Where do you all buy your external columns heaters?

I have a GPC method that requires 5 7.8x300mm columns along with a guard column. These are all going to be assembled with a column selector valve that will be working in cohorts with another set of columns. I'm trying to find an external column heater that can contain all of these columns and transition between column sets with ease. My company is based in America. Where would I be able to find a column heater to accommodate all of these details?

    Hi,

    The guard columns will not fit in the heater with any column longer than 25 cm.  The units will hold 4 of the below columns.  

    Column heater insert kits (old column design)

    4 mm x 15 cm columns (WAT038121)

    4 mm x 25 cm columns (WAT038122)

    4 mm 30 cm columns (WAT038123)

    8 mm x 25 cm columns(WAT038124)

    8 mm x 30 cm columns (WAT038125)

    8 mm X 30 cm columns (WAT038126)


    Column heater insert kits (new column design)

    4 mm x 15 cm columns (WAT019886)

    4 mm x 25 cm columns (WAT019887)

    Hope that helps!

    HI cgurahoo, 
    The 2414 and the TCM - can control a larger external heater CHM up to 150 degrees and I believe it can handle the larger columns.

    Would it be able to hold 4 columns and a guard column (sorry, I should've specified on here)
