Round based or flat based tubes & Tapval-sealing

The Tapval® system is unique! This system has a cross cut closure. This gives an easy access to the tube with a tip or pipette without having to open it. After exiting the tube, the rubber cap closes due to the 4 membranes which are folded after the extraction. The tube is again hermetically closed and 100% leak-proof.

Packaging: tray of 500 pieces.
Assembled, not sterile.
Irradiated available on request.
