PRODUCT DETAILS

Product Highlights

No added anticoagulant, clot activator or gel
Transparent round-bottom tube for sample visibility
Plain-tube configuration distinct from clot activator and separator gel tubes

Structure & Functional Design

The tube uses a capped rubber-stopper closure and a transparent body. No anticoagulant is included, so a no-additive tube must not be treated as an EDTA, heparin or citrate whole-blood tube. Glass and PET configurations should be selected according to the collection and assay procedure.

Applications

For laboratory collection procedures that specifically require a plain no-additive tube. Serum preparation and clotting requirements depend on the selected material and the applicable laboratory procedure.

Frequently Asked Questions

Is a red cap enough to identify a no-additive tube?

No. Cap colors vary between manufacturers and product lines. Identify the tube from its additive label and item specification.

Is this the same as a clot activator tube?

No. A no-additive tube contains no added clot activator; do not assume the same clotting time or processing conditions.
