Item#: 11442
Condition: Tested
Manufacturer: Waters
The Acquity UPLC Sample Manager injects the samples it draws from microtiter plates or vials into the chromatographic flow stream. A locating mechanism uses a probe to access sample locations and draw sample from them. In the needle overfill load-ahead mode, the sample manager can perform an injection in approximately 15 seconds. The first injection requires additional overhead time.
The sample manager accepts standard footprint plates (5.03 ±0.02 inch × 3.365 ±0.02 inch), that conform to ANSI standards (maximum height = 2.2 inches, including covers). You may program any combination of these plates and vial holders for automated sample processing. Samples are loaded into the sample manager via the front door or the optional sample organizer, which transfers samples back and forth between the two instruments. The sample manager can maintain samples at any temperature between 4 to 40℃ in 25℃ or less ambient conditions.
The sample temperature control is settable in 0.1℃ increments (assumes an ambient temperature of 25.0℃). At an ambient temperature of 21.0℃ or lower the sample manager will maintain the temperature of the sample compartment down to 4.0℃ with a tolerance of -2.0/+6.0℃, when configured with the maximum number of vials and/or plates.
