SST Tubes

BD Vacutainer® SSTTM II Advance Tubes.

During the centrifugation of the BD Vacutainer® SSTTM II Advance Tubes, an inert gel separates the serum and the
blood clot preventing the contamination of the serum from the separated cellular components. For example, the serum for certain analytes such as potassium, phosphorus and glucose must be separated from the cells within a few hours – otherwise the results will be significantly distorted.

Using BD SSTTM II Advance Tubes routine analytes in clinical chemistry such as potassium and glucose are still stable after a week of storage at 2-8ºC. Clinical evaluation of special chemistries such as therapeutic drugs, proteins, peptides, steroids and vitamins demonstrates a high degree of stability with the acrylic gel in the BD SSTTM II Advance Tubes1,2,3. As a result of the type of gel used in the BD Vacutainer® SSTTM II Advance Tubes, short centrifugation times of 5 minutes at 3000 g can be achieved. The stability of the gel barrier is a distinct advantage during transport and storage.

The main advantages of gel tubes versus non-gel tubes are:
• Stable barrier between serum and clotted blood, therefore better analyte stability.
• Better sample quality.
• Optimisation of the work flow: Short centrifugation time, sample processing and archiving in the primary tube.
• No possibility of misidentification due to the use of secondary tubes.
