Frequently Asked Questions
Which tubes do these 17mm flange plug caps fit?
They are designed for 17mm-diameter tubes and standard 15mL centrifuge tubes, providing a press-fit seal at the tube opening.
Are these caps sterile?
No. These flange plug caps are supplied non-sterile in bulk packs of 1000 for general storage and organization use.
Why choose color-coded caps?
Five colors let you visually segregate samples by patient, study arm, timepoint, or assay step, cutting selection errors in high-throughput workflows.
Can these caps withstand organic solvents?
The polyethylene material handles aqueous buffers, dilute acids, dilute bases, and alcohols well, but offers limited or poor resistance to acetonitrile, aromatic, and chlorinated solvents.
