ASIs Reagent Reservoirs for Multichannel Trays are versatile and compatible not only with multichannel pipettes but also with single-channel pipettes. These disposable polystyrene reservoirs can accommodate standard 4-channel, 8-channel, 12-channel, and various specialized pipettes, including single-channel pipettes. To facilitate convenient and dripless pour-off of unused reagents and solutions, all versions feature recessed "spouts" in each corner. Additionally, the reservoir bottoms are designed with a sharply tapered "V" shape to minimize waste and reagent consumption. For user convenience, the reservoirs are equipped with easy-to-open white tear strips, and when stacked, they do not adhere to each other, ensuring a smooth laboratory workflow.
