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

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.

  • Versatile liquid bath for analyzing lubricants and fluids meeting numerous low-temperature test methods.
  • Easily replaceable Insert Module for each test.
  • Programmable & Manual bath temperature controls.
  • Self-contained refrigeration system capable of cooling to -70°C.
  • Generates the Gelation Index & Gelation Index Temperature according to ASTM D5133 and D7110 methods.
  • Designed for use with patented SimAir® Test Cells for Low-Temperature Viscosity D2983 testing.
  • Ideal for low-temperature work with fresh, sooted, or highly oxidized oils, ATFs, and fuels.
