Heathrow Scientific HDPE Coated Wire Tube Rack 20-25mm - Autoclavable, -40°C

Wire tube racks hold tubes securely while exposing the maximum surface area for visibility and access — no solid walls to obscure sample labels, no deep channels that trap condensation. The Heathrow Scientific HDPE Coated Wire Tube Rack takes this format and adds chemical resistance and temperature range: the HDPE (high-density polyethylene) coating resists the acids, solvents, and disinfectants common in laboratory environments, and the rack remains functional from -40°C through autoclave temperature.

Available in two formats: the compact 2×6 (12 wells, SKU 120085) for bench work where footprint is limited, and the 5×10 (50 wells, SKU 120086) for high-throughput sample handling and processing. Both accommodate 20–25 mm diameter tubes — covering bijou bottles, 50 mL conicals, universal sample vials, and other medium-to-large diameter laboratory containers.

Features and Benefits

• HDPE Coated Wire Construction: High-density polyethylene coating over the wire frame provides chemical resistance against acids, bases, alcohols, and common laboratory solvents — extends rack service life beyond uncoated wire racks in active use environments.

• -40°C Low Temperature Rating: Maintains structural integrity and coating adhesion down to -40°C — suitable for cold room use, freezer sample staging, and cryogenic workflow pre-staging steps where samples are handled at low temperatures.

• Autoclavable: HDPE coating and wire substrate survive standard autoclave cycles — sterilize for use in sterile processing environments without rack replacement.

• 20–25 mm Well Diameter: Fits the common 50 mL conical tube OD (~28 mm at rim, fits loosely), bijou bottles, and most universal vials in the 20–25 mm range — check your tube OD before ordering if fit is critical.

• Open Wire Design: Maximum sample label visibility from all angles — labels, cap colors, and tube contents remain visible without lifting tubes from the rack.

• Two Format Options: 2×6 (120085) for compact bench use; 5×10 (120086) for high-throughput processing when 50-position capacity is needed.

Specifications

Laboratory Applications

• Chemical processing workflows where rack chemical resistance is required for routine acid or solvent wipe-down without rack degradation

• Cold room and refrigerated sample handling where -40°C rating maintains rack performance in chilled storage environments

• High-throughput sample sorting with the 5×10 format (120086) — 50 positions in a single rack footprint for processing large sample batches

• Bijou bottle and universal vial handling in microbiology, environmental sampling, and quality control labs

Frequently Asked Questions

What tubes fit these racks?
Wells accept 20–25 mm outer diameter tubes — this covers most 50 mL conical tubes (outer diameter ~28 mm at the widest point but ~23–24 mm at the body where they rest in the well), standard bijou bottles (20 mm dia.), and universal vials in the 20–25 mm range. Measure your tube outer diameter at the point where it will rest in the well before ordering.

Can I use these in a biosafety cabinet?
Yes — open wire design and compact footprint make these suitable for BSC use. The 2×6 format (120085) is particularly practical for BSC bench space. Both sizes autoclave for sterile BSC applications.

What is the difference between 120085 and 120086?
120085 is a 2×6 format (12 wells, 6.9 × 2.7 in footprint) — compact, designed for bench work with a smaller number of tubes. 120086 is a 5×10 format (50 wells, 11.5 × 6.1 in footprint) for high-throughput use or shared racks holding larger sample sets.

Quality Assurance

Heathrow Scientific HDPE Coated Wire Tube Racks are manufactured with a continuous HDPE coating applied over the full wire surface for chemical resistance and structural durability. Low temperature performance is verified to -40°C. Autoclave compatibility is confirmed for standard 121°C steam cycles.
