The Rodent Tubular Holder is used to hold and/or restrain small rodents such as mice or rats during experiments or procedures. These devices are typically made of plastic and come in a variety of designs, such as a tube-like shape or a restraining box. They are used in research studies to hold the animal in a specific position or immobilize it during the experiment.
A single-channel pipette is a laboratory instrument used to transfer small volumes of liquid from one container to another. It consists of a thin tube with a calibrated volume and a plunger that is used to draw and dispense the liquid. Single-channel pipettes are commonly used in molecular biology, biochemistry, and other fields that require precise measurement and handling of small volumes of liquid.
