Thermoelectric Cooler Assemblies for Reagent Storage

Introduction

Maintaining a precise temperature below ambient, and monitoring this temperature carefully, are critical to extending the shelf life of reagents used in chemical and biological processes. Most reagents require precise temperature control and would deteriorate within hours due to poor refrigeration. When they are kept at room temperature, reagents can degrade and may become contaminated by microbial growth, which can affect test integrity results. Reagents can also be negatively affected by low temperatures if they undergo too many freeze-thaw cycles.

Thermoelectric Coolers for Handheld Cosmetic Lasers

Introduction

Handheld lasers have become a standard device in cosmetic surgery and medical spa applications. Handheld cosmetic lasers offer a wide range cosmetic benefits with minimal damage to the body and reduced patient recovery time. Even though thousands of microscopic laser beams make pinpoint contact with the skin, the process does not affect the surrounding tissue. However, lasers generate a significant amount of heat that must be quickly and efficiently dissipated to protect the patient, and the laser electronics.

Thermoelectric Coolers for Reagent Storage

Introduction

Analytical chemists use reagents to detect the presence or absence of a substance, or to test if a specific reaction occurs. Laboratory and medical technicians use reagents to cause a chemical or biological reaction to measure or identify a target substance. Biotechnologists consider antibodies, model organisms, oligomers, and specific cell lines as reagents to identify and manipulate cell matter. These reagents, especially those used by the biotechnologist, have narrow operating temperature windows which require refrigeration or freezing.

Cooling for Centrifuges

A centrifuge is a laboratory device using centrifugal force to separate liquid mixtures. To separate fluids, the centrifuge spins samples at a fast rate, resulting in heavy components to migrate away from the center axis and lighter components to migrate towards the axis. Centrifuge devices are widely used tools in food processing and medical research for cellular, genetic and protein analysis. When designing laboratory and medical centrifuges, several design challenges must be considered. 

Peltier Cooling for Refrigerated Centrifuges

 

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.
