Sandia researchers design unique microfluidic capillary fittings, manifolds and interconnects


The CapTite™ collection of capillary fittings are based on Sandia’s exclusive one-piece ferrule (patent pending).

The ChipTite™ series of manifolds and interconnects is fully compatible with CapTite™ and is easily adaptable to multiple chip configurations.

Pursuing commercialization of technologies spawned by its highly successful µChemLab(tm) project, Sandia National Laboratories is actively soliciting industry partners to license, manufacture, and sell a unique suite of microfluidic connection products.

Two distinct portfolios are being offered for licensing: The CapTite(tm) collection of capillary fittings, which is based on an exclusive one-piece ferrule; and the Chip-Tite(tm) series of manifolds and interconnects, which is fully compatible with CapTite(tm).

Microfluidic and lab-on-a-chip products are expected to provide superior benefits in many important and growing markets. The CapTite(tm) fittings and manifolds have the potential to find broad application in the existing research community as well as in many emerging markets, including proteomics, genomics, HPLC, micro-mechanical and micro-hydraulic assemblies.

In a market research study published earlier this year, Frost & Sullivan suggested that the microfluidics industry is also likely to benefit from the technological progress in complementary areas such as semiconductors and health care. Lab-on-a-chip devices are expected to eventually provide multiplexing and lower overall price for research, routine, and diagnostic testing. The overall market for microfluidics/lab-on-a-chip products, says the Frost & Sullivan study, is forecast to experience a rate of growth of 33.1 percent by 2008, or $710 million.

The CapTite(tm) collection is designed around a unique one-piece ferrule that eliminates sealing sleeves while providing unprecedented pressure capabilities up to 40,000 psi. These low-cost connectors are designed to be the smallest size easily finger tightened, and provide reliable, clean, reusable seals in a wide variety of materials. The complementary Chip-Tite(tm) series of manifolds and interconnects provides an elegant capillary-to-microchip interface. Jill Micheau, a business development associate at Sandia, said companies with the technical capability and manufacturing capacity to produce these devices for government and commercial applications are encouraged to contact Sandia for information on licensing. "These micro-scale machined junctions offer a modular solution to microfluidic designs and consistent fluid connections with simple and accurate registration," she said. The CapTite(tm) offering, added Micheau, represents an opportunity to license a product line with the potential to become the standard for use in microfluidic devices that will permeate the pharmaceutical, biotechnology, life science, defense, public health and food and agriculture markets.

Im Focus: Space observation with radar to secure Germany's space infrastructure

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to our data are in a better position to plan evasive maneuvers and prevent destructive collisions. From April, 25-29 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin.

The "traffic situation" in space is very tense: the Earth is currently being orbited not only by countless satellites but also by a large volume of space...

Im Focus: Researchers Discover New Anti-Cancer Protein

An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.

The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...

Im Focus: Researchers at Fraunhofer monitor re-entry of Chinese space station Tiangong-1

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.

Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...

Im Focus: Alliance „OLED Licht Forum“ – Key partner for OLED lighting solutions

Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP, provider of research and development services for OLED lighting solutions, announces the founding of the “OLED Licht Forum” and presents latest OLED design and lighting solutions during light+building, from March 18th – 23rd, 2018 in Frankfurt a.M./Germany, at booth no. F91 in Hall 4.0.

They are united in their passion for OLED (organic light emitting diodes) lighting with all of its unique facets and application possibilities. Thus experts in...
