OHAUS Guardian 5000 Synthesis Kits
The OHAUS Guardian™ 5000 Synthesis Kits are designed for safe, clean heating with standard round-bottom flasks, making 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 250mL, 500mL, or 1000mL flasks. Additionally, optional insert blocks accommodate smaller flasks down to 25mL (sold separately).
Key Features
- As a safer alternative to oil bath, the synthesis kits eliminate the risks of oil fires, spills, and toxic fume emissions
- Base blocks include 2 heat-resistant handles for safe handling when hot
- Compared to traditional heating mantles, the synthesis kits provide precise, uniform heating
- Low-well design prevents glassware cracking or jamming and ensures excellent reaction visibility
- As flask sizes vary, the compact insert blocks help users save costs by avoiding multiple block bases
- Thanks to high-precision machining, inserting and removing blocks is as easy as building blocks
- Blocks are durable and easy-to-clean with a chemical and solvent-resistant anodized finish
- Rod stand, probe & holder, and flask clamps are all included in package for immediate installation
- Capability to install a second rod and additional clamps for more sophisticated apparatus setup
