Frequently asked questions
Polypropylene or polystyrene?
Choose polypropylene (this tube) for speed and chemical resistance: Globe rates it to 3,000 × g, against 1,500 × g for the polystyrene 6260. Choose polystyrene when you need to read the contents by eye.
Where do the graduations run?
From 0.5 mL to 15 mL in 0.5 mL steps. They are molded into the tube wall, not printed, so solvents and handling do not wear them away.
What size racks and adapters does it need?
It is 17.5 mm across and 120 mm long with a conical bottom, the size that racks and rotor adapters list as 15 mL conical.
