For laboratories dealing with smaller volumes of samples (volumes in microliters), the ideal decision is really a micropipette.
Drug shipping: used in pharmaceutical exploration and scientific configurations for exact drug shipping, pipettes prepare and administer managed amounts of remedies, making certain correct dosing and client security.
