The wireless open-bottom design that makes full-size tube racks ideal for bottom-read instrument access applies equally to microcentrifuge tube workflows. Globe Scientific's Wireless MicroTube Racks hold 1.5mL and 2.0mL microcentrifuge tubes on reinforced nylon pegs with no bottom tray, leaving tube bottoms accessible for reading, scanning, or bottom illumination without removing tubes from the rack. Alphanumeric position markings on the rack allow individual tube positions to be recorded and referenced in lab notebooks or LIMS systems without physical labeling of the rack itself.
Available in 96-Place (456340, $26.70/EA) and 24-Place (456345, $17.60/EA), both in four colors — Blue, Red, White, Yellow. Single-piece nylon construction provides rigidity without joints or assembly, and molded handles on each end allow the loaded rack to be carried safely. Both sizes are autoclavable for decontamination between sample sets.
Features and Benefits
Open-Bottom Wireless Peg Design: No bottom tray — tube bottoms are fully exposed for bottom-illuminated readers, scanners, and cameras accessing tube bases without removing tubes from the rack during analysis or documentation.
Alphanumeric Position Markings: Each tube position is labeled with an alphanumeric identifier (A1, A2... grid) molded into the rack, allowing specific sample positions to be recorded and retrieved by position reference without additional labels on the rack.
Two Sizes for Different Workflows: 96-Place (456340, $26.70) for large batch processing of full sample sets; 24-Place (456345, $17.60) for small batches, priority subsets, and situations where a smaller rack footprint is needed. Both in 4 colors.
Single-Piece Reinforced Nylon Construction: One-piece nylon body with no joints or assembly — no snapping together, no alignment issues, no pieces to lose. Reinforced nylon provides chemical resistance and dimensional rigidity under full tube load.
Molded Handles for Safe Transport: End handles allow the fully loaded rack to be carried without touching individual tubes — important in molecular biology workflows where cross-contamination at the tube body is a concern.

Laboratory Applications
Molecular biology and genomics labs using bottom-read plate readers or imaging systems to read fluorescence or colorimetric results from microcentrifuge tubes without removing them from the rack during the read step
Sample set tracking workflows where alphanumeric grid positions allow individual tube positions to be recorded by grid coordinates in LIMS or lab notebooks, enabling unambiguous position-based sample retrieval without additional rack labeling
High-throughput processing and storage of 1.5mL and 2.0mL microcentrifuge tube sample sets in 96-position format, compatible with 96-well plate processing workflows where rack position count matches plate format
Frequently Asked Questions
Do these racks fit 0.5mL microcentrifuge tubes?
No — the 456340 and 456345 are designed for 1.5mL and 2.0mL microcentrifuge tubes only. For 0.5mL tube storage and processing, see the Globe Scientific stackable PC microcentrifuge racks (456330 series).
96-Place vs 24-Place — which size is better?
96-Place (456340) provides full-plate-format capacity for large batch runs and matches 96-well plate sample counts common in molecular biology. 24-Place (456345) is better for smaller batches, priority queues, and compact bench spaces. Many labs use a mix: 96-place for primary batch processing, 24-place for add-ons, controls, and repeats handled separately.
