BD Vacutainer™ SST™ II Advance Tubes

Using BD SST™ II Advance, routine analytes in clinical chemistry, such as potassium and glucose, are still stable after a week of storage at 2–8°C. 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 these tubes, which is a distinct advantage during transport and storage.

Advantages of gel tubes versus non-gel tubes:

• Stable barrier between serum and clotted blood, therefore better analyte stability and sample quality
• Optimization 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

Tube usage guidelines:

• Clotting Times: the minimum recommended coagulation time for patients who have not received anti-coagulation treatment is 30 minutes. Tubes contain a clot activator of silica particles.
• Centrifugation Conditions: 1300–2000 g for 10 minutes or alternately 3000 g for 5 minutes, at 18–25°C.
• Effects of Temperature: cooling of the tube during centrifuging can affect the movement capability of the gel. Optimum separation of serum and coagulated blood is achieved at 20–25°C.
• Store at 4–25°C and protected from direct sunlight during storage.
