Ensuring a single-use system dispenses at high speed and at the same
time is durable enough for commercial use requires rigorous testing. No
dosing system is appropriate for commercial use without proof of accu-
racy and precision over its operating lifetime. The maximum intended
run duration for commercial systems can last for up to a week or more
and involves 500,000 to 1,000,000 dosing cycles per station. This is well
beyond the design specification of many existing single-use dosing
systems.
A limitation to many current single-use presterilized dosing systems is the
plastic filling needle. The current plastic needles are not designed for com-
mercial filling operations. Most are too wide to penetrate small containers
