What are Heterogeneous Samples? A mixture is defined as a combination of two or more substances, which may or may not be chemically combined. A mixture can be either heterogeneous or homogeneous depending on the extent to which the substances are combined, as well as the uniformity of composition. A homogeneous mixture has a uniform […]
Introduction Micropipettes are an indispensable part of any scientific research laboratory. Today, they are used in almost every scientific / research experiment. The instrument has made the life of scientific community all over the world very convenient. But have you ever wondered about a micropipette’s history? How was it invented and how did scientists handle […]
As modern researchers increasingly work with high-value small volume samples, the need for advanced pipetting techniques/protocols is evident. In order to detect microscopic changes accurately in small sample volumes, test tubes and vials are being gradually replaced by microplates, which require reagents in the microliter/nanoliter range. While working with small volumes, factors such as temperature […]
You might have taken control of all the possible variables involved in your cell culture experiment, and feel assured that your study is free of any type of contamination causing agent. However, contamination caused by a pipette and its tips lurk discreetly in the corner, and are likely to be overlooked by many researchers. When […]
Mechanical displacement pipettes have been in use across a gamut of laboratory / scientific research applications for more than 50 years. These pipettes are user-friendly, and can be used to dispense a variety of liquid formulations. The working principle of a displacement pipette is straight-forward. The push button on the pipette is pressed, and the […]
