Test Tube Stand
Product Code : SCL-CLE-11948
The StemAids Test Tube Stand (or Test Tube Rack) is an essential laboratory organizational tool designed to support multiple test tubes in a secure, vertical position. It serves a dual purpose: providing a stable platform for reactions occurring simultaneously and offering a safe drainage and storage solution for cleaned glassware. Manufactured in various materials including high-density polyethylene (HDPE), wood, and stainless steel, it is engineered to resist chemical spills and maintain stability under the weight of liquid-filled tubes.

Key Pedagogical & Laboratory Outcomes
- Organizational Interface: Facilitates student understanding of Comparative Analysis. By holding multiple tubes side-by-side, learners can identify subtle color changes or precipitate heights across a series of reactions.
- Storage Application: Enables efficient Glassware Maintenance; models with drying pegs allow learners to apply proper post-experiment protocols by inverting cleaned tubes for streak-free drying.
- Safety Analysis: Supports the analysis of "Spill Prevention"; students evaluate the importance of a stable base in preventing the accidental tipping of hazardous reagents, a common risk in crowded laboratory environments.
- Workflow Evaluation: Provides a platform for evaluating serial dilutions and large-scale sampling; the grid-style numbering on larger racks helps students track samples without labeling errors.
Material Selection Guide
- Polypropylene (Plastic): The most versatile option. It is lightweight, color-coded for organization, and can be placed in an autoclave for sterilization in biology labs.
- Polished Wood: A traditional choice for chemistry labs. It offers a heavy, stable base and is aesthetically suited for dry-reagent stations, though less resistant to prolonged moisture.
- Stainless Steel: The premium choice for high-temperature or extreme chemical environments. It is virtually indestructible and ideal for use in water baths.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade, space-saving packaging. Many plastic models are shipped "knock-down" (flat-packed) and can be easily snapped together at the destination to reduce shipping volume and costs.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and Material Data Sheets.
- Durability: Our HDPE stands are treated with UV stabilizers to prevent the plastic from becoming brittle over time when exposed to sunlight or laboratory lighting.
Direct OEM Sourcing Advantages
Procuring StemAids Test Tube Stands directly ensures vertical manufacturing control:
- Precision Hole Sizing: Direct oversight ensures holes are sized exactly to international test tube standards, preventing "wobble" or tubes getting stuck.
- Vibration Resistance: We design our racks with a reinforced base to ensure they remain steady even when placed on a vibrating laboratory shaker or near a centrifuge.
- Direct Factory Inventory: Guaranteed availability of specialized racks, including Slant Racks for agar media and Micro-tube Racks for PCR work.
- Quality Assurance: Every batch is "buoyancy tested" (for plastic models) to ensure they do not float or tip when used in a water bath.
