Trundle Wheel Capacity_200mL Iodine clock reaction kit demonstrates

Iodine clock reaction kit demonstrates reaction kinetics through dramatic color changes

Used as a negative stain to highlight bacterial morphology and capsules without fixing cells first

the disaccharide used as a simple-sugar source in fermentation and as substrate for invertase enzyme kinetics

displayed on a plastic-and-metal rack with a carrying handle for transport

and month on a multi-function readout for lab and classroom timing
