The vacuum blood collection tube for separating plasma includes an inner tube and an outer tube, the outer tube is sleeved outside the inner tube and is characterized in that a tube cover for fixing the relative position between the inner tube and the outer tube is arranged on the nozzle of the vacuum blood collection tube, the tube cover is provided with an inner rubber plug to cover the inner nozzle of the inner tube and an outer rubber plug to cover the annular nozzle between the inner tube and the outer tube, leaving a space between the outer tube and the inner tube is a filter mesh tube for filtering out plasma, the diameter of the filter mesh tube is less than or equal to 1 μm, and the inner wall surface of the inner tube is provided with an anticoagulant coating for preventing the blood flowing into the inner tube from coagulating during blood collection. The inner tube adopts a filter mesh tube, which provides multiple filtration channels for plasma filtration, which effectively prevents the blocking of the filter holes and prevents the plasma from being separated and collected; the plasma can be quickly filtered out through the filter holes and flow into the outer tube, and other formed components in the blood cannot By being retained in the inner tube, it can be carried away with the inner tube, ensuring the collection of plasma.
Testing Areas: Gongdong Medical's plasma blood collection tubes can be used for coagulation
function test, clinical chemistry for emergency treatment, blood rheology test, glucose and
lactate test molecular and biology test (such as PCR).
Additives: According to different additives, our plasma blood collection tubes can be divided into five different types (3.2%Sodium Citrate Buffer(0.109mol/L), Sodium Heparin/ Lithium Heparin, Gel & Sodium Heparin/ Gel & Lithium Heparin, Sodium Fluoride & Sodium Heparin/ Sodium Fluoride & EDTA/ Sodium Fluoride & Potassium Oxalate, and Gel & Sprayed K2·EDTA/ Gel & Sprayed K3·EDTA). They are coagulation tube, heparin tube, gel & heparin tube, glucose tube, EDTA & Gel tube.
Tube Materials: The main used materials are PS， PP， PET， PC， PETG， Glass， HDPE， LDPE， POM， PA， ABS， PMMA, etc.
Tube Sizes (mm): 13*75 , 13*100 , 16*100, 10.25*64

Adding heparin lithium anticoagulant to the inert separation rubber tube can achieve the purpose of rapid separation of plasma. Potassium oxalate/sodium fluoride, sodium fluoride is a weak anticoagulant, generally used in combination with potassium oxalate or sodium ethiodate, the ratio is 1 part of sodium fluoride and 3 parts of potassium oxalate. It is an excellent preservative for blood glucose measurement, and cannot be used for the determination of urea by the urease method, nor for the determination of alkaline phosphatase and amylase. It is recommended for blood glucose detection. In the sodium citrate anticoagulation tube, sodium citrate mainly plays an anticoagulant effect by chelating with calcium ions in the blood sample and is suitable for coagulation tests.
