Description générale
Typical molecular weight cut-off = 14,000.
Conditionnement
Supplied in rolls, dry
Qualité
May contain glycerin and sulfur compounds in more than trace amounts.
Notes préparatoires
Removal of glycerol included as a humectant can be accomplished by washing the tubing in running water for 3-4 hours. Removal of sulfur compounds can be accomplished by treating the tubing with a 0.3% (w/v) solution of sodium sulfide at 80°C for 1 minute. Wash with hot water (60°C) for 2 minutes, followed by acidification with a 0.2% (v/v) solution of sulfuric acid, then rinse with hot water to remove the acid. This tubing will retain most proteins of molecular weight 12,000 or greater.

In the present study, novel block copolymers of poly(l-lactide)-block-poly(propylene adipate) (PLLA-b-PPAd) were synthesized in two ratios, 90/10 and 75/25 w/w and were further investigated as long-acting injectable (LAI) polymeric matrices in naltrexone base microparticle formulations. The synthesized polymers were characterized

Dialysis Tubing

Does this dialysis tubing (D9402-100FT) support low pH solutions (<2)? My sample contains polymer dissolved in methanesulfonic acid, making it a very low pH sample. The gaol of the dialysis is to remove most of the acid before neutralization.
