Description
The OHAUS Guardian™ 5000 Synthesis Kits provide a safe, efficient, versatile, and environmentally friendly solution for heating and stirring standard round-bottom flasks. Designed as a modern alternative to traditional oil baths and heating mantles, these kits eliminate the hazards of oil fires, spills, and toxic fume emissions while avoiding water waste and oil disposal hassles. Each kit includes a Guardian™ 5000 hotplate stirrer, a base block, a stainless steel PT1000 temperature probe, a probe holder kit (stand rod, double clamp, and holding arm), and a flask clamp for complete out-of-the-box operation.
Key Features:
- Enhanced Safety: Base blocks feature two heat-resistant handles for safe positioning and removal when hot.
- Uniform & Precise Heating: Superior to traditional heating mantles, the system offers precise, consistent heat distribution.
- Low-Well Block Design: Prevents glassware cracking or jamming while offering exceptional reaction visibility during experiments.
- Durable Construction: Made from 6082 T651 aluminum alloy with a chemical- and solvent-resistant anodized finish that is durable and easy to clean.
- Modular Cost Savings: High-precision machining makes adding or swapping compact insert blocks effortless, removing the need for multiple full-sized base blocks.
- Complete Ready-to-Use Packages: Each kit comes complete with a stand rod, double clamps, a probe holding arm, a PT1000 stainless steel temperature probe, and a flask clamp for immediate setup.
