The 20-position format fills the gap between the compact 12-place tube racks suited to individual specimen sets and the 80-100-place racks used for full plate-format batch processing. Globe Scientific's 456320 Reinforced PP 20-Place Microcentrifuge Rack holds 1.5mL and 2.0mL tubes with rubber feet that grip the bench surface during pipetting, and numeric position markings that allow individual tube positions to be recorded by number without physical labels on the rack. The combination of anti-slide feet, position identification, and reinforced PP construction makes this a practical daily-use rack for small-to-medium sample sets.
Available in Blue (456320B), Red (456320R), and White (456320W) at $32.50/EA, autoclavable, made in India.
Features and Benefits
Rubber Feet Prevent Bench Sliding: Molded rubber feet grip bench surfaces during pipetting and tube manipulation — eliminates the rack-drift problem that affects smooth-bottom racks on polished or wet bench surfaces.
Numeric Position Markings: All 20 positions are numbered, enabling individual tube tracking by position number in lab records without requiring physical labels on the rack for each run.
20-Place for Small-to-Medium Sample Sets: 20 positions covers 6 triplicate samples plus 2 controls, a standard strip-plate ELISA sample set, or a typical bench PCR reaction panel — sized for workflows where 24-well plate-format racks are slightly oversized.
Reinforced PP, Autoclavable: RPP provides greater rigidity than standard PP under full tube load. Autoclave-compatible for decontamination between sample sets.
3 Colors at Same Price: Blue, Red, White at $32.50/EA — color coding by experiment, sample type, or protocol step.

Laboratory Applications
PCR setup and small-panel molecular biology using 20 or fewer 1.5mL/2.0mL tubes per run, where rubber feet provide bench stability during rapid tube manipulation and numeric markings support position-level sample tracking
Manual ELISA and immunoassay protocols where 20 positions covers a standard sample set with controls in a compact rack compatible with benchtop incubators
Research workflows requiring individual tube position documentation — numeric position markings enable position-by-number traceability without rack relabeling between experimental runs
Frequently Asked Questions
Does this fit 0.5mL tubes?
No — the 456320 is for 1.5mL and 2.0mL tubes only. For 0.5mL tube racks see the Globe Scientific stackable PC series (456330).
What is the difference between the 20-place (456320) and the 128-place snap-together (456315)?
The 456320 is a simple upright rack for small sample sets, with rubber feet and numeric markings. The 456315 is a flat-pack snap-together 128-place rack for large batch processing. Both are RPP and autoclavable.
