Re: [Histonet] Tap Water in Staining
|From:||email@example.com (Pam Marcum)|
Tap water is fine in most cases. It is wise to know a baseline pH so you have something to look at if it changes over time, and it can. Tap water can change with the amount of chlorine added at different times of the year. When we have heavy rains here and when I lived in St Louis years ago it could mean the slides would literally bleach out due to higher chlorine levels in running water. Then we had to change again when they reduced it. One area of California has tap water at 8.0 to 8.5 pH which can over blued or change the colour with long rinses.
Hope this helps.
