Hettich EBA 21 Centrifuge Chosen for Research on Nanocrystalline Cellulose & Calcium Carbonate Nanoparticles Hybrids

Hettich EBA 21 Centrifuge Chosen for Research on Nanocrystalline Cellulose & Calcium Carbonate Nanoparticles Hybrids

The Hettich EBA 21 benchtop centrifuge was employed in the study “A transparent hybrid of nanocrystalline cellulose and amorphous calcium carbonate nano particles” by Denis Gebauer, VitaliyOlynyk, and their team of researchers.

The scientists sought to develop a bionano composite material because of its potentially impressive properties and environmentally benign and energy efficient production routes. The team attempted to combine nanocrystalline cellulose (NCC), the basic building unit of the most abundant biopolymer on Earth, cellulose, with amorphous calcium carbonate (ACC), the most abundant biomineral on Earth. Nanocrystalline cellulose (NCC) and amorphous calcium carbonate (ACC) were chemically processed to obtain nanocellulose hybrids.

The Hettich EBA 21 benchtop centrifuge was employed in several steps taken to obtain a nanocellulose hybrid. During the synthesizing process of ACC nanoparticles, ACC sediment was centrifuged at 6000 g. When preparing NCC, the centrifuge was run at 4500 rpm for 20 minutes to concentrate the cellulose and to remove excess aqueous liquid from the suspension. To prepare the coating, the scientists placed a silicon wafer with the dispersions in a conical tube and centrifuged it at 6000 g for 10 minutes using the Hettich EBA 21.

Ultimately, from the investigative study, the authors concluded that the resulting composition and thermal behavior of nanocellulose hybrids proved its potential for biodegradable multifunctional materials.

Hettich’s comprehensive line of centrifuges enables scientists to conduct important testing and research, such as this study on the potentials of nanocellulose hybrids. The Hettich EBA 21 is a versatile, quiet, safe, and reliable compact centrifuge that is suitable for clinical testing and research in many fields.
