Made of a clear polypropylene, supplied capped and labeled with an inert polyethylene cap.
To permit a fast serum separation of the blood clot, the tubes have an inert additive inside which speeds up the coagulation. This accelerator allows a mixture with the blood almost immediate and avoids the unnecessary sample dilution.
The coagulation speed is much higher than the obtained with the glass tubes or the other existing tubes on the market.
The inert granules are rounded to avoid erythrocytes lesions during centrifugation and minimize the risk of haemolysis. These granules are located between the clot and the separated serum working as a retaining wall. It assures a comfortable pipette action or serum decanting. (It isn’t a watertight barrier). Inside the tube there is also a little amount of a glucose preservative, lithium iodoacetat, which maintains the sample stable up to 6 days and allows to make most of the biochemical measurements with an only tube (the exceptions are CPK and Lithium); so it’s possible to save one of the two tubes used
normally to determine routine tests and glucose respectively.
With the ergonomic features of the cap the design achieves a high reliability without avoiding the main characteristic of the cap: it’s very easy to use.
On the label of each tube the lot number, expiry date and volume are printed.
Presentation: packed in black bags in order to maintain them out of the light because the iodum is photosensitive.
Keep these tubes at a room temperature.
Supplied in plastic racks.
