Heathrow Scientific Reagent Reservoir, 55 mL, Non-Sterile, 100/Bulk, Polystyrene | 120752

Heathrow Scientific 120752 Reagent Reservoir 55 mL Non-Sterile Polystyrene is a Polystyrene reagent reservoir designed for efficient liquid handling in laboratory applications.

Heathrow Scientific 120752 is a 55 mL non-sterile polystyrene reagent reservoir for multichannel pipetting, sold as 100/Bulk pack. Made from polystyrene and certified DNase-free, RNase-free, and Pyrogen-free, these reservoirs deliver molecularly clean performance for general-purpose pipetting workflows that do not require full sterility. The trough features a V-shaped bottom for maximum reagent recovery, crush-resistant corner turrets, stacking tabs to prevent nesting, and pour-off spouts on all four corners for spill-free pouring. The bulk format is the most cost-effective option for high-throughput labs that use large quantities of reservoirs where sterility is not a requirement.

Features & Benefits

• DNase/RNase/Pyrogen-Free: Certified clean from biological contaminants — suitable for nucleic acid workflows, immunoassays, and cell-based assays where nuclease or endotoxin contamination from plasticware would compromise results, without the cost premium of sterile packaging.
• V-Shaped Bottom for Maximum Recovery: Tapered trough channels reagent to the lowest point, allowing complete aspiration with minimal residual volume — reducing waste of expensive reagents during high-throughput pipetting runs.
• Pour-Off Spouts on All Four Corners: Corner spout design enables spill-free pouring from any angle, reducing the chance of dripping and allowing easy transfer of residual reagent back into stock containers.
• 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.
• Anti-Stick Stacking Tabs: Molded tabs prevent stacked reservoirs from fusing together, so individual units 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 on both the top edge and inner walls allow quick visual volume estimation during reagent prep without a separate measuring step.
• 100/Bulk — Best Value Format: Bulk packaging delivers the lowest per-unit cost across the Heathrow 55 mL reservoir range — ideal for labs running high volumes of multichannel pipetting steps where sterile individual wrapping is unnecessary.

Laboratory Applications

The 120752 non-sterile bulk reagent reservoir is the high-volume workhorse format for labs that run large numbers of multichannel pipetting steps daily. ELISA plate loading, cell viability assays, colorimetric assays, and automated dispensing setups are all common use cases where sterile packaging is not required and the DNase/RNase/Pyrogen-free certification is sufficient. Drug discovery and high-throughput screening labs that process hundreds of plates per run often stock the 120752 for its clean certification and case-quantity availability. For workflows requiring full sterility — such as RNA extraction, RT-PCR, or cell culture under aseptic conditions — use the Heathrow Scientific 120750 sterile 55 mL reservoir (100/Single Bag). For non-sterile alternatives from other brands, see the Globe Scientific disposable reagent reservoirs also available at LabSupplies.

Frequently Asked Questions

What is the difference between SKU 120750 (Sterile, 100/Single Bag) and SKU 120752 (Non-Sterile, 100/Bulk)?
Both are 55 mL polystyrene reservoirs with identical dimensions, V-bottom design, and DNase/RNase/Pyrogen-free certifications. The key difference is sterility: 120750 is electron beam sterilized and bagged individually, while 120752 is non-sterile and shipped bulk. Use 120750 for RNA work, PCR, and cell culture under aseptic conditions. Use 120752 for ELISA, colorimetric assays, and general multichannel pipetting where sterility is not required.

Are 120752 reservoirs autoclavable?
No. Polystyrene reagent reservoirs are single-use disposables and are not rated for autoclaving. Autoclaving PS will cause warping and deformation. If reusability or autoclavability is required, consider polypropylene reagent reservoirs.

Can I use 120752 reservoirs for RNA workflows if they are DNase/RNase-free?
The DNase/RNase-free certification means the material is free of nuclease contamination, which is a necessary condition for RNA work. However, for RNA applications under aseptic conditions (e.g., RNA extraction, RT-PCR setup in a biosafety cabinet), full sterility is typically also required. In that case, use the 120750 sterile variant instead.

What multichannel pipette formats are compatible with the 120752?
The 120752 is compatible with standard 8-channel and 12-channel multichannel pipettes. The trough length and width accommodate standard multichannel tip arrays in both row and column orientations. It is also compatible with single-channel pipettes for reagent dispensing.
