About Lab Freezer PCM (Phase Change Material)

PCM absorbs and releases thermal energy during the process of melting and freezing. When solid PCM melts, it absorbs the heat from the environment, yet its temperature stays at the melting point until totally liquid. Conversely, when liquid PCM freezes, it absorbs the cold from the environment yet stays at its temperature until totally solid. Therefore, PCM an ideal, passive solution for a variety of applications that require temperature control. The most common PCM is water, which has a melting point of 0 °C (32 °F). When solid, ice/water maintains a temperature of 0 °C until it turns completely liquid. So, in essence, the 0 °C melting point makes it unsafe for most frozen temperature-sensitive applications.

Cool Cube™ Lab Freezer PCM has a melting point of -21.5 °C/-6.7 °F. When the PCM is solid, a panel helps the Cool Cube™ stay cool (about -21 °C) in warm/hot environments. It’s right around that -21.5 °C/-6.7 °F where a PCM panel’s temperature plateaus for a while during the warming up and/or cooling down processes.

Lab Freezer - Prep Method A - Ultra-Low Freezer Prep to keep product frozen

Prep Method A: Ultra-Low Freezer Prep to keep product frozen

Panel Prep

2.1 Lay panels flat in an ultra-low freezer until all the PCM (phase change material inside the panel) turns solid. At -25°C/-13°F the PCM will solidify in a day or two.*

    * If the freezer temperature is ever warmer than -25°C, PCM may not get completely solid (due to the possibility of supercooling). If panels are stored within the temperature parameters of the product but the PCM is liquid, panels may be used but the hold time will decrease.

Shake PCM Panel To Check

2.2 Shake panels to verify the PCM is solid. If there is liquid, restart at step 2.1 to ensure the longest hold time. Using liquid PCM or panels with a solid/liquid combination decreases the hold time.


Lab Freezer - Prep Method B - Dry Ice-Freezer Prep to keep product frozen

Prep Method B: Dry Ice Prep to keep product frozen

Panel Prep

2.1 Pack out cooler with dry ice until the PCM (phase change material inside the panel) panels become solid. The more dry ice, the faster the PCM will solidify.*

    * Time varies dependent on the starting temperature of the panels, size of panels, and amount of dry ice used. CAUTION: Dry ice has a surface temperature of -78.5°C/-109.3°F, so handle with care.

2.2 (Optional) If product to be packed out cannot withstand an initial -70°C temperature, transfer panels into a standard freezer at least 3 hours before use. Panels may be stored in the freezer until needed for assembly or the PCM melts.

If a freezer maintains -23°C or below, the PCM within the panels will not melt (melting point is -21.5°C), keeping the PCM solid indefinitely until pack-out. If the freezer maintains -21.5°C or above, periodically check for melting and restart at step 2.1 to ensure the longest hold time.

Shake PCM Panel To Check

2.3 Shake panels to verify the PCM is solid. If there is liquid, restart at step 2.1 to ensure the longest hold time. Using liquid PCM or panels with a solid/liquid combination decreases the hold time.



Lab Freezer - Prep Method C - Standard Freezer Prep to keep product frozen

Prep Method C: Standard Freezer Prep to keep product frozen

Panel Prep

Store panels in a standard freezer (turned down to its lowest setting) for a minimum of 24 hours before use. Unless the freezer is always below -23°C, the PCM (phase change material inside the panel) will never turn completely solid, but short-term use is still possible.*

    * Although PCM is liquid, it is at the temperature of storage environment after 3 hours. For instance, panels stored in a -18°C freezer are at -18°C even PCM is liquid. Assembling the Cool Cube™ with this additional thermal mass will keep product frozen, just for a shorter amount of time than the lab-validated results.

Shake PCM Panel To Check

Shake panels to check the state of the PCM (phase change material inside the panel).

          • If liquid…panel is at the freezer temp but above -20°C; anticipate shorter hold times.

          • If solid…panel is at the freezer temp but below -23°C; ideal for maximum hold times.

          • If solid/liquid combination…panel is at the freezer temp between -23 and -20°C; monitor longer use periods.

Thermal Properties of Series 20M PCM Panels

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 Lab Freezer panels has a melting point of -21.5°C/-6.7°F. When panels are solid, contents within the Cool Cube™ stay frozen (at freezer temps around -21.5°C) in hot conditions during an extended period of time. If panels have liquid inside, PCM is at the temperature of the storage environment, but will not prevent warming in hot conditions as effectively as solid panels.

PCM Panel Prep Steps Sequence

PCM Panel Spacing Customer Solution

      • 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.

FT-28 Specific FAQ

The FT-28 when properly conditioned will last 94+ hours.
  1. Store panels in an ultra-low freezer* so PCM is solid (i.e. 24 hrs. @ -25°C).
  2. Before assembly, shake panels to verify PCM is solid. If liquid is heard, restart at step 2a to ensure longest hold time. Using liquid panels, or panels with a solid/liquid combination, deceases hold time
* If the freezer temperature is ever warmer than -25°C, panels may not turn completely solid (due to the possibility of supercooling). If panels are stored within the temperature parameters of the product, but are still liquid, panels may beused but the hold time will decrease
Store in coldest area of freezer; space out panels for good air flw; if stacking, insert a spacer (pencil, tongue depressor, etc.) in between each.

The time varies between prep methods:

    • Method A: ≈ 24 hours
    • Method B: ≈ 3 hours
    • Method C: ≈ 24 hours

In the user guide we recommend Method A, although all methods work. Choose the method that works best with your schedule and available resources.

If you store the PCM panels in your freezer they will be available to use whenever you need them. Shake the panels to see if they are solid. If they are slushy your freezer is not cold enough. If the panels are slushy they will still work, but the hold times will be decreased.

Prep Method A:

  1. Store panels in an ultra-low freezer* so PCM is solid (i.e. 48 hrs. @ -30°C).
  2. Before assembly, shake panels to verify PCM is solid. If liquid is heard, restart at step 2a to ensure longest hold time. Using liquid panels, or panels with a solid/liquid combination, deceases hold time
* If the freezer temperature is ever warmer than -30°C, panels may not turn completely solid (due to the possibility of supercooling). If panels are stored within the temperature parameters of the product, but are still liquid, panels may beused but the hold time will decrease.

Frozen Temperatures Specific Cool Cubes™

Your freezer must be below at least -15°C. -25°C or below is recommended to get the panels solid (for maximum hold time). The colder the storage environment, the less time is needed to condition the panels for use.
The PCM inside is NOT below its phase change temperature of -21.5°C/-6.7°F. Make sure that the freezer temperature is always below -23°C/-9.4°F.
Yes, but to get the panels truly hard, the freezer must maintain a temperature lower than -30°C. Otherwise, the panel will be at the temperature of the freezer (in a liquid state) and just won’t last as long.

Yes. The panels can be stored in a freezer for as long as you wish. If stored in the freezer they will be ready for use whenever you need them.

  • Only store the PCM panels in the freezer. It is not necessary to condition the VIP container.
  • Make sure to shake the panels to see if they are solid. If they are not solid your refrigerator is not cold enough. If the panels are still slushy they will still work, but they will not hold product for the optimum time frame.

    All components are available for purchase.
    A plastic panel filled with phase change material. Each Cool Cube™ comes with 6 PCM panels that make up the PCM System.
    The VIP (Vacuum Insulation Panel) System consists of 6 panels that form an insulation barrier for the Cool Cube™. Each panel is a specially formed rigid foam board, shrink wrapped, encased in a metallic plastic film, and sealed under vacuum.
    Phase Change Material – a substance with a high heat of fusion which, melting and solidifying at a certain temperature, is capable of storing and releasing large amounts of energy.
    Vacuum Insulation Panel – a form of thermal insulation consisting of a gas-tight enclosure surrounding a rigid core, from which the air has been evacuated.

    Conditioning

    The PCM inside is NOT below its phase change temperature of 21.5°C/70.7°F. Make sure that the storage temperature is always below 20°C/68°F.
    The PCM inside is NOT below its phase change temperature of 4.5°C/40.1°F. Make sure that the storage temperature is always below 4°C/39.2°F.
    The PCM inside is NOT below its phase change temperature of -21.5°C/-6.7°F. Make sure that the freezer temperature is always below -23°C/-9.4°F.
    Yes, for Cool Cubes™ at Fridge Temps. However, before pack-out, the panels must sit out and warm up until they “sweat” so that they don’t make the cooler too cold.
    Yes, for Cool Cubes™ at Fridge Temps. Make sure the refrigerator temperature is below 4°C to ensure panels turn solid (the closer the fridge is to 4.5°C, the longer it will take to turn solid).
    Yes, but to get the panels truly hard, the freezer must maintain a temperature lower than -30°C. Otherwise, the panel will be at the temperature of the freezer (in a liquid state) and just won’t last as long.
    Yes, but they will just take longer to condition (the middle panel will be the last to condition). For the quickest conditioning process, get as much air circulating around the panel as possible.
    If the panels must be stacked we recommend inserting a spacer (pencil, tongue depressor, etc.) between each panel.
    No, but the PCM panels need to be prepped.
    The PCM inside is above its phase change temperature.
    No. It is not necessary to condition the vacuum insulated panel (VIP) system. Storage at room temperature is recommended.

    Maintenance

    With the two smaller models the fabric case can be hand-washed and air-dried. With the hard-sided models the case can be wiped down.

    Pack Out

    Vacuum Insulation Panel – a form of thermal insulation consisting of a gas-tight enclosure surrounding a rigid core, from which the air has been evacuated.
    No, but all six panels will maintain a consistent temperature the longest. The fewer the panels, the shorter the temperature holding time.
    No. The PCM panels are replacements superior to the standard gel pack method of cooling.
    No. The PCM panels are replacements superior to the standard ice pack method of cooling.
    Not during use. But during storage/conditioning, electricity may be needed to maintain condition the panels properly.
    Yes. The large cooler can be locked with a small, steel padlock. The small and medium coolers have double zippers that can be fastened together with a small, cable padlock.
    Yes, if they have the same temperature parameters. No, if they require two different parameters.
    Yes, just not at the same time. Temperature controlling panels (the PCM System) can be purchased separately and swapped out depending on use.
    No. Although it is recommended to have a thermometer to monitor the temperature and some filler material (newspaper, bubble-wrap, etc.) to prevent contents from shifting.
    The “series” and color codes are: Series 4 (blue tab) maintains a refrigerated temperature. Series 20M (black tab) maintains a frozen temperature. Series 22 (tan tab) maintains a room temperature.
