Analytical’s Gen I Micro (silver) Photoredox Reaction Blocks (96970, 24250) can accommodate both 4x21mm (50µl) glass vial inserts as well as 5x31mm (250µL) inserts. By default, Micro Reaction Blocks ship with 1” screws tailored for 4x21mm insert use. When using 5x31mm inserts, longer screws will need to be ordered.

Please note that our new 96-Position Micro Block for crystallization and microscopy (961970) is the opposite. The block ships with screws for use with 5x31mm inserts by default. When using with 4x21mm inserts, shorter screws will need to be ordered.

Please contact Analytical for more information.
