L-K Industries designed the Benchmark C as the first state-of-the-art oil centrifuge with Class I, Division 2 certification. It is ideal for laboratory settings or refineries using 100-mL capacity tube configurations. It is usually installed on benchtops for testing crude oil or refined petroleum products. The fully insulated centrifuge prevents heat loss and allows for more accurate temperature control. Its sturdy outer case is finished with a solvent-resistant powder coating. With a motor capable of operating at 2300 rpm and real-time temperature readings, this unit has unmatched precision in basic sediment and water (BS&W) determination. The digital programmable temperature controller (ambient inner bowl temperature up to 200°F/93°C) provides better process control for testing heavy crude oil. The integrated countdown timer, which shuts down the motor when a test is complete, reduces variation in testing. The internal programmable, solid-state motor controller enables linear acceleration, which results in more consistent testing. Specially designed collars, cushions and shields help reduce glass tube breakage at higher G-forces. The Benchmark C features a latching emergency stop button and automatic locking lid (motor will not operate when lid is open; lid will not open while motor is running). It comes with a standard 4-place trunnion arm configuration (compatible with B, C, D or E style tubes) and is available in 120VAC or 240VAC. Because of its Class I, Division 2 certification, the unit requires hard-wiring.
