Cleaning Pipettes in the Laboratory

Q. What are some best practices for lab cleaning of pipettes. We’re having trouble in our lab removing dried on residues.

A. The principal concern for any scientist or technician working in the laboratory is that glassware, like pipettes, be free of interfering residues after they are cleaned. Unseen residues can wreak havoc on analytical results by inhibiting culture growth causing cross contamination, non-reproducible results and more.
