    Need new jar of R-870 powder - Different versions available

    I need to replace my jar of R-870 powder. I see other versions available. 870-I, 870-J. Does anyone know if there is a difference? Can I use any of these for the FAS/DPD test with rejents R-0003 and R-871?

    Thanks.

    The letter at the end just indicates the size of the reagent. Either would work with R-0871 and R-0003. In particular:
    R-0870-I 10 g of powder
    R-0870-J .25 lb of powder

    For reference, the TFT kit includes the 10g size. .25lb is roughly 113 grams or ~11 times that amount.

    Reagent Size Code Explanation
    A = .75 oz (22 mL), A-24 = .75 oz (24 pack), A144 = .75 oz (144 pack), B = 2 oz (60 mL, wide-mouth),
    C = 2 oz (60 mL), C-12 = 2 oz (12 pack), D = 4 oz, DD = 8 oz, DB = dropper bottle, E = 16 oz, F = 32 oz,
    F4 = 32 oz (4 pack), G = gal, G4 = gal (4 pack), H = 25 g, I = 10 g, II = 50 g, J = .25 lb, K = 1 lb,
    Z = 1,000 pack, Z-10 = 10,000 pack, Z-50 = 50,000 pack
