Zenit UP

Description:
Fully automated processor for ELISA and IFA methods. The instrument is able to manage 4 ELISA microplates and 16 IFA slides simultaneously in the same work session; up to 10 tests can be run at a time
Samples:
From 117 to 169 sample tubes of 13mm or from 90 to 130 sample tubes of 16mm; it is possibile to use different tube sizes in the same run
Predilution:
264 predilution cuvettes allow automatic sample predilution with optimization of cuvette number
Specific Reagent Racks:
Up to 10 specific reagent racks, each one with 1 reagent position and 8 calibrator/control positions
Common Reagent Rack
10 positions for shared reagents
Diluent Rack
6 or 7 positions for ELISA and IFA sample diluents
Bar Code Reader On Board:
Automatic reading of sample codes when the sample tubes are placed in the work area; the system is able to discriminate between not readable barcodes and missing sample tubes
Liquid Handling:
Very accurate and fast X-Y-Z movement with 3 independent needles; 2 to dispense and with its own liquid sensor, the third one dedicated to IFA slide washing
Aspiration:
From 8μl to 1000μl, 1 μl resolution
Dispensation:
Inaccuracy ± 1% at 100μl
Need Washing:
Internal and external washing in specific washing basin
External Reservoirs:
1 system liquid tank, 1 waste tank and 6 buffer tanks all equipped with level sensors

APPLICATION SOFTWARE

A user friendly software allows to setup the work list, run a session, create and store the patient reports. It runs under Windows XP and Windows 7 and shows several features:

− simultaneous execution of ELISA and IFA sessions − overnight incubations
− integrated bar code reader allowing automatic sample code acquisition − management of 3 row slides and mosaic slides (as HEp-2+Tissues)
− setup of a new work list also when a session is running − different levels of user permissions
− step by step session execution − host computer interface (LIS)
− print out of results, work lists, rack configurations − several instruments can be driven by the same PC

ELISA FEATURES

Optimized racks for calibrators, controls, sample diluents, conjugates, substrates, stop solutions and cleaning solution
Liquid Reservoirs:
4 tanks for microplate washing buffers
Dispensation:
Single or duplicate dispensation of calibrators, controls and samples
Microplate:
Up to 4 microplates can be dispensed, washed, read and incubated independently from 36° to 45°C
Microplate Washing:
Two 8 nozzle on line manifolds able to self-conform to different microplate heights
Reading System:
8 independent photometric channels for mono and bichromatic readings
Optical Filters:
405nm, 450nm, 550nm e 620nm filters
Reading System:
