The new Guardian 5000™ synthesis kits are designed for safe, clean heating with standard round-bottom flasks. Our goal is to make it easier for chemists to assemble, replace, and maintain experimental setups. The range includes 3 basic kits, each featuring a Guardian 5000™ hotplate stirrer and a base block compatible with 250 mL, 500 mL, or 1000 mL flasks. Additionally, 18 insert blocks accommodate smaller flasks down to 25 mL.
