ION Propulsion is the preferred option for a wide range of space missions. Ion propulsion systems offer a more efficient use of fuel and electrical power as compared to other propulsion technologies. Therefore, ion thrusters are the preferred option for a wide range of space missions such as satellite station-keeping, orbit insertion, and deep space [...]

THE CHALLENGE: Validating the integrity of chemical injection lines The reliable operation of drilling, completion, and production equipment under extreme environmental conditions presents a major challenge as oil and gas wells continue to operate deeper within the earth. The single-use isolation device in chemical injection systems is a prime example of such a [...]

The challenge Molecular diagnostics are increasingly used for the rapid detection and identification of existing and emerging pathogens. The need for rapid results has required testing to move from normal settings, such as physician’s offices, to smaller, more widespread, and often temporary point of care (POC) locations. Sample cartridges can simplify polymerase chain reaction [...]

THE CHALLENGE Rapid and accurate amplification of nucleic acids (NA) for pathogen detection is critical in today’s global health environment. The most widely used amplification technique -PCR- also plays a vital role in genomics research, food and water quality monitoring, and species identification. Even if the target NA is present, adequate PCR amplification for [...]

THE CHALLENGE Clinical and research applications that utilize flow cytometers are demanding increased sample throughput. Additional demands are placed on the effective use of cytometers for single-cell analysis with smaller volume control. These multi-faceted demands on functionality require smooth, laminar flow for the sheath fluid and sample and low crossover volume to facilitate sample processing. [...]

THE CHALLENGE The maturity of next generation sequencing (NGS) instruments and constant demand for lower cost and higher throughput sequencing have led to new fluidic challenges that defy tradition. Instrument manufacturers are focused on adding fully automated library preparation and target enrichment to sequencers where precise control and repeatability are paramount. The objectives are [...]

THE CHALLENGE As companies involved in oil and gas exploration and production continue to push their boundaries into deeper wells, the reliable operation of drilling, completion, and production equipment under extreme environmental conditions is a major challenge. For example, chemical injection systems are dependent upon check valves that can prevent reverse flow of chemically aggressive [...]

THE CHALLENGE Protecting components from contamination is essential in critical fluid control applications, such as those found in the aerospace, power generation and automotive industries. While many systems are designed to be relatively immune to low levels of small size contaminants, single larger rogue particles can cause blockages which could result in system failure and [...]

THE CHALLENGE As companies involved in CubeSat space propulsion systems work to reduce system size and cost while simultaneously increasing performance, they require high value solenoid valves capable of exceptional performance in harsh environments. High performance miniature thrusters offer improved thrust to weight ratios which demand faster, more powerful and lighter valves. For example, miniature [...]

THE CHALLENGE The growing global market for environmental monitors is driving designers to produce portable devices which feature extensive battery life and are well-suited to their remote, end-use environments. These monitors typically employ solenoid valves to calibrate or auto-zero a sensor, pilot samples through a microfluidic chip, or exhaust system pressure. The current design challenge [...]

A leading automotive manufacturer struggled with the release of a new engine technology. They required an immediate solution to protect the launch date and their reputation. The Challenge More stringent regulations have led many original equipment manufacturers (OEMs) to implement gasoline direct injection (GDI) engines, which provide improved fuel economy, reduce emissions, and [...]

Download An Engineer's Guide to Selecting a Flow Restrictor A flow restrictor is any device that restricts or limits the flow of a fluid—generally a liquid or a gas. Such devices may also be referred to as flow limiters. Calibrated orifices are one example of flow restrictors. They are used in systems we encounter [...]

Download An Engineer's Guide to Selecting a Check Valve A check valve, also known as a non-return or one-way valve, is a mechanical device that allows a gas or liquid to flow freely in one direction while preventing reverse flow in the opposite direction. The direction in which the fluid or gas can flow [...]

Download An Engineer's Guide to Selecting a Pressure Relief Valve A Pressure Relief Valve is a mechanical device which allows a gas or liquid to escape from a section of a fluidic system when the pressure exceeds a predetermined limit. Pressure Relief Valves can serve several different functions within a system. The performance requirements [...]

Molecular diagnostics is revolutionizing the way we approach healthcare: The revolution of personalized medicine. Molecular diagnostics can detect health risks and diseases early to improve treatment, enhance disease management, and diminish subsequent health problems. The evolution of molecular diagnostics is escalating the demand for ever-increasing device automation to create faster sample throughput without compromising [...]

Ailments such as chronic obstructive pulmonary disease (COPD) and asthma require frequent monitoring and interventional therapies, such as monitoring exhaled nitric oxide in asthma patients or delivering portable oxygen therapy to patients with COPD. Even healthy athletes can benefit from cardio pulmonary diagnostic therapies that provide metabolic feedback of their performance, allowing them to develop [...]
