Ideal for capping and recapping 15 – 16mm blood collection tubes, Deltalab’s Green Polyethylene Caps for 15 – 16mm Tubes with Internal Chamber are designed to be placed and removed securely. Each cap has an internal chamber for more liquid filling, thus compensating for the loss of space inside the tube caused by the insertion of a cap. They are also ergonomic and have a ribbed surface. Their shape is slightly conical for better handling.
These leakproof caps also feature an external flap to avoid contact between liquid and fingers when opening the tube, preventing dripping when the cap is left on the bench top, and provide easy single-handed opening.
