Yes. Please contact us for the MSDS for further information. We only use food-grade oils and non-toxic colourants in our formulation.
In the unlikely event that the liquid leaks from the indicator and comes into contact with skin, simply wash with soap and water. If the liquid comes into contact with eyes, rinse immediately with plenty of water and seek medical advice.
Yes. The temperature thresholds and time marker specifications can be adjusted. It also possible to change the graphic to incorporate customer colours and logos. All custom orders are subject to a minimum volume and the cost and specification will depend on what is required and feasible. Please contact us for more information.
adminCan Duo be customised for different time markers and temperature thresholds?
The Accepted Failure Rate is based on ANSI/ASQC Z1.4 (formally MIL-STD-105E) Level II Normal Inspection. For Duo the AQL is 0.65%. Packs are over shipped by 2-3 units per 100 to cover this AQL.
Duo indicators go through extensive quality checks before they are shipped. Central to this process are tests against defined specifications for; run-time accuracy (how quickly the dye progresses through the membrane), environment sensitivity (high heat and vacuum tests to check resilience to harsh conditions during shipping) and also the accuracy of the threshold melting point. A full pack of release reports is provided with each shipment. Further details are available on request.
+/- 1˚C for each temperature component and +/- 15% for each time component.
The run rate of the blue dye across the time markers is calibrated to a temperature of 2˚C above the stated threshold temperature. For example, the time markers for the 10˚C threshold indicator in Duo are calibrated to a temperature of 12˚C/54°F. If the vaccine being monitored breaches its threshold temperature and is held at a constant temperature (i.e. isotherm) of 12˚C, the blue mixture will reach the 3 day print mark within 3 days (+/- 15% in time).
