I claim the ornamental design for a reaction block for chemical synthesis for use upon a hot plate stirrer, as shown and described.

FIG. 1 is a top perspective view of a reaction block for chemical synthesis for use upon a hot plate stirrer showing my new design;

FIG. 2 is a top plan view thereof;

FIG. 3 is a bottom plan view thereof;

FIG. 4 is a front side elevation view thereof;

FIG. 5 is a rear side elevation thereof;

FIG. 6 is a left side elevation view thereof; and,

FIG. 7 is a right side elevation view thereof.

The broken lines in the drawings, FIGS. 1–3, are for illustrative purposes only and form no part of the claimed design.

The characteristic feature of the design resides in a round reaction block for accepting round bottom flasks and adapters.

Ware, Steve
