Laboratory and medical-grade refrigerators are manufactured in a broad range of sizes, from benchtop models smaller than 6 cubic feet to upright, double-door models larger than 40 cubic feet. Refrigerators smaller than 6 cubic feet are designed to fit on crowded work surfaces or under pharmacy counters to provide point-of-use cold storage for media, reagents, or vaccines.
High-capacity, upright refrigerators include microprocessor controls to maintain precise, uniform conditions throughout the storage area to prevent sample spoilage due to temperature fluctuations. Double-door and triple-door refrigerators isolate samples from different production batches to prevent cross-contamination and exposure during refrigerator access.
Laboratory mixers consist of an oscillating, motorized platform, designed to hold flasks, beakers, or tubes, installed onto a stabilizing base and connected to an analog or digital controller to regulate the movement and speed of the platform.
Unlike high-speed lab shakers or vortexers, which mix samples in orbital or vortex motions, mixers gently agitate samples in linear rocking, tilting or rotating motions. Commonly used in molecular biology or biochemistry labs, mixers are ideal for gel staining, western blotting, or hybridization assays.
Laboratory mills, or laboratory mill grinders, utilize mechanical force to pulverize non-homogenous, batch samples into smaller, representative, homogenous samples for analytical and quality control testing. Mills are composed of a grinding element, such as a beater or cutting blade, housed within a stainless steel or disposable plastic milling chamber. The grinding element is connected to a high-speed motor regulated by a timer or digital controller.

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 the liquid or solid sample is combusted, the resulting temperature change, from the endothermic or exothermic reaction, is reported and used to determine the heat transfer resulting from the reaction.
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, wastewater purification, formulation of polymers, adhesives, and coatings.
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.
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 miscible components, dispersers create a mixture of two or more immiscible components owing to liquid-liquid or solid-liquid phase separations. Popular dispersions include emulsions (liquid particles dispersed into another liquid) or grind dispersions (solid particles dispersed into a liquid).
