Preparing Sodium Hypochlorite Solution
Corrosive Warning—Take precautions when working with sodium
hypochlorite solutions. Avoid contact with skin, eyes, and mucous
membranes. Wash affected area with water if contact with this fluid
occurs. Follow laboratory procedures for working with sodium
hypochlorite solutions. Do not autoclave the NaOCl Bottle.
Prepare 2.5%–3.5% sodium hypochlorite solution once a week, if necessary.
To prepare 2.5%–3.5% sodium hypochlorite solution:
1. Calculate the volumes of the starting sodium hypochlorite solution and DI water
needed for the desired volume of 2.5%–3.5% sodium hypochlorite solution according
to equation below.

2. Pour the calculated volume of concentrated sodium hypochlorite solution into an
appropriate final container that is labeled following laboratory procedures.
3. Pour DI water into the same container to bring the solution to the final volume.
Use this solution for applications specified in the Recommended Cleaning Agents
table (see Recommended Cleaning Agents on page 195).
