With a 3ml draw volume, this Glucose Blood Collection Vacuum Tube uses Sodium Fluoride and Potassium Oxalate to stop glucose breakdown. The grey safety cap identifies it for laboratory blood sugar analysis. PET plastic walls maintain vacuum pressure for consistent blood draws despite high humidity.
Key Features
- Sodium Fluoride Additive: NaF and Potassium Oxalate mixture stops glycolysis for 48 hours. Glucose levels remain stable for lab tests.
- Grey Safety Cap: Standardized ISO color-coding for rapid laboratory identification. Prevents selection errors during high-volume testing.
- PET Plastic Construction: Medical-grade material maintains vacuum integrity and resists breakage. Reduces biohazard risk from shattered tubes.
- 3ml Draw Volume: 13x75mm dimensions fit standard laboratory centrifuge rotors. Provides sufficient plasma while minimizing blood draw.
Frequently Asked Questions
What is the use of grey top blood collection tube?
These tubes contain antiglycolytic agents to preserve glucose levels in blood samples. Sodium Fluoride prevents enzymes from breaking down sugar before testing.
Which additive is in glucose vacuum tubes?
The tube contains a mixture of Sodium Fluoride and Potassium Oxalate. These chemicals act as an anticoagulant and stabilizer to stop cell metabolism.
