Microfluidic Connectors for Lab on Chip Applications

By | Blog, News

The chip to world interface is one of the tougher problems to solve when developing a new microfluidic chip. While there are connectors available, the price can be daunting, pushing up development costs in areas where you’d rather not spend a lot of money. We’ve solved this issue using low cost injection molded, bondable connectors that are multi-functional and simple to bond using epoxy or UV cure adhesives. We routinely use these for custom Lab on Chip development programs, and now offer them for you to integrate into your own device. Bondable Hose Barbs in two styles: elbow or straight, for 1/16″OD or…

ALine and Fralock form Strategic Alliance

By | News | No Comments

Fralock (Division of Lockwood Industries, Inc.) and ALine, Inc. have entered into a strategic alliance to address all phases of microfluidic consumable development.  Clients in the Diagnostic and Life Science markets will benefit from access to ALine’s engineering and rapid prototyping capabilities, while having access to Fralock’s manufacturing process engineering expertise, and supply chain management. Offering the two company’s complimentary skills and manufacturing resources enables a wider variety of tools and processes to be considered early in product development, lowering risk at scale-up, while operating in an FDA registered and ISO13485 environment. Both Fralock, and ALine are based in southern…

Valves in Microfluidic Cartridges

By | Blog, News | No Comments

In a single-use cartridge for the point of care, why use pneumatic control of on-board diaphragm valves in the cartridge when a linear actuator against a flexible layer works just as well? This question was recently posed by a client as they consider their development path from proof of concept. They envision a couple of different product use environments, one involving a benchtop instrument, and another a portable handheld using battery power. In some cases, the answer might just boil down to personal preference. But from a development perspective,  pneumatically controlled on-board valves offer more flexibility in design of the cartridge….

It’s a Materials World

By | News, Newsletters | No Comments

What happens between a surface and a fluid stream can lead to foul play. That’s why I’m a materials girl. The complex physics and chemistry of surfaces is an important consideration in any product development, and is particularly important for microfluidic systems where the high surface area to volume ‘concentrates’ the effect of the surface. The choice of materials should be taken into consideration during the early design of microfluidic devices to enable applications including cell culture, immunoassays, or nucleic acid amplification. With sophisticated workflows for immuno-analysis, materials impact assay sensitivity, limit of detection, fluid circuit functional performance, and shelf-life….

A Systems Approach to Microfluidics Products

By | News, Newsletters | No Comments

One of the complexities of Microfluidics Product Development is the need to integrate the functional performance of a variety of dissimilar components. It involves a combination of science, engineering, and materials science to create a robust product solution. Ultimately, any product that performs tests and measurements is fundamentally an information producing system, and the quality of the information depends on how well each of it’s disparate components are harmonized to become ‘more than the sum of the parts’.

Experts In the Science and Engineering of Microfluidics

By | Blog, News, Newsletters | No Comments

ALine’s expertise in microfluidics design and production, integrates custom fluid handling in a single-use device with semi-automated instrument control. Our toolbox of well characterized on-board valves, pumps, metering, mixing, and de-bubbling strategies perform robustly with manufacture scale up. Starting with an assay that is performed in a microtiter plate, ALine translates the manual workflow into a semi-automated process in a microfluidic device. In as little as 60 days, you can be running your target assay in a customized microfluidic device with automated control in an instrument, and begin optimizing the device design and reagents to achieve proof of principle..
