FAQs
What is the shelf life of Sodium Acetate Trihydrate for Molecular Biology?
When stored properly in its original container at room temperature, this product maintains stability for at least 2 years from the date of manufacture.
Can this be used for food or pharmaceutical applications?
No, this is specifically formulated for molecular biology applications and is not intended for food, drug, or cosmetic use.
How do I prepare a 3M sodium acetate solution?
Dissolve 40.8 g of sodium acetate trihydrate in 80 ml of water, adjust pH if necessary, then bring to 100 ml final volume with water.
Is this product sterile?
The product is not sterile as supplied. For applications requiring sterility, you should filter-sterilize the prepared solution using a 0.22 μm membrane.
What’s the difference between anhydrous and trihydrate forms?
The trihydrate form contains three water molecules per sodium acetate unit, making it more soluble but with a slightly lower molar concentration per gram compared to the anhydrous form.
