Case 1. International transportation from Europe to Japan (2 ℃ ～8 ℃ range)
・ Purpose: Actual transportation test assuming imported investigational drugs from Switzerland to Japan
・ Period: 15th December, 2020 to 4th January, 2021
・ Transportation route: Switzerland (Zurich) → Qatar (Doha) → Japan (Kansai International Airport) → Shiga (Panasonic)
・ Transportation temperature range 2 ° C to 8 ° C
・ Equipment used: VIXELL Type-S (AE-V06GXR) + Thermal storage unit (AE-V06C5R)
Assuming general international transportation from Europe to Japan, we installed a mock pharmaceutical product and a logger with various sensors inside the VIXELL, which was prepared by precooling in a warehouse of a partner company in Switzerland, and conducted transportation experiments using the same air route as the actual transportation of pharmaceutical products.
In conventional constant temperature transportation of pharmaceutical products, the heat insulation performance of the cool box is poor and the temperature retention time is short, so it is necessary to fully replenish the cold insulator at the airport of departure and to reload the cold insulator at the airport of Japan in the destination country.
In the actual international transportation scene, it is often required to maintain the temperature for about 5 to 7 days, but it may exceed the planned number of days due to transshipment troubles at transit points and customs clearance troubles at the destination airport. In this experiment, we did not open the box even after arriving at the destination (Shiga Prefecture), and experimented how much the temperature could be maintained with only the first cold insulator.
As described above, this transportation experiment demonstrated that VIXELL can realize long-term cooling not only in the temperature cycle test (* see the report), which was conducted previously to evaluate the effect of external environment such as ISTA 7D, but also in the actual constant temperature transportation of pharmaceutical products.
