Calcium Chloride Fused
Calcium Chloride Fused (Product Code: SCL-801/145) is anhydrous calcium chloride, made by melting the hydrated crystals to drive off their water, used as a drying agent in desiccators, guard tubes and gas-drying towers in chemistry laboratories. Because it pulls water vapour strongly from its surroundings, school, college and research labs keep it in constant use; it comes in a 500 gm pack of analytical reagent grade with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a lab chemicals supplier in India.

What Is Fused Calcium Chloride Used For?
In a desiccator, the lower compartment is filled with fused calcium chloride, and crucibles or weighed samples placed on the plate above cool without taking up moisture before they are weighed. That matters in experiments such as finding the water of crystallisation of a salt. For guard tubes, pieces of the salt are packed loosely between cotton-wool plugs in a calcium chloride tube of borosilicate glassware and fitted to the upper end of a condenser or flask, so that air entering the apparatus is dried first. Gases such as oxygen, hydrogen and carbon dioxide can be dried by passing them through a U-tube or absorption tower filled with it.
It should not be used to dry ammonia, alcohols or amines, because it combines with them; quicklime is the usual choice for ammonia. When the charge turns damp, sticky or starts to liquefy, it has reached its capacity and should be replaced. Dissolving it in water releases heat and the dust irritates eyes, so use a dry spatula and goggles, and keep the container tightly sealed between uses.

Frequently Asked Questions
Who supplies Calcium Chloride Fused SCL-801/145?
Calcium Chloride Fused (SCL-801/145) is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, Ambala, Haryana, India. The company sources this drying agent for teaching and research laboratories and supplies it with an MSDS to buyers in India and international markets.
What does fused mean in Calcium Chloride Fused?
In Calcium Chloride Fused, the word fused means the salt has been melted to remove its water of crystallisation, leaving anhydrous calcium chloride that absorbs moisture strongly. That is why it is used for drying rather than for making up solutions of known strength.
How much Calcium Chloride Fused is in one pack?
One pack of Calcium Chloride Fused contains 500 gm, listed as analytical reagent grade and supplied with an MSDS. Laboratories that recharge several desiccators and guard tubes regularly can ask for more than one pack in the same quotation.
Can Calcium Chloride Fused dry ammonia gas?
No. Calcium Chloride Fused combines with ammonia, so it is unsuitable for drying that gas; quicklime is the usual choice. It also reacts with alcohols and amines, so choose a different drying agent for those compounds as well.
How can I tell when Calcium Chloride Fused needs replacing?
Replace Calcium Chloride Fused when the pieces look wet, stick together or begin to dissolve, because the drying capacity is then used up. Regular checks of desiccators and guard tubes keep weighed samples and moisture-sensitive reactions dry.
What is the shelf life of Calcium Chloride Fused?
Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. Keep unopened Calcium Chloride Fused sealed in a dry place and reseal an opened container quickly each time.
Is Calcium Chloride Fused the same as the earlier Calcium Choride Fused listing?
Yes. Calcium Chloride Fused (SCL-801/145) is the same product that earlier appeared as Calcium Choride Fused; only the spelling of the name has been corrected. The product code, pack size and web address of this page stay unchanged.
