ConductScience PCR Tube Racks, 96-Well, Fluorescent (Pack of 25)
$20.00 per unit | 25 units per pack Bulk pricing: Pack of 25 at $500.00 ($20.00 per unit)
The ConductScience PCR Tube Racks provide organized storage and handling for 0.2mL PCR tubes and strips in standard 96-well format. Manufactured from autoclavable polypropylene (PP), these racks withstand repeated sterilization cycles while maintaining dimensional stability. The fluorescent coloring enhances sample visibility and enables color-coding of different experimental conditions or sample types during PCR workflows.
The 96-well configuration accommodates individual PCR tubes or 8-well strips, facilitating high-throughput molecular biology applications. The polypropylene construction ensures chemical compatibility with standard PCR reagents and allows steam sterilization at 121°C. These racks are essential for maintaining sample organization during thermal cycling, storage, and downstream analysis procedures.
How It Works
PCR tube racks function as organizational matrices that maintain precise spatial arrangement of reaction vessels during polymerase chain reaction workflows. The 96-well format corresponds to standard microplate dimensions (8 rows × 12 columns), ensuring compatibility with automated liquid handling systems, thermal cyclers, and plate readers. Each well position accommodates 0.2mL PCR tubes or strips with standardized external dimensions.
The polypropylene construction provides thermal stability across the temperature range encountered in PCR protocols (-80°C to +121°C). The material's low thermal conductivity minimizes heat transfer between adjacent wells, reducing the risk of thermal cross-talk during cycling. The fluorescent coloring incorporates UV-stable pigments that maintain color integrity under laboratory lighting while providing visual contrast for sample identification.
Autoclave compatibility allows steam sterilization at 121°C for 15-20 minutes, eliminating contaminating nucleic acids and proteins. The rack geometry maintains tube positioning during sterilization cycles, and the polypropylene material returns to original dimensions upon cooling, preserving well alignment for subsequent use.

Comparison Guide
| Feature | This Product | Typical Alternative | Advantage |
|---|---|---|---|
| Material Construction | Autoclavable polypropylene with fluorescent coloring | Standard plastics often lack autoclave compatibility or use clear/white materials | Enables repeated sterilization while maintaining sample visibility through color contrast. |
| Tube Compatibility | Accommodates both 0.2mL tubes and strips | Many racks are designed for tubes only or strips only | Provides flexibility to use different tube formats within the same experimental setup. |
| Format Standard | 96-well microplate format | Custom formats vary by manufacturer | Ensures compatibility with standard automated laboratory equipment and thermal cyclers. |
| Temperature Range | Stable from -80°C to +121°C | Limited temperature ranges in basic models | Supports complete PCR workflow from frozen storage through autoclave sterilization. |
These racks combine autoclave-compatible polypropylene construction with fluorescent coloring for enhanced sample organization. The dual compatibility with tubes and strips, along with standard 96-well formatting, provides versatility for different PCR workflows while maintaining compatibility with automated systems.
Practical Tips
Load tubes completely into wells to ensure proper heat transfer during thermal cycling and prevent tube ejection.
Why: Incomplete seating can cause uneven heating and potential sample loss during temperature cycling.
Inspect racks regularly for stress cracks around well openings, especially after repeated autoclave cycles.
Why: Thermal stress can weaken the material over time, potentially affecting tube retention.
Verify tube fit with your specific PCR tubes before large experiments, as tube dimensions can vary between manufacturers.
Why: Proper fit ensures consistent thermal contact and prevents tubes from falling out during handling.
Use the fluorescent coloring systematically to distinguish experimental conditions rather than random organization.
Why: Consistent color-coding reduces sample mix-ups and improves experimental reproducibility.
Allow racks to cool completely after autoclaving before handling to prevent burns and thermal shock to tubes.
Why: Hot polypropylene can cause burns and rapid cooling may crack the material.
If tubes become difficult to remove, check for thermal expansion effects and allow rack to reach room temperature.
Why: Temperature differences can cause tight fits that resolve when thermal equilibrium is reached.

Background reading relevant to this product:
What PCR tube formats are compatible with these racks?
The racks accommodate 0.2mL PCR tubes and strips in standard 96-well format. Both individual tubes and 8-well strips fit properly when fully seated in the wells.
Can these racks withstand autoclave sterilization?
Yes, the polypropylene construction allows steam sterilization at 121°C for 15-20 minutes. The material maintains dimensional stability through repeated autoclave cycles.
Are the racks compatible with automated systems?
The 96-well format follows standard microplate dimensions, ensuring compatibility with automated liquid handlers, thermal cyclers, and plate readers that accept SBS-format plates.
What chemicals are compatible with the polypropylene material?
Polypropylene resists most PCR reagents, organic solvents, and laboratory chemicals. Avoid prolonged exposure to strong oxidizing agents or temperatures above 130°C.
How should I clean these racks between uses?
Wash with mild detergent and distilled water, then rinse thoroughly. For sterile applications, autoclave at 121°C. Avoid abrasive cleaners that could scratch the surface.
What is the temperature range for these racks?
The polypropylene construction remains stable from -80°C storage to +121°C sterilization. This covers typical PCR workflow temperatures including freezer storage and autoclave sterilization.
Can I use these racks for long-term sample storage?
Yes, the chemical-resistant polypropylene is suitable for long-term storage at freezer temperatures. The fluorescent coloring helps maintain sample identification over extended storage periods.
