Tobacco Toxicity Test Device (Squirrel Cage Method) with Ring Furnace
Product introduction
The smoke toxicity test device (squirrel cage method) is applicable
to the test standard of GB/T 20285 "Hazard classification of smoke
toxicity of materials". The test principle is: the constant
velocity of the strip sample is constant speed by the annular
furnace with stable heating. The constant velocity mobile scanning
heating is used to obtain a stable flue gas flow through the
blowing of the flue gas in the quartz tube through the constant
velocity carrier gas flow, and is sent into an independent squirrel
cage, and then the state of the experimental white rat is observed,
and the test result is judged.
Product parameters
1.The test equipment includes a ring furnace, a furnace
displacement device, a quartz tube device, a temperature
calibration device, an poisoning box, a rotating cage, a
temperature control device, an air flow control device, and a
three-way valve.
2. The annular furnace consists of a furnace shell, a furnace body,
a furnace tube and an electric heating wire. The inner wall of the
furnace tube is a heating surface. The diameter of the furnace tube
is 47±1 mm, the length is 100±1 mm, and the temperature range is
not less than room temperature to 1100 degrees.
3.Temperature calibration device, imported Omega K thermocouple
with outer diameter of 1mm, welded with 1CR18NI9TI material
temperature sensitive sheet, and can be connected with computer
software to calibrate the temperature rise in the furnace.
4. Japan Omron temperature control device, using PID temperature
control method, the furnace temperature accuracy is better than ± 1
degree, the temperature fluctuation at rest is better than ± 0.1
degrees, the temperature fluctuation during exercise is better than
± 2.5 degrees.
Furnace displacement device, the displacement rate of the ring furnace is 10±0.1mm/min, the movable distance is ≥600mm, and the Japanese Panasonic servo motor and PLC control mode are adopted.
Product Feature and Application

1mm, wall thickness 2 ± 0.5mm, length 1100 ± 100mm, quartz boat
length is 400mm, width 32 ± 1mm.
2. Mouse cage and poisoning box, the mouse cage is made of
aluminum, the quality of the cage is 60±10g, the mouse cage can be
flexibly rotated on the bracket, there is no fixed static point,
the poison box is colorless. Made of transparent plexiglass with an
effective space of about 9.2L, it can hold 10 mice for the test.
3. Air flow control device, air drying and purification device, can
be used for air cleaning and drying; carrier gas mass flow meter
device can digitally display air flow, the range is 0-10L / min,
the accuracy is better than 0.1L / min, dilution gas The mass flow
meter device can digitally display the air flow with a range of
0-5L/min and an accuracy better than 0.1L/min.
4. Automatic control electric three-way ball valve, protection
grade IP-65, electrical and mechanical double limit, with overheat
protection.
5. Taiwan Advantech data acquisition module, (does not accept
self-made MCU module and board), 1 set of standard test software,
can display calibration temperature value and curve, test
temperature value and curve, movement speed and curve of each cage.
6. Optional: Mouse motion recording system, using photoelectric
switch to monitor the movement state of the mouse cage, computer
software can display the angular velocity of the cage at each
moment.
