Frequently Asked Questions

Which reagent kit should I start with?
Marquis is the most versatile single reagent and a great starting point. For more thorough results, we recommend using 2–3 different reagent kits together. Our multi-reagent packages come pre-selected with guided flow charts to make this easy.
How many tests do I get per bottle?
Each plastic bottle provides approximately 50–100 tests. Glass bottles hold more reagent and provide approximately 100–200 tests. Only a tiny sample is needed for each test.
How do I read the results?
Every kit includes a 20+ page HD color reaction booklet with documented reactions. Match the color change to the booklet, or use our free app with 1,300+ verified reaction videos for side-by-side comparison. Results are typically visible within 30–60 seconds.
What's the shelf life?
Stored in a cool, dark place, reagents typically last 12+ months. Glass bottles help preserve freshness longer. All reagents come with printed expiration guidance.
Do you ship internationally?
Yes — we've shipped to over 100 countries. All orders ship in plain, discreet packaging with no external branding. Same-day shipping on domestic orders placed before the cutoff time. Free shipping on US orders over $75.
What is a separation kit?
Our Skylab separation kits use thin-layer chromatography (TLC) to physically separate a sample into its individual components. This provides a more detailed analysis than a spot test and is the closest you can get to a professional lab result at home.
