Product Description
When your experiments demand precision, this 45% sodium hydroxide solution in AR grade delivers consistent results every time. Whether you’re a student setting up your first titration or a researcher fine-tuning a synthesis protocol, this lab-grade chemical offers the purity and reliability you need.
The analytical reagent grade ensures minimal impurities, making it perfect for sensitive applications where accuracy matters. From adjusting pH levels to serving as a strong base in organic reactions, this versatile solution handles it all. The 45% concentration provides an optimal balance between strength and ease of handling in laboratory settings.
What sets this product apart is its consistency. Each batch undergoes rigorous quality checks to maintain the exact 45% concentration, so you can trust your calculations without second-guessing. The solution comes ready-to-use, eliminating the need for dangerous pellet handling while maintaining all the reactive properties of solid NaOH.
For researchers working on saponification reactions, this solution offers precise control over reaction rates. Students performing acid-base titrations will appreciate how the consistent concentration simplifies their calculations. Even in cleaning protocols for glassware, this solution proves more effective than diluted alternatives while being safer than handling concentrated pellets.
At eqipped, we understand that lab supplies aren’t just products – they’re tools that enable discovery. That’s why we source this sodium hydroxide solution from trusted manufacturers and maintain strict storage protocols to ensure it reaches you in perfect condition. Whether you’re stocking a university lab or setting up a home research station, this solution gives you professional-grade performance without compromise.
Key Applications in Laboratory Settings
This versatile chemical finds use across numerous lab applications. In analytical chemistry, it serves as a primary standard for acid-base titrations. Organic chemists rely on it for ester hydrolysis and other base-catalyzed reactions. Biochemistry labs use it for protein denaturation studies and DNA extraction protocols.
The solution’s consistency makes it particularly valuable for educational settings. When students perform their first titrations, having a reliable base solution means they can focus on learning technique rather than questioning their reagents. The 45% concentration hits the sweet spot – strong enough for most applications yet easy to measure and dilute when needed.
For cleaning applications, this solution effectively removes organic residues from glassware without the hazards of handling solid NaOH. Many labs keep it on hand for routine maintenance of volumetric flasks and burettes, where even trace contaminants can affect results.
Safety and Handling Considerations
While extremely useful, sodium hydroxide requires proper handling. Always wear appropriate PPE including chemical-resistant gloves and eye protection when working with this solution. The liquid form reduces dust hazards compared to pellets but still demands respect.
Store the solution in a cool, well-ventilated area away from acids and organic materials. The plastic bottle provides good chemical resistance, but always ensure the cap is tightly sealed after use to prevent concentration changes from evaporation.
In case of skin contact, immediately rinse with plenty of water and seek medical attention if irritation persists. For eye exposure, flush with water for at least 15 minutes and get medical help promptly. Keep this solution out of reach of children and untrained personnel.
Why This Solution Stands Out
Not all sodium hydroxide solutions are created equal. This AR grade product undergoes additional purification steps to remove trace metals and other contaminants that could interfere with sensitive analyses. The 45% concentration represents an industry standard that balances reactivity with practical handling.
The solution’s stability means you can rely on consistent performance throughout its shelf life. Unlike some competitors’ products that may show concentration drift over time, this solution maintains its specified strength when stored properly. This reliability translates to more reproducible results in your experiments.
For educational institutions, the consistent quality means students get predictable outcomes in their experiments, reinforcing proper laboratory techniques. Research labs appreciate the batch-to-batch consistency that eliminates variables in their protocols.
FAQs
What is the shelf life of this sodium hydroxide solution?
When stored properly in its original container at room temperature, this solution maintains its specified concentration for at least 12 months from the date of manufacture.
Can I use this solution for soap making?
While technically possible, we recommend using food-grade sodium hydroxide for soap making. This AR grade solution contains additives that make it suitable for laboratory use but not ideal for cosmetic applications.
How should I dispose of unused solution?
Neutralize with a weak acid like acetic acid before disposal according to your institution’s chemical waste protocols. Never pour concentrated sodium hydroxide down drains without proper neutralization.
Is this solution suitable for pH meter calibration?
Yes, the consistent concentration makes it excellent for preparing calibration buffers. However, for official calibration standards, you may need certified reference materials.
What’s the difference between AR grade and technical grade sodium hydroxide?
AR grade undergoes additional purification to remove trace impurities, making it suitable for analytical applications. Technical grade may contain higher levels of contaminants but costs less for industrial uses.
Risk Note for High-Risk Chemical:
WARNING: Sodium hydroxide is a strong corrosive chemical. Causes severe skin burns and eye damage. May be fatal if swallowed. Handle with extreme care using proper protective equipment. Keep away from children and incompatible substances.
