Purpose and benefit A practical test tube clamp and iron stand set designed to support routine laboratory work. Provides stable, hands-free support for test tubes, rings and other common attachments so you can focus on the experiment rather than holding equipment. Improves workflow by keeping samples secure and accessible, reducing spills and interruptions during heating, mixing or observation. Key features Function: securely holds test tubes, rings and lab mounting clamps for a variety of experimental setups. Construction: iron stand for stable base and metal clamp components built for reliable support and repeatable positioning. Compatibility: works with common test tube sizes and standard ring clamps, making it suitable for general chemistry, biology and teaching labs. Ease of use: simple assembly, straightforward clamp adjustment and quick attachment/detachment of accessories. Maintenance: easy to clean and maintain; robust materials tolerate routine lab cleaning and handling. What makes it useful Stability and reliability reduce accidental tipping or movement during heating or titration. Versatility lets you mount test tubes, hold condensers or secure glassware with rings and clamps, minimizing the need for extra hands. Durable iron construction provides a steady base for repeated use in busy lab environments. Typical applications Heating and boiling small samples over a Bunsen burner while keeping the tube at a safe distance from the flame. Setting up titrations or reagent additions where a fixed, level test tube position improves accuracy. Classroom demonstrations and routine sample handling where easy assembly, durability and clear visibility are important. Practical notes Intended as a general-purpose lab consumable for experimental procedures, sample heating, mounting and holding glassware. Store dry and wipe clean after use to prolong service life.
