::Characteristics::

Types: DL-1, DL-2, DL-3.
Shape: glass-like pellets or lumps.
Color: blue.
Nontoxic, odorless.
In comparison with ordinary blue gel, blue silica gel Dl. possesses the feature of quanti tative discoloring, i.e., when adsorbing a certain amount of moisture, it begins coloring and does not stop coloring until a specified amount of moi.sturc its absorbed.
It is wideIy used as humidity indicator and drier in judging if the adsorption & drying process is up to the requirements.

::Use::

1. Used for absorbing moisture of instruments,
2. After absorbing moisture, it turns blue into red, visually indicating the relative humidity of the given environment..
3. When being used with ordinary silica gel or drier, it indicates to which extent the drier absorbs the moistures and judges the relative humidity of a given environment.
4. Used to judge if the humidity of a environment is up to the specified requirements and to determine if the adsorbent or drier ceases to be effective.
