A Cool Cube™ at Controlled Room Temperatures is not an ordinary transport cooler (FFPE, platelets and biospecimens carrier). It is an easy-to-carry, qualified container and pack-out system that keeps temperature sensitive product (FFPE, platelets, biospecimens) between 15° and 25°C for over 2.5 days – without using ice or electricity! This cooler is ideal for transport, but also excels at protecting valuable product during off-site use and power outages, regardless of hot or freezing conditions. The simple, validated, patented technology is the best compact thermal protection product available to maintain the cold chain!
Transport & Storage Coolers @ Room Temps for FFPE, Platelets, Biospecimens, etc.

Room Temperature Cool Cube™ Prep Methods
Series 22 Prep Method: A – Lab Incubator Prep to keep product cool
Prep Time: Stage 1 ≈ 3 hours / Stage 2 (prior to pack-out) none
Panel Prep Stages (lab incubator)
1. Store panels in a lab incubator (or other 15-20°C environment) so PCM (phase change material inside the panel) is solid (i.e. 24 hrs. @ 15°C). Shake to verify.
Before assembly, shake panels to estimate the state of the PCM. Solid PCM panels will keep product cool in extreme heat the longest. Liquid PCM panels may be used but hold times will decrease.
Series 22 Prep Method: B – Fridge/Room Prep to keep product cool
Prep Time: Stage 1 ≈ 2 hours / Stage 2 (prior to pack-out) ≈ 2 hours
Panel Prep Stages (fridge to room)
1. Store panels in a fridge so PCM (phase change material sealed inside the panel) is solid. Shake to verify.
- i.e. 2 hrs. @ 4°C turns PCM solid
2. Transfer panels into a fridge 2 hours prior to use to allow PCM inside to rise to the appropriate operating temperature.
Before assembly, shake panels to estimate the state of the PCM. Solid PCM panels will keep product cool in extreme heat the longest. Liquid PCM panels may be used but hold times will decrease.
Series 22 Prep Method: C – Lab Incubator Prep to keep product warm
Prep Time: Stage 1 ≈ 3 hours / Stage 2 (prior to pack-out) none
Panel Prep Stages (lab incubator)
1. Store panels in a lab incubator (or other 23-25°C environment) so PCM (phase change material inside the panel) is liquid (i.e. 24 hrs. @ 25°C). Shake to verify.
Before assembly, shake panels to estimate the state of the PCM. Liquid PCM panels will keep product warm in cold conditions the longest. Solid PCM panels may be used but hold times will decrease.
Series 22 Prep Method: D – Room Prep to keep product warm
Prep Time: Stage 1 ≈ 3 hours / Stage 2 (prior to pack-out) none
Panel Prep Stages (room)
1. Store panels in a room temperature environment that is warmer than 22°C but cooler than the warmest temperature needed.
Before assembly, shake panels to estimate the state of the PCM. Liquid PCM will keep product warm in cold conditions the longest. If PCM has started to solidify, panels may be used but hold times will decrease.
About Series 22 PCM Passive Temperature Technology
Phase change materials (PCMs) are materials that absorb and release thermal energy during the process of melting and freezing. When a PCM melts, it absorbs the heat from the environment, yet its temperature stays at the melting point until totally liquid. Conversely, when a PCM freezes, it absorbs the cold from the environment, yet stays at its temperature until totally solid. This makes PCM an ideal, passive solution for a variety of applications that require temperature control. The most common PCM is water/ice. Ice is an excellent PCM for maintaining temperatures at 0°C. But water’s freezing point is fixed at 0°C (32°F), which makes it unsuitable for most temperature sensitive applications.
Cool Cube™ PCMs offer custom temperature holds based on their melting point. The PCM inside Series 22 panels has a melting point of 21.5°C/70.7°F. When panels are solid, contents within the Cool Cube™ stay at room temperature (around 21.5°C) in hot conditions during an extended period of time. When panels have liquid inside, contents within the Cool Cube™ won’t get cold (again at room temps around 21.5°C) in cold conditions during an extended period of time.
Room Temps Temps Hold Time:
- Always prep the PCM panels before use according to one of the described methods provided by VeriCor.
- Ensure all components are clean and free of damage.
- During prep, enable ample air flow around all panel sides (use spacers or racks).
- Lay panels flat when “freezing”.
- Freeze/melting times vary depending on number of panels being prepped and equipment specifications being used. Assemble using all six panels for maximum hold time.
- Using less panels does not change the holding temperature but does decrease hold time.
- Panels are reusable (10,000+ cycles). (End-of-life disposal: panels use a plastic #2, typically recycled by businesses/communities; PCM is nontoxic and readily biodegradable.)
- Use a calibrated data logger or other temperature monitoring device to observe internal temperature.
- Avoid unnecessary opening of the Cool Cube™ after loading payload. Opening of the Cool Cube™ will decrease hold time.
- An infrared temperature thermometer can assist in ensuring the panels reach a safe pack-out temperature (good for finding out the approximate temperature of each panel).
- Further the temps are away from the melting point, the quicker PCM will change states.
