Heathrow Scientific Reagent Reservoir Chiller 50/55mL - 120730 | Keeps Below 5°C ~1 Hr, Pack of 2

Temperature-sensitive reagents loaded into a standard reservoir begin warming the moment they leave the cold storage — by the time a long multichannel pipetting run is complete, enzyme activity, antibody binding, and cell viability assay reagents may be compromised. The Heathrow Scientific Reagent Reservoir Chiller for 50/55mL Reservoirs holds reagents below 5°C (41°F) for approximately one hour without requiring ice, a cold room, or any additional equipment. The custom-fit polypropylene chiller is engineered specifically for Heathrow Scientific 50/55mL reagent reservoirs, ensuring a snug thermal contact that maximizes cold retention throughout the pipetting session.

Pre-chill the chiller in a freezer, insert the reservoir, and work at bench temperature without reagent degradation concerns. At 6.1 × 2.9 × 1.7 in and under 0.7 lb, the chiller adds minimal footprint to the workstation. Each pack contains 2 chillers. Available in Purple, Blue, and a Purple & Blue combination pack.

Features and Benefits

• Maintains Reagents Below 5°C for ~1 Hour: Pre-chilled in a standard freezer, the chiller keeps reagents cold throughout extended multichannel pipetting runs — preventing enzyme deactivation, antibody degradation, and cell reagent compromise during temperature-sensitive assay workflows.

• Custom-Fit for Heathrow Scientific 50/55mL Reservoirs: Engineered to precisely fit Heathrow Scientific 50/55mL reagent reservoir dimensions — ensuring full thermal contact with the reservoir walls for maximum cold transfer efficiency, unlike generic chillers with loose fits that leave air gaps.

• No Ice or Cold Room Required: Freeze the chiller block, insert the reservoir, and work at ambient bench temperature — eliminates the condensation, spill risk, and setup time associated with ice bath reservoir cooling methods.

• Polypropylene Construction — Chemical Resistant & Reusable: Durable PP resists common laboratory reagents and cleaning solutions — the chiller is reusable across many freeze-use-refreeze cycles, making it a low cost-per-use cold-chain tool for high-throughput labs.

• Pack of 2 — One in Use, One Pre-Chilling: Two chillers per pack enables a rotation strategy — one chiller in active use while the second re-chills in the freezer, allowing continuous cold pipetting across back-to-back plates without waiting for the chiller to refreeze.

Specifications

Laboratory Applications

• Enzyme & Antibody Dispensing: Keep restriction enzymes, polymerases, kinases, and antibody solutions cold during multichannel dispensing — prevents activity loss and aggregate formation that occurs when these reagents warm above 5°C during extended plate-filling runs.

• PCR Master Mix & Primer Dispensing: Maintain PCR components at low temperature during high-throughput plate setup — critical for hot-start polymerases and temperature-sensitive master mixes where premature activation reduces amplification efficiency.

• Cell Viability & Cytotoxicity Reagents: Dispense cell-based assay detection reagents, substrates, and lysis buffers cold to prevent premature substrate activation and background signal development before microplate reading.

• Rotation Strategy for Back-to-Back Plate Runs: With 2 chillers per pack, one stays in active use while the other re-chills — enabling continuous high-throughput plate preparation without cold-chain interruption between consecutive runs.

Frequently Asked Questions

How do I prepare the Reservoir Chiller before use?
Place the chiller in a standard laboratory freezer (−20°C) for at least 30 minutes before use. Remove, insert the 50/55mL reagent reservoir, and the chiller will maintain reagent temperature below 5°C for approximately one hour under typical ambient lab conditions (20–25°C).

Is the Reservoir Chiller compatible with non-Heathrow reservoirs?
The chiller is engineered for a custom fit with Heathrow Scientific 50/55mL reagent reservoirs. Fit and thermal performance with reservoirs from other manufacturers is not guaranteed due to dimensional differences between brands.

What is the difference between the Purple, Blue, and Purple & Blue packs?
All three are functionally identical. Purple (120730) and Blue (120731) packs each contain 2 chillers of that color. The Purple & Blue pack (120732) contains one of each — useful for labs that color-code reservoirs by reagent type and want matched chiller/reservoir color pairing.

Is there a chiller for the 100mL reservoir?
Yes — Heathrow Scientific also offers the Reagent Reservoir Chiller for 100mL reservoirs (120733/120734/120735), available separately on LabSupplies.com.
