Model 325-6 is a liquid bath designed for 6 samples as for the new Cold Soak Filtration Test (CSFT), for temperatures from ambient to -30°C.

Model 325-12 has a second bath with 6 sample capacity for +25°C+/- 0.5°C (77°F +/- 1°F) warm-up per the method. Controlling to such tight stability requirement is easy with 325-12

In order to accommodate six 500 mL jars, typically available refrigerated baths get wider and deeper as size increased. The Lawler design is specific for this test method resulting in a smaller size and less than 5 gallons (20 L) bath medium.

The insulated bath is cooled by one compressor. Temperature control is provided by digital indicating controller.
