Purpose and key benefit Stainless steel test tube cover designed to protect tube contents, prevent spills and contamination, and provide a safe, easytohandle closure for routine laboratory use. Why you need it Keeps samples secure during handling and storage. Reduces risk of exposure to hazardous or sensitive materials by closing open tubes. Protects hands from sharp edges with a polished, smooth surface. What makes it stand out Simple, practical design with a reasonable structural layout for reliable fit and function. Polished surface finish for user safety and comfortable handling. Constructed from stainless steel for longterm durability and repeated use. Compact and lightweight for convenient storage and transport. Key attributes Function: covers and protects standard lab test tubes during experiments and storage. Compatibility: intended for use with laboratory test tubes (labs tube cover). Material: stainless steel for corrosion resistance and extended service life. Size/weight: compact in size and light in weight for spaceefficient storage and easy handling. Performance: durable, practical, and secure closure that is safe to handle due to polished edges. Typical applications Routine laboratory experiments where tubes must be temporarily closed to avoid contamination. Sample storage and shortdistance transport in the lab to prevent spills and protect contents. Educational and teaching laboratories where safe, repeatable use and easy storage are required. Practical user notes Easy to clean and reuse. Store in a compact tray or drawer to save bench space. Inspect periodically for wear to maintain secure fit and safety.
