Overview of Techne Fluidized sand baths |

Fluidized baths
offer an open work area
with the potential for a wide range of applications where a
stable temperature environment is required. They use a media that
never needs replacing and doesn't evaporate, are safe to operate and
thus a logical choice over molten salt baths, high temperature oil
baths and ovens and furnaces.

| Model | Select a unit | Range | Working area | Stability | Features |
| Basic Laboratory Range |
![]() |
50ºC to
600ºC (122ºF to 1112ºF) |
From 7.0" x 3.5" to 9.0" x 15.0" (diameter x depth) | ±0.3 at 50ºC | Lower cost & smaller footprint - good choice for general purpose temperature sensor calibration and heat treatment. |
| Precision FB08 Range |
![]() |
50ºC to
700ºC (122ºF to 1292ºF) |
6.5" x 15.0" (diameter x depth) | ±0.08ºC
full range normal mode ±0.008ºC full range dead bed mode |
Excellent stability and uniformity make it a good choice for PRT & SPRT comparison calibrations as well as stringent requirements for heat treatment by medical device manufacturers. |
| Industrial Plastic Burnoff range |
![]() |
50ºC to
600ºC (122ºF to 1112ºF) |
From 10.2" x 12" to 10.2" x 26.0" (diameter x depth) | ±3.0 up to 600ºC | Primary choice of plastics manufacturers for cleaning residual resin and material from tools, dies, extruder screws and plates. Large working area. |

| Stability & uniformity | good | fair | fair | good |
| Safety | good | poor (highly volatile) |
good | poor (fumes, odors, splashing & hazardous fluids) |
| Efficiency & quench recovery | good | good | poor (heat is lost when opening doors) |

| Setup & ongoing costs | good | fair (must add salt as it's lost on items put in bath) |
good | poor (must add fluid as it's lost in use & evaporation. Fume exhaust required) |
| Notes: | Non-abrasive to product immersed in the bath | must clean off product after being placed in bath | Slow heat transfer | must clean off product after being placed in baths - environmental impact of used fluids |
