Measuring bottles with attached tubes Smooth inner walls reduce liquid adsorption and carryover, helping preserve sample integrity and ensuring more reliable test results. Clear, consistent dispensing through the integrated tube for accurate measurement and transfer of small volumes. Plastic sample tubes Precisely molded, durable plastic with a practical, well-considered structure for consistent handling. Ergonomic design for comfortable use during routine sample processing and transport. Suitable as general-purpose sample tubes. Plastic reagent tubes with screw caps Secure screw-cap closure provides reliable, leak-resistant sealing for reagents and samples. Soft, easy-to-open caps allow quick access without excessive force, while maintaining a tight seal during storage or transport. Small storage tubes with lids Compact tubes with caps designed for convenient storage of small-volume samples. Widely used across molecular biology, chemistry and biochemistry applications for short-term storage, reagent aliquots and sample organization. Key attributes and performance Material: durable plastic construction for lightweight, practical lab use. Function: sample collection, reagent containment, dispensing and short-term storage. Compatibility: designed for routine laboratory workflows in molecular biology, chemistry and biochemistry environments. Performance: low-adsorption interior (measuring bottles), secure leak-proof sealing (screw caps), and user-friendly cap design. Practical use scenarios 1) Field sampling: collect, seal and transport liquid samples with reduced adsorption and secure screw-cap protection. 2) Lab aliquoting: dispense reagents or aliquot samples into small tubes for assays, storage, or downstream processing. 3) Molecular biology workflows: store small-volume DNA/RNA or buffer aliquots and handle routine sample transfers with minimal carryover. Reliable, professional-grade plastic tubes and bottles designed for consistent handling, secure closure and reduced sample loss across routine lab applications.
