Kit includes convenient work tray, stain resistant labels, and one 250 mL bottle of each of the following: Gram Crystal Violet Solution, Gram Iodine Diluent with Iodine Concentrate, Gram Decolorizer Solution, and Gram Safranin Solution.

Four-Step Gram Stain Kit with Isopropyl Decolorizer contains the same ingredients as 1308, but includes an isopropyl decolorizer instead of the Gram Decolorizer.

Bulk Reagents come in space-saving one-gallon containers. Feature a “Keep Clean Tap” for easy control and mess-free dispensing.
