Step 1:Clarify your needs and specifications
Before starting to purchase,please be sure to clarify your purchasing purpose,which will directly determine what specifications of products you need to purchase.
Purity/Grade:
Industrial grade:suitable for applications with low purity requirements such as construction,sewage treatment,and neutralization of acidic soils.
Reagent grade/analytical grade:used for school experiments and scientific research analysis,with high purity requirements.
Packaging and Quantity:
Packaging form:usually bagged powder.Confirm whether it is a large package of 25kg/bag or a small package of 500g/1kg.
Online platforms are a mix of good and bad,and learning to distinguish is the core of ensuring transaction security.
View merchant qualifications:
Enterprise certification:Priority should be given to stores with the"Enterprise Certification"logo.
Reputation and Age:Check the establishment time,reputation level,and buyer reviews(especially"follow-up reviews"and"image reviews")of the store.
Related certificates:If purchasing reagent grade products,it is necessary to require the seller to provide corresponding qualification certification documents,such as food production license,chemical safety technical specifications,etc.
Carefully read the product description:
Key information:Confirm whether the product name,chemical formula,purity,grade,production date/batch number,execution standards,and other information are complete.
Physical pictures:View pictures taken of physical objects,not network diagrams.
Effective communication with customer service:
Before placing an order,proactively communicate with customer service to confirm product specifications,inventory,shipping time,transportation methods(especially logistics restrictions),etc.

When receiving the goods,first check the outer packaging for signs of damage,moisture,or leakage.
After unpacking,check if the product matches the description(such as packaging and label information).
Storage:Calcium hydroxide should be stored in a cool,dry,and well ventilated place,sealed to prevent it from reacting with carbon dioxide in the air to form calcium carbonate and becoming ineffective.Be sure to stay away from acids and food.
