Small and Large Marshall Water Baths are specially designed for conditioning of asphalt Marshall Stability specimens, but are useful in other lab applications. Precision electronic controls to regulate fluid temperatures from ambient to 140°F (60°C ±1% of set-point, well within specified tolerances. Temperatures up to 212°F (100°C) can be achieved. Digital temperature displays operate in either °F or °C. Built-in variable speed magnetic stirrer provides optimum heat distribution and uniformity and an external drain valve makes it easy to empty the baths.
Both Water Baths feature sturdy, long-lasting all-stainless steel construction with 14-gauge tanks and covers with 20-gauge cases. The water baths are fully insulated and include a perforated 14-gauge bottom support shelf which permits 2in (51mm) water above and below specimens.
MSA-130 Small Marshall Water Bath accept five 6in (152mm) or twelve 4in (102mm) diameter specimens. MSA-130S is identical to the MSA-130, but includes a gas strut to assist with opening of the lid.
MSA-131 Large Marshall Water Bath holds nine 6in (152mm) or sixteen 4in (102mm) diameter specimens and includes a gas strut-assist feature for easy lifting of the lid.
