Product Description
Potassium hydroxide (KOH) pellets are a staple in molecular biology labs, offering precise alkalinity control for critical applications. This 85% pure, lab-grade KOH is specifically formulated for research where consistency and purity matter. Whether you’re working on nucleic acid extraction, protein denaturation, or buffer preparation, these pellets dissolve quickly and evenly, ensuring reliable results every time.
Researchers and students alike trust this grade for its low impurity profile, which minimizes interference in sensitive assays. The pellet form makes handling safer and more accurate than flakes or solutions, reducing waste and exposure risks. For educators demonstrating titration experiments or pH studies, these KOH pellets provide a stable, long-shelf-life option that’s easy to store and dispense.
At eqipped, we understand the demands of modern labs. That’s why we source this KOH directly from trusted manufacturers like CDH, ensuring you receive a product that meets international molecular biology standards. Each batch is tested for heavy metals and other contaminants, so you can focus on your work without worrying about reagent quality.

Key Applications in Molecular Biology
This molecular biology-grade KOH is versatile enough for multiple protocols:
DNA/RNA Extraction: Used in lysis buffers to break down cell membranes and release nucleic acids. The high purity prevents degradation of sensitive genetic material during isolation.
pH Adjustment: Essential for calibrating buffers in PCR, electrophoresis, and cell culture media. The pellet form allows for precise titration without clumping.
Protein Studies: Employed in protein solubilization and denaturation steps, particularly in SDS-PAGE sample preparation.
Enzymatic Reactions: Acts as a catalyst in certain biochemical assays where controlled alkalinity is required.
For students learning basic lab techniques, these pellets are ideal for practicing titration curves or studying strong base properties. The uniform size ensures consistent results in educational settings.
Safety and Handling
Potassium hydroxide is a strong base and requires careful handling. Always wear appropriate PPE, including nitrile gloves, safety goggles, and a lab coat. Work in a well-ventilated area or under a fume hood when dissolving pellets, as the process releases heat. Store in a cool, dry place away from acids and moisture to prevent degradation.

Why This Grade Matters
Not all KOH is created equal. Molecular biology applications demand reagents with minimal trace metal contamination. This 85% grade undergoes additional purification steps to remove iron, zinc, and other ions that could interfere with enzymatic reactions or spectroscopic analyses. The result is a product that delivers:
– Lower background noise in sensitive assays
– Longer shelf life due to reduced oxidative impurities
– Batch-to-batch consistency for reproducible results
Compared to industrial-grade KOH, this version is significantly more reliable for research where even minor impurities can skew data. It’s the same quality used in published studies and pharmaceutical development labs.
Storage and Stability
To maintain potency, store the pellets in their original airtight container. KOH is hygroscopic, meaning it absorbs moisture from the air, which can lead to caking and reduced effectiveness. If you notice the pellets becoming sticky or discolored, it’s time to replace your stock. Under proper conditions, this product remains stable for up to 2 years from the manufacture date.
For labs in humid climates, consider using desiccant packs in the storage container to extend shelf life. Always reseal the bag immediately after use to prevent contamination.
FAQs
What is the difference between molecular biology grade and reagent grade KOH?
Molecular biology grade KOH undergoes stricter purification to remove trace metals and nucleases that could interfere with DNA/RNA work. Reagent grade is suitable for general chemistry but may contain impurities that affect sensitive biological assays.
Can I use these pellets for making KOH solutions for electrophoresis?
Yes, these pellets are ideal for preparing Tris-acetate-EDTA (TAE) or Tris-borate-EDTA (TBE) buffers. The high purity ensures no interference with DNA migration during gel electrophoresis.
How do I safely dispose of unused KOH pellets?
Neutralize with a weak acid like acetic acid until pH 7, then dilute with water before disposal according to your institution’s chemical waste guidelines. Never discard untreated KOH in regular trash.
What’s the typical working concentration for KOH in DNA extraction?
Most protocols use 0.1M to 0.5M KOH for cell lysis. For 1M stock solution, dissolve 56.1g of these pellets in 1L of deionized water, then dilute as needed.
Does eqipped offer smaller pack sizes for individual researchers?
Currently, we offer this product in 500g packs, which is cost-effective for most lab needs. For smaller quantities, consider splitting with lab mates or storing properly to maintain freshness.
