Cryo Coders

GISCOM Cryo Coders are colour-coded inserts designed to fit securely into the caps of cryogenic vials, offering a simple yet highly effective way to identify, organise, and differentiate frozen samples. These coders enhance traceability during cryogenic storage, helping laboratories maintain clear sample segregation even under ultra-low temperatures. Their compatibility with leading cryo vial formats makes them an essential accessory in biobanking, research, and long-term sample preservation workflows.

Key Features

• Colour-Coded Identification: Enables quick visual differentiation of sample sets, batches, or projects.
• Precision Fit: Designed to lock firmly into cryo vial caps without slipping or deformation.
• High Durability at Low Temperatures: Maintains integrity in cryogenic environments, including vapour-phase LN₂ storage.
• User-Friendly Organisation: Reduces sample-handling errors and enhances workflow efficiency.
• Chemical-Resistant Surface: Withstands routine laboratory chemicals, ensuring longevity and clean usage.
• Lightweight & Non-Contaminating: Does not interfere with vial sealing or sample sterility.
• Multiple Colour Options: Enables flexible coding systems tailored to institutional or project-specific requirements.

Handling & Precautions

• Insert the coder firmly into the cryo vial cap before freezing.
• Avoid exposure to extreme heat; not suitable for autoclaving or dry heat sterilisation.
• Clean gently with mild laboratory detergents; avoid abrasive chemicals.
• Do not force-fit into incompatible caps to prevent cracking.
• Store in a clean, dry environment to maintain colour and structural integrity.
• Use standardised colour-coding protocols to ensure consistent lab practices.

Applications

• Biobanking & Cryogenic Storage: Long-term sample grouping and identification.
• Pharmaceutical R&D & QC Labs: Clear batch separation for frozen compounds or cells.
• Biotechnology & Life Sciences: Easy recognition of experimental sets during cryogenic workflows.
• Clinical & Diagnostic Laboratories: Efficient management of patient or research sample categories.
• Academic & Research Institutes: Organised storage of cell lines, microbial stocks, and biological samples.

Cryo Coders streamline daily laboratory operations by reducing identification errors, simplifying retrieval, and improving traceability in low-temperature environments.
