Sodium Citrate ESR Blood Collection Tube

Product Highlights

• Citrate additive for ESR sample preparation
• Slender long-tube and standard-diameter configurations
• Black closure styles vary with the tube construction

Structure & Functional Design

The tube contains 3.8% sodium citrate for ESR sample preparation. Slender long-tube and standard-diameter configurations use different dimensions and closure designs. Select the collection tube together with its matched rack and measurement procedure.

Applications

For ESR testing with a matched collection tube, rack and validated method. Do not substitute a coagulation tube or assume every tube works in a generic Westergren rack.

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

Can this replace a citrate coagulation tube?

No. ESR and coagulation workflows use different tube specifications and may require different citrate concentrations and blood-to-additive ratios.

Will both tube shapes fit the same ESR rack?

Not necessarily. Match the tube diameter, length and measurement procedure to the rack and its instructions.

Is nominal liquid capacity the blood draw volume?

No assumption should be made that these values are the same. Use the blood draw volume and fill mark stated on the supplied tube label and instructions.
