Moran, Paloma; Galindo, Juan – Biochemistry and Molecular Biology Education, 2011
We report a practical home-made microcentrifuge to be used for teaching purposes. It was made using a salad spinner and two polymerase chain reaction (PCR) tubes racks. It can accommodate 2 standard size 96-well plates or 24 strips or up to 192 microfuge tube. The centrifuge is hand-operated and is ideal for short spin down purposes. (Contains 3…
