Product Description
When precision matters in molecular biology, Formamide 99.5% from CDH delivers unmatched purity and performance. This high-grade solvent is a staple in labs conducting PCR, DNA hybridization, and nucleic acid research. Its ultra-low nuclease activity ensures reliable results, making it the preferred choice for researchers and students alike.
Formamide acts as a denaturing agent, lowering the melting temperature of DNA and RNA to facilitate hybridization. Whether you’re running gel electrophoresis or preparing samples for sequencing, this molecular biology-grade formamide maintains consistency across experiments. The 99.5% purity minimizes interference, so you can trust your data every time.
At eqipped, we understand the demands of modern labs. That’s why we source only the highest-quality reagents, including this CDH-certified formamide. Available in convenient 500 ml and 1 lit pack sizes, it’s designed to meet both small-scale and bulk requirements without compromising on quality.

Why Formamide 99.5% is Essential for Your Lab
Molecular biology experiments require solvents that won’t introduce contaminants or degrade samples. Here’s why this formamide stands out:
First, its 99.5% purity ensures minimal background noise in sensitive assays. Unlike technical-grade alternatives, this version is specifically processed to remove nucleases and other impurities that could compromise your results. This makes it ideal for applications like in situ hybridization, where even trace contaminants can lead to false positives.
Second, formamide’s ability to reduce DNA melting temperature by approximately 0.7°C per 1% concentration allows for precise control over hybridization conditions. Researchers often use it to adjust stringency in Southern blots or FISH protocols, ensuring specific binding without off-target interactions.
Finally, its stability at room temperature simplifies storage and handling. While some solvents require refrigeration, this formamide can be stored at 15-25°C, making it practical for everyday lab use. Just remember to keep it tightly sealed to prevent moisture absorption.
Common Applications in Research
From academic labs to biotech startups, Formamide 99.5% plays a critical role in:
PCR Optimization: Used in gradient PCR to fine-tune annealing temperatures for difficult templates.
DNA Sequencing: Helps denature templates during cycle sequencing reactions.
In Situ Hybridization: Enables specific probe binding in tissue sections or cells.
Northern/Southern Blotting: Improves transfer efficiency and reduces non-specific binding.
RNA Structure Studies: Assists in secondary structure analysis by destabilizing hydrogen bonds.
At eqipped, we’ve seen how this versatile reagent becomes indispensable once introduced to a lab’s workflow. Many of our customers who initially bought formamide for a single application soon find themselves using it across multiple protocols.
Handling and Safety Considerations
While formamide is generally safe when handled properly, it’s important to follow standard lab practices. Always wear appropriate PPE, including gloves and goggles, when working with this chemical. Perform experiments in a well-ventilated area or under a fume hood, as prolonged exposure to vapors may cause irritation.
For disposal, follow your institution’s chemical waste protocols. Never pour formamide down the drain. Store the bottle in a cool, dry place away from direct sunlight and incompatible substances like strong oxidizing agents.

Choosing the Right Pack Size
Selecting between the 500 ml and 1 lit options depends on your lab’s usage patterns. The 500 ml bottle is perfect for:
Small research groups running occasional PCR experiments
Teaching labs where students perform limited molecular biology exercises
Startups testing protocols before scaling up
The 1 lit bottle makes more sense for:
High-throughput sequencing facilities
Core labs serving multiple research groups
Established labs with frequent hybridization needs
Remember that formamide has a long shelf life when stored properly, so buying in bulk can be cost-effective for regular users. At eqipped, we offer both sizes to accommodate different research scales and budgets.
Formamide vs. Other Denaturing Agents
While alternatives like urea or DMSO exist, formamide offers unique advantages:
Unlike urea, it doesn’t crystallize at higher concentrations, making it more reliable for long incubations.
Compared to DMSO, it provides better control over hybridization stringency without the strong odor.
Its liquid form at room temperature simplifies handling compared to solid denaturants.
For most molecular biology applications, formamide strikes the perfect balance between effectiveness and ease of use. That’s why it remains the gold standard in labs worldwide.
FAQs
What makes molecular biology grade formamide different from technical grade?
Molecular biology grade formamide undergoes additional purification to remove nucleases, heavy metals, and other contaminants that could interfere with sensitive biological assays. Technical grade may contain impurities that affect PCR efficiency or cause background in hybridization experiments.
Can I use this formamide for RNA work?
Yes, this 99.5% pure formamide is suitable for RNA applications. Its low nuclease activity helps preserve RNA integrity during denaturation and hybridization steps. Many researchers use it for Northern blots and in situ hybridization with RNA probes.
How should I store opened bottles of formamide?
Store opened bottles at 15-25°C in a tightly sealed container. To prevent moisture absorption, you can add molecular sieves to the bottle. Always keep it away from direct sunlight and heat sources. Properly stored, it remains stable for at least 12 months.
What’s the typical working concentration for PCR?
For PCR, formamide is usually used at 1-5% final concentration to optimize annealing temperatures. Start with 2.5% and adjust based on your specific primers and template. Higher concentrations (up to 50%) may be used in some hybridization protocols.
Does eqipped offer bulk discounts on formamide?
Yes, we provide competitive pricing on bulk orders. Contact our customer support team to discuss volume discounts for research institutions or large-scale projects. We also offer special pricing for educational institutions purchasing for teaching labs.
