Product catalog summary

Overview
IKA overhead stirrers are designed for robust and safe stirring applications, suitable for a wide range of viscosities and volumes up to 200 liters. They include a safety circuit, clear display, and compatibility with labworldsoft® software, offering various stirring tools for different applications.

Product Series

NANO-, MICRO-, and MINISTAR Series: Compact and reliable, these stirrers maintain constant torque across the rpm range, with digital and control variants. They feature a fast response display, USB interface, and high IP54 protection.
EUROSTAR Series: Designed for complex tasks, these stirrers include digital and control versions with features like a removable wireless controller, torque trend display, and real-time temperature monitoring.
RW Series: Suitable for high viscosity applications, these stirrers are mechanically controlled, ideal for laboratory and pilot plant use.

Technical Features

All models ensure constant torque and feature a microprocessor-controlled speed governor.
Safety features include hardened glass displays and vibration sensors that stop the process if thresholds are exceeded.
Periodic software updates via USB and documentation of test parameters through control devices.

Additional Features

Integrated timer and counter functions for monitoring chemical reactions.
Temperature sensors for sample temperature measurement.
Bluetooth connectivity for weight display and parameter documentation.

Service and Support
IKA offers worldwide service with a 10-year guarantee on spare parts availability. Personalized application support is available through the IKA Application Center.

Technical Specifications
Three models are detailed with dimensions, weight, permissible ambient temperature, moisture, protection class, interface options, voltage, and frequency. All models operate within a temperature range of 5 – 40 °C and a relative moisture of 80%. Protection classes vary from IP 20 to IP 54, and all models lack USB/RS 232 interfaces. Voltage requirements are 220 – 240 V, with one model requiring 3 x 400 Y.

Product Features
The RW 20, RW 28, and RW 47 digital models are highlighted as laboratory bestsellers with digital displays, robust designs, and constant power-drive. They offer two speed ranges for universal use, with adjustable speeds and optional safety accessories.

Stirring Elements
Various stirring elements are listed, including propeller, turbine, centrifugal, dissolver, anchor, Moebius, spiral, and blade stirrers. Each type is described with shaft length, diameter, maximum speed, material, and compatibility with different models.

Applications and Performance
Stirrers are categorized by flow direction, mixing speed, shear forces, viscosity range, and specific applications. The document provides guidance on preferred geometric dimensions for optimal performance.

Accessories
A wide range of accessories is available, including flexible couplings, beaker caps, floor stands, clamps, and temperature sensors. Each accessory is identified with a unique number for easy reference.

Quality Standards
IKA overhead stirrers comply with DIN EN IEC 61010-1 and DIN EN IEC 61010-2-051 standards, ensuring safety and quality. They are suitable for reproducible procedures and can handle short-term overload operations.

FAQs
Common questions address explosion-proof systems, torque trend displays, operational duration, rotation directions, differences between electronic and mechanical stirrers, processing capacities, and vessel diameter recommendations.

Specifications and Procedures
The document provides guidelines for the operation of IKA stirrers, emphasizing the importance of the stirrer element's position relative to the vessel wall, especially for high viscosity materials. The ambient conditions required for optimal operation include a temperature range of 5°C to 40°C and humidity not exceeding 80%.

Technical Concepts
Torque: Defined as the vector product of force and lever arm, calculated as M = F * r. Torque is crucial for the relationship between mixing tool geometry, medium viscosity, and rotation speed.
Viscosity: Refers to dynamic viscosity, a measure of a fluid's resistance to flow. It is a critical parameter in mixing, emulsifying, and transferring fluids. The document lists typical viscosity values for various substances, highlighting the differences between Newtonian and Non-Newtonian fluids.

Applications and Industries
The document outlines various applications across industries such as food (butter, mayonnaise), cosmetics (creams, shampoo), pharmaceuticals, abrasives, inks, adhesives, plastics, and construction materials.
