What is a Calorimeter? Laboratory calorimeters measure the enthalpy, or heat transfer under constant pressure, produced or absorbed by a chemical reaction or a change in a material’s physical state. For non-combustible materials, calorimeters are used to determine the sample’s heat capacity. Once …
What is a Lab Disperser? How is it Different from a Homogenizer? Laboratory dispersers, sometimes referred to as high-speed shearers or rotor-stator mixers, are a type of overhead stirrer designed to disperse, rather than mix, compounds. As opposed to homogenizers, which uniformly mix two or more …
Uses for Balances in Laboratories Lab balances and scales are offered in a variety of designs to measure sample mass, density, and moisture content of solids, liquids, and powders. While a scale determines the mass of a sample, a balance is designed to compare the mass of multiple samples. Balances …
What is a Wet Bath and What is It Used For? Water baths, or wet baths, consist of a stainless steel basin filled with heated water and equipped with a digital controller. Water baths are used for sample thawing, reagent warming, substrate melting, coliform determinations, and bacteriological assays …
Laboratory Stirrers Comparison Chart Overhead stirrers consist of a stirring fixture, or stand, a digital controller, a drive shaft, and a motor for mixing viscous solutions. Overhead stirrers are used for a broad range of mixing applications including tissue grinding, cell media preparation, …
What is a Laboratory Hot Plate? Laboratory hot plates consist of a heating element installed underneath a plate surface, manufactured from conductive steel or plastic, connected to a digital or analog controller. What is a Laboratory Hot Plate Used For? Ubiquitous in clinical, production and …
What is Lyophilization? Lyophilization, or freeze drying, is a common technique used in the pharmaceutical and food industries to vacuum freeze samples for long-term, ambient storage. How Does a Lyophilizer Freeze Dryer Work? Freeze-drying equipment uses sublimation to remove water, or common …
What is a Pipette? Pipettes are the primary means for transferring liquids, often in milliliter and microliter volumes, into test tubes, microplates, and conical vials for analysis, storage or mixing. Pipettes aspirate a user-selected volume of liquid – samples, reagents, media – from one vessel, …
Liquid nitrogen vessels are designed to support long-term storage of samples at cryogenic temperatures (-196°C to -210°C). The process of cryo-preservation is widely used in clinical diagnostics, immunotherapy development, food and beverage, and semiconductor storage. Samples prepared with …
A – Lab Incubator Capacity (back to chart) Laboratory incubators are manufactured in a broad array of sizes, ranging from compact benchtop units smaller than 1 cubic foot to high-capacity, reach-in chambers larger than 40 cubic feet. Compact incubators (small-footprint, counter-top models under 6 …
