How to Choose EDTAK3 for Venous and Capillary Blood Collection

Choose EDTAK3 by matching the collection route, hematology test, additive, tube material, vacuum specification, sterilization method, shelf life, and packaging format. This guide explains where the series fits, which details affect routine sample handling, and how to shape a purchase request for laboratories using venous or capillary blood collection workflows.

The purchase decision starts with the collection route and the test workflow. Our EDTAK3 series is intended for venous and capillary blood collection for hematology applications, including Complete Blood Counts (CBC). It uses K3-EDTA and medical-grade PET, with vacuum collection, gamma irradiation, a 24 Months shelf life, and customized bulk or rack packaging.

Match the tube to the collection workflow

EDTAK3 fits laboratories that collect venous or capillary blood for hematology testing. K3-EDTA is the additive type, so the tube suits workflows that require anticoagulated blood during transport and analysis. If your collection program serves both standard blood draws and smaller-sample settings, the same series can cover those two routes.

The series is designed for automated laboratory centrifuges and analyzers. Make equipment fit part of the order review: compare the tube format with the holders, centrifuges, and analyzers already used in your laboratory. This check is especially useful when several collection rooms send samples to one processing area.

Check the construction and identification features

Medical-grade PET gives the tube high transparency, allowing staff to inspect the sample visually during receiving and handling. That makes the material a practical check for laboratories where sample visibility matters during routine processing.

The additive designation is K3-EDTA. Keep that wording consistent across the purchase specification, tube coding, and hematology workflow so the selected tube matches the laboratory's internal identification system.

Standardized cap color coding supports quick recognition during collection and sorting. The labeling is compatible with high-resolution barcodes for sample identification and tracking. Laboratories using a Laboratory Information System can include barcode readability and label position in their incoming inspection checklist.

Review vacuum, sealing, and storage controls

EDTAK3 uses rapid vacuum collection with a high-precision vacuum degree of ±10%. Include the required blood volume and this vacuum specification in the purchase review when consistent collection is part of your process.

An airtight cap helps control leakage during routine handling and transport. Gamma irradiation is used for sterilization, which should be included in the handling specification for collection points that move tubes to another laboratory area or facility.

The shelf life is 24 Months. Use it to set stock rotation and batch receiving controls. Record the batch on arrival and issue earlier batches before later deliveries so inventory follows a first-in, first-out arrangement.

Select the supply format

Customized bulk or rack packaging gives you two ways to organize distribution. Bulk packaging suits operations with higher quantities and an established sorting process. Rack packaging suits laboratories that stage tubes for bench collection and organized dispensing.

Choose the format according to storage space, collection volume, and the way staff issue tubes. A distributor or laboratory group supplying several collection rooms can also specify whether every location uses one pack format or whether different rooms need different handling arrangements.

Traceable labeling and batch inventory control support receipt, storage, and issue records. Define the label information and batch fields your team uses before requesting the packaging format, especially when multiple tube batches are held at the same site.
