A Buying Guide for Lab Scales

A Buying Guide for Lab Scales
Used to determine the mass of an object, scales are among the most ubiquitous, important instruments in any laboratory or industrial setting.  And regardless of type, a professional caliber scale must be reliable, durable, and most of all, accurate. At NextDayScience, we offer ultra-precise, top rated platform scales, pallet truck scales, veterinary scales, and bench floor scales at competitive  prices. Here is more detailed information on our scale selection

Information about Thermocyclers and Hot Plate Stirrers

Information about Thermocyclers and Hot Plate Stirrers

Two common pieces of lab equipment are thermocyclers and hot plate stirrers. Here is some basic information about both to assist you in making your lab purchases.

Thermocyclers:

Thermocyclers, or thermal cyclers, are instruments used to amplify DNA and RNA samples by the polymerase chain reaction (PCR). The thermocycler raises and lowers the temperature of the samples in a holding block in discrete, pre-programmed steps, allowing for denaturation and reannealing of samples with various reagents. Amplified genetic material can be used in many downstream applications such as cloning, sequencing, expression analysis, and genotyping.


Definition, History and Applications of Electrophoresis

Definition, History and Applications of Electrophoresis
Electrophoresis, also known as cataphoresis and anaphoresis, is the motion of colloidal particles suspended in a fluid medium, due to the influence of an electric field. Breaking that definition down, in chemistry, a colloid is a mixture of insoluble particles that are suspended throughout another substance. For instance, milk is an emulsified colloid of liquid butterfat globules dispersed within a water-based solution. To qualify as a colloid, the mixture must be one that either does not settle or takes a very long time to settle. Add electricity to the equation, and you’ve got electrophoresis. Electrophoresis is a technique used in laboratories in order to separate macromolecules based on size.
