Every pipetting error that introduces contamination, wastes reagent, or forces a re-run has a cost. The Heathrow Scientific 5mL Polystyrene Reagent Reservoir is built to prevent the most common failure points in multichannel pipetting: reservoir collapse under pipetting pressure, stacked reservoirs that stick together mid-run, and reagent exhaustion that goes unnoticed until after a plate is spoiled. Crush-resistant corner turrets maintain basin shape under the downward force of a fully loaded 8- or 12-channel pipette. Anti-stacking tabs separate nested reservoirs instantly. Printed graduation marks show remaining volume at a glance.
Every lot is certified DNase-free, RNase-free, and Pyrogen-free — protecting RNA/DNA integrity and preventing endotoxin artifacts in cell-based assays. Available as individually sterile-wrapped (single wrap) in a pack of 50. Sterile variants carry a 4-year sterility expiration date.
Features and Benefits
Certified DNase, RNase, and Pyrogen Free: Every lot is certified free of nucleases and pyrogens — preventing RNA/DNA degradation and endotoxin contamination of sensitive molecular biology and cell-based assays during pipetting.
Crush-Resistant Corner Turrets: Reinforced corner "turret" structures prevent reservoir collapse under the downward pressure applied during multichannel pipetting — maintaining basin shape and reagent depth throughout the pipetting session.
Anti-Stacking Tabs for Easy Separation: Molded tabs prevent nested reservoirs from sticking together — critical in high-throughput environments where fumbling with stuck reservoirs wastes time and risks reagent contamination.
Printed Graduations for Volume Tracking: Clearly printed graduation marks allow operators to monitor remaining reagent volume at a glance — reducing mid-run reagent exhaustion events during plate-filling protocols.
Multiple Packaging Formats — Sterile and Non-Sterile: Available individually sterile-wrapped (single wrap), in groups of 5 (5-wrap), and bulk-wrapped — matching packaging format to protocol sterility requirements and throughput volume without paying for unnecessary individual wrapping on non-sterile applications.

Laboratory Applications
Multichannel Pipetting & Plate Filling: The primary use case — load reagent into the reservoir and dispense simultaneously across an entire row of a 96-well, 384-well, or deep-well plate using an 8- or 12-channel pipette.
ELISA & Immunoassay Plate Preparation: Dispense antibodies, conjugates, substrates, and wash buffers into microplates — the DNase/RNase-free certification prevents signal artifacts from nuclease contamination in antibody-based assays.
PCR & qPCR Master Mix Dispensing: Prepare and aliquot PCR master mixes, primers, and enzyme solutions into strip tubes and plates using multichannel pipettes — sterile single-wrap format maintains aseptic conditions for amplification-sensitive workflows.
Cell-Based Assay Reagent Dispensing: Distribute cell culture media, growth factors, assay reagents, and staining solutions into microplates for high-throughput cell viability, cytotoxicity, and proliferation assays.
Frequently Asked Questions
What is the difference between single wrap, 5-wrap, and bulk wrap packaging?
Single wrap means each reservoir is individually sterile-packaged — highest sterility assurance, ideal for critical molecular biology and cell culture applications. 5-wrap packs 5 reservoirs per sterile bag — good balance of sterility and convenience for moderate-throughput use. Bulk wrap contains 100 reservoirs in a single bag — most economical, for non-sterile applications or workflows where reservoirs are used sequentially from a single opened bag within a short period.
Are these reservoirs compatible with all multichannel pipettes?
Yes. The 5mL polystyrene reservoir basin dimensions are compatible with standard 8-channel and 12-channel multichannel pipettes from all major manufacturers including Eppendorf, Thermo Fisher, Rainin, and Gilson. The crush-resistant turret design prevents basin deformation under the tip-loading force of any standard multichannel pipette.
How long is the sterility expiration on the sterile variants?
Sterile Heathrow Scientific polystyrene reservoirs carry a 4-year sterility expiration date from the manufacturing date, printed on each package.
Quality Assurance
Heathrow Scientific polystyrene reagent reservoirs are certified DNase-free, RNase-free, and Pyrogen-free from lot testing. Sterile variants carry a 4-year sterility expiration and are manufactured under quality systems validated for molecular biology and cell-based assay applications.
