Why use COP polymer vials for cryogenic storage packaging evaluation?
COP polymer vials are considered for cryogenic storage packaging evaluation because they offer high transparency, break resistance and low protein adsorption concern. These points are important when customers compare polymer vials with conventional glass containers for sensitive sample storage projects.
Can COP vials be used at -196 C?
COP vials can be discussed for cryogenic storage condition evaluation, including project discussion around -196 C where applicable. Final suitability should be validated with the customer's formulation, closure system, storage process and testing plan.
What vial size should be used for cryogenic storage projects?
2ml,5ml,10ml COP vials are commonly discussed for small-volume cryogenic storage packaging evaluation. Customers can also discuss other project sizes according to filling volume, closure matching and storage requirements.
Are COP vials suitable for cell and gene therapy packaging projects?
COP polymer vials can be evaluated for cell and gene therapy packaging projects where break resistance, visual inspection, low-temperature storage and sensitive material handling are important packaging considerations.
