8 Magneitc Stirrers 8.4 | www.hannainst.com heavy-duty HI302N Auto-reverse Magnetic Stirrers HI300N • HI310N Heavy-duty Magnetic Stirrers The HI302N model can stir up to 2.5 liters (0.66 gallons). It is often desirable to stir your samples in two directions. This will achieve maximum homogeneity and solubility. An advanced circuit allows HI302N to reverse the direction of the stirring at a user-selected interval. The interval can be adjusted from 30 seconds up to 3 minutes. In addition to precision speed control, a limiter will also assure that the maximum speed will never be exceeded. Hanna stirrers incorporate a VCO device that stops the motor from accelerating as soon as a load is removed (Speedsafe™). Specifications HI302N Maximum Stirring Capacity 2.5 liters (0.66 gallons) Low Speed Range 100 rpm High Speed Range 800 to 1000 rpm Reverse Interval from 30 seconds to 3 minutes Power Supply 110/115 VAC or 220/240V, 50/60 Hz Installation Category II Cover Material AISI 316 stainless steel Environment 0 to 50°C (32 to 122°F); RH max 95% Dimensions 180 x 180 x 70 mm (7.1 x 7.1 x 2.8”) Weight 1.4 kg (3.1 lb.) Ordering Information HI302N-1 (115V) and HI302N-2 (230V) are supplied with magnetic stir bar and instructions. Accessories HI731320 Magnetic stir bar (10) HI731361 Retriever bar for magnetic stirrers Speedsafe™ Speedsafe™ HI300N and HI310N are heavy-duty stirrers. HI300N can stir up to 2.5 liters (0.66 gallons) of liquid and the HI310N can stir up to 5.0 liters (1.3 gallons). This makes them perfect for laboratory use as well as for use in production. Electronic controls are incorporated into these stirrers that allow the user to regulate the speed with greater precision. With Hanna ’s Speedsafe™, a limiter will assure that the maximum speed will never be exceeded. HI310N also has an automatic feedback feature. The motor is electronically controlled to maintain the chosen speed as the load changes. If the viscosity or the level (¥uid weight) increases or decreases, the circuitry will adjust the output power to keep the speed constant.
