Constructed of an aluminum alloy for optimum thermal conductivitiy, each Reacti-Block contains a thermometer well and has dimensions of 9.4 L × 7.5 W × 5.1 H (cm) for all blocks except F, G, J, and M which have a depth (height) of 7.6 cm.

• Each block contains a thermometer well with size 7.1×36.5 mm (Ø×D mm), except blank blocks J and K.

Reacti-Block™ aluminum blocks are available with many hole configurations, machine-drilled to accommodate almost any size Reacti-Vial™ small reaction vial, test tube or microcentrifuge tube.

Aluminum block models A-1, C-1, Z-1, M-1, S-1, U-1 and V-1 can be used with all Reacti-Therm™ modules, including those equipped with Reacti-Vap™ evaporators. Blocks B-1 and T-1 are specifically designed for use with Reacti-Vap™ units.

Aluminum block models F, G, J, K and L are designed to be used exclusively with the Reacti-Therm™ modules. These are not compatible with Reacti-Vap™ evaporators.
