Ohaus GUARDIAN™ 5000 Hotplate Stirrer With Synthesis Kit for 250mL Flask Capacity

Item#: 31076459

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.

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.
