Excellent sampling flexibility is achieved through the optional cell holder assemblies, allowing the use of 10, 20, and 40mm cells, whilst multiple sampling handling is possible with the four cell carriage. For temperature-dependent measurements a heated cell block is available. Toggle navigation Menu. Clinical Rapid Tests. Bacteria Testing.

Quick Links. Download this manual. Table of Contents. Page 2 Safety Please read this information carefully prior to installing or using this equipment. The unit described in this manual is designed to be operated only by trained personnel. Any adjustments, maintenance and repair must be carried out as defined in this manual, by a person qualified to be aware of the hazards involved.
It is essential that both operating and service personnel employ a safe system of work, in addition to the detailed instructions specified in this manual.
Other than for those items defined in the maintenance procedures herein there are no user serviceable items in this instrument. Removal of covers and attempted adjustment or service by unqualified personnel will invalidate the warranty and may incur additional charges for repair. References should always be made to the Health and Safety data supplied with any chemicals used.
Generally accepted laboratory procedures for safe handling of chemicals should be employed. Do not use hazardous or flammable substances in the instrument. Lire et suivre les instructions fournies avec la plus grande attention. Page 4 7. Abnehmbares Anschlusskabel nicht durch unangemessen bewertete Kabel austauschen. Leggere attentamente queste istruzioni prima di installare o utilizzare il dispositivo.
Qualsiasi operazione di regolazione, manutenzione e riparazione deve essere effettuata sulla base di quanto indicato nel presente manuale da personale qualificato consapevole dei rischi connessi.
Adottare le procedure di laboratorio generalmente accettate per la gestione delle sostanze chimiche. Non utilizzare sostanze pericolose o infiammabili sullo strumento.
Qualsiasi condizione di errore deve essere immediatamente segnalata al responsabile per la manutenzione. Page 5 3. No utilice sustancias peligrosas o inflamables en el instrumento. Lea atentamente y siga las instrucciones correspondientes. The visible spectrum is covered by eight gelatin filters incorporated within the unit. An analogue output of 1mV per digit is available on the rear panel.
Mains Cable 3. Pack Disposable Plastic Cuvettes 4. The power consumption is 20W. The standard 2 metre mains lead supplied with the unit is fitted with an IEC type connector which can be plugged directly into the Power In socket on the rear panel. Wavelength Select - Thumbwheel used to select the correct wavelength for the specific tests being performed. Blank Control - This control is used when standardising the unit. The Blank control is then set to give the correct reading.
Concentration - This control is used when the mode switch is in the Conc 1 and 2 positions. These ranges are extensions of the Absorbance mode, allowing the reading obtained to be set to a value convenient to the standard concentration. The reading may be increased or decreased by up to a factor of ten. Sample Area - Samples may be presented in 10 x 10mm cuvettes of standard or semi-micro volumes or test tubes.
Sample Area Lid - The lid should be kept closed, when necessary to eliminate the possibility of erroneous results caused by the ingress of stray light. For many determinations, the lid may be left open. Zero - A preset control which should rarely require adjustment and is provided to offset photocell dark current. Jack Socket - Connection socket for the external 12V d. Connect the unit to the mains supply and switch on. Allow 15 minutes warm-up period at this point to ensure the optical and electronic systems have sufficient time to stabilise.
Insert the test cuvette black cuvette supplied with the unit into the sample chamber. The wavelength reading is not critical at this point. The display should read zero. Adjustment to this reading can be made by use of the Dark Current Offset control located on the rear panel. If adjustment is required the blank and zero settings should be re-checked until they are both correct.
Remove the test cuvette from the sample chamber. Fill a cuvette to within 1cm of the top with distilled or deionised water and place in the sample chamber. Close the sample chamber lid. Select the required wavelength or interference filter.
Set the display to read using the Blank Control. The reading should be stable. Remove the cuvette from the unit. The is now ready for use. NOTE: During sample measurement the sample area lid should ideally be kept in the closed position to eliminate the possibility of erroneous results caused by the ingress of stray light. For many determinations, however, the lid may be left open without causing significant errors. Sample Measurement 1.
Allow minute Warm-Up prior to use refer to 3. Select the required filter position for maximum absorbance.
If this is not known, the colour complimentary to that of the standard solution can be selected from the list given below. The chart may be read from left to right or right to left, i. Page Good Practice Guidelines 6. The unit is now ready for operation in the Absorbance mode. Operation in the Concentration mode can be performed by selecting either Conc 1 or 2 using the Function Switch. The standard value should be set to a convenient reading using the Concentration Control.
The unit will now read directly in sample concentration. Remove the blanking filter from the filter compartment and insert the interference filter to be used. The degree of attenuation varies from zero on position F1 through to a maximum on F4. In most normal circumstances position F1 will be most appropriate. If, however, lower than expected absorbance values are obtained, it is probable that the detector circuit is saturating and a range with more attenuation should be selected.
The unit is now ready for use. Maintenance The has been designed to give optimum performance with minimum maintenance. The only maintenance required is to clean the external surfaces with a damp cloth and mild detergent and keep free from dust.
To give added protection when not in use the unit should be disconnected from the mains supply and covered with the optional dust cover. For longer term storage or re-shipment, it is recommended that the unit be returned to the original packing case. Light Source Replacement The only routine maintenance which may be required is the replacement of the light source due to failure.
This can be confirmed by considering the cuvette chamber. In the event of a justified claim Cole-Parmer will replace any defective component or replace the unit free of charge.
This warranty does NOT apply if damage is caused by fire, accident, misuse, neglect, incorrect adjustment or repair, damage caused by incorrect installation, adaptation, modification, fitting of non-approved parts or repair by unauthorised personnel.
