Frequently asked questions
Does this tube provide efficient serum separation?
Yes, it is designed for advanced serum separation. It features an integrated clot activator and a separator gel that creates a stable barrier between the serum and cellular components after centrifugation, ensuring a clean yield for your diagnostic testing.
Is the material durable for laboratory use?
Absolutely. These tubes are manufactured from high-quality Polyethylene Terephthalate (PET). This material is chosen for its:
- Shatter-resistance: Providing structural integrity during handling and processing.
- Clarity: Offering excellent visibility of the sample inside.
Are these tubes manufactured domestically?
Yes, these tubes are proudly made in the United States. They are fully compliant with both Trade Agreement Act (TAA) and Buy American Act (BAA) standards, ensuring high production quality and regulatory compliance.
What is the function of the internal coating?
The interior of the tube features a silica coating. This acts as a highly effective clot activator, which works in conjunction with the separator gel to accelerate the coagulation process and yield high-quality serum samples.
How do I identify this specific additive type?
The tube features a color-coded closure system designed for fast-paced laboratory environments. The cap is red with a distinct yellow ring, allowing for quick, accurate identification of the clot activator and separator gel additive.
Is the pull cap easy to handle?
The pull-cap mechanism is engineered for ease of use. It is designed to provide a secure seal for sample integrity while remaining simple to operate in busy hospital phlebotomy departments and clinical labs.
What is the standard capacity of these tubes?
Each tube is designed to hold a volume of 8 mL. The dimensions of the tubes are 16 x 100 mm, making them compatible with standard centrifugal equipment found in most medical and research facilities.
Are these tubes provided sterile?
Yes, all tubes are supplied sterile. They are designed for clinical environments where maintaining sample purity and preventing contamination is of the utmost importance.
How are these units packaged for order?
These collection tubes are sold in a case configuration of 50 tubes per box. This ensures you have a consistent supply ready for your clinical or research needs.
Are these suitable for standard centrifugation?
Yes, these tubes are specifically designed to be utilized in conjunction with standard centrifugal equipment. The separator gel ensures a clean separation of serum during the spinning process, creating a stable, reliable barrier.
