Following a a single-hour incubation period of time, the tubes are flipped 180°. A business clot that stays in the bottom in the tube implies a constructive response. When the liquid flows down the aspect from the tube, the result is damaging for endotoxins.
Where the Assay inside of a monograph offers a technique for that Assay preparation, where the total withdrawable contents are to be withdrawn from only one-dose container with a hypodermic needle and syringe, the contents are to generally be withdrawn as wholly as feasible right into a dry hypodermic syringe of the rated capability not exceeding three times the quantity to generally be withdrawn and fitted having a 21-gauge needle not fewer than two.
