Overhead stirrers

The ES is an intuitive overhead stirrer ensuring safety with overload, over-current and overheating  (more)protection. Easy to install, resistant and with a small footprint, ES is your best choice for low viscosity samples. Velp ES ensures a smooth start and vigorous agitation even at maximum speed. ES can reach speeds of 1300 rpm and stir up to  15 litres. The device can manage viscosity, with a maximum of  1000 mPas. The easy chuck is easy to close and can accommodate shafts with up to 10 mm diameter and does not require any tool. Stirring speed: 50 – 1300 rpm Maximum stirring volume (H2O): 15 liters Maximum viscosity: 1000 mPas Maximum torque: 15 Ncm Construction material: technopolymer Chuck hole range: 1 – 10 mm Dimensions (WxHxD): 80 x 160 x 200 mm Weight: 1.3 kg

For drawing the material to be mixed from the top to the bottom. Local shearing forces. Generates axial flow in the vessel. Used at medium to high speeds. Stirrer Ø: 50 mm Shaft Ø: 8 mm Shaft length: 350 mm IKA tripod scale A stand with an integrated scale and data interface. The IKA scale provides increased comfort and safety for your laboratory applications. For example, your stirrer can hang on the stable support rod. The quantities of samples to be added are weighed immediately and continuously documented during the stirring process. Sample weight of up to 6 kg The intelligent tripod scale has a weighing range of up to 6 kg with a resolution of 1 g. It is therefore particularly suitable for the direct and controlled addition of sample material while stirring. Weighing range: 5 – 6000 g Weighing accuracy: ±6 g Plate dimension: 200 x 200 mm Dimensions (WxHxD): 213 x 570 x 391 mm Weight: 5.2 kg

The Hei-TORQUE 100 is a overhead stirrer with a wide speed range (10 – 2,000 rpm) and a maximum torq (more)ue of 100 Ncm. With it you can optimally stir viscosities up to 60,000 mPas or volumes up to 50 liters (H2O). The Hei-TORQUE 100 performs every stirring task with minimal noise thanks to the latest engine technology. This overhead stirrer is also very user-friendly in terms of operation and safety. The 2.4 inch display makes it very easy to set the application parameters and control the process (e.g. using the torque trend display). The safety-related start/stop touch-function serves to minimize the risk of unintentional switching on. Suitable for use in fume hoods or as a drive for reactor superstructures, the Hei-TORQUE 100 has a quick-action chuck (quick chuck with safety ring) with a diameter of 10.5 mm, which can be combined with a large number of stirring tools. Rotation speed range: 10 – 2000 rpm Rotation speed indicator: digital Speed control: electronic Maximum torque: 100 Ncm Torque indicator: symbol Overheat protection: automatic cut-out Maximum viscosity: 60000 mPa s Stirring capacity (H2O): 50 l Throught-shaft design: yes Maximum shaft diameter: 10.5 mm Including tripod and a PR 31 Ringed Pitched-Blade Impeller Due to its blade dimensions, the ringed pitched-blade impeller PR 31 is ideal for solutions, emulsions and suspensions in vessels with the following characteristics: Ideal vessel diameter: 83 – 165 mm Ideal ground clearance: 17 – 33 mm Ideal filling level: 83 – 165 mm Ideal volume: 400 – 3500 ml The ringed pitched-blade impeller PR 31 has a total length of 400 mm and is made of stainless steel. Its stirring shaft has a diameter of 8 mm.
