VELP MULTISTIRRERS Multi-Position Magnetic Stirrers (6 & 15 Position) The VELP MULTISTIRRER series are multi-position magnetic stirrers engineered for the simultaneous mixing of multiple samples in chemistry, microbiology, and biochemistry applications. Available in four variants across two dimensions and two control interfaces, the series accommodates either 6 positions of 400 ml or 15 positions of 250 ml, making it easy to scale throughput to the demands of any lab workflow. Built on an epoxy-painted metal structure with a stainless steel top plate, every model in the series stays cool even after days of continuous unattended use. Powered by a high-power PCM magnet stirring system and SpeedServo™ technology, all variants deliver consistent, reliable speed control from low revolutions up to 1500 rpm. Designed and manufactured in Italy, the MULTISTIRRER series is a robust and dependable platform for any multi-sample lab environment. Features All Models Multi-position stainless steel top plate on an epoxy-painted metal structure, stays cool even after days of continuous use SpeedServo™ technology maintains constant stirring speed and compensates automatically for viscosity changes High-power PCM magnet stirring system operated by a mono-phase motor for continuous operation Speed regulation from 80 to 1500 rpm with excellent low-speed control Available in 6-position (400 ml) and 15-position (250 ml) configurations to match lab throughput needs Universal voltage input (100-240 V) for use anywhere in the world Ideal for chemistry, microbiology, and biochemistry applications Digital Models Only Bright digital display for accurate speed monitoring, adjustable in 10 rpm steps Built-in programmable timer (1-900 minutes, plus continuous mode) for unattended operations Auto-reverse function (5-900 seconds) to improve mixing efficiency in viscous samples Intermittent mode for pulsed stirring to match any workflow requirement Safety lock function prevents accidental changes to working conditions during a run 15-Position Models 15 simultaneous stirring positions for 250 ml beakers, ideal for high-throughput screening and parallel processing 74 mm centre-to-centre spacing between stirring positions 6-Position Models 6 simultaneous stirring positions for 400 ml beakers, suited for larger individual sample volumes 100 mm centre-to-centre spacing between stirring positions Specifications MULTISTIRRER 6 MULTISTIRRER 15 MULTISTIRRER Digital 6 MULTISTIRRER Digital 15 User Interface Analog Analog Digital Digital Positions 6 15 6 15 Stirring Volume 6 x 400 ml 15 x 250 ml 6 x 400 ml 15 x 250 ml Centre Spacing 100 mm 74 mm 100 mm 74 mm Speed Range 80-1,500 rpm 80-1,500 rpm 80-1,500 rpm 80-1,500 rpm Speed Interval — — 10 rpm steps 10 rpm steps Torque Compensation SpeedServo™ SpeedServo™ SpeedServo™ SpeedServo™ Stirring System PCM magnet PCM magnet PCM magnet PCM magnet Timer No No 1-900 min / continuous 1-900 min / continuous Auto-Reverse No No 5-900 seconds 5-900 seconds Lock Function No No Yes Yes Intermittent Mode No No Yes Yes Construction Epoxy metal / stainless steel top Epoxy metal / stainless steel top Epoxy metal / stainless steel top Epoxy metal / stainless steel top Power Consumption 3.6 W 9 W 3.6 W 9 W Input Voltage 100-240 V / 50-60 Hz 100-240 V / 50-60 Hz 100-240 V / 50-60 Hz 100-240 V / 50-60 Hz Dimensions (W x H x D) 230 x 51.5 x 370 mm 230 x 51.5 x 370 mm 230 x 51.5 x 370 mm 230 x 51.5 x 370 mm Weight 1.75 kg (3.8 lb) 2.1 kg (4.6 lb) 1.75 kg (3.8 lb) 2.1 kg (4.6 lb) Origin Italy Italy Italy Italy Documentation:Analog Brochure Digital Brochure Analog Manual Digital Manual
