SBT®+2 | Multi-Purpose Low-Temperature Liquid Bath

Low-Temperature Pumpability | Gelation Index

The two most recognized applications of the SBT®+2 are the SBT® test (ASTM D5133 & D7110) and the Low-Temperature Viscosity Test (ASTM D2983).  The use of the patented SimAir® Test Cell allows the SBT®+2 to be held at a constant temperature during the 16-hour soak period of the D2983 test. This provides greater versatility, increased sample throughput, and improved precision over air baths and programmable liquid baths.


The versatility of the SBT®+2 bath stems from its broad cooling range, both manual and automatic temperature control, the incorporation of a viewing window, and five easily replaceable bath covers (Insert Modules). The bath now serves as a cooling source for seven different low-temperature test methods — making it a cost-effective instrument for demanding lab schedules.
