Ohaus GUARDIAN™ 5000 Hotplate Stirrer With Synthesis Kit for 1000mL Flask Capacity
Item#: 31076461The 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.

- As a safer alternative to oil bath, the synthesis kits eliminate the risks of oil fires, spills, and toxic fume emissions. The base blocks include 2 heat-resistant handles
for safe handling when hot. - Compared to traditional heating mantles, the synthesis kits provide precise, uniform heating. Their 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 base blocks. Thanks to high-precision machining, inserting and removing them is as easy as building blocks.
- Benefit from a chemical and solvent-resistant anodized finish, the blocks are durable and easy to clean. No water waste since water baths are not used. Also, there is no need to dispose of used oil.
