Purpose and benefits Small, cylindershaped sample bottles designed for secure storage and easy handling of liquid or solid samples and chemical reagents. Compact and lightweight for convenient transport, shortterm storage, and repeated use in laboratory or field settings. Durable glass construction resists chemical interaction and preserves sample integrity over time. Key features Cylinder shape and stable base reduce tipping and make labeling straightforward. Screwin lid with aluminum cover provides a tight seal to minimize evaporation and prevent spills. Professionalgrade glass body is durable, chemically compatible with many reagents, and suitable for longterm use. Compact size and light weight make these mini sample bottles practical for sample collection, storage, and distribution. Why choose this product Reliable sealing and durable glass protect valuable samples and reagents from contamination and leakage. Userfriendly screwin cap allows fast opening and secure closure for frequent access. Small footprint and portability save bench space and simplify transport between sites. Typical applications 1. Laboratory sample handling: collect, transport, and temporarily store small volumes of reagents or specimens during experiments and analyses. 2. Field sampling: lightweight, sealed containers for collecting environmental or onsite chemical samples without risk of spills. 3. Smallbatch reagent storage: hold and dispense small amounts of chemicals or standards where glass compatibility and reliable sealing are required. Materials and performance Glass bottle body for chemical resistance and longterm durability. Aluminum screwin cover engineered for good sealing performance and safe handling. Suitable for repeated use when cleaned and handled according to standard lab practices. Practical notes Ideal when a compact, leakresistant container is needed for smallvolume samples or reagents. Ensure caps are fully tightened to maintain the seal; follow appropriate cleaning and storage procedures for the reagents in use.
