Adapters

Small Sample
The small sample is for rheological evaluation where sample volume is limited.

The Small Sample Adapter (SSA), consisting of a cylindrical sample chamber and spindle, provides a defined geometry system for accurate viscosity measurements of small sample volumes in the order of 2 to 16 mL at precise shear rates. The Small Sample Adapter's rheologically correct cylindrical geometry provides extremely accurate viscosity measurements and shear rate determinations.

The design of the SSA allows the sample chamber to be easily changed and cleaned without disturbing the set-up of the viscometer or temperature bath. This means that successive measurements can be made under identical conditions.

The sample chamber fits into a flow jacket so that precise temperature control can be achieved when a Brookfield circulating temperature bath is used. Direct readout of sample temperature is provided using sample chambers with embedded RTD temperature sensors connected to the DV-I Prime (w/temperature option), DV2T, or the DV3T Ultra. Working temperature range for the SSA is from 1°C to 100°C.

Features & Benefits:

• For rheological evaluation of materials where sample volume is limited.
• Sample chamber easily changed.
• Optional disposable chamber also available.
• Water jacket allows rapid and precise temperature control of sample.
• Simultaneous sample temperature measurement is possible by ordering embedded temperature probe in sample chamber.

Enhanced UL

The Enhanced Brookfield UL Adapter is used with any standard Brookfield Viscometer and Rheometer to make accurate and reproducible measurements on low viscosity materials. Newtonian and non-Newtonian materials can be measured. It is most commonly used with the LV series instrument (at 60 rpm, these models have a full scale range of 1-10 cP with the UL Adapter). The UL Adapter consists of a precision cylindrical spindle rotating inside an accurately machined tube. Its rheologically correct cylindrical geometry provides extremely accurate viscosity measurements and shear rate determinations. The tube has a removable end cap which allows the open ended tube to be used in a beaker or tank. With the cap in place, the closed tube can be immersed in a temperature bath or used with the ULA-40Y water jacket for precise temperature control. Working temperature range is from -1°C to 100°C.

Features & Benefits:

• Ideal for low viscosity materials.
• Stainless steel parts are easily cleaned.
• Removable cap of low density polyethylene can be considered disposable for one-time use if required.
• Reduces measuring range to as low as 1 cP, depending on viscometer used.
• Small sample size: 16 mL.
• Simple attachment to a standard Brookfield Viscometer or DV3T Rheometer.
• Cylindrical geometry provides defined shear rates for detailed product analysis.

DIN
The DIN is for limited sample volume.

The DIN Adapter Accessory (DAA) is a cylindrical spindle geometry that conforms to the DIN 53019 specification. Three spindles and three chambers are provided. The DAA can be attached to any standard Brookfield Laboratory Viscometer/Rheometer.

Features & Benefits:

• Complies with DIN 53019 requirements for test geometry. DIN is the German equivalent to the U.S. ASTM Standards.
• Designed to provide an alternative for those customers having limited sample volume. Requires 16 mL to 20 mL sample size.
• Cylindrical geometry provides defined shear rates.
• Comes with three spindles and two chambers for measurement range of 1 to 50,000 cP.

Spiral
A Pump-type Sensor That Directly Measures Viscosity Of Pastes

Designed for measuring the viscosity of heavy paste-like materials and non-flowing products. Provides variable shear rates for detecting pseudoplastic and thixotropic behavior when used with standard Brookfield Viscometers and the DV-III Ultra Rheometer.

The Spiral Adapter has an inner, threaded spindle surrounded by a concentric outer cylinder. This combination causes the sample to be continually pumped up through the Spiral Adapter. The material reaches a steady state of flow during which viscosity is measured. The steady-state measurement is less sensitive to sample handling and minor material variations than other viscosity measuring methods.

At its various rotating speeds, the Brookfield Viscometer/Rheometer provides viscosity data at different shear rates. The resulting rheogram from an up/down speed ramp supplies important information on the psuedoplastic and thixotropic behavior of the test material.

Features & Benefits:

• Performs measurements compatible with industry specifications.
• Provides viscosity data that show pseudoplastic and thixotropic properties of test samples.
• Delivers repeatable measurements within ±2%.
• Works with any standard Brookfield Viscometer/Rheometer.
• Simple and fast to operate; easy to clean.
• Optional software computes shear sensitivity factor.
