Technical Specifications

The TRG 800i is a benchtop tergotometer from Copley Scientific, designed as a laboratory-scale washing simulator for evaluating laundry and dishwasher detergent performance. It consists of up to eight miniature washing stations in a single instrument, each with a 1000 mL glass vessel and an independent agitator. Temperature, agitator speed, and cycle time are controlled through a touchscreen interface, and testing typically completes in around 15–20 minutes for laundry detergents . The specifications below cover the standard unit; the refrigeration unit, fabric attachment paddles, and dishwasher slide accessory are ordered separately.

Pre-installation Requirement:
Place the system on a rigid, level bench capable of supporting the main unit, heater, and vessels filled with 1000 mL of water each, with clearance for the touchscreen and access to all test stations. Connect the heater/circulator to a grounded power supply matching the nameplate. Fill the vessels with water adjusted for hardness and pH as required by the test method, and allow the temperature to equilibrate before adding detergent. Confirm the PT100 probe is connected and the temperature calibration is current before the first test run.

Why This Tester Belongs in a Detergent Formulation Lab

Testing detergent performance in a domestic washing machine is realistic and impractical at the same time. A full wash cycle takes 60–90 minutes for laundry and about 120 minutes for dishwashing, consumes large volumes of water and detergent, and offers limited control over test conditions. Carryover of soil or detergent between tests is a recognised problem . The TRG 800i tergotometer for detergent testing exists to solve that trade-off. Eight miniature washing stations run in parallel, each with controlled temperature, agitation, and cycle time, and a laundry detergent test completes in 15–20 minutes .

The throughput gain is the headline: up to eight times the testing capacity of a standard domestic appliance, with lower energy and material consumption . But the control is what makes the data useful. Temperature, speed, and time are set on the touchscreen and reported with set-versus-actual values throughout the run. The bidirectional agitator pattern (10–99 revolutions in either direction) simulates the reversing action of a real washing machine more closely than unidirectional agitation .

The ASTM compliance matters for labs making performance claims. ASTM D3050-07 covers soil removal from artificially soiled fabrics, and ASTM D4008-95 covers anti-soil deposition properties of laundry detergents . When a formulation change needs to be validated against a recognised method, the TRG 800i runs the test the standard describes.

For buyers sourcing through OS4U, the configuration questions are whether the refrigeration unit is needed for cold-cycle testing, whether the fabric attachment paddles belong in the order for swatch-based work, and whether the dishwasher slide accessory extends the range to dishwashing formulations. The Copley TRG 800i page lists the full accessory range.

Key Benefits

Eight stations running in parallel

The TRG 800i laboratory tergotometer runs up to eight test stations simultaneously. A formulation lab comparing eight variants, or running eight replicates, completes the work in one run rather than eight sequential tests.

Throughput up to eight times a domestic appliance

Testing completes in around 15–20 minutes for laundry detergent and 10–15 minutes for dishwasher detergent, compared with 60–120 minutes for a full appliance cycle . The time saved compounds across a screening programme.

Temperature control from ambient to 70 °C

The independent digital heater/circulator holds temperature across the range the ASTM methods specify, with the optional refrigeration unit extending down to 10 °C for cold-cycle testing . The PT100 probe monitors bath and vessel temperature with electronic calibration.

Bidirectional agitation for representative cycles

The agitator runs in a bidirectional pattern, reversing every 10–99 revolutions, to simulate the reversing action of a domestic washing machine. Unidirectional operation is also available for methods that require it .

Swatch capacity for statistically meaningful data

With the optional fabric attachment paddles (catalog number 6404A), each station accepts up to 12 swatches of 5 x 5 cm or 6 swatches of 8 x 8 cm. A full run processes 48 or 96 individual swatches simultaneously, generating the sample size needed for statistically significant performance claims .

Touchscreen control with clear reporting

The resistive touchscreen is operable with gloves and displays set versus actual parameters throughout the run. Reported data includes speed, temperature, test duration, and calibration data, output via RS-232, USB A, or USB B .

Space-saving benchtop format

The main unit measures 728 x 490 x 772 mm, with the heater and optional refrigeration unit as separate components. The system fits on a laboratory bench rather than requiring floor space for a domestic appliance .

Solving the Problems That Slow Detergent Testing Down

Struggling with the time cost of full appliance testing? Eight stations run in parallel, and a laundry test completes in 15–20 minutes. Screening that would take days on a domestic machine completes in hours.

Worried about carryover between tests? Each station has its own 1000 mL vessel and agitator. Cross-contamination between samples is contained within individual vessels, not shared across a single drum.

Needing temperature control that matches the method? The independent heater/circulator holds ambient to 70 °C, with the refrigeration unit extending to 10 °C. The PT100 probe monitors both bath and vessel temperature.

Getting agitation that does not represent a real wash cycle? The bidirectional pattern reverses every 10–99 revolutions, simulating the reversing action of a domestic machine. Unidirectional operation is available for methods that specify it.

Needing statistically meaningful sample sizes? With the fabric attachment paddles, 48 or 96 swatches run simultaneously. The sample size supports performance claims rather than anecdotal observation.

Running out of bench space for a domestic appliance? The TRG 800i is a benchtop system measuring 728 x 490 x 772 mm. It fits on a laboratory bench without the floor space and utility connections a domestic machine requires.
