No. I dont have one. You may test it with buffer solution to get a sense how fast it works.
I believe you can also use high MW polyacrylic acid powder as well.
OK, call me a great big chicken, but seeing anything with "acrylic acid" and "powder" in the same sentence worries me a lot more than anything with PEG.
Also, the Pierce website talks of simply air-drying the dialysis tubing after the dialysis stage. Slower than PEG, but maybe less risk of overdrying.
No problem. Thats the absorbent polymers used in baby diapers.
