Product Description
Potassium hydroxide (KOH) pellets from Avantor’s GPR RECTAPUR™ line are a staple in laboratories and industrial settings. Known for their high purity and consistent performance, these pellets dissolve rapidly in water, releasing heat and forming a strongly alkaline solution. Whether you’re conducting acid-base titrations, synthesizing biodiesel, or adjusting pH levels in research, this lab-grade KOH ensures reliable results every time.
Unlike lower-grade alternatives, GPR RECTAPUR™ potassium hydroxide undergoes rigorous quality checks to minimize impurities like sodium, heavy metals, and carbonates. This makes it ideal for sensitive applications where precision matters. The pellet form also offers easier handling and dosing compared to flakes or powders, reducing waste and improving safety in your workflow.
At eqipped, we understand the needs of students, researchers, and educators. That’s why we source only trusted brands like Avantor to provide chemicals that meet international standards. Whether you’re stocking your university lab or a small-scale research facility, these KOH pellets deliver the purity and performance you expect.

Key Applications of Potassium Hydroxide Pellets
Potassium hydroxide is one of the most versatile alkalis in chemistry. Here’s how researchers and industries use it:
1. Titration and Analytical Chemistry
As a primary standard for acid-base titrations, KOH pellets help determine the concentration of unknown acids with high accuracy. Their low moisture content ensures stable molar solutions, critical for quantitative analysis in educational and research labs.
2. Saponification and Soap Making
In organic chemistry labs, KOH is preferred over sodium hydroxide (NaOH) for producing softer, liquid soaps. Students studying esterification and hydrolysis reactions often use these pellets to demonstrate saponification processes clearly.
3. pH Adjustment in Buffers
Biochemistry and molecular biology experiments require precise pH control. KOH pellets allow gradual adjustment of solutions without introducing contaminants, making them ideal for preparing buffers for DNA/RNA extraction or protein assays.
4. Biodiesel Production
Researchers working on renewable energy projects use KOH as a catalyst in transesterification reactions. The pellet form simplifies measuring exact quantities needed for small-scale biodiesel synthesis in academic setups.
5. Surface Cleaning and Etching
In materials science labs, KOH solutions etch silicon wafers and clean glassware by dissolving organic residues. The GPR RECTAPUR™ grade ensures no metallic impurities interfere with sensitive surface treatments.
Safety and Handling Guidelines
Potassium hydroxide is a highly corrosive substance. Always follow these precautions:
Storage: Keep the container tightly sealed in a cool, dry place away from acids and moisture. Store in a corrosion-resistant cabinet labeled for alkalis.
Handling: Wear nitrile gloves, safety goggles, and a lab coat. Use in a fume hood when preparing solutions to avoid inhaling vapors.
First Aid: In case of skin contact, rinse immediately with plenty of water for at least 15 minutes. For eye exposure, flush with water and seek medical attention. If ingested, do NOT induce vomiting; give water or milk and call a poison control center.
Disposal: Neutralize with a weak acid (e.g., acetic acid) before disposal. Follow your institution’s chemical waste guidelines.
Risk Note: Causes severe skin burns and eye damage. Harmful if swallowed or inhaled. Keep out of reach of children.
Why Lab-Grade Matters
Not all potassium hydroxide is created equal. The GPR RECTAPUR™ grade from Avantor is specifically designed for laboratory use, offering:
Consistent Purity: Minimum 85% KOH content with tightly controlled impurities, ensuring reproducible results in experiments.
Lot Traceability: Each batch comes with a certificate of analysis, allowing researchers to verify specifications for critical applications.
Low Carbonate Content: Unlike technical-grade KOH, these pellets have minimal carbonate formation, preventing errors in titrations.
For students learning volumetric analysis or researchers developing new chemical processes, using lab-grade KOH eliminates variables that could skew data. At eqipped, we prioritize quality so you can focus on your work with confidence.
Choosing the Right Pack Size
This 1 kg pack is perfect for:
University and College Labs: Sufficient for multiple student batches conducting titrations or synthesis experiments over a semester.
Small Research Groups: Ideal for projects requiring frequent but moderate KOH usage, reducing the need for frequent reordering.
Pilot-Scale Testing: Startups and educators testing biodiesel or soap formulations can scale up from bench trials without excess inventory.
If your lab consumes larger quantities, consider bulk packaging options available at eqipped to optimize cost and storage.
FAQs
What is the difference between potassium hydroxide pellets and flakes?
Pellets are denser and less prone to absorbing moisture, making them easier to handle and measure accurately. Flakes dissolve slightly faster but can clump in humid conditions. For most lab applications, pellets are preferred for their stability.
Can I use these KOH pellets for making soap at home?
While these are high-purity lab-grade pellets, they can be used for soap making. However, ensure proper safety gear and ventilation, as the reaction with fats/oils releases heat and fumes. For large-scale soap production, industrial-grade KOH may be more cost-effective.
How do I prepare a 1M KOH solution using these pellets?
To make 1 liter of 1M KOH solution, dissolve 56.11 grams of pellets in distilled water, then dilute to volume. Always add KOH to water slowly while stirring to prevent violent reactions. Use a volumetric flask for accuracy.
What should I do if my KOH pellets turn yellow or clump together?
Yellowing or clumping indicates moisture absorption or carbonate formation. While it may still be usable for some applications, it’s best to replace it for precise work. Store future batches in an airtight container with desiccants.
Does eqipped provide certificates of analysis for this product?
Yes, certificates of analysis (CoA) are available upon request for all Avantor products, including these KOH pellets. Contact our support team with your order details to receive the documentation.
