IKA S25KV-18G: A high-precision dispersion tool for the most demanding requirements
The IKA S25KV-18G dispersion tool is designed to meet complex dispersion and homogenisation requirements in laboratory environments. Compatible with the IKA T 25 digital stirrer , this accessory stands out for its exceptional performance over a wide volume range from 10 ml to 1500 ml, offering great flexibility in the preparation of samples of various sizes. Its 18 mm stator diameter and optimised geometry enable high-quality dispersion results to be achieved, with ultimate fineness ranging from 1 to 10 µm for emulsions and 10 to 50 µm for suspensions, ensuring optimum mixture homogeneity.
Its mechanical design incorporates resistant and durable materials such as AISI 316L and AISI 302 stainless steel, silicon carbide (SIC) and FFPM elastomers, ensuring excellent chemical compatibility and resistance to aggressive solvents. This makes it perfectly suited to demanding environments in the chemical, biotechnology and pharmaceutical industries. With a pH range of 2 to 13, the tool can be used for acidic or basic samples, further expanding its field of application.
The S25KV-18G is capable of operating at speeds of up to 25,000 rpm, generating a maximum peripheral speed of 16.6 m/s, which enables fast and efficient dispersion. The rotor-stator gap of 0.25 mm optimises shear forces, contributing to rapid particle size reduction and improved homogenisation.
The device is designed for immersion use at depths ranging from 40 mm to 225 mm, with a 270 mm shaft, allowing it to work easily in different types of containers, from test tubes to laboratory beakers. It withstands working temperatures of up to 220°C and can be sterilised by all means, including wet chemical methods, ensuring rigorous hygiene and safe reuse in sensitive applications such as the processing of biological materials.
Its sealing and robustness also allow it to operate under vacuum (up to 1 mbar) or under pressure (up to 6 bar). In addition, its compliance with FDA standards ensures increased safety for applications in contact with products intended for consumption or medical use.
Compact and lightweight at only 0.5514 kg, the S25KV-18G is easy to handle, install and maintain. It is an ideal choice for laboratories looking to equip themselves with a reliable, accurate and versatile tool for their dispersion work.
