Why is PET Blood Collection Tube vendor Better?
What Are the Advantages of PET Blood Collection Tube?
Polyethylene terephthalate (PET) blood collection tubes have revolutionized the field of phlebotomy and blood collection due to their numerous advantages over traditional tube materials. These tubes, made from PET plastic, offer a range of benefits that enhance sample integrity, accuracy, and safety in the blood collection process.
With competitive price and timely delivery, Xiangyi sincerely hope to be your supplier and partner.
1. Biocompatibility and Material Purity
PET is known for its exceptional biocompatibility and inertness. Blood collection tubes made from PET ensure minimal interaction between the tube material and blood components. This reduces the risk of contamination or interference with blood samples, preserving the integrity of collected specimens for accurate analysis.
2. Clarity and Transparency
PET tubes exhibit high clarity and transparency, allowing for easy visual inspection of blood samples. This transparency ensures that phlebotomists and laboratory technicians can visually assess the quality of the collected sample, confirming its suitability for analysis without compromising sample integrity.
3. Chemical Resistance
PET blood collection tubes possess excellent chemical resistance, minimizing the risk of chemical leaching or contamination. This resistance ensures that the tubes maintain their structural integrity even when exposed to various additives or anticoagulants used during blood collection, preventing any alteration of sample properties.
4. Reduced Risk of Additive Interference
PET tubes have a lower tendency to interact with common blood collection additives such as anticoagulants or clot activators. This reduced interaction ensures that the additives maintain their efficacy, leading to more accurate and reliable test results without interference from the tube material.
5. Improved Sample Stability
PET tubes contribute to enhanced sample stability over time. They minimize the potential for sample degradation, clotting, or hemolysis, ensuring that the collected blood remains viable for a longer duration. This stability is crucial for various diagnostic tests requiring accurate and stable blood samples.
6. Compatibility with Modern Laboratory Techniques

8. Environmental Considerations
PET tubes are recyclable, contributing to environmentally friendly practices in healthcare settings. Their recyclability reduces waste generation and promotes sustainability, aligning with eco-conscious initiatives within healthcare facilities.
9. Enhanced Patient Comfort
PET tubes are lightweight and ergonomic, enhancing patient comfort during blood collection procedures. Their design minimizes the risk of breakage, ensuring a safe and comfortable experience for patients while facilitating ease of handling for phlebotomists.
Conclusion
The advantages of PET blood collection tubes encompass a spectrum of benefits ranging from sample integrity and accuracy to workflow efficiency and environmental considerations. Their biocompatibility, transparency, chemical resistance, and compatibility with automation systems make them invaluable tools in modern phlebotomy, significantly improving the quality and reliability of blood samples for diagnostic purposes.
The adoption of PET blood collection tubes reflects a commitment to maintaining sample integrity, ensuring accurate test results, and prioritizing both patient and laboratory staff safety in the blood collection process.

Modification of PET Blood Collection Tubes - Stanford University
Dr. Richard Zare and colleagues have developed an inexpensive, fast and simple method for treating polyethylene terephthalate (PET) blood collection tubes (BCTs) to remove bias and interference in various blood analysis procedures. Blood collection and processing are two major steps in pre-analytical laboratory testing. Traditionally, glass was the preferred material for making BCTs. However, due to danger from broken glass, BCTs are now made of plastic, specifically PET. The PET polymer surface is hydrophobic and not optimal for blood analysis as cells and analytes are adsorbed on the plastic surface. To overcome this limitation, tube manufacturers add a surfactant coating to the tube to make the inner surface hydrophilic. This approach has its own problems as the surfactant additives can interfere with blood analysis. Attempts have been made to minimize this interference but the methods are expensive, time consuming and/or ineffective. To overcome these problems, the inventors have developed an efficient and inexpensive method to prepare glass-like PET surfaces inside BCTs.
Stage of Research
The inventors have compared BCTs modified with their method, commercially available BCTs and glass BCTs in a number of clinical chemistry analyses using quality control material and patient blood samples. The results show that the inventors' modified BCTs exhibit bias-free performance, i.e. they behave like the gold standard glass tubes.
