Product details
The BD Vacutainer® CPT™ Mononuclear Cell Preparation Tube with Sodium Citrate is a specialized blood collection tube engineered to simplify the isolation of peripheral blood mononuclear cells (PBMCs) for clinical and research applications. Manufactured by Becton, Dickinson and Company, this tube combines an anticoagulant with a density gradient medium and polyester gel barrier to deliver consistent and efficient cell separation during centrifugation.
This all-in-one closed system allows blood collection and cell preparation within a single tube, reducing handling steps, minimizing contamination risk, and improving laboratory workflow efficiency. With dimensions of 16 x 125 mm and an 8.0 mL draw volume, it is ideal for higher-volume sampling in immunology studies, flow cytometry, and molecular diagnostics.
Key Features & Benefits:
-
Contains sodium citrate anticoagulant for reliable coagulation control
-
Integrated density gradient and gel barrier for efficient PBMC separation
-
Single-tube collection and processing system saves time and labor
-
Helps reduce contamination and handling variability
-
Suitable for clinical laboratories and research environments
The BD Vacutainer® CPT™ Mononuclear Cell Preparation Tube with Sodium Citrate provides a dependable and streamlined solution for high-quality mononuclear cell isolation and laboratory performance.
BD Vacutainer® CPT™ is a fully-closed system for separation of mononuclear cells from whole blood, where cell separation is carried out in the primary blood collection tube. This decreases the complexity of steps for mononuclear cell separation, thereby minimizing variability from sample processing.
CPT™ is an evacuated, sterile blood collection tube containing buffered sodium citrate or sodium heparin anticoagulant, liquid density medium and an inert gel barrier. It is intended for the collection of whole blood and the subsequent separation of mononuclear blood cells for the purposes of in vitro diagnostic examination.
Whole blood is drawn directly into the CPT™ using standard phlebotomy techniques and processed in the same tube. During centrifugation, the gel forms a physical barrier between the mononuclear cells in plasma and the erythrocytes and granulocytes. The separated, concentrated suspension of mononuclear cells in plasma can then be transported in the primary blood collection tube.
