Plastic test tubes with caps — practical, reliable tubes for lab and home use Key benefits Secure, capped storage: Each tube includes a tight-fitting cap to reduce leaks and contamination when collecting, storing, or transporting small liquid samples. Versatile for many applications: Designed for a wide range of uses from simple experiments and sample collection to routine tasks in molecular biology and educational projects. Durable and easy to handle: Made from plastic with careful workmanship and a practical, stable design that resists breakage and is comfortable to hold and label. Professional appearance and function: Compact, small tubes that offer a clean, consistent solution for organizing reagents, samples, or test liquids. What it does and how it helps Collects and contains precise small-volume liquids so you can measure, transport, and store samples with confidence. Protects samples from spills and environmental contamination thanks to the included caps. Simplifies workflow by providing uniform, stackable tubes that are easy to sort, label, and store. Important attributes Material: plastic (lightweight and shatter-resistant). Closure: fitted caps for secure sealing. Size: small tubes suitable for handling and storing small liquid volumes (as described). Design: sturdy construction and a practical form factor for routine laboratory and home tasks. Compatibility: suitable for general laboratory workflows and common molecular biology tasks where non-glass tubes are acceptable. Practical use scenarios Laboratory sampling: Collect and temporarily store liquid samples during routine lab experiments or field sampling without the fragility of glass. Molecular biology workflows: Use as convenient containers for small-volume reagents, sample aliquots, or temporary storage during multi-step procedures. Educational and home experiments: Ideal for classroom kits, hobby science projects, or home testing where lightweight, safe tubes with caps are preferred. Why choose these tubes They combine simple, dependable sealing with durable plastic construction and a professional, practical design—making them suitable for both everyday lab work and informal, at-home experiments.
