[Package Specification] Plastic bottle, 500g/bottle

[Performance] White crystal powder, odorless, soluble in water, easy to absorb moisture, Stable at room temperature. The main content of tri-potassium EDTA ≥99.0%. See the product test report for other indicators.

1. Adding with machine:

(1) Cleaning: Before using the machine, it is necessary to carefully clean the containers and delivery pipes on the machine, rinse with deionized water, then clean the containers and pipes with 80% alcohol for 3 times, then clean the containers and pipes with more than 99% ethanol, and dry the alcohol with hot air. Ensure that no impurities, water adhere to the tube and wall, avoid contamination or dilution of tripotassium EDTA.

(2)Adjusting machine: Determine the amount or volume of tripotassium EDTA to be added according to the planned volume of blood tubes, adjust the flow regulator of the machine to the appropriate value, add 10-100 tubes, and check whether the added dose meets the requirements. The admissible error of solution addition is ±10%. 

2. Add manually:

(1) Clean containers and tools: Cleaning containers and pipettes for repacking tripotassium EDTA solution with the same method as that of the machine.

(2) Distribute tripotassium solutions and tools: divide the tripotassium solutions into cleaned containers and distribute them to the operators together with the cleaned and adjusted pipettes. Note that the scale of the pipette should be adjusted to ensure that the volume of added solution meets the specified requirements.

(3) Adding solution: use a pipette to add the tripotassium solution into the blood collection tube. Confirm the quantity of each operator. In the process, random inspection shall be conducted at any time. The allowable error range of adding amount is ± 10%.
