Description
The
Biochrom WPA CO7000 is a portable colorimeter designed for use by
doctors and medical technologists in small and medium sized
clinics.
Ideal for tropical and field
conditions
The unit has been tropicalised to protect
it in hot and humid conditions (to 45°C and 70%, respectively); the
10 gelatin filters are encased in glass to prevent fungal growths
appearing and the PCB has been conformally coated so that
individual components are sealed to prevent corrosion. The
instrument is powered by an internal rechargeable NiMH battery or
by external power allowing it to be used where the power supply
could be unreliable. Using the instrument connected to the mains
electricity supply automatically recharges the battery.
Easy to use and
clean
The CO7000 is very easy to use as there are
only three buttons (On/Off, Reference and Test).
The wavelength required is selected by rotating an integral
filter wheel. The filters are at 400, 440, 470, 490, 520, 550, 580,
590, 680 and 700nm enabling assays in the wavelength range 400 to
700 nm to be measured.There is a drain hole at the bottom of the
cell compartment so that spillages do not affect the
instrument.
Ideal for biochemical colorimetric
analysis
The instrument has been designed as an
“open” system so that test kits for clinical and medical
applications from virtually any supplier can be used. Examples
of routine assays that can be measured in serum and plasma include
Albumin, Cholesterol, Glucose, Creatinine, Total Protein,
Haemoglobin, Urea and those in cerebrospinal fluid include Glucose
and Total Protein. The samples can be measured in either standard
10mm pathlength cuvettes (a minimum of 400µl is required) or in
10/12/16mm diameter test tubes (adapters are included with the
instrument).
