Durable lab tubes and centrifuge tubes designed for reliable sample handling in the laboratory and beyond. Suitable for a range of applications including standard laboratory tests, sample collection, food coloring experiments, and craft use. Key features Test tubes with lids Plastic material with ultra transparency for easy visual observation during procedures. Clear lid design allows quick inspection without removing the cap. Sturdy and portable design Small, compact size that resists deformation. Lightweight and easy to carry for inlab or field use. Caps for leak prevention and clean transfers Caps help prevent sample leakage and contamination. Smooth, flat inner surface reduces residual solution during handling and transfer. General versatility Suitable as standard lab tubes and as centrifuge tubes for compatible workflows. Fits common laboratory handling practices and observing liquid contents clearly. Typical attributes Function: storage, observation, transfer, and testing of liquids and samples Compatibility: suitable for standard laboratory workflows; includes tubes with lids and caps to prevent leakage Size: small and portable for easy handling Material: plastic; transparency for visibility Performance: durable, with leakproof caps and smooth inner surfaces to minimize residual liquid 23 practical use scenarios Routine laboratory testing and sample preparation Use for preparing, storing, and observing smallvolume samples during assays and experiments. Food coloring, education, and craft applications Ideal for colorm development, demonstrations, and simple crafts that require clear visibility of contents. Field sampling and transport Lightweight, portable tubes with secure caps are suitable for collecting and transporting small samples without leakage.
