, to optimize the control and selection of programs. With the SprintmD  leak tester it is possible to achieve two-way communication to send start and stop commands, select program commands, and communicate testing, accept, or reject status, as well as data from each individual step of the process.

The SprintmD leak tester is designed with simplicity and functionality in mind

With a large quick response touchscreen, the SprintmD leak tester makes viewing and accessing specific information easy. The interface is easier to navigate, for a more efficient user experience – including more information on the screen, more access to expanded information, and faster programming and screen reviews. The intuitive menu system provides access to a deep level of actionable data and reports and ensures quick programming.
