Can anyone suggest the specification of the test tube used for the tube adherence method for biofilm assay?

when we grow biofilm in test tube, the pipette often do not reach near the content. so we have to decane it directly or use a smaller test tube.

Dear Vijay,

Do you have information on how thick a biofilm can be on vegetables and how the biofilm is distributed? Optical coherence tomography (OCT) is a tool that enables non-destructive in-situ imaging of biofilms. Assume it will be suitable for vegetable when the biofilm is thick enough. Examples of OCT data on biofilm formation on membranes for drinking water production can be found here.
