For Academic Research Labs
Free Oligo Tools. No Login. No Subscription. No Data Collection.
Scientifically accurate oligonucleotide calculators built for the researchers who actually use them — graduate students, postdocs, and PIs who need quick, reliable answers without navigating vendor paywalls.
Built for Academic Budgets and Workflows
Common Problem
Commercial tools require expensive site licenses
Our Solution
All 13 OligoPool tools are 100% free with no institutional subscription required. No per-user fees, no feature limits.
Common Problem
Vendor calculators collect your sequences
Our Solution
Every calculation runs in your browser. No sequences are transmitted to any server. Verify this in your browser's Network tab.
Common Problem
Tools require registration or slow logins
Our Solution
No account needed. No login. Bookmark the page and start calculating immediately. Optional registration only for saving analysis history.
Common Problem
Limited grant budgets for software
Our Solution
Zero cost. No need to justify software expenses in grant applications. Redirect your budget to reagents and sequencing.
Common Lab Workflows
Step-by-step guides for tasks you do every week.
PCR Primer Design & Validation
Design primers with optimal Tm, GC content, and no secondary structures — the most common task in any molecular biology lab.
Tools You Need
Real-World Scenario
Your supervisor asks you to clone a gene. You need forward and reverse primers with matched Tm (±2°C), no self-dimers, and GC content between 40-60%. Instead of switching between 3 different tools, use our Primer Analyzer to check everything in one step.
Oligo Resuspension & Stock Prep
When your primers arrive from IDT or Eurofins, you need to resuspend them correctly and prepare working stocks.
Tools You Need
Real-World Scenario
You received 25.3 nmol of lyophilized primer. You want a 100 µM stock solution. Our Dilution Calculator tells you to add 253 µL of TE buffer. Then to prepare a 10 µM working stock: take 10 µL stock + 90 µL water.
CRISPR Guide RNA Library QC
Before ordering a CRISPR pool, validate every guide sequence for synthesis compatibility and functional performance.
Tools You Need
Real-World Scenario
You are designing a genome-wide CRISPR knockout screen with 80,000 guides. Batch QC flags 3,200 guides (4%) with problematic GC content or poly-T runs. You redesign those guides before ordering, saving weeks of troubleshooting.
Who This Is For
Graduate Students
Learning primer design for the first time? Our tools include educational content explaining what each parameter means, not just the answer. The FAQ sections below each calculator cover questions you might be too embarrassed to ask your PI.
Postdocs & Research Scientists
Need to design 50 primers for a mutagenesis library before your next lab meeting? Batch processing, keyboard shortcuts, and zero-friction access let you work at full speed without waiting for license checkout or page loads.
Principal Investigators
No need to negotiate software licenses for your lab. Send your lab members this link — they can start using tools immediately. Privacy-first design means no institutional data governance concerns.
Scientific Accuracy
All calculations use peer-reviewed methods from published literature. We don't use proprietary algorithms.
- Tm calculation: SantaLucia (1998) nearest-neighbor unified parameters
- Salt correction: Owczarzy et al. (2008) monovalent and divalent ion corrections
- Extinction coefficients: Nearest-neighbor method with hypochromicity correction
- Secondary structures: Nearest-neighbor thermodynamic parameters for hairpin/dimer ΔG
