equipment. Green means the equipment is in normal state, yellow means the
equipment is in the self-checking state, and red means the equipment is in the
pre-warning state, which is convenient for users to understand the state of the
dehydrator simply and intuitively.

With reagent management system (RMS), users can monitor the use of reagents based
on the number of cassettes, dehydration cycles or dehydration days.

There are three ultrasonic liquid level sensors in the tissue processing cylinder. Two of
them are used for liquid level detection. The top one is used to monitor and prevent
liquid overflow. The principle of ultrasonic detection is highly reliable, and it is not
easy to cause false alarms due to the accumulation of impurities on the probe surface.

The retort is equipped with a high reliability concentration detection sensor for reagent
concentration monitoring, which can detect the concentration of ethanol and other
reagents.

The cylinder lid of the tissue processing cylinder is automatically locked and opened by
the electronic lock, and is equipped with a double triggering device, so as to ensure the
safety and reliability of the cylinder lid locking.

The cylinder lid of the tissue processing cylinder has a heating effect, which can prevent
liquid from condensing on the inner wall of the cylinder lid during the dehydration
process, thus reducing cross-contamination and loss of reagents. The inner wall of the
cylinder lid is also coated with a Teflon plating layer, which serves to reduce the
residual adhesion of paraffin and reagent on the surface of the cylinder lid, facilitating
the cleaning of the inner wall of the cylinder lid.

The operator can choose two dehydration process modes of delay start or immediate
start, allowing for flexibility of the workflow.

The reagent bottle has position detection and blue light indicator, which serve to monitor
whether the reagent bottle is in the right place or not, and allows for easy observation
of reagent level. To ensure the normal operation of the dehydration program, the blue
light transmission function can make the liquid level in the reagent bottle clearly
visible, which is convenient for users to observe.

The HP300 Plus Processor has a total of 4 paraffin cylinders, among which the volume
of 3 paraffin cylinders is 4.2L. The 4th paraffin cylinder is a paraffin filling cylinder
with a volume of 5.6L. The wax bath has two scale lines for easy observation of the
liquid level. The paraffin cylinder can be supplemented or replaced if the paraffin in
other paraffin cylinders is insufficient or replaced, without affecting the normal
dehydration process.

The equipment has independent liquid and gas passages. The pumping pressure is about
-40kpa and the discharge pressure is about 30kpa.

The equipment is equipped with an innovative paraffin purification feature for removing
solvent residue in wax, extending its service life.
