Medical Devices

Precisely formulate and homogenize materials, with no entrained air for reliable device performance.

Joint replacements, lifesaving implantable devices such as pacemakers or central venous catheters, medical tools such as needles, syringes, and stents, all require bubble-free repeatable mixing.

FlackTek™ solves common challenges in the production of medical devices, making it easier than ever to rapidly develop, test, and produce new products using a wide range of materials such as resins, epoxies, adhesives, sealants, and coatings.

Are you struggling with any of these challenges?


The Challenge: Cross-contamination between different batches of materials can occur during the mixing process when using traditional mixing methods, leading to ineffective or spoiled batches. This can have serious consequences on product quality and safety.

The Solution: FlackTek™ technology eliminates the need to clean up after you’re done mixing, minimizing the risk of cross-contamination between batches. The optional use of single-use mixing containers in FlackTek™ equipment eliminates the potential for cross-contamination and ensures the production of effective and uncontaminated batches.


The Challenge: Incorporating fillers and additives, such as fumed silica and micro balloons, into mixtures poses challenges. These materials can be difficult to disperse uniformly, leading to inconsistent mechanical properties and potential moisture entrapment among other problems.

The Solution: FlackTek™ technology provides effective and uniform dispersion of fillers and additives, such as fumed silica and micro balloons, leading to improved product consistency and reduced moisture entrapment.The unique mixing action of FlackTek™ equipment enables efficient incorporation of fillers and additives into mixtures, eliminating agglomeration and ensuring homogeneous dispersion.

The Challenge: Polyurethane materials commonly used in medical devices exhibit high sensitivity to moisture. Introducing air bubbles during the mixing process can lead to moisture contamination during curing, compromising the integrity and performance of the final product.

The Solution: FlackTek™ technology ensures a non-invasive and bladeless mixing process, minimizing the introduction of air bubbles that can cause moisture contamination.The dual asymmetric centrifuge action of FlackTek™ equipment promotes naturally degases and provides efficient mixing, reducing the risk of moisture entrapment during curing. Added vacuum capabilities ensure no microscopic air entrapment will affect or contaminate the end product.

Still curious about processing with a FlackTek™?

What is the best method for effectively deairing silicones during the manufacturing process?

FlackTek™ mixers offer efficient deairing capabilities for silicones. The combination of dual asymmetric centrifuge action and vacuum degassing options available in the mixers ensures effective removal of air bubbles from silicone mixtures. This results in high-quality silicone components for medical devices, improving their mechanical and physical properties.

Are there any specific considerations or limitations when mixing different types of materials, such as polymers, metals, or bioactive substances?

FlackTek™ mixers are designed to accommodate a wide range of materials, including polymers, metals, and bioactive substances. The SpeedDispenser™ or SpeedDisk™ accessories offer efficient transfer capabilities, allowing for seamless mixing of diverse materials and facilitating the exploration of various material combinations.

What measures can I take to prevent cross-contamination between different batches of materials?

FlackTek™ mixers facilitate the use of single-use cups, eliminating the risk of cross-contamination between batches. The disposable cups provide a hygienic solution that ensures the integrity of each individual batch, minimizing the potential for cross-contamination. Custom materials are also available if the standard offering is incompatible with your mix materials.
