Medical Cotton Rolls

Introduction to Medical Cotton Rolls

Medical cotton rolls are essential components in various medical and laboratory settings. These specialized tools are integral in the collection and preservation of blood samples, ensuring that they remain stable for analysis and use. With a range of types available, each designed for specific applications, medical cotton rolls are indispensable for professionals in the healthcare industry.

Types and Identification

The diversity of medical cotton rolls is evident in their design and function. Each type is distinguished by a color-coded cap, which signifies its purpose and the additive it contains. For instance, tubes with light blue caps are infused with 3.2% sodium citrate for coagulation tests. Red or gold-capped tubes contain clot activators, making them suitable for serology and immunology tests. The variety ensures that professionals can select the appropriate tube for their specific needs.

Applications and Features

The application of medical cotton rolls spans across numerous fields, from clinical laboratories to blood banks. Their role is critical in the accurate testing of glucose levels, lactic acid, blood alcohol content, and more. The presence of additives like sodium fluoride, oxalate ions, potassium EDTA, and heparin compounds in these tubes enhances their functionality, catering to routine chemistry tests and hematology examinations.

Materials and Advantages

Constructed from durable materials such as plastic or glass, medical cotton rolls are designed to maintain a vacuum, facilitated by a rubber stopper. This vacuum is crucial for the preservation of the blood sample's integrity. The choice of material also plays a role in the tube's suitability for various tests, ensuring that the samples are not contaminated and that the results are reliable.

Selection Criteria

Choosing the right type of medical cotton roll is a process guided by the intended use and the specific additives required. Professionals can select from an array of options to find the tube that aligns with their testing requirements. It is important to consider the compatibility of the tube with the sample and the test to ensure accurate results.

Purchasing Considerations

When sourcing medical cotton rolls, it is vital to consider the preservation capabilities and the specific uses of each type. While Alibaba.com offers a platform to connect with a variety of suppliers, the selection should be made based on the functionality and application of the tubes without compromising on the integrity of the samples they are meant to secure.
