As mentioned earlier, grey rubber stoppers are primarily used for sodium fluoride and potassium oxalate blood collection tubes. These additives play a critical role in specific blood tests, particularly those involving glucose measurements. Sodium fluoride is an anticoagulant that inhibits glycolysis, the process through which glucose is broken down in the blood sample. Potassium oxalate, on the other hand, helps prevent clotting by binding calcium in the blood.

The grey rubber stopper is designed to accommodate these additives while keeping them securely contained, ensuring the proper chemical reaction occurs in the sample. This is crucial for the accurate measurement of glucose levels, which is vital for the diagnosis of diabetes and other metabolic conditions.

The grey rubber stopper offers a variety of benefits that make it a preferred choice in blood collection systems. Some of the key advantages include:

Grey rubber stoppers are made from high-quality rubber materials that offer superior durability. They can withstand the rigors of transportation and handling without deteriorating, cracking, or losing their sealing capabilities. This ensures that the blood samples remain securely sealed from the moment they are collected to the point they are processed in the laboratory.

The stoppers are also chemical-resistant, meaning they will not degrade when exposed to the chemicals inside the blood collection tubes, such as sodium fluoride or potassium oxalate. This makes them highly reliable for maintaining the stability of the sample for extended periods, reducing the risk of sample degradation or inaccurate test results.

Grey rubber stoppers are easy to install and secure in blood collection tubes, making the process of collecting blood samples more efficient. Their uniform design allows for a snug fit in various sizes and types of blood collection tubes, ensuring a consistent and reliable seal. The design of the stopper ensures that it is easy to remove when the sample is ready for processing without causing contamination or damage to the tube.

Grey rubber stoppers are compatible with a wide range of blood collection tube types used in different diagnostic tests. They are typically used in tubes that are designed for glucose testing, but can also be used in tubes that require anticoagulants or preservatives. Their versatility allows medical professionals and laboratory technicians to streamline their blood collection and storage processes while ensuring that samples are prepared correctly for a variety of tests.
