Introduction

Centrifugation is a process that separates mixtures through centrifugal force. Centrifuges are commonly used in food processing and medical research for protein, genetic and cellular analysis. In medical laboratory settings, centrifugation involves spinning medical samples at a fast rate to filter or concentrate substances based on differing densities. Dense components migrate away from the center axis, while less dense components migrate towards the axis.

Introduction

Point of care testing (POCT) aims to bring medical care conveniently and immediately to the patient. The sophistication of medical and laboratory testing devices now enables accurate, real-time diagnostic test results within an hour, rather than days. POCT is addressing the importance for doctors and patients to rapidly receive test results to not only improve patient care, but also improve public health. The recent global COVID-19 pandemic has shown that rapid testing is vital to effectively manage the spread of a virus.

 Introduction

High-performance liquid chromatography (HPLC) is a technique used for analysis of liquid mixtures by separating, identifying, and quantifying their constituent components. Liquid chromatography normally operates with smaller amounts of material and seeks to measure the relative proportions of analytes in a mixture. R&D laboratories in the pharmaceutical, food science and oil industries use these instruments for product development or reverse engineering.

Introduction

Incubators, used for cell and tissue cultivation in hospital and laboratory settings, grow and maintain cell and tissue samples under controlled conditions for hours, weeks, or even months. They create the ideal environment for cell and tissue sample growth by maintaining optimum levels for temperature, humidity, carbon dioxide, and oxygen. Precision control of these factors enables research and experimental work in industries where cell culture is vital, such as zoology, microbiology, pharmaceutical research, food science, and cosmetics. 

Introduction

At Laird Thermal Systems, we are committed to eco-friendly solutions for temperature stabilization for demanding applications across global medical, analytical, industrial, transportation, and telecommunications markets.

Older compressor-based systems often use high global-warming potential (GWP) HFC refrigerants like R134a and R404A. New industry requirements are moving away from the use of such refrigerants due to their environmental impact. New government restrictions on traditional and natural refrigerants are central to compressor-based systems.

Introduction

Miniature optical packages provide a robust hermetic seal to protect small image-sensing components, including CMOS, CCD, IR, and X-ray detectors. Optical packages, like Transistor Outline (TO) Cans, are widely used for image-sensing applications. For high-end image sensing, micro thermoelectric coolers (TECs) can be integrated into optical packages called Optical Thermoelectric Assemblies (TEAs). This will provide deep cooling to temperatures well below ambient to minimize thermal noise and capture maximum light spectrum.

Introduction

Fiber optic technology has essentially replaced copper wire in datacom and telecommunication industries. Emerging applications, including artificial intelligence and machine learning, require higher data transfer speeds and bandwidth across significant distances all at a lower cost.
