TUBES
Round bottom
：
Have a uniform wall thickness and provides a better fit in a rotor
than conical bottom tubes. Round tubes withstand higher
g-forces.
Conical bottom
：
Ideal for cell culturing and ammonium sulfate precipitations.
1. All centrifuges have come with the tube holders, in which a rubber
cushion is installed inside the tubes.
2. The tube adaptor is applied to the volume either 10ml or 15ml.
3. Do not place the cushion upside down or in a slant position.
4. Replace the cushion once the glass tube is broken.
5. Be sure the tube adaptors are placed into the rotor completely.
