New and disruptive life-saving opportunities are rapidly occurring in the diagnostics space. These products need to launch and scale at an accelerated rate. For over two decades, Natech has brought ideas to life as the contract development and manufacturing organization for the IVD industry. Filling and sealing has become integral for many diagnostics devices.
Our expertise in manufacturing for lateral flow, molecular diagnostics, and microfluidics will help move your ideas from concept to commercialization. Together, let’s bring your life-saving ideas to life and make sure great products get made.
Filling and Sealing
After injection molding, many IVD products require filling and sealing with various liquids and reagents.
Natech’s team of engineers develop customized solutions for low and high volume production. This includes custom stations, automated processes, custom packaging and final assembly.

Product Highlight: Extraction Tube
Natech’s IVD clients have struggled to find a reliable supplier for extraction tubes. To overcome this challenge, Natech’s engineering and manufacturing teams developed a custom extraction tube.
Additionally, Natech manufactures, fills, seals, and packages this metered-dose extraction tube. You can customize this product to fit your diagnostics testing needs. Natech invested in new technology and equipment to support the development of this extraction tube.
Natech’s custom extraction tubes are used alongside many different rapid diagnostics tests, including COVID-19 tests.

Leak and Seal Testing
For devices that are meant to be filled and sealed, there is a risk that the liquid could leak. Depending on the type of seals in an application, the seals can be tested via weight loss evaporation testing, pull force testing, and or vacuum testing.
Example 1: Torque Testing Using a Torque Wrench
Torque is a twisting force that causes rotation. You can apply torque to a nut, bolt, screw etc. A torque wrench is a tool that can quantify the amount of torque, or twisting motion, applied. To test one of our custom products, our engineers applied torque via a torque wrench to simulate someone tightening the cap onto the container body.
Natech uses torque testing to apply torques of various measurements to quantify the most suitable torque that creates the best seal. The best seal would be measured by the least amount of liquid evaporated from the tube over time.
Example 2: Accelerated Shelf Life Test Using a Heat Chamber
Natech uses a heat chamber that heats up using forced air convection and a fan that cycles the air inside.
An “accelerated shelf life” test simulates a shelf life for a product that would take years in regular conditions, but when heated up for a shorter amount time, simulates that shelf life expectancy.
Exciting developments in the life sciences and IVD markets mean more opportunity for industry startups, innovators and disruptors. Our mission at Natech is to make sure great products get made, and we have developed solutions to help innovators launch and scale their game-changing products.
