Cell-Free DNA Preservation Tube

Product Highlights

• Specialized preservation formulation with an EDTA salt
• Glass tube configurations listed by draw volume and dimensions
• Dedicated pre-analytical workflow distinct from standard EDTA collection

Structure & Functional Design

The EDTA-based preservation formulation is designed for cell-free DNA sample workflows. The glass body and capped rubber-stopper closure provide a dedicated collection format. Preservation limits and downstream processing conditions are specific to the supplied formulation.

Applications

For validated cell-free DNA collection and downstream laboratory workflows. Suitability for a particular diagnostic application or extraction system must be established for the supplied product.

Technical Specifications

Ordering Information

Specify the additive, tube material, dimensions, required draw volume and order quantity. Each table row shows the corresponding size, capacity and packing combination. Request the item specification, labeling details and supplied instructions with the quotation.

Handling & Storage

• For use by trained personnel. Check the tube identity, packaging integrity and expiry information before use.
• Follow the supplied collection, mixing and processing instructions. Fill to the specified volume; use the validated clotting and centrifugation conditions where applicable.
