Revvity, 1296-071, DBS Puncher Instrument

The DBS Puncher™ automatically punches dry blood spot samples into microtitration plates. The punch has a changeable head, so the blood spots may be 3.2 mm, 4.7 mm or 6 mm in diameter. Two plates may be loaded simultaneously and the plate height allowed is adjustable, so deep well plates can be accommodated. After punching, disk detection ensures that the disk is correctly placed in the microtitration well. The DBS Puncher may be connected to a bar code reader for indentification of the patient sample. It may be run from an external computer, receiving a plate layout which specifies the sample codes for the wells and the punch sequence. The instrument is controlled by hand or by footswitch. Ease of use is enhanced by a clear double line display, and by illumination of the area being punched.
