Chips & Tips
Welcome to Chips & Tips - a unique and regularly updated forum for scientists in the miniaturisation field. Chips & Tips aims to provide a place where ideas and solutions can be exchanged on common practical problems encountered in the lab, which are seldom reported in the literature.
Do you
. have problems with bubble formation when injecting your sample?
. wish there was a quicker way to make prototypes?
. find connecting chips to pumps and syringes problematic?
Or
. do you have your own tricks to overcome these or similar problems?
If so, then Chips & Tips is the forum to address your requirements.
Read the tips below or see the author guidelines on how to submit your own today!
