Chemistry Analyzer Pointe 180 II

General Information

The Pointe 180 II is a small bench top analyzer designed to read and calculate the results of in-vitro clinical diagnostic assays on human serum, plasma, or urine as well as any other application requiring absorbance or concentration readings.

The analyzer is provided with 43 pre-programmed test parameters and is capable of storing up to 120 assays in memory for later recall.
The analyzer is equipped with a built in vacuum pump and external waste bottle with level sensing.
The analyzer is supplied with a removable flowcell to allow for use of 1 cm square as well as 12 mm round cuvettes.
The analyzer is designed with many features to minimize operator error, such as stable factory calibration, pre-programmed calculations, visual and audible feedback, flags and error messages.

In addition, it will store up to 512 patient results, 512 control results, 20 patients on a work list and 15 tests per patient

Pointe 180 Analyzer

Features

Bichromatic Photometer

Differential wavelengths to correct imperfections in test tubes or square cuvettes and to help remove interfering substances. Six standard filters with two optional filters (340-700nm)

Temperature Controlled Cuvette

Constant 37° C cuvette and cuvette well when optional tube or square cuvettes modes are used.

Internal Temperature Control

The analyzer monitors the incubator and cuvette temperatures. The temperatures are automatically corrected and the actual temperature in degrees (C) is displayed on the screen.

Lamp Saver Feature

The instrument automatically shuts off the lamp if the instrument has not been used for 15 minutes. This feature can preserve the lamp for up to two years, depending on the actual usage.

QC Tracking Feature

The instrument software can store control values and create Levy-Jennings plots.

Work List and Patient Reports

The instrument can create, stored and print work list and patient reports to on-board thermal printer to external printer and PC.

Different Cuvette Modes

The analyzer flowcell is removable to allow use of round 12 mm glass tube or 1 cm square cuvettes.

Flip-Up Display

Large 240 x 128 pixel graphical display.

Preprogrammed Chemistry Procedures

Optimized parameters for Pointe Scientific reagents are preprogrammed. 120 open channels.

Kinetic Plots

Shows kinetic plots in real time.

Maintenance Free

The analyzer does not require any scheduled maintenance procedures.
