Sodium Fluoride 2ml Vacuum Blood Collection Tube Double Cap (Pack of 100)

Sodium Fluoride 2ml Double Cap Vacuum Tubes are designed for the collection, storage, and transport of blood samples specifically for glucose testing and other biochemical assays that require the inhibition of glycolysis. They are commonly used in clinical settings, such as hospitals, diagnostic labs, and research institutions, where precise glucose measurements are essential for patient diagnosis and monitoring.

Key Components:

• Sodium Fluoride (NaF):
  • Glycolysis Inhibitor: Sodium fluoride is a chemical additive used to prevent the enzymatic breakdown of glucose in the blood. This is crucial because glycolysis can lead to falsely low glucose levels if not inhibited promptly after blood collection.
  • Preservation of Glucose: By inhibiting glycolysis, sodium fluoride ensures that the glucose levels in the blood sample remain stable from the time of collection until the sample is processed in the lab, allowing for accurate blood glucose analysis.
• Potassium Oxalate:
  • Anticoagulant: Often used in conjunction with sodium fluoride, potassium oxalate prevents blood from clotting, ensuring a clear sample for analysis.

Tube Design:

• 2ml Volume Capacity:
  • Compact and Efficient: The 2ml volume is ideal for situations where only a small amount of blood is needed, minimizing the burden on the patient while providing sufficient material for testing.
• Double Cap System:
  • Primary Cap: The inner cap ensures a tight seal that maintains the vacuum inside the tube, preventing air from entering and blood from leaking out.
  • Secondary Cap: The outer cap provides an additional layer of security, protecting the inner seal from accidental opening or contamination during handling and transport.
  • Color-Coded: Typically, these tubes have a grey cap, which is standardized for tubes containing sodium fluoride and potassium oxalate. This color-coding helps laboratory technicians quickly identify the type of additive and the intended use of the tube.

Usage:

• Blood Collection: The tubes are used with standard venipuncture equipment. Once blood is drawn into the tube, the sodium fluoride immediately starts inhibiting glycolysis.
• Handling and Transport: The double cap ensures that the sample is protected during transport to the laboratory, reducing the risk of contamination, leakage, or degradation of the sample.

Advantages:

• Accuracy: By preserving glucose levels, these tubes provide more reliable results in glucose testing, which is crucial for managing conditions like diabetes.
• Safety: The double cap system reduces the risk of accidental exposure to the sample, protecting healthcare workers and maintaining sample integrity.
• Convenience: The compact 2ml size is easier to handle and store, making it ideal for use in various healthcare settings.

Standards and Compliance:

• Regulatory Compliance: These tubes typically comply with international standards for medical devices and laboratory equipment, ensuring their safety, reliability, and effectiveness in clinical use.

Sodium Fluoride 2ml Double Cap Vacuum Tubes are a critical tool in the accurate measurement of blood glucose levels, providing both healthcare providers and patients with the reliable data needed for effective diagnosis and treatment.
