Choosing a Culture Tube Size
Smaller diameters (12-16mm) are common for routine microbial culture work where sample volume is small, while the larger 25mm and 38mm diameters suit bigger sample volumes or applications needing more headspace. Round-bottom construction is chosen over flat-bottom where the tube will be mixed, vortexed, or incubated at an angle in a rack. Confirm the exact O.D. x length combination and quantity when requesting a quotation.
