Blood procoagulant powder is a type of blood collection additive, in other words, it is in the form of a powder of a procoagulant that has not been dissolved or diluted. After adding certain substances, the procoagulant powder can be used as a procoagulant in blood collection vessels. It is mainly used to accelerate blood procoagulant in blood collection vessels, facilitating the separation of serum and serum for in vitro diagnosis. Can be made into serum type vacuum blood collection vessels such as procoagulant tubes, separation gel procoagulant tubes, etc. Perhaps everyone usually comes into contact with pre prepared blood coagulation promoting powder solvents, and rarely sees them in powder form, nor do they know what the preparation method is. Below is a brief description of the solvent preparation method for promoting coagulation powder. To prepare 1L of coagulation promoting powder solution, we need to prepare the following reagents: 1. 60 grams of coagulation promoting powder powder; 2. 850 milliliters of alcohol; 3. 18 grams of water-soluble silicone oil; 4. 150 milliliters of distilled water; 5. 18g polyethylene glycol 400. Required equipment: 1. Electronic balance; 2. Two measuring cylinders with a measuring range of 100ml; 3. Two clean beakers; 4. Glass stirring rod. Configuration steps: 1. Pour 850ml of prepared alcohol into half to 60g of coagulant powder powder, stir with a glass rod until completely dissolved (as there will be some precipitation after the coagulant powder dissolves, this step involves adding alcohol in two steps to avoid residual coagulant powder in subsequent containers), and obtain reagent A for later use; 2. Add the weighed water-soluble silicone oil and polyethylene glycol 400 medium to distilled water, stir to fully blend, and obtain reagent B; 3. Mix the prepared reagents A and B into a beaker, stir well, and clean the beaker containing the accelerator solvent with the remaining ethanol from step 1 to avoid loss of the bottom of the powder precipitation cup. Then, pour the alcohol into the mixed AB reagent; 4. Continue stirring with a stirring rod for 30 minutes to thoroughly mix and obtain 1L of successfully prepared blood coagulation promoting powder solvent.
