Heathrow Scientific 120753 Reagent Reservoir 55 mL Non-Sterile PVC is a clear translucent PVC reagent reservoir designed for streamlined pipetting procedures.
Heathrow Scientific 120753 is a 55 mL non-sterile PVC (polyvinyl chloride) reagent reservoir for multichannel pipetting, sold as 100/Bulk. PVC construction makes these reservoirs more flexible and softer than polystyrene (PS) alternatives, which can be an advantage in labs where slight trough flexing helps dislodge residual reagent or where PVC's specific chemical compatibility profile matches the reagents in use. Each reservoir is certified DNase-free, RNase-free, and Pyrogen-free, with a V-shaped bottom for maximum reagent recovery, crush-resistant corner turrets, stacking tabs, and drip-free pour-off spouts on all four corners.
Features & Benefits
- PVC Construction: Polyvinyl chloride offers a different chemical compatibility and flexibility profile compared to polystyrene — suitable for aqueous reagents, buffers, and many biological solutions. Always verify PVC compatibility with your specific reagents before use with organic solvents or strong oxidizers.
- 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.
- 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 multichannel pipetting runs.
- Drip-Free 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 to 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: Reference marks on both the top edge and inner walls allow quick visual volume estimation during reagent preparation without a separate measuring step.
- 100/Bulk — High-Volume Format: Bulk packaging delivers cost-effective pricing for high-throughput labs that use large numbers of reservoirs per day and do not require individually wrapped, sterile packaging.

Laboratory Applications
The 120753 PVC reagent reservoir suits multichannel pipetting workflows that involve aqueous buffers, saline solutions, antibody diluents, enzyme substrates, and other water-based reagents compatible with PVC. ELISA plate loading, cell viability assays, immunofluorescence staining protocols, and general plate-based screening are common applications. PVC reservoirs are a preferred choice in some labs due to institutional procurement standards or prior validation with specific assay protocols. Note that PVC is not compatible with many organic solvents, concentrated acids, or strong oxidizers — for solvent-compatible applications, consider polypropylene reservoirs.

Frequently Asked Questions
What is the difference between 120752 (Polystyrene) and 120753 (PVC) at the same 55 mL / 100/Bulk format?
Both are non-sterile, DNase/RNase/Pyrogen-free, 55 mL bulk reservoirs with identical dimensions. The key difference is material: 120752 is polystyrene (PS), while 120753 is PVC. PVC is more flexible than PS and has a different chemical compatibility profile — it is well-suited for aqueous reagents but not for organic solvents. Choose based on your reagent compatibility requirements or existing validated protocols.
Is the 120753 PVC reagent reservoir compatible with organic solvents?
PVC has limited compatibility with many organic solvents, including acetone, THF, ethyl acetate, and chlorinated solvents. It is generally compatible with dilute aqueous buffers, saline, alcohols at low concentrations, and most standard biological reagents. Always verify PVC compatibility with your specific reagents using a solvent compatibility chart before use.
Are 120753 PVC reservoirs autoclavable?
No. PVC reagent reservoirs are single-use disposables and are not rated for autoclaving. PVC will deform and release plasticizers under autoclave conditions. These are designed for single-use disposal after each pipetting session.
What multichannel pipette formats are compatible with the 120753?
The 120753 is compatible with standard 8-channel and 12-channel multichannel pipettes. The trough dimensions accommodate standard multichannel tip arrays in both row and column orientations, as well as single-channel pipettes for reagent dispensing.
