Diluting POLYOX WSR-301 (Polyethylene Glycol) to a 3% liquid solution involves accurately measuring the amount of the polymer and the solvent (usually water) to achieve the desired concentration. Here's a general procedure to create a 3% solution:

Materials needed:

- POLYOX WSR-301 PEG 90M

- Distilled water (or appropriate solvent)

Steps:

1. **Calculate the amount needed:** The concentration of the final solution is 3%. If you want to prepare a specific quantity (let's say 100 grams), you'll need to calculate the amount of POLYOX WSR-301 and water required.

2. **Determine the amount of POLYOX WSR-301:** For a 3% solution of a total volume of 100 grams, you'd need 3 grams of POLYOX WSR-301 (3% of 100 grams).

3. **Measure the water:** Subtract the weight of POLYOX WSR-301 (3 grams) from the total weight (100 grams), which leaves you with 97 grams of water needed (100 grams total - 3 grams of the polymer).

4. **Weigh the POLYOX WSR-301:** Using a precise scale, measure out 3 grams of POLYOX WSR-301.

5. **Mix with water:** Add the 3 grams of POLYOX WSR-301 to 97 grams of distilled water in a suitable container. Stir thoroughly until the polymer dissolves completely. Make sure the mixing is uniform to achieve a homogeneous solution.

6. **Test the solution:** After mixing, allow the solution to rest and ensure it remains homogeneous. If needed, you can adjust the quantities accordingly for larger or smaller volumes.

Note: Always ensure the equipment used is clean and dry to prevent contamination and accurately measure the amounts to maintain the desired concentration.

Also, keep in mind that this procedure is a general guideline. Always refer to the specific instructions provided by the manufacturer for precise measurements and mixing instructions.
