It does not embrittle, shatter, or develop micro-cracks during thermal cycling between room temperature and cryogenic storage. This is verified through ASTM D746 brittle point testing \u2014 PP&#8217;s brittle point is below -200\u00b0C, far below the operating range of any cryogenic storage system.<\/p>\n<p>Cardboard and foam dividers become brittle below -20\u00b0C. At -80\u00b0C (ULT freezer), cardboard cracks on contact. At -196\u00b0C (LN2), cardboard disintegrates. PP endures both environments through thousands of freeze-thaw cycles without structural degradation.<\/p>\n<h3>Zero Leachables \u2014 USP Class VI at Cryogenic Temperatures<\/h3>\n<p>USP Class VI certification (USP &lt;87&gt; and &lt;88&gt;) guarantees zero extractables and zero leachables from the divider material \u2014 even at cryogenic temperatures where some plastics release residual monomers. This is critical because stored vials may have direct contact with divider cell walls over months or years of storage. Any leachable migrating into a biological sample compromises its research validity or clinical diagnostic accuracy.<\/p>\n<p>Cardboard cannot achieve USP Class VI due to adhesives, sizing agents, and lignin-based compounds that off-gas and migrate. Foam inserts generate particulate contamination. PP is the only common divider material that meets USP Class VI biological reactivity standards.<\/p>\n<h3>Non-Porous Surface Prevents Cross-Contamination<\/h3>\n<p>PP&#8217;s non-porous surface does not absorb biological fluids, condensation, or decontamination agents. If a vial leaks, the spill is contained within the individual cell and can be wiped clean \u2014 it does not wick through the divider wall to adjacent vials as it would with cardboard or foam.<\/p>\n<p>This non-porous property also enables effective decontamination. PP cryobox dividers can be wiped with 70% ethanol, 10% bleach, or autoclaved at 121\u00b0C \u2014 standard biosafety protocols \u2014 without material degradation. Cardboard and foam cannot be decontaminated; they must be discarded after any contamination event.<\/p>\n<hr \/>\n<h2>Cryobox Dividers vs Cardboard vs Foam vs Solid Plastic Inserts<\/h2>\n<table>\n<thead>\n<tr>\n<th>Crit\u00e8res<\/th>\n<th>PP Cryobox Dividers<\/th>\n<th>S\u00e9parateurs en carton<\/th>\n<th>Inserts en mousse<\/th>\n<th>Solid Plastic Totes<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><strong>Cryogenic temp (-196\u00b0C)<\/strong><\/td>\n<td>\u2705 No embrittlement<\/td>\n<td>\u274c Cracks\/shatters<\/td>\n<td>\u274c Becomes brittle<\/td>\n<td>\u26a0\ufe0f Some grades ok<\/td>\n<\/tr>\n<tr>\n<td><strong>ULT freezer (-80\u00b0C)<\/strong><\/td>\n<td>\u2705 Full flexibility<\/td>\n<td>\u274c Cracks on contact<\/td>\n<td>\u26a0\ufe0f Partiel<\/td>\n<td>\u2705<\/td>\n<\/tr>\n<tr>\n<td><strong>Classe VI de l'USP<\/strong><\/td>\n<td>\u2705 Certifi\u00e9<\/td>\n<td>\u274c Cannot qualify<\/td>\n<td>\u274c Particulate risk<\/td>\n<td>\u2705 (if PP\/PE)<\/td>\n<\/tr>\n<tr>\n<td><strong>Contamination crois\u00e9e<\/strong><\/td>\n<td>Non-porous, spill-contained<\/td>\n<td>Wicks liquid between cells<\/td>\n<td>Absorbs fluid<\/td>\n<td>Non-porous<\/td>\n<\/tr>\n<tr>\n<td><strong>Decontamination<\/strong><\/td>\n<td>Ethanol, bleach, autoclave<\/td>\n<td>Must discard<\/td>\n<td>Must discard<\/td>\n<td>Ethanol, bleach<\/td>\n<\/tr>\n<tr>\n<td><strong>Freeze-thaw cycles<\/strong><\/td>\n<td>50\u2013200+<\/td>\n<td>1\u20133<\/td>\n<td>3\u20135<\/td>\n<td>50\u2013200+<\/td>\n<\/tr>\n<tr>\n<td><strong>Cell configuration<\/strong><\/td>\n<td>Custom die-cut any grid<\/td>\n<td>Limited to standard grids<\/td>\n<td>Mold-limited<\/td>\n<td>Mold-limited<\/td>\n<\/tr>\n<tr>\n<td><strong>Poids<\/strong><\/td>\n<td>Lumi\u00e8re<\/td>\n<td>Lumi\u00e8re<\/td>\n<td>Lumi\u00e8re<\/td>\n<td>Lourd<\/td>\n<\/tr>\n<tr>\n<td><strong>Co\u00fbt par cycle<\/strong><\/td>\n<td>$0.02\u20130.10<\/td>\n<td>$ 0,50\u20132,00<\/td>\n<td>$0.30\u20131.00<\/td>\n<td>$0.05\u20130.20<\/td>\n<\/tr>\n<tr>\n<td><strong>Recyclable<\/strong><\/td>\n<td>\u2705 PP #5<\/td>\n<td>\u26a0\ufe0f Contaminated<\/td>\n<td>\u274c<\/td>\n<td>\u2705<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><strong>The decision is clear:<\/strong>\u00a0For any facility storing vials at -80\u00b0C or below, PP cryobox dividers are the only option that maintains structural integrity, biological safety, and decontamination capability simultaneously.

PP cryobox dividers create organized grids that map directly to inventory management systems \u2014 every cell position corresponds to a database entry, enabling rapid sample location and retrieval.<\/p>\n<p>Compliance: ISO 20387 (Biobanking), ISBER Best Practices, NCI Best Practices for Biospecimen Resources.<\/p>\n<h3>Clinical Trials &amp; Pharmaceutical R&amp;D<\/h3>\n<p>Clinical trial specimens (blood draws, urine samples, tissue biopsies) are collected at study sites, aliquoted into vials, and shipped on dry ice to central laboratories. Cryobox dividers keep each patient&#8217;s samples separated and identifiable during frozen transit and storage.

Chaque flacon est log\u00e9 dans son propre compartiment individuel, ce qui \u00e9vite les dommages dus aux contacts, l'usure des \u00e9tiquettes et les confusions entre \u00e9chantillons.

Whether your vials are stored in ULT freezers at -80\u00b0C or submerged in LN2 dewars at -196\u00b0C, PP cryobox dividers perform identically on day 1 and day 200.<\/p>\n<p><strong>Q: What is the difference between cryobox dividers and PP corrugated dividers?<\/strong><\/p>\n<p>Les s\u00e9parateurs Cryobox et les s\u00e9parateurs en polypropyl\u00e8ne ondul\u00e9 sont tous deux des inserts en forme de grille de cellules d\u00e9coup\u00e9s \u00e0 l'emporte-pi\u00e8ce, mais ils sont destin\u00e9s \u00e0 des applications diff\u00e9rentes. Les s\u00e9parateurs Cryobox sont con\u00e7us pour les flacons soumis \u00e0 des temp\u00e9ratures cryog\u00e9niques (de -80 \u00b0C \u00e0 -196 \u00b0C) dans le cadre de la conservation de biobanques et de la recherche clinique ; ils doivent \u00eatre certifi\u00e9s USP Classe VI et ne pr\u00e9senter aucun risque de lixiviation.

Si vous stockez des flacons \u00e0 des temp\u00e9ratures inf\u00e9rieures \u00e0 -20 \u00b0C, vous avez besoin de s\u00e9parateurs pour cryobox.

Le carton ondul\u00e9 en PP ne se fragilise pas, ne se fissure pas et ne se d\u00e9grade pas lorsqu\u2019il est immerg\u00e9 dans l\u2019azote liquide ni lorsqu\u2019il est soumis \u00e0 des cycles de passage de l\u2019azote liquide \u00e0 la temp\u00e9rature ambiante lors du retrait des \u00e9chantillons. C'est l\u00e0 leur principal avantage par rapport aux s\u00e9parateurs en carton (qui se brisent \u00e0 -196 \u00b0C) et aux inserts en mousse (qui deviennent cassants et g\u00e9n\u00e8rent une contamination particulaire).<\/p>\n<p><strong>Q: Can cryobox dividers be autoclaved for sterilization?<\/strong><\/p>\n<p>Yes. PP cryobox dividers can be autoclaved at 121\u00b0C, 15 psi for 30 minutes without dimensional change or structural degradation. They are also compatible with gamma irradiation (25 kGy) and EtO gas sterilization. This three-method sterilization compatibility allows cryobox dividers to be decontaminated between uses in biosafety level (BSL) environments, unlike cardboard or foam, which must be discarded after contamination events.<\/p>\n<p><strong>Q: What vial sizes and cell configurations are available?<\/strong><\/p>\n<p>PPBOXY propose des s\u00e9parateurs pour cryobox destin\u00e9s aux flacons de 2 ml \u00e0 50 ml. Les configurations standard comprennent des grilles \u00e0 9 alv\u00e9oles (3\u00d73), 25 alv\u00e9oles (5\u00d75), 81 alv\u00e9oles (9\u00d79) et 100 alv\u00e9oles (10\u00d710). Des tailles de compartiments personnalis\u00e9es, des sch\u00e9mas de grille sur mesure et des configurations mixtes (compartiments de tailles diff\u00e9rentes dans un m\u00eame s\u00e9parateur) sont disponibles pour les types de flacons non standard. Les dimensions standard des cryobox sont de 133 \u00d7 133 mm (2\u2033 \u00d7 2\u2033) et 270 \u00d7 270 mm. Tous les s\u00e9parateurs sont d\u00e9coup\u00e9s sur mesure en fonction des dimensions exactes de vos flacons et de l\u2019int\u00e9rieur de votre cryobox \u2014 il vous suffit de nous indiquer le diam\u00e8tre et la hauteur de vos flacons, ainsi que les dimensions internes de la bo\u00eete.<\/p>\n<p><strong>Q: How do cryobox dividers prevent cross-contamination?<\/strong><\/p>\n<p>Le carton ondul\u00e9 en PP pr\u00e9sente une surface non poreuse qui n\u2019absorbe ni les fluides biologiques, ni la condensation, ni les agents de d\u00e9contamination. En cas de fuite d\u2019un flacon, le liquide d\u00e9vers\u00e9 est confin\u00e9 dans la poche individuelle de la cellule et peut \u00eatre essuy\u00e9 \u2014 il ne s\u2019infiltre pas \u00e0 travers la paroi de s\u00e9paration vers les flacons adjacents.
