● Do not open the instrument during use.
● Do not touch/operate the touch screen when the instrument is in operation.
● The instrument must be placed in a clean and ventilated environment to avoid
corrosive gas and strong magnetic field interference, to avoid direct sunlight and
strong light source.
● Instrument working conditions should remain between 0°C and 35°C, with relative
humidity below 85%.
● Appropriate PPE (Personal Protective Equipment) must be worn when dealing with
toxic, corrosive, or contagious substances.
● Local safety regulations must be followed when handling or discarding such waste.
In case of spatter or leakage, disinfect immediately with appropriate disinfectant to
prevent contamination of laboratory personnel and equipment.
● Only technicians from the manufacturer are authorized to repair, replace or
otherwise reconfigure any components.

Safety rules you should follow whenever working with any electrical appliance includes:
● Connect instrument to power adapter with a three-core grounding socket
conforming to safety standards of 120V～(60Hz).
● Confirm power is off when connecting the power cord.
● Confirm the voltage and frequency of the AC power is consistent with instrument
requirements.
● Ensure hands are dry when operating the power switch.
● Power off instrument before removing the power cord.
● Do not allow power cord to touch hot surfaces of the instrument.
● Power off the instrument before cleaning.
● Power off the instrument when no longer in use.
Electromagnetic Compatibility
The BioGX pixl Real-Time PCR Platform conforms with emission and disturbance
immunity requirements specified in EN60601-1-2. It is the manufacturer's responsibility
to provide the customer or user with the electromagnetic compatibility information of
the real-time PCR platform. The user is responsible for ensuring the electromagnetic
compatibility for proper function of the real-time PCR platform.
It is recommended that the electromagnetic environment be evaluated prior to the
use of real-time PCR platform.
Do not use the real-time PCR platform next to strong radiation sources (such as unshielded
RF sources), otherwise it may interfere with the normal operation.
Product Overview
The BioGX pixl Real-Time PCR Platform is a portable, high performance real time
quantitative PCR system equipped with a 4-channel fluorescence optical system, powered
by ultra-low-light Complementary Metal Oxide Semiconductor (CMOS) bio-imaging sensor.

The platform is optimally suited for applications where portability, and fast time-to-result is
required. Applications of pixl are point-of-care molecular diagnostics test (POCT; Clinical
clearance required), food safety and environment testing, agriculture, or research lab use
where bench space is limited.

Hardware Set-up Guide
Starting the BioGX pixl Real-Time PCR Platform
The platform is powered through an external AC/DC power adapter. The power adapter
accepts AC input ranging 110V to 240V and produces DC output of 16V.
The DC power input connector port is located at the back of the instrument. Once the
power is provided, the green power indicator light will turn on.
