Heathrow Scientific Reagent Reservoir, 55 mL, Sterile, 100/Single Bag, Polystyrene | 120750

Heathrow Scientific 120750 Reagent Reservoir is a Polystyrene Sterile 55 mL reservoir designed for streamlining pipetting procedures and handling temperature-sensitive reagents.

Heathrow Scientific 120750 is a 55 mL sterile polystyrene reagent reservoir for multichannel pipetting, sold as a pack of 100 in a single bag. Each reservoir is individually electron beam sterilized and certified DNase-free, RNase-free, and Pyrogen-free — making 120750 suitable for sensitive molecular biology, cell culture, and nucleic acid workflows. The trough features a V-shaped bottom to maximize reagent recovery, crush-resistant corner turrets for structural rigidity, and stacking tabs to prevent nested reservoirs from sticking together during dispensing.

Features & Benefits

• Sterile, DNase/RNase/Pyrogen-Free: Electron beam sterilized and certified free of DNase, RNase, and Pyrogens — essential for PCR, qPCR, RNA work, and cell-based assays where contamination would compromise results.
• V-Shaped Bottom for Maximum Recovery: The tapered trough channels reagent to the lowest point, allowing complete aspiration of even small residual volumes — reducing waste and ensuring consistent dispensing to the last pipette fill.
• Crush-Resistant Corner Turrets: Reinforced corner structures maintain trough shape under normal bench handling, preventing deformation that could cause spills or uneven pipette tip immersion depth.
• Anti-Stick Stacking Tabs: Molded tabs on each reservoir prevent stacked units from fusing together, so individual reservoirs can be separated cleanly one at a time without disrupting the rest of the pack.
• 25 mL and 50 mL Graduation Marks: Two reference graduation marks printed on the trough wall enable quick visual volume estimation without a separate measuring step during reagent prep.
• Pack of 100 in Single Bag: Bulk-pack format delivers the lowest per-unit cost for high-throughput labs that run large numbers of multichannel pipetting steps per day and don't require individual wrapping.
• Flat Benchtop Stability: Designed to stay flat on the bench without warping, providing a stable platform for multichannel tip arrays during aspiration.

Laboratory Applications

The 120750 sterile reagent reservoir is designed for multichannel pipetting workflows in molecular biology, genomics, cell culture, and clinical diagnostics labs. Its 55 mL capacity and V-bottom design make it well-suited for filling 96-well plates with master mixes, antibodies, cell suspensions, or assay reagents. The DNase/RNase-free certification is particularly important in RNA-based assays (RT-PCR, RNA extraction, northern blotting) where nuclease contamination in the reservoir would degrade samples before they reach the plate. The bulk 100/bag format suits high-throughput plate-based screening labs that process dozens of plates per day. For smaller-volume applications, see the Heathrow Scientific 120637 5mL sterile reagent reservoir. For non-sterile options, see the Heathrow Scientific 120646 and 120690 reagent reservoirs also available at LabSupplies.

Frequently Asked Questions

What is the difference between the 120750 (100/Single Bag) and single-wrapped sterile reagent reservoir versions?
SKU 120750 ships as 100 reservoirs in a single bulk bag — the bag itself is sterile at time of opening, and individual reservoirs are sterile within it, but they are not individually wrapped. This format is ideal for high-throughput labs that open one bag and use reservoirs in rapid succession. If your workflow requires individually wrapped, single-use-sealed reservoirs for contamination-sensitive applications, look for single-wrap variants in the Heathrow Scientific reagent reservoir family.

Are the 120750 reagent reservoirs autoclavable?
No. Polystyrene reagent reservoirs are single-use disposables and are not rated for autoclaving. They are pre-sterilized by electron beam irradiation. Attempting to autoclave PS reservoirs will cause warping and deformation.

What pipette formats are compatible with the 120750 reagent reservoir?
The 120750 is designed for use with standard 8-channel and 12-channel multichannel pipettes. The trough length and width accommodate standard multichannel tip arrays across both orientations. It is also compatible with single-channel pipettes for reagent dispensing.

Is the 120750 reagent reservoir safe for RNA and PCR workflows?
Yes. SKU 120750 is certified DNase-free, RNase-free, and Pyrogen-free, making it suitable for RNA-sensitive applications including RT-PCR, qPCR, and RNA extraction workflows. In highly sensitive applications, use reservoirs immediately upon opening the bag and do not leave them uncovered at the bench.
