Is the epTIPS Box or are the epTIPS Racks UV-resistant?
The UV stability of the existing epTIPS Box of polycarbonate and of the existing epTIPS Racks of polypropylene were tested during development. These were thereby irradiated with a lamp of 254 nm and energy of approx. 1 J/cm2 for 16.7 hours. After 10 cycles, thus a total of 167 hours, there were still no signs of adverse effects on the box material. Because the energy of the lamp used is considerably higher than that of a lamp used in a sterile bench, it can be assumed that both boxes can be exposed to UV radiation for at least 300-600 hours in a sterile bench without problems. Because it is well known that polypropylene is at least 3 times more stable against UV radiation than polycarbonate, correspondingly longer UV stability under sterile bench conditions can be presumed for the epTIPS Racks.
