The Test Tube Stand (Plastic) provided by IBEX SCIENCES is a fundamental piece of laboratory equipment designed to safely hold, organize, and dry test tubes during clinical procedures, chemical assays, and educational experiments. [1]
Constructed from high-quality polymers, these racks are engineered to withstand the demanding conditions of modern laboratory environments. [1]
Key Features and Material Properties
- Chemical Resilience: Manufactured from durable plastics like polypropylene (PP) or high-density polyethylene (HDPE). This ensures the stand is highly resistant to chemical corrosion, making it safe from accidental spills of acids, bases, and common staining reagents (such as H&E or Diff-Quick solutions). [1]
- Autoclavable and Heat Stable: Most plastic variants from IBEX SCIENCES can be repeatedly autoclaved (typically up to 121°C) for sterilization, making them ideal for sterile microbiology setups or cell culture hoods. [1]
- Ergonomic and Space-Saving Designs:
- Detachable/Collapsible Options: Many models feature a 3-tier snap-together design that can be easily disassembled for flat storage when not in use.
- Molded Grids: Equipped with alphanumeric indexing (rows labeled with letters/numbers) for quick sample tracking and to minimize pipetting errors. [1]
- Dual-Functionality: Often features drying pins or pegs on one side, allowing tubes to be inverted and air-dried cleanly after being washed.
Common Layout Configurations
Depending on your laboratory throughput, these plastic racks are available in several physical formats:
- Multi-Well Formats: Commonly configured in grids such as 24-well, 50-well, 60-well, or 90-well setups.
- Multi-Diameter Racks: Multi-functional, stepped, or rotatable racks that feature different hole sizes on opposing sides to accommodate varying tube diameters simultaneously (e.g., matching standard 10mm, 13mm, 16mm, or 20mm tubes, as well as 15mL and 50mL conical centrifuge tubes). [1]
Care and Maintenance
- Cleaning: Wash with mild laboratory detergents and rinse with water. Avoid using highly abrasive scrubbing pads to prevent scratching the plastic surface. [1, 2, 3, 4]
- Storage: While UV-stabilized plastic is often used, prolonged storage away from direct sunlight when not in use will prevent the polymer from becoming brittle over time.
