Product Overview
The ERPM4 is a basic bench top rocking platform that is suitable for a wide range of mixing applications. The solid state speed control has a speed range of 5–50 RPM and is controlled from a single analogue control mounted on the front of the mixer.
Slow acceleration is incorporated in the drive system to reduce the risk of spillage. When required the ERPM4 can run for extended periods unattended.
A Nitrile mat is supplied fitted to the platform and is sufficient for holding containers at low speeds. For higher speeds optional racks are available.
The RR5 Universal rack pictured above has adjustable horizontal rubber covered bars that can be positioned to hold a variety of different sizes and types of containers, including test tube racks, trays, flasks etc.
Stainless steel Tulip clips are also available dedicated to conical flasks from 50ml to 2 litre.
