Axygen Reagent Basin 12 Wells Autoclavable Sealed Case of 25 Reservoirs

The Axygen RES-MW12-HP-SI Reagent Basin is a specialized liquid handling vessel designed to facilitate complex pipetting protocols, particularly serial dilutions or the addition of multiple distinct reagents simultaneously. Unlike standard single-trough reservoirs that hold one liquid for all channels, this unit is divided into 12 separate, parallel troughs. This compartmentalized geometry aligns perfectly with the standard 9 mm spacing of 8- and 12-channel pipettes, allowing a researcher to use a 12-channel pipette to aspirate up to 12 different liquids at once, or to perform row-wise dilutions directly in the reservoir before transferring to a microplate.

These reservoirs are high profile, referring to the vertical dimensions and volume capacity of the reservoir (typically holding approximately 3 mL per channel). The unit is manufactured from medical-grade polypropylene (PP), a material choice that offers two significant advantages over standard polystyrene basins: high chemical resistance and thermal stability. This makes the reservoir fully autoclavable, allowing labs to reuse the unit if desired, or to use it with harsh solvents that would dissolve standard plastic. The bottom of each channel usually features a V-shape to minimize dead volume and ensure maximum sample recovery.

The "SI" designation indicates that these reservoirs are supplied sterile and individually wrapped. This packaging is critical for sensitive applications such as PCR setup or cell culture, where maintaining the sterility of the reservoir until the moment of use is paramount. The rigid polypropylene construction also provides a stable footprint on the benchtop, preventing tipping during aggressive pipetting steps.
