Portable gas flow meters are a simple solution to two key challenges associated with cleanroom metrology. The first is the strict cleaning and sterilization requirements to ensure no contaminants are introduced into the environment, and the second is a lack of electrical outlets to minimize crevices where bacteria can grow. Metrology is critical for cleanroom equipment ...

PVD coating techniques use physical processes to deposit thin films on surfaces. These films offer an extremely convenient way to obtain desirable surface characteristics without having to completely change the material of a product. The layers can be as thin as only thousandths of a nanometer and can transform all types of surfaces to resist corrosion, decrease friction...
The thin film deposition industry has rapidly evolved, bringing faster, more scalable, and highly efficient deposition setups. In this article, we explore two widely used deposition categories, chemical vapor deposition (CVD) and physical vapor deposition (PVD), and highlight their techniques and applications. What is thin film deposition? Thin film deposition involves...
Bringing drugs to market as quickly and cheaply as possible is imperative to treating the many diseases afflicting humankind. However, many of the diseases still untreated today are resistant to standard small‑molecule therapies, so pharmaceutical companies are turning to biologics and biosimilars to combat these difficult to treat diseases. Unfortunately, developing bi...
In the past, successes and failures of large‑scale biologics production could largely be attributed to the experience of the operators and their “magic touch” (or lack thereof). This is in stark contrast to Pharma 4.0, and its emphasis on connected, integrated data systems for best control of pharmaceutical manufacturing from benchtop bioreactor control systems to contro...
A supplier of valves for space launch vehicles validated each valve with bubble counts and pressure-decay tests, about five to ten minutes per valve. It integrated an Alicat laminar differential pressure mass flow meter into its leak test stand: each valve is leak-tested, then flipped and flowed forward at a set rate. Validation time fell by 90%, with an accuracy of ±0.5...
In metrology and inspection tools, a small drift in an optic purge, a carrier flow or a chamber pressure shifts the measurement baseline, and averaging does not remove it. A laminar DP mass flow controller turns a fixed restriction into a measured, self-reporting position: it reports mass flow, volumetric flow, absolute pressure and temperature from one body, warms up in...
Premixed cylinders are convenient but fixed. With Alicat mass flow controllers you can blend on site: one controller per gas, coordinated from one PC, holding the ratio in real time, for example a 60/40 argon and CO2 shielding gas. Gas Select switches between 98 to 130 preloaded gases without recalibration, and COMPOSER stores up to 20 blends of up to five gases at 0.1% ...
Before a gas panel or a mass flow controller ships to a deposition or etch tool, each channel is checked against a reference and the assembly is leak-tested. Integrators usually require at least 1% of reading across the flow range, and one reference cannot cover a span of about five decades. A ladder of laminar DP flow meters, each used only where it holds the 1% bar, co...
In reactive deposition, a chamber gauge reads only total pressure, so it cannot show that a low-flow reactive line has drifted, and the film composition shifts unseen. Controlling each line upstream fixes that: laminar DP mass flow controllers carry the argon or helium working line and the oxygen, nitrogen or hydrocarbon reactive line, with a repeatability of ±(0.1% of r...
A research spectrograph needed the air pressure inside its sealed 1,800-litre chamber stable to ±5 mbar, with a design goal of ±1 mbar, despite air leakage and long-term changes in ambient barometric pressure. Alicat modified one of its standard products: a dual-valve pressure controller that takes in dry air or vents to atmosphere when needed, with a deadband to reduce ...

Define which sludge boundary the process needs In a settling tank, “sludge level” may refer to the upper edge of a dense blanket, a transition zone or a suspended-solids cloud that the operator wants to keep away from an outlet. These are not always the same surface. Before choosing an ultrasonic transducer or an echo threshold, define the operational boundary and how it...
Background: Advancing Standardization and Reliability in CPET Applications The 2025 European Respiratory Society (ERS) Clinical Exercise Testing Guidelines highlight a growing shift in the role of cardiopulmonary exercise testing (CPET).[1] Beyond individual test results, modern CPET systems are increasingly expected to provide standardized, reliable, and comparable phys...
When shortness of breath appears only during activity, resting measurements may tell only part of the story. Exercise challenges the entire cardiopulmonary system, revealing limitations that may remain hidden under resting conditions. Cardiopulmonary exercise testing (CPET) turns exercise into a controlled physiological challenge, allowing clinicians to observe how the l...
Mobile cranes are used in situations where heavy loads must be moved flexibly and often under challenging conditions. The correct alignment of the machine plays a crucial role in this process. Even slight deviations from the intended position can affect the crane’s stability and, consequently, the permissible operating conditions. Reliable inclination measurement therefo...
Temperature is a critical process parameter in an aluminium extrusion press. Excessive temperatures can cause cracks, while insufficient billet temperatures increase resistance to deformation and accelerate die wear. During extrusion, friction generates additional heat, causing the temperature to rise along the profile. Reliable monitoring provides the information needed...

Memory Burn-in Test Systems play a role in semiconductor reliability testing, but HBM burn-in testing requires more than selecting a temperature range. High Bandwidth Memory (HBM) uses vertically stacked DRAM dies, creating different electrical and thermal requirements depending on the assembly being tested. For semiconductor manufacturers and reliability engineers, unde...
During battery testing in an environmental test chamber, the electrical program may change while the chamber-air setpoint stays fixed. When selecting a battery charge-discharge test chamber, the question is whether the load-test record covers the conditions your laboratory needs. Suppose a temperature trace starts after discharge begins, once the readings have already se...

After installing a flow meter, field engineers often face an important question: How accurate and reliable are its readings? A factory calibration report provides evidence of the instrument's measurement performance under specified calibration conditions. However, actual field conditions may differ from those in the laboratory. Factors such as tube material, tube dimens...
If a thermal camera and a thermocouple give different readings, the first question is not which tool is better. The first question is whether the two tools measure the same thing. A camera may be looking at the outside of a component while a thermocouple is attached to a different layer, mounted with a pad, or positioned at nearby point. The readings may also reflect di...
