A dedicated conical tube rack that ships flat, assembles without tools, and holds twice the tube count of most pop-up racks. The Heathrow Scientific HS24306 Snap-Together Conical Tube Rack accommodates 30 standard 15 mL tubes in 17mm wells and 20 standard 50 mL tubes in 28mm wells — all in a single compact footprint that snaps into a rigid ABS frame in seconds.
Unlike polypropylene pop-up racks, the HS24306 uses ABS (acrylonitrile butadiene styrene) — a harder, more dimensionally stable engineering-grade plastic that snaps together with more rigidity and resists deformation in water bath use. Alphanumeric identification across all positions supports sample tracking. Ships flat, stores flat, assembles on demand.
Features and Benefits
Dual-Format: 30 Wells (15mL) + 20 Wells (50mL): High combined capacity for both tube sizes in one rack — 30 positions at 17mm for 15 mL conical tubes and 20 positions at 28mm for 50 mL conical tubes.
ABS Construction - Superior Rigidity: Acrylonitrile butadiene styrene snaps together into a harder, more dimensionally stable frame than polypropylene — maintains well alignment and structural integrity during water bath use and high-volume sample handling.
Flat-Pack Storage and Shipping: Arrives as a flat component set — stores compactly before assembly, assembles into a rigid rack in seconds without tools or fasteners.
Water Bath Stable Design: ABS frame maintains its assembled geometry during submersible water bath incubations — reliable tube positioning throughout temperature-controlled protocols.
Alphanumeric Well Identification: Molded position labels across all 50 wells support precise sample tracking and LIMS-compatible tube-to-position documentation.
Compact 8.1 × 6.7 in Footprint: 50 total tube positions in a near-square bench footprint — efficient use of bench space for labs running parallel 15 mL and 50 mL conical tube workflows.

Laboratory Applications
Cell culture media preparation and reagent management requiring organized simultaneous access to both 15 mL and 50 mL conical tube formats
High-throughput sample processing where maximum combined 15 mL and 50 mL capacity in a single rack reduces bench clutter during batch runs
Water bath protocols requiring a rigid, stable conical tube rack — ABS maintains better dimensional stability in water baths than polypropylene pop-up alternatives
Labs ordering individual rack units for single-station use where pack-of-2 quantities are unnecessary
Frequently Asked Questions
What is the difference between ABS and polypropylene for a lab rack?
ABS is a harder, more rigid engineering plastic that snaps into a more structurally stable assembled form than polypropylene. It resists deformation under water bath conditions better than PP and maintains tighter well alignment after repeated handling. The trade-off is that ABS is generally not autoclave-compatible — if sterilization is required, the Fold & Snap (PP) or GFPP Peg Rack series are better choices.
Is this rack autoclavable?
The HS24306 is made from ABS and is not rated for autoclave use. For autoclavable conical tube organization, see the Heathrow Scientific GFPP Peg Rack (HS24311) or Fold & Snap series.
How does this compare to the HS24320 Pop-Up Combo rack?
The HS24306 offers higher combined capacity (30+20 = 50 total positions vs 21+12 = 33) and a lower per-rack cost, but comes as a single unit versus a pack of 2. It also uses ABS rather than polypropylene, which provides better water bath rigidity. See the comparison table above.
Once assembled, can the rack be taken apart and stored flat?
The snap-together connection is designed for a secure permanent assembly. Unlike the pop-up rack design, this rack is not intended for repeated collapse and re-expansion — it snaps together once for long-term use.
Quality Assurance
Heathrow Scientific manufactures the HS24306 Snap-Together Conical Tube Rack from ABS for superior snap-joint rigidity and dimensional stability in water bath environments. Each rack is tested for secure connector engagement and consistent well alignment across all 50 positions after assembly.
