graduated centrifuge tube
A graduated centrifuge tube is a precision-engineered laboratory vessel designed for separating substances of different densities through centrifugation. These tubes feature clear calibration marks along their length, allowing for accurate volume measurements from 1ml to 50ml. Made from high-grade, chemical-resistant materials such as polypropylene or polyethylene, these tubes can withstand high rotational speeds and maintain their structural integrity during centrifugation processes. The graduation marks are permanently molded or printed onto the tube surface, ensuring long-lasting visibility and accuracy. The tubes often incorporate a conical bottom design that facilitates the collection and removal of precipitates or pellets after centrifugation. They come with leak-proof screw caps or snap caps that prevent sample loss and contamination during processing. The transparent nature of the material allows for easy visual inspection of sample separation and measurement. These tubes are widely used in medical laboratories, research facilities, and industrial settings for applications including cell separation, protein isolation, and chemical analysis. Their versatility extends to storage applications, where the graduated markings prove invaluable for precise sample management and inventory control.
