Background<\/strong><\/span><\/p>\n

Charles River Laboratories is a leading global provider serving pharmaceutical, biotechnology, agrochemical, government, and academic organisations. Their expertise spans the entire drug discovery and development process, supporting laboratories with critical sample handling and storage solutions.<\/span><\/p><\/blockquote>\n

\n

Challenge
\n<\/b><\/span><\/strong><\/span>Charles River Laboratories required a durable cryogenic label<\/strong> solution for polypropylene cryovials stored at extreme temperatures between -60\u00b0C and -90\u00b0C<\/strong>. These labels also needed to withstand exposure to citric acid, methanol, and other solvents<\/strong> used in their toxicology and specialist studies.<\/p>\n

Their previous labels were failing: with 4,000\u20136,000 <\/strong>sample ID labels<\/u><\/a><\/span> applied daily<\/strong>, poor adhesion led to labels peeling off, creating additional work and risking sample misidentification. The laboratory needed a thermal transfer printable cryogenic label<\/u><\/a> <\/span>that would:<\/p>\n

–<\/b><\/span><\/strong> Remain adhered during long-term cryogenic storage
\n–<\/b><\/span><\/strong> Resist common laboratory solvents
\n–<\/b><\/span><\/strong> Ensure high readability and durability for sample tracking<\/p>\n

Solution
\n<\/b><\/span><\/strong><\/span>CILS introduced its CRYO -80\u00b0C PLUS labels<\/strong>\u00a0\u2013 premium polyester labels engineered for extreme freeze and dry ice storage. Samples were provided for testing under real laboratory conditions, demonstrating:<\/p>\n

–<\/strong> <\/span>Strong adhesion to polypropylene cryovials at -80\u00b0C
\n–<\/b><\/span><\/strong> Resistance to acids and methanol
\n–<\/strong><\/span> Durability during repeated handling and thermal cycling<\/p>\n

The solution included compatible thermal transfer ribbons<\/span><\/u><\/a><\/span> to ensure clear, long-lasting print for sample IDs.<\/p>\n

Results
\n<\/b><\/span><\/strong><\/span>Following successful validation, Charles River Laboratories adopted CILS CRYO -80\u00b0C PLUS labels<\/strong> across their facility. Benefits included:<\/p>\n

–<\/b><\/span> Reliable adhesion<\/strong> for the full lifespan of stored samples
\n–<\/b><\/span> Reduced relabeling and duplication of work<\/strong>, improving productivity
\n–<\/b><\/span> Solvent-resistant performance<\/strong>, protecting sample integrity
\n–<\/b><\/span><\/strong> Confidence in global scalability, as CILS is now supporting multiple Charles River sites<\/p>\n

By choosing CILS, Charles River Laboratories secured a robust cryogenic labelling solution<\/strong> that enhances sample management efficiency and ensures reliable identification in demanding laboratory environments.<\/p>\n
