Heating and Cooling for Liquid Chromatography Systems

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.

Thermoelectric Cooler Assemblies for Reagent Storage

Introduction

Maintaining a temperature well below ambient, and monitoring this temperature carefully, are critical to extending the shelf life of reagents used for in vitro diagnostics. Most reagents require refrigeration and would spoil within hours at room temperatures. Reagents can degrade and become contaminated by microbial growth, which can affect test integrity results. Reagents can also be negatively impacted if they undergo too many freeze and thaw cycles.
