50hole stainless steel test tube stand provides organized, tidy bench space by securely holding up to 50 tubes in square holes with a convenient handle for easy relocation. It serves as a reliable Test Tube Stand, Test Tube Organizer, and 50holes Test Tube Stand in one. stainless steel construction offers durability while remaining lightweight, making it easy to carry between work areas or storage locations without compromising stability on the bench. Square holes with a handle design allow secure tube placement and straightforward movement, helping to streamline workflow during setup, experiments, or sample processing. Smooth polished surface with no sharp edges protects hands and instruments, reducing the risk of cuts or damage during handling and transport. Functional for everyday laboratory tasks: keeps tubes organized during routine sample preparation, supports reaction setup and staging, and facilitates safe transport between benches or from storage to workstations. Use scenarios: Routine sample preparation: place multiple tubes in the 50 holes for quick access and efficient workflow. Experiment setup: organize tubes by reagent or time point, then move the stand as a single unit to the work area. Betweenworkflow transport: relocate the stand with all tubes to another bench or cabinet without rearranging individual tubes.
