Specimen preparation tools
Specimen preparation tools can be considered
as recommended purchased options of MECOS-C2 microscopy system which can significantly improve quality and level of
standardization of analyses. For a few MECOS-C2 automated techniques certain
specimen preparation tools are strongly recommended to
guarantee
analyses quality.
1. Faecal Parasite Concentrator Parasep (DiaSys)
for concentration of Helminth ova and larvae, Protozoal cysts
and oocysts by ester-formalin sedimentation.

FE-5
workstation for fecal specimen preparation
(DiaSys)
Automated microscopic analysis of fecal concentrates can be performed at
reduced cost, higher accuracy and with enhanced worker safety by the FE-5, an easy-to-use workstation for rapid
location and identification of parasites, cysts and ova in human feces. FE-5 workstation eliminates the need and cost
of disposable pipettes, microscope slides, and cover slips for
faster and safer analysis of fecal concentrates.
FE-5 is a workstation that automates the process of making and manipulating
wet-mount preparations of fecal concentrates. A decrease in time needed to
read the sample is achieved, permitting technologists to rapidly spot
parasites, ova (eggs) and cysts, sometimes carried in the lower intestinal
tract of humans and animals.
The FE-5 workstation corrects the procedural shortcomings of current
methodologies in several significant ways. First of all, no special training
is required to operate the FE-5. To operate, the technologist inserts the
instrument's automatic dual aspirator into a prepared fecal concentrate in Parasep concentrator and
presses the "sample" button on the workstation's control console. Within 5
seconds, a consistent, measured amount of concentrate is automatically
transferred to the workstation's optical slide assembly (OSA) on the stage
of the microscope.
During this process, one chamber of the OSA is inoculated with a small
quantity of the fecal concentrate. The other chamber is inoculated with an
equal mix of fecal concentrate and iodine (for staining) or isotonic saline
(for dilution) as the lab prefers. Observations of the stained (or diluted)
and unstained fecal concentrate are then ready to begin. Purging the system
takes about 7 seconds, after which time the FE-5 is ready to make the next
concentrate slide.
Among its virtues, the FE-5 increases the level of safety and precision by
automating the aspiration, resuspension, staining or diluting, transfer,
presentation, and disposal of fecal concentrates. Eliminated is the need and
cost of disposable pipettes, microscope slides, and cover slips. Moreover,
because the fecal concentrate is contained in and manipulated through a
sealed system, the technologist carrying out the work is not exposed to
prolonged inhalation of chemicals such as formalin which are conventionally
used to process raw fecal material.
Flowing cavity OSA of
Fe-5 workstation with 2 channels.
Sizes of OSA chambers allow parasites free moving.
OSA is fixed on standard microscope stages. Width of a chamber
matches to width of field of view at 10x objective. The same sample
can be pump over the OSA many times for increasing analysis
reliability.

3. The
Hema Tek 2000 Slide Stainer (Bayer
Diagnostics)
provides a continous feed
loading platform that eliminates wasted time associated
with batch staining methods. Correct first-time staining
means less duplicated work. Pumps deliver fresh reagents
in precise volume for every stain while the platen
provides uniform stain from field-to-field and
slide-to-slide with stain and buffer mixing accurately
and uniformly. Slides are immediately available for
viewing upon completion of staining, and the rinse
reagent contains the optimal alcohol concentration for
proper slide drying. Dials, located on front panel,
allow for wide variation in stain intensities to suit
individual needs. Features of the Miles Hema Tek 2000
include: ·Stains up to 60 slides per hour, ·Simple to
maintain, ·Delivers precise volumes of fresh stain for
every slide, ·Offers superior control of stain and
buffer mix, ·Provides uniform staining from field to
field and slide-to-slide. |
