Cube – Relaxed traveling, even with medications requiring refrigeration

The Cube is a medicine box including cold packs and carrying bag, specially designed to be carried in your hand luggage during the flight. The box allows you to travel uncomplicated and safely with your refrigerated medications.

The special cold packs (PCM) of the Cube allow cooling in the temperature range between 2° & 8°C. Unlike conventional batteries, they keep the temperature exactly within this range. So you can be sure that your medicines neither freeze nor get too warm.

The insulation of the cube ensures a long runtime of at least 60 hours (in the worst case), so you don’t have to worry about your medication at any time during your flight. Check the temperature at any time easily via the app on your smartphone by scanning the QR code of the included temperature gauge.

The Cube System is a cooperation between the Lufthansa Group and Tec4med. You will receive the system with an enclosed form for “taking along a Tec4med bag free of charge as additional hand luggage for refrigerated medications”. Keep this form handy when boarding the flight and show it upon request.

Please note: We can only guarantee that you can take your Tec4med bag on Lufthansa Group flights free of charge. (Lufthansa German Airlines, SWISS, Austrian Airlines und Brussels Airlines)

Before traveling, talk to your doctor about the amount and type of medication to be taken. Your doctor will also provide you with a medication plan for the trip upon request. Be aware of possible time changes in other countries. Also, if possible, take a little more than the required amount of the medication with you so that you have a reserve for unforeseen events.

Medication may also be carried in hand luggage in larger quantities than the usual 100ml for liquids. Also syringes (which are considered dangerous objects), as well as narcotics or strong painkillers, you may take in your hand luggage. In any case, however, there must be a medical necessity. In order to avoid possible misunderstandings with the security personnel in advance, we recommend that you consult your doctor. He or she can issue a medical certificate for the trip.

The Cube is specially designed for use in hand luggage. You only need to ensure that the cold packs have been properly prepared. To do this, pre-cool the batteries for at least 8 your in their freezer (usually -18° C). Note that each freezer device is different, and the prepare-time may differ.

Note: The liquid in the cold packs should be solid after cooling, only then the cold pack is frozen and ready for use. Allow the cold packs to defrost before use. Once the indicators on the packs change color and the hook becomes visible (approx. 30 minutes) placing the drugs in the Cube is possible. This way, you prevent the medications from freezing.

Hint: Simply use the TempBeacon (thermometer) to check your temperature in the refrigerator. Using the Tec4App (available on Android and iOS), this can be read on any cell phone and the temperature can be tracked in your app. This way you can ensure that the cold packs have been pre-cooled at the correct temperature for the correct period of time to guarantee the maximum runtime.

The Cube will maintain the temperature of 2° – 8 °C for at least 60 hours regardless of whether the outside temperature is higher or lower. Note, however, that this is for a closed Cube. Therefore, never open the lid more than necessary to guarantee the longest possible runtime.

With the Cube system, you also receive a temperature data logger and access to the associated app. You can simply read it out with your smartphone via a QR code scan. In the app, we show you the measured temperature and warn you if the temperature is exceeded. You can also conveniently download the measured data in a log as a PDF.

Note: Place the TempBeacon near the medicine inside the cube. This way you will get the most accurate result of the temperature measurement.

In this case, contact the manufacturer of the drugs and ask for stability data of the respective drug. You can also download the temperature report from the Tec4App and send it to the manufacturer for verification if necessary.

You can rent the Cube for as long as you like. The shortest rental period is 7 days.

The Cube is conveniently delivered to your home (delivery at least 2-3 business days before your departure). You will receive it via your local parcel delivery service. So you can prepare the cold packs in the fridge in time before your trip. You will also receive a tracking link to trace your shipment when it is shipped.
