VWR® Analog hotplate-stirrers
Numerous safety features and user-friendly capabilities make these reliable Standard-Hot Plate Stirrers a valuable addition to any lab. Microprocessor control regulates the heating and spinng function, so samples are heated to temperature quickly and accurately while speed is precisely controlled. The one piece ceramic top plate design features a chemical resistant, reflective white surface that is easy to clean, and the rear housing features a built-in support rod holder with locking knob. Made of a heat resistant polymer, the housing is also resistant to corrosion and offers a spill resistant, low profile design. The unit’s ramping feature slowly increases speed for improved safety and enhanced coupling; this avoids splashing, improves spin bar control, and provides excellent low speed control. Additionally, stir protection automatically shuts down heater if stirrer motor fails and a caution hot top indicator features a warning symbol light that illuminates when the top plate reaches 40°C and remains lit until unit cools down. Units include a 92” detachable, 3-wire cord, and a two year limited warranty on parts and labor. Temperature Range: Ambient, 5°–500°C with ±3% temperature stability.
Speed Range: 60–1600rpm with ±2% speed stability. CSA listed.
