Thanks for the explanation, David. I could not see that 'parrilla de agitacion' was the same as the agitador itself.

parrilla The 'parrilla' is the hotplate itself. The hotplate can be for multiple pieces of labware and then you have 'multiplate hotplate'.
'Parilla' is actually 'grill', for barbecuing meat and so on, but it is also used in biotech in several Spanish-speaking countries. In Spain you could say 'agitador multiplaca calefactado' or maybe 'agitador multiplaca con placa caliente'.

That was not the question. I know it is a stirring plate. I need to know what the 'parrillas' refer to.
