VRM Cleaning Module
The VRM cleaning module enables the fully automatic cleaning and drying of the viscometers, preventing the user of getting in direct contact with those harmful substances. The analysis of many polymers requires the use of hazardous solvents such as phenol / dichlorbenzene (e.g. for PET), metacresol or concentrated sulfuric acid (e.g. for PA).
Depending on the configuration, one or two viscometers can be connected and two different cleaning liquids can be set separately. The VRM 4 HT series is designed to handle even very hot samples of up to 160 °C or highly viscous samples with 1,000 mm²/s. The glass viscometers are cleaned by using cleaning solvents and dried with a volatile solvent and ambient air.
The VRM 4 S enables cleaning even with concentrated sulfuric acid.
VRM Cleaning Module Special Features:
- Automatic (online) rinsing of the viscometer
- Inert and corrosion-free for all standard solvents
- Individual specification of cleaning procedures using PC software
- No external connections necessary
- Two different rinsing agents (the first for cleaning, the second for drying)
- VRM 4 for use with most common solvents, VRM 4 S with resistance to sulfuric acid, VRM 4 HT for high temperatures and high viscosity (external suction pump VRP (LMRZ809) necessary)
