Water Quality and pH
It is possible to produce a quality of water where the pH cannot be
measured. There is not enough ionizable material present to get a pH
reading. In fact, if you are using pH paper, the indicator in the paper
will affect the pH. We have a special Low Ion Test Kit for this circumstance.

Demineralizer, Cartridges, Bantam®
Standard Cartridge
Cartridge removes approximately 1725 grains of dissolved salts (expressed as sodium
chloride). The amount of quality water this cartridge produces depends on the
character of the starting water. The higher the level of ionizable impurities, the lower
the volume of quality water produced. For example, each cartridge will purify about
172 gallons of water containing 10 grains per gallon (as NaCl) of dissolved solids.
Catalog No. Description Price/Each
AP1043 Standard Cartridge $158.00
Ultrapure Cartridge
Cartridge removes 760 grains of dissolved salts as sodium chloride.
The quality of
the water delivered is remarkably high (million ohm resistance) and is virtually free
of carbon dioxide with a pH of 6.8 to 7.2. A science teacher would select this cartridge
only to fill the need for ultrapure quality water. Cartridge will purify about 76 gallons
of water containing 10 grains per gallon (as NaCl) of dissolved solids.

AP1044 Ultrapure Cartridge $166.00
Distilled or Demineralized Water—
Which Do I Need?
Distilled water is free of inorganic materials, suspended impurities and most
organic contaminants. To make or buy distilled water is expensive. While there
may be school laboratory applications where distilled water is required, in
many applications, demineralized water will do just as well. Demineralized
water, like distilled water, is free of inorganic materials and most suspended
contaminants. If you need organic-free water, purchase a still or distilled water.
Demineralizer, Hose Nipple Type,
Cartridges and Accessories
Demineralizer, Barnstead, Hose Nipple Type
Excellent, economical source of pure water. Hose nipple cartridges easily connect
to your water source using ordinary 3/8" laboratory tubing (not provided). No
special equipment
or hardware is required. The cartridges are single use, disposable
cartridges. A dye resin in the cartridge changes color when the cartridge is
exhausted. How many gallons of pure water will the demineralizer provide for the
science teacher? The answer will depend on your water quality. Contact your local
water department to determine the “grain” content of your water source. Select your
cartridge based on local water quality.
If you wish to mount your “Hose Nipple” Demineralizer on the wall, purchase the
Cartridge Wall Bracket Holder, AP1266. The wall holder is not furnished with the Hose
Nipple Demineralizer.
Standard Cartridge
Two bed ion exchange resin with a “grain” capacity of 1650 grains of dissolved salts.
This cartridge would be the science teacher’s first choice for volume and economy.
Catalog No. Description Price/Each
AP1267 Standard Cartridge $155.00
Ultrapure Cartridge
Ultrapure mixed bed ion exchange resin with a capacity of 915 “grains.” Even though
the “grain” capacity is low, the water produced is of “research” quality. If you might
need CO2-free water, this cartridge would be your choice. Plastic tubing is required
and available separately.
