Temperature Control

The difficulty with viscosity measurements of hot melts and liquids at elevated temperatures has been in maintaining accurate temperature control that is consistent from sample to sample so that meaningful data could be obtained. The Brookfield Thermosel solves this problem by providing a stable, precisely controlled sample environment. This, together with the inherent accuracy of the Brookfield Viscometers, is fundamental to the Thermosel System, which produces viscosity measurements that are not only accurate but entirely reproducible.

Several factors contribute to the stable environment:

• Non-fluctuating temperature control.
• Small sample volume and insulated sample chamber which reduces temperature gradients within the sample.
• The rotating spindle, which acts as a built-in stirring device.
• The test procedure is quite straightforward. Once familiar with the system, unskilled operators can easily produce accurate, reproducible data.

Features and Benefits

• Provides control of sample temperature up to +300°C
• Programmable Controller offers single set point or up to 10 programmable set points. Temperature ramping between set points is possible if used with RheocalcT Software (Note: Requires optional cable HT-106 when QC control with RheocalcT is implemented.)
• Compatible with standard Brookfield Viscometers and DV3T Rheometers (Note: requires optional cable DVP-141 when controlled by DV3T Rheometer)
• Supplied with reusable stainless steel sample container and five disposable aluminum sample chambers
• Outputs: 0-4 Vdc for chart recorder; RS-232 for use with DV3T and/or RheocalcT

Features and Benefits

• Compact - small "footprint"
• Built-in circulator pump
• Built-in tap water cooling coil
• For use with water-jacketed devices

Why control temperature for viscosity measurement? Detecting changes in your sample's properties is valuable information for predicting your product's performance. Temperature control during viscosity measurement helps ensure accurate test results. The addition of a bath is a smart investment and the Brookfield Model 250 is the perfect complement!

Features and Benefits

• Configured for measuring multiple samples directly in the bath
• Work area accommodates 600 mL and 1000 mL beakers (cover is removable for large sample container requirements)
• Built-in tap water cooling coil
• Built-in circulator pump

The Model TC-351 Cooler is used in tandem with Brookfield Model TC-150 and TC-250 Circulating Baths to provide increased cooling capability.

Features and Benefits

• Eliminates tap water requirements on non-refrigerated baths
• Increases lower range of most baths to -20°C

Detecting changes in your sample's properties is valuable information for predicting your product's performance. Temperature control during viscosity measurement helps insure accurate test results. The addition of a Brookfield TC-550 Circulating Bath is a smart investment.
