PRODUCT DETAILS

Product Highlights

Sodium citrate anticoagulant for coagulation sample preparation
Single-wall and double-wall tube constructions are separate configurations
Fill-volume identification is essential to the required blood-to-additive ratio

Structure & Functional Design

The liquid sodium citrate additive binds calcium reversibly to maintain an anticoagulated sample for coagulation testing. Single-wall and double-wall configurations are listed separately. Correct filling is essential to the required blood-to-additive ratio; use the labeled blood draw volume and fill mark, which are distinct from nominal liquid capacity.

Applications

For citrate-plasma coagulation tests when accepted by the assay and collection procedure. Confirm the required citrate concentration, draw volume and tube construction before ordering.

Technical Specifications

The table lists nominal liquid capacity. For collection, use the labeled blood draw volume and fill mark specified for the supplied tube.

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.
Keep unused tubes in their original packaging under the labeled storage conditions. Follow the assay-specific limits for specimen transport and storage.
Handle used tubes and blood specimens as potentially infectious and dispose of them according to laboratory requirements.

Frequently Asked Questions

Is nominal liquid capacity the blood draw volume?

Not necessarily. Nominal liquid capacity may include the additive. Use the supplied tube’s stated blood draw volume and fill mark; do not calculate it from a catalog code.

Are coagulation citrate tubes interchangeable with ESR tubes?

No. They are intended for different procedures and can have different citrate concentrations and blood-to-additive ratios.
