SB+2 | Scanning Brookfield Plus Two

Low-Temperature Pumpability | Gelation Index

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

The versatility of the SB+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.
