Sample Preparation

Biological applications such as bioimaging, cancer treatment, tissue engineering and optical coding are just a few ways nanomaterials are being used in the lab today. Unfortunately, factors of nanoparticles, such as internal collisions with molecules, thermal motion, and gravitational forces affect the physical stability of nanoparticles making them difficult to work with in clinical applications or materials science.

Today’s centrifuges are more sophisticated than ever. Consequently, customers can find platforms that fit right into today’s wide range of centrifuge applications. In fact, Nick Horsley, general manager at Hettich Instruments in Beverly, Massachusetts, says, “Centrifuge accessories have become very important.” Those accessories can help a lab select a system that can multitask.

Learning to use evaporation starts very early in chemistry. For students, the process takes a very simple
approach, maybe just putting a solution in a beaker over a flame and waiting. That technique, though,
doesn’t provide the sophistication, control, or throughput that advanced techniques require. Consequently, scientists can use dedicated evaporators.

Turning a sample into a suspension—the essence of homogenizing—occurs in a wide range of laboratory applications. In life science and clinical research, scientists often homogenize tissue samples for various analytical studies.

Centrifuges work on the principle of sedimentation facilitated by an apparent angular force that draws components of a rotating sample away from the center of rotation. Although centrifugation theory is straightforward, its engineering literature is voluminous due to the number of industries and research operations that depend on the operation.
