ISO/IEC 17025 Accredited Laboratory


and testing


Our ISO 17025 accredited laboratory upholds the highest requirements and principles under this exacting quality system and is symbolic of our commitment to precision calibration.

medical packaging begins with accredited calibrations

Our ISO-17025 accredited laboratory is ready to serve our medical device packaging customers. Let us help you get a solid start on your medical device packaging program. Our laboratory can provide a comprehensive machine calibration, a vital foundation for your installation qualification. Our advanced laboratory has even created our own patented technologies for evaluating medical device pouches. Keep your medical device packaging program compliant with calibration and laboratory services from Van der Stahl Scientific. Let our competent staff of trained technicians perform a comprehensive calibration or let us evaluate the seal strength of your medical device pouch.

Machine Calibration

Our sealers ship to you from our fully accredited ISO-17025 calibration laboratory. We perform temperature calibrations at multiple internal thermal zones for better accuracy. We also verify that the force is within spec or we perform a multi-zone force calibration on the force transducer.

Pouch Testing

Our laboratory not only performs medical device pouch testing, we have invented and patented systems that we sell to our customers. We can provide pouch seal strength studies to help you develop nominal settings for your packaging machinery.

Service and Repair

Our highly trained technicians can provide a complete service or repair on your packaging machinery. Every technician at Van der Stähl Scientific is certified in a quality system and understands the critical nature of a medical device packaging machines

Force Calibration

The amount of force that is being applied to your pouch needs to be understood to develop a cogent medical device packaging validation. With our precision transducers and advanced meters, we can verify critical machine force, and will provide easy to read reporting.

ISO 17025 Accredited

If you are a ISO 13485 medical device organization then your quality team is held to the highest standard in manufacturing. Partnering with vendors that are also ISO accredited is vital to your total quality plan. Why not begin your medical device packaging validation with a company that understands quality systems?

Medical device packaging support laboratory

Our ISO 17025 laboratory means we test, inspect and calibrate to ensure the highest quality standards for the machines we sell. When your customer list includes NASA and the Centers for Disease Control, absolute quality is paramount. We have developed and patented systems to help medical device manufacturers reach their goal of precision in medical device sterile packaging. Our ISO 17025 accredited laboratory upholds the highest requirements and principles under this rigorous quality system. Our accreditation is symbolic of our commitment to total quality.

  • Thermal mapping and calibration
  • Platen force calibration
  • Tension calibration
  • Comprehensive inspection reports
  • Annual preventive maintenance
  • Machine repair services
  • ASTM F-88 seal strength testing
  • thermocouple dry well calibrations

Range Calibration

The best medical device packaging validations are built on a machine calibration that explores the usable range of thermal performance. With our range calibration we will verify packaging machine compliance at 3 temperatures for a more complete calibration.

Time Verification

When developing your DOE (design of experiments) it is vital that you understand the value of all measured attributes. With our laboratory developed system, we can verify our machinery’s adherence to time set points. Understand all critical points for a stronger I.Q.

Additional services and support from our laboratory

Pouch Testing

The ASTM F-88 tensile test is still the workhorse standard for understanding medical device pouch seal strength. We will perform a 30 specimen study on your pouches expressing the data to a plot graph as well as a histogram for interpretation. This is the most important study we perform in our lab.

Validation Support

Our founder comes from a surgical device background and understands the challenges facing medical device makers. Call and speak with our on-staff CPP and take advantage of all we have learned from over 20 years of sterile device packaging. Certified support from a team of professionals.

Supporting Documents

A medical device validation is only as good as the verified documents that chronicle each step of the process. Our comprehensive support documents help you develop a needed audit trail for a packaging validation. Easy to understand and interpret, our documentation is just the support you need.

Calibration Training

The final step in maintenance is machine calibration. Our calibration training will demonstrate how to select the proper meters and tools for your unique sealing machine. You will learn from our highly trained senior technicians as they guide you through each step in the calibration process.

Service Training

If you have one of our pouch sealers, then this course is for you. We cover the full spectrum of maintenance issues from inspection to parts replacement and machine adjustments. With this course, you will also have full access to our online Calibration and Technician Certification course.

Dye Penetration

Under our ISO/IEC-17025 scope of accreditation we can now perform dye penetration studies using the ASTM 1929 standard. We will provide you with 2 Dye Penetration reports that include a technician’s summary as well as photographs of the study for your records and a better packaging validation.

Packaging machine service and accredited calibrations to go

Now you can receive the same high level service and calibration we offer in our laboratory, right in your cleanroom. We can travel throughout the US and we typically offer single day service in Southern California. For our customers that want their services delivered onsite we are here to accommodate.
