How to Use Your Utility Bath

Your new utility bath has arrived and you’re ready to start using it in your lab. The first step in set up is location. Place your water bath on a table or bench that is level. It should be located in an area that does not have drafts or wide temperature variations (for example, near furnace, heater, or air conditioning vents).

Filling it Up

When samples are placed the bath, the liquid level is about one inch from the top. To make sure your temperature readings are accurate, the liquid level should not drop to less than two inches from the bottom of the unit.

Using distilled water in the unit is preferred, but other fluids can be used depending on your application. Fluids should be compatible with the bath materials and meet health and safety requirements. When using water, include a few drops of Lab Algicide to prevent algae formation.

Do NOT use these fluids in your bath:

• Flammable fluids
• Deionized water
• Chlorides or bleach
• Auto antifreeze with additives
• Most photographic solutions
• Strong concentrations of any acid or bases
• Any acid with the following elements in their formulas: chlorine (CL), Fluorine (F), Sulfur (S), Chromium salts

Also, stay within the fluid’s normal range to maintain the best temperature stability and low vaporization. When the fluid reaches its high temperature extreme, it may need a fume hood to prevent the build-up of vapors inside the lab. Fluid lost from vapor will have to be replenished frequently. Take caution to stay well below a fluid’s flashpoint.
