Standard 50 mL conical tube racks are either permanently fixed on the bench or awkward to store. The Heathrow Scientific HS24319 Pop-Up Tube Rack solves both problems: 18 dedicated 30mm wells hold 50 mL Falcon-style tubes upright and secure during active use, and the entire rack collapses flat for drawer or cabinet storage in seconds — no tools, no latches, no disassembly.
An alphanumeric identification grid across all 18 positions supports sample tracking without adhesive labels on the rack. Collapsed racks stack flat for efficient bulk storage. Each order includes a Pack of 2 racks in Green.
Features and Benefits
Dedicated 50mL Format - 18 Wells at 30mm: Purpose-built for 50 mL conical tubes — 30mm wells provide a secure, stable fit for standard Falcon®-style tubes without wobbling during pipetting.
Pop-Up Mechanism - Instant Open and Close: Collapses flat in one motion for storage — snaps to full operating height without assembly when needed. Frees bench space between experiments.
Stackable When Collapsed: Flat racks stack neatly for efficient storage of multiple units — useful for labs that keep several racks in rotation across different experiment batches.
Alphanumeric Well Identification: All 18 positions labeled for precise sample tracking and LIMS-compatible tube-to-position documentation.
Pack of 2: Two racks per order for immediate dual-workflow deployment or one active rack with a backup on hand.
Polypropylene Construction: Chemically resistant and durable for daily bench use across research, clinical, and industrial lab environments.

Laboratory Applications
Cell culture media preparation using 50 mL conical tubes for large-volume reagent mixing, aliquoting, and sterile filtration steps

Space-constrained shared labs where dedicated bench space for tube racks is not available between experiments
Environmental and food testing labs running large-volume sample processing protocols in 50 mL conical format
Frequently Asked Questions
Will standard 50 mL Falcon® tubes fit securely?
Yes. The 30mm wells are sized for the standard outer diameter of 50 mL conical centrifuge tubes from all major manufacturers. Tubes seat securely without wobbling during pipetting and sample handling.
Should I get the HS24319 (50mL only) or the HS24320 combo rack?
Choose the HS24319 if your workflow exclusively uses 50 mL tubes and you want maximum 50 mL capacity (18 wells vs 12 in the combo). Choose the HS24320 combo if you regularly run both 15 mL and 50 mL tubes in the same workflow and want to manage both in a single rack.
How compact is the collapsed rack?
Collapsed height is approximately 1.75 in (4.4 cm). Collapsed racks stack flat, making it practical to store 5–10 racks in a single drawer or cabinet shelf.
Is this rack autoclavable?
The HS24319 is not rated for autoclave use. For autoclavable 50 mL tube organization, consider the Heathrow Scientific Snap-Together Conical Tube Rack (HS24306) or the 4-Way Tube Rack series.
Quality Assurance
Heathrow Scientific designs the HS24319 Pop-Up Tube Rack for reliable daily performance with standard 50 mL conical tubes. The polypropylene frame is tested for consistent pop-up spring action and stable 30mm well geometry across all 18 positions.
