life science companies. Dexter has developed customised solutions that meet the most stringent requirements. The company is focused on the success of its customers, whose products improve quality of life. Dexter develops
custom magnetic solutions utilising permanent magnets, electromagnets and magnetic assemblies. Located in Elk Grove Village, Illinois, Torrance, California, and Freiburg, Germany, Dexter can provide support throughout the US and Europe. Dexter’s technology team engages its customers early in the design process. The company focuses on the customer’s requirements and adhere to a ‘stage-gate’ process to deliver manufacturable products that are controlled, reliable and repeatable. Backed by a robust quality system, state-of-the-art measurement and metrology equipment and supported by market specific quality engineers ensures Dexter’s solutions meet its customer’s standards. Magnetic medical devices require expert consideration of the selection of materials, biocompatible solutions, stray field management, controlled manufacturing processes, as well as high-quality and precision machining. To ensure the highest standards that exceed customer expectations, Dexter is ISO 13485 certified and has a class 10,000 cleanroom. As an expert in implantable solutions, Dexter understands the critical nature of biocompatible coatings.

Dexter has developed its own process for coating NdFeB magnets with BarrierMax Parylene C, which provides superior performance. In medical applications, Parylene C is a transparent, pinhole-free, thin, conformal coating that provides ideal corrosion resistance and barrier properties. Dexter began developing the BarrierMax coating process in 2018 and tailored its formulation to optimise performance on NdFeB magnets.

Custom-etched metal components
others are standardised for large production runs year after year, such as: ■ RF shields ■ Titanium implant parts ■ Stainless steel surgical snares ■ Gold-plated copper for ablation
Fotofab is the solution for thin metal- part needs.
Fotofab has delivered the highest-quality custom-etched metal components to the medical industry for more than 50 years. Its manufacturing technique of photochemically etching sheet metal uses acids to fabricate more precise components. With other techniques, like laser etching or metal- stamping, the fine lines needed in a microscreen or the delicate intricacies of implantable parts cannot be made to the tight tolerances and sheet thinness that Fotofab can provide. The company’s process of chemical metal-etching offers centre-to- centre tolerances within 0.0005ins, maintaining the metal’s full integrity. Fotofab’s portfolio includes a diverse product line of elaborately detailed pieces with complex geometries or simple parts like washers and shielding components. Some are quick-turn prototypes and
The company’s process begins when a component drawing is submitted for a quote. Its dedicated team of technical engineers review the request to guarantee metal type, capability and timing needed. Once dimensions are agreed upon and approved, the metal can be etched in a matter of hours. This results in consistent parts, on time and within budget. Along with photochemical etching, Fotofab offers an array of finishing services for the fabricated parts, including: ■ Thin metal forming ■ Electropolishing ■ Passivation ■ Plating (standard and precious metals)
As a full-service provider, Fotofab works with more than 35 types of metal alloys, including titanium, stainless steel 300s and 400s, and Elgiloy. It is ISO 9001:2015-certified and RoHs compliant, committed to the quality of its products and the satisfaction of its customers.

Cost-effective glass components Glass remains the material of choice for many biophotonic and microfluidic applications. It is inert to most chemicals, has unsurpassed well-defined optical properties, and has good temperature and pressure stability. However, glass components also have a reputation for being prohibitively expensive to manufacture, which means that using them
IMT produces customised high- precision, low-cost glass components.
as a consumable or semi- consumable in high-quantity applications is not cost-effective. In several cases, it appears to be the cost of the consumable glass components that prevents a new analytic method or technology from entering the mainstream. Realising the market potential of high-precision but low- cost glass components, IMT of Switzerland is applying the foundry concept to the production of glass components for life sciences, such as microchannels, through-holes, electrodes and waveguides. By combining the development and production of glass components for many companies at one site and applying manufacturing technologies from the semiconductor industry – and thereby reaching attractive economies of scale – IMT can offer customised glass components at competitive prices. IMT has more than 50 years’ experience as a supplier of custom-made glass components for a wide range of optical and sensor applications including delineated optics, reticles, gratings, mirrors and filters. The company’s core expertise is the coating and structuring of thin films using microlithography. Its production environment – which includes 1,300m² of cleanrooms and a fully automated process line for 200mm glass wafers – is well suited to the mass production of lab-on-a- chip glass components, flow cells containing microchannels, and metallic and dielectric microstructures, in combination with waveguides and gratings.
