Heathrow Scientific Dual Solution Reservoir HS20821A | 50mL Basin + 12×5mL Wells, Autoclavable, Pack of 25

Standard reagent reservoirs handle one solution at a time — for workflows requiring two different reagents in alternating wells, or a large shared volume alongside small individual aliquots, that means two separate reservoirs, two separate setups, and double the bench footprint. The Heathrow Scientific Dual Solution Reservoir (HS20821A) eliminates this by combining a single 50mL basin on one side with 12 slotted 5mL individual wells on the other — two reservoir formats in one footprint. The 12 angled 5mL wells guide multichannel pipette tips to the bottom of each well for complete reagent recovery, while the open 50mL side handles bulk dispensing with a standard single-channel or multichannel pipette.

Autoclavable polypropylene construction withstands standard steam sterilization cycles for sterile applications. The 4.9 × 2 × 1.5 in footprint keeps bench space consumption minimal. Sold as a pack of 25 in natural (clear/white) polypropylene.

Features and Benefits

• Two Reservoir Formats in One — 50mL Basin + 12 × 5mL Wells: One side provides a standard open 50mL basin for bulk multichannel dispensing; the other provides 12 individual 5mL slotted wells for dispensing small, precise volumes — eliminating the need for two separate reservoir types in dual-reagent workflows.

• Angled 5mL Wells for Complete Reagent Recovery: The 12 individual wells are angled at the bottom to guide pipette tips to the lowest point of the well — enabling near-complete reagent recovery from small-volume wells where flat-bottom reservoirs leave dead volume that cannot be aspirated.

• Autoclavable Polypropylene — Sterile Applications Ready: Steam-sterilizable for use in aseptic workflows — supports dual-reagent dispensing in cell culture, sterility testing, and pharmaceutical manufacturing environments where contamination control is mandatory.

• Compact 4.9 × 2 × 1.5 in Footprint: The dual-function design delivers two reservoir capabilities in a footprint barely larger than a single standard reservoir — freeing bench space in high-throughput workstations where surface area is a limiting constraint.

• Pack of 25 — High-Throughput Supply: 25 reservoirs per pack provides adequate supply for high-volume plate preparation workflows and multi-day experimental runs without requiring frequent reordering.

Laboratory Applications

• Two-Reagent Plate Preparation: Use the 50mL basin for the primary reagent and the 12 × 5mL wells for a secondary reagent or control solution — dispensing both components from a single reservoir unit without swapping reservoirs mid-protocol.

• Small-Volume Precious Reagent Conservation: Use the 5mL individual wells for expensive or limited-supply reagents — antibodies, growth factors, enzyme stocks — where loading into a full-size 50mL basin would waste costly material that cannot be recovered from dead volume.

• Cell Culture Media & Supplement Dispensing: Dispense base culture media from the 50mL side and concentrated supplement stocks from the 5mL wells into the same plate — combining two dispensing steps into a single reservoir change under the biosafety cabinet.

• Sterile Pharmaceutical & Bioprocess Applications: Autoclave before use for sterile dispensing of media, buffers, and process solutions in pharmaceutical manufacturing and bioprocess development environments.

Frequently Asked Questions

Can I use both sides of the Dual Reservoir simultaneously?
Yes — the 50mL basin and the 12 × 5mL wells are on opposite sides of the same reservoir. Load each side with a different reagent and pipette from either side as needed during the same dispensing session.

What pipette formats work with the 5mL individual wells?
The 12 slotted 5mL wells are designed for use with single-channel pipettes and compatible with standard pipette tip formats. The angled well bottom guides tips to the lowest recovery point for minimal dead volume.

Is the Dual Solution Reservoir certified DNase and RNase free?
The HS20821A is manufactured from polypropylene and is autoclavable, but DNase/RNase-free certification is not listed for this SKU. For RNA/DNA-sensitive applications requiring certified-free consumables, consider the certified polystyrene reagent reservoir series (120637–120649).

Quality Assurance

Heathrow Scientific Dual Solution Reservoirs are manufactured from polypropylene under rigorous quality standards and are autoclavable for sterile laboratory applications. The angled well design is validated for complete reagent recovery from the 5mL individual wells.
