Heathrow Scientific Reagent Reservoir Chiller 100mL - 120733 | Keeps Below 5°C ~1 Hr, Pack of 2

Larger reagent volumes in 100mL reservoirs present a greater thermal challenge — more liquid mass means longer warm-up times, but also means longer runs and more time for temperature-sensitive reagents to degrade at ambient bench temperature. The Heathrow Scientific Reagent Reservoir Chiller for 100mL Reservoirs solves this with a purpose-engineered polypropylene block that precisely fits the 100mL reservoir format, maintaining reagents below 5°C (41°F) for approximately one hour while the run proceeds at ambient temperature.

Pre-chill in a standard −20°C freezer, load the reservoir, and work without ice bath setup, condensation risk, or cold room dependence. At 6.2 × 9 × 1.7 in, the 100mL chiller is sized to match the wider footprint of the larger reservoir format. Pack of 2 for rotation between consecutive plate runs. Available in Purple, Blue, and Purple & Blue combination.

Features and Benefits

• Custom-Fit for Heathrow Scientific 100mL Reservoirs: Dimensionally matched to the 100mL reservoir format (6.2 × 9 × 1.7 in) — ensuring full-perimeter thermal contact with the reservoir walls for maximum cold transfer and uniform temperature maintenance across the entire reagent volume.

• Below 5°C for ~1 Hour — No Ice or Cold Room: Pre-freeze in a standard −20°C lab freezer and use at ambient bench temperature — eliminates ice bath condensation, spill risk, and cold room protocol requirements for temperature-sensitive 100mL reservoir workflows.

• Polypropylene — Reusable, Chemical Resistant: Withstands repeated freeze-thaw cycles and resists common lab cleaning agents — the chiller is a long-life reusable tool that amortizes to very low cost-per-use across hundreds of plate preparation sessions.

• Pack of 2 for Continuous Operation: Two chillers per pack enables uninterrupted cold-chain pipetting — rotate between active use and refreezing without stopping the workflow between consecutive plate runs.

• Color Options for Reagent-Type Color-Coding: Purple, Blue, and Purple & Blue combination packs allow labs to assign chiller colors to specific reagent categories — preventing mix-ups between enzyme solutions, antibody stocks, and cell reagent reservoirs in multi-assay high-throughput environments.

Laboratory Applications

• High-Volume Enzyme & Antibody Plate Filling: Fill 96- and 384-well plates with enzymes, antibodies, and detection reagents from 100mL reservoirs while keeping the full reagent volume cold — critical for long plate-filling runs where ambient warming degrades activity before the last wells are dispensed.

• Batch PCR Setup from Shared Master Mix: Prepare large batches of PCR master mix in a 100mL reservoir and dispense into multiple plates while keeping the mix cold — ensures consistent enzyme activity and primer stability from the first to the last plate in a multi-plate run.

• Drug Discovery & HTS Compound Dispensing: Maintain compound solutions and DMSO-sensitive reagents at low temperature during high-throughput screening plate preparation — preventing evaporation and degradation of compounds during extended dispensing sessions.

Frequently Asked Questions

What is the difference between the 50/55mL and 100mL chillers?
The 50/55mL chiller (120730/120731/120732) is dimensionally matched to the smaller Heathrow Scientific 50/55mL reservoir format. The 100mL chiller (120733/120734/120735) is wider and longer to match the 100mL reservoir's larger footprint. Using the wrong size chiller will result in poor thermal contact and reduced cold retention performance.

How long does it take to refreeze the chiller for the next run?
In a standard −20°C laboratory freezer, the chiller typically requires 30–60 minutes to return to full cold capacity. With 2 chillers per pack, one can be re-chilling while the other is in active use — enabling continuous back-to-back plate runs.

Can the chiller be used in a −80°C freezer for faster chilling?
The polypropylene construction is compatible with standard −20°C freezer storage. For −80°C applications, consult Heathrow Scientific support to confirm material compatibility at ultra-low temperatures before use.

Are all three color options functionally identical?
Yes — Purple (120733), Blue (120734), and Purple & Blue combination (120735) are identical in construction and cold performance. Color selection supports reagent-type color-coding and workflow organization in multi-assay laboratory environments.

Quality Assurance

Heathrow Scientific Reservoir Chillers are manufactured from polypropylene under rigorous quality standards. The 100mL custom-fit design is dimensionally validated against Heathrow Scientific 100mL reservoir specifications for consistent cold retention performance across repeated freeze-use cycles.
