Understanding the HPQA Helipath Quick Action Stand
The Helipath Quick Action Stand is a motorized laboratory stand developed by AMETEK Brookfield for viscosity and consistency measurements involving materials that can be difficult to test using conventional fixed-height spindle arrangements.
When a suitable Brookfield viscometer is equipped with a compatible T-bar spindle, the HPQA can move the rotating spindle vertically through the sample, creating a helical measurement path. This allows the spindle to measure undisturbed portions of the sample, minimizing the effects of channel formation during viscosity testing.
The HPQA also provides quick-action positioning for standard laboratory operations. Its motorized movement can reach speeds of up to 40 mm/s during quick positioning, while the standard Helipath test movement is much slower. Programmable positions and one-touch Home movement can simplify sample changes and routine test preparation.
When integrated with a compatible DV2Plus instrument and the required firmware, users can coordinate stand movement with programmed viscosity tests through the viscometer interface.
For laboratories working with pastes, creams, gels and other challenging materials, this combination can improve test setup consistency and reduce repetitive manual positioning.
Why Viscosity Measurement Matters in Food Manufacturing
Viscosity describes a material’s resistance to flow. In food manufacturing, it influences product texture, spreadability, pouring behaviour, processing performance and consumer perception.
However, many food products do not behave like simple liquids. Peanut butter, mayonnaise, chocolate spreads and thick sauces may exhibit non-Newtonian behaviour, meaning their apparent viscosity can change with the applied shear conditions. Some are also thixotropic, meaning their structure and apparent viscosity change over time under continued shearing.
For this reason, a viscosity result should be interpreted alongside the test method, spindle, rotational speed, temperature, sample preparation and measurement time.
The appropriately configured Brookfield viscometer enables food testing laboratories to perform consistent measurements and evaluate product samples using standardized testing conditions. The objective is not simply to obtain a viscosity number; it is to produce meaningful data that supports product development and quality decisions.
1. Peanut Butter Viscosity Testing
Peanut butter is a challenging material to measure because its consistency depends on several factors, including oil separation, particle size, formulation, stabilizer concentration, temperature and processing history.
A product that is too thick may be difficult to spread, while one that is too thin or oily may fail to meet the manufacturer’s intended texture specifications. Changes in viscosity can also indicate differences between production batches or storage conditions.
Benefits of Using the DV2Plus RV Viscometer with the HPQA Stand
For suitable peanut butter formulations, a compatible T-bar spindle and Helipath movement can help the instrument measure consistency at different positions within the sample. The helical path reduces the tendency to repeatedly measure along the same channel, which can be particularly relevant for materials that do not readily flow back around the spindle.
Food manufacturers can use a controlled testing procedure to:
• Compare viscosity between production batches.
• Evaluate changes associated with formulation adjustments.
• Monitor the effect of storage and temperature on consistency.
• Support research into spreadability and texture.
• Establish internal acceptance limits for routine quality control.
For meaningful comparisons, laboratories should use a consistent sample container, filling depth, temperature, spindle, rotational speed and measurement timing.
Peanut butter can contain particles and may separate during storage, so sample handling must be carefully defined. The selected spindle and testing method should be validated for the particular product.
2. Mayonnaise Viscosity Measurement
Mayonnaise is an oil-in-water or, more precisely in conventional formulations, a highly concentrated oil-in-water emulsion whose texture depends on its formulation and manufacturing process. Its consistency influences spoonability, spreadability, appearance and performance in packaged foods.
Factors such as oil content, emulsifier system, droplet size distribution, processing intensity and temperature can affect the measured viscosity.
Improving Mayonnaise Quality Control
The AMETEK Brookfield DV2Plus RV Viscometer can help laboratories measure mayonnaise viscosity under defined conditions. When the sample characteristics and test method are suitable, a T-bar spindle and HPQA stand can support measurements of thick mayonnaise formulations that are difficult to evaluate using conventional fixed-height arrangements.
Potential applications include:
- Comparing mayonnaise formulations during product development.
- Monitoring batch-to-batch consistency.
- Evaluating the effects of ingredient substitutions.
- Investigating viscosity changes during storage.
- Supporting internal product specifications.
A consistent testing protocol is especially important for mayonnaise because its apparent viscosity may depend on the applied shear and the time elapsed after mixing or sample preparation.
Laboratories should also avoid introducing air bubbles during sampling, as entrained air can influence readings. Sample temperature and equilibration time should be controlled to ensure that measurements from different batches are comparable.
3. Emulsified Sauces and Condiments
Emulsified sauces cover a broad category of products, including creamy dressings, sandwich sauces, dipping sauces and other formulated condiments. Their viscosity requirements can vary considerably depending on how they are intended to be used.
A sauce designed for squeezing from a bottle may require different flow characteristics from a thick dipping sauce or a creamy sandwich spread. Manufacturers therefore need a reliable way to compare product consistency with defined targets.
Applications in Sauce Manufacturing
The DV2Plus RV Viscometer offers adjustable rotational speeds, allowing laboratories to investigate product behaviour under selected test conditions. With a suitable spindle configuration, the HPQA can provide controlled positioning for samples that are paste-like or difficult to measure using a conventional stationary spindle arrangement.
Manufacturers can use viscosity testing to:
- Compare the consistency of different sauce formulations.
- Assess the effects of stabilizers and thickeners.
- Investigate processing-related variations.
- Monitor product consistency during routine production.
- Support research into pouring and dispensing characteristics.
Viscosity measurement should be considered part of a wider quality-control programme. Depending on the product, additional tests may be necessary to evaluate emulsion stability, separation, texture, pH and microbiological quality.
Because sauces vary widely in particle content and flow behaviour, the correct spindle and measurement method should be selected for each application rather than assuming that one setup will suit every sauce.
4. Chocolate Spread Consistency Testing
Chocolate spreads combine ingredients such as sugar, fats, cocoa solids, milk solids and other formulation components to produce a characteristic creamy texture. Their consistency affects spreadability, mouthfeel, filling operations and consumer satisfaction.
Viscosity can vary with temperature, fat composition, particle size, storage conditions and the material’s processing history. A chocolate spread that is too firm may be difficult to spread, while a formulation that is too fluid may not deliver the desired product experience.
Evaluating Chocolate Spread Viscosity
The DV2Plus RV Viscometer with a compatible T-bar spindle and HPQA stand can be considered for suitable chocolate spread consistency measurements, particularly where the sample behaves as a thick paste.
A controlled test method can help manufacturers:
- Compare batches against an established viscosity profile.
- Evaluate the effect of ingredient or fat-system changes.
- Investigate temperature-related consistency differences.
- Support formulation development and product optimisation.
- Improve consistency checks during production.
Chocolate-based products can be sensitive to temperature and may change structure as they cool or warm. Laboratories should define the measurement temperature and allow samples to equilibrate before testing.
Important application note: The DV2Plus RV with HPQA is a rotational viscosity and consistency measurement configuration. It should not automatically be treated as a substitute for specialised chocolate rheology, yield-stress or process-viscosity methods. The suitability of the spindle geometry and test protocol must be confirmed for the specific chocolate spread and the results required.

How to Choose the Right Viscosity Testing Method
Selecting the correct equipment is only the first step. A reliable viscosity result requires a method designed around the material being tested.
Step 1: Define the Product
Identify whether the sample is a free-flowing liquid, thick emulsion, paste or material containing suspended particles. This helps determine whether conventional spindles, T-bar spindles or another accessory should be considered.
Step 2: Establish the Measurement Objective
Decide whether the objective is routine batch comparison, formulation development, process troubleshooting or a more detailed investigation of flow behaviour.
Step 3: Control Sample Temperature
Temperature can have a significant effect on food viscosity. Define the target temperature, sample conditioning procedure and time allowed for equilibration.
Step 4: Select the Spindle and Speed
Choose a compatible spindle and speed that provide an appropriate measurement range and torque response. The RV model’s suitability should be verified against the expected viscosity of the product.
Step 5: Standardise Sample Preparation
Use consistent containers, fill levels, mixing procedures and waiting times. Avoid introducing air bubbles and document any steps that may change the sample’s structure.
Step 6: Establish Repeatability
Test replicate samples and evaluate the variation in results. Once the method is validated, document it as a standard operating procedure for routine testing.
These steps help laboratories produce useful, comparable data instead of relying on isolated viscosity readings.
