MULTIPURPOSE ALUMINUM HEAT/REACTION BLOCK
This reaction heat block fits 4 types of glassware common to all chemistry labs: the block can hold 1 x 25 mL RBF, 7 x 20 mL scintillation (28 mm) vials, 9 x 2-dram vials, and 3 NMR tubes! Say goodbye to oil baths!
The heat block fits all 135 mm hot plate stirrers and even has two slots for a digital temperature probe (including the PT-100 temperature sensor). In addition to heating reaction samples, this block can easily be chilled in a refrigerator/freezer to act as a cooling block.
