ConductScience Tube Racks for 15/50mL Conical Tubes (Pack of 20)
$25.00 per unit | 20 units per pack Bulk pricing: Pack of 20 at $500.00 ($25.00 per unit)
ConductScience Tube Racks for 15/50mL Conical Tubes provide stable, organized storage for standard laboratory centrifuge tubes during sample processing, storage, and transport. Constructed from autoclavable polypropylene, these 50-well racks accommodate both 15mL and 50mL conical tubes commonly used in molecular biology, cell culture, and analytical chemistry workflows.
The detachable and stackable design enables flexible laboratory organization while maintaining tube accessibility during multi-step protocols. Autoclave compatibility allows for sterile technique maintenance in cell culture and molecular biology applications requiring contamination control.
How It Works
The tube rack utilizes a precision-molded polypropylene matrix with 50 individual wells engineered to securely hold standard 15mL and 50mL conical centrifuge tubes. Each well features tapered geometry that accommodates the conical tube profile while providing lateral stability during handling and transport.
The modular design incorporates interlocking features that enable vertical stacking for space-efficient storage while maintaining individual rack accessibility. Detachable construction allows separation of rack components for thorough cleaning and sterilization via autoclave processing at standard laboratory sterilization temperatures.

Comparison Guide
| Feature | This Product | Typical Alternative | Advantage |
|---|---|---|---|
| Well Capacity | 50 wells for tube organization | Entry-level racks often offer 24-32 wells | Higher capacity reduces rack count needed for batch processing workflows |
| Tube Size Compatibility | Accommodates both 15mL and 50mL conical tubes | Many racks are sized for single tube volume | Reduces inventory requirements when protocols use mixed tube sizes |
| Modular Design | Detachable and stackable components | Fixed construction limits cleaning access | Enables complete sterilization and flexible storage configuration |
| Material Construction | Autoclavable polypropylene | Some budget options use non-autoclavable materials | Supports sterile technique requirements in cell culture and molecular biology |
This rack provides higher well capacity with dual tube size compatibility and modular design features. The autoclavable construction and stackable architecture support both sterile technique requirements and space-efficient laboratory organization.
Practical Tips
Disassemble detachable components before autoclave sterilization to ensure steam penetration to all surfaces.
Why: Complete sterilization requires steam access to component interfaces and internal surfaces.
Load tubes systematically using a consistent pattern to reduce sample mix-ups during multi-step protocols.
Why: Organized loading patterns minimize pipetting errors and improve workflow efficiency.
Ensure racks are completely dry before stacking to prevent slipping during handling.
Why: Moisture between stacked racks creates instability that can cause tube spillage.
If tubes become difficult to remove, check for residue buildup in wells and clean thoroughly.
Why: Sample residues can create binding that makes tube removal difficult and increases breakage risk.
Consider color-coding or labeling racks when processing multiple sample sets simultaneously.
Why: Visual identification reduces cross-contamination risk and improves sample tracking accuracy.
Inspect wells periodically for stress cracks that could compromise tube stability.
Why: Damaged wells may not securely hold tubes during handling or centrifugation procedures.

Compliance
What is the maximum autoclave temperature rating for these racks?
Consult product datasheet for specific temperature limits. Standard polypropylene laboratory racks typically withstand 121°C autoclave cycles.
Do the wells accommodate tubes from different manufacturers?
The wells are designed for standard 15mL and 50mL conical tube dimensions. Most major manufacturers follow similar specifications, but verify tube diameter compatibility for specific brands.
How many racks can be safely stacked without compromising stability?
Consult product specifications for maximum stacking height. Consider tube contents and handling requirements when determining optimal stack configuration.
Are the racks compatible with centrifuge tube caps of various heights?
The well depth accommodates standard conical tubes with typical cap configurations. Verify clearance for specialized caps or extended tube formats.
What cleaning agents are compatible with the polypropylene construction?
Most laboratory detergents, alcohols, and dilute bleach solutions are compatible. Avoid strong organic solvents that may cause stress cracking.
Can the racks be used in freezer storage applications?
Consult product datasheet for temperature range specifications. Consider thermal expansion effects when using racks across temperature extremes.
