I. Equipment Introduction

Thank you for purchasing and using the AIS-4 Compressed Air Microbial Sampler, which

represents the latest concept of compressed air microbiological testing

AIS-4 of compressed air microbial sampler is based on Anderson impact principle of

ntaa highly efficient porous compressed air microbial sampler, according to the const

erspeed sampling theory design to get accurate.sampling results. When the samples we

hetcollected, the compressed air was subjected to the step-down limit treatment, and

2.9 m /1microbial particles mixed in the compressed gas were impacted at a rate of 12.5 -

o thetsec (23.1 to 23.5 m/sec at 200 L/min) The surface of the medium is equivalent

an 1hAnderson Principle 5(Grade 6at 200L /min), ensuring that all particles larger t

ish wasdmicron (0.65 micron at 200L/ min) are all collected. After sampling, the culture

placed in aconstant temperature incubator.The culture medium creates the best

e results.lenvironment for maintaining the activity of bacteria, ensuring accurate and reliab

edium,mIn vivo microbes are in suitable environment and are well nutrient in the culture

resulting in high-speed growth. Finally, the experimental results are obtained.

VIII. Operation Instruction

1.touch button description:

Start key: OK, enter the sample

Menu key: toggle menu settings

Select key: toggle the currently selected digit, enter the record in the main interface

Return key: return to the main interface

▲: set the number or option plus one

▼: Set the number or option minus one

2.Sampling steps:

(1) Preparation of Petri dishes: Please select the medium required for microbial culture

according to the requirements of the experiment and prepare the corresponding plate.

Before starting sampling, make sure that the storage temperature of the sampling petri dish

is at the appropriate temperature.

(2) Sterilization: Unplug the gas dispersing head and reverse the rotation to remove the

sampling head for sterilization (see section 3 of this chapter) and check that no petri dishes

are placed on the dish. After sterilization, return the sampling head to the original position

date and time

of the instrument and cover the gas dispersing head.

(3) access to the catheter: make the compressed gas (tank) through the catheter access to

the instrument behind the left side of the interface, while the right side of the interface to

maintain the catheter connected to the gas distribution head.

(4) Power on: turn on the power switch, the screen lights into the main interface, keep the

default "program-controlled sampling" mode unchanged, press the "Start" button.

(5) Sampling gas group number setting: Press "▲" "▼" to change the code of the

sampling gas group (0 ~ 99), press "Select" key to switch the digital bit, set the press

"Start" to the next step The (The group number is only saved as a sampling gas type code

to this record for later review)

(6) Sampling volume setting: the same use of "▲" "▼" to change the size of the sample,

use the "Select" button to switch the digital bit, set the press "Start" to the next step.

(7) Adjust the flow to the specified value: the internal intake solenoid valve has been

opened, the airway is in a smooth state, please open the external compressed gas (tank)

valve, compressed gas will be through the air inlet →pressure control valve →gas

flow (See section 4 of this chapter). After adjustment, press "Start" to proceed to the next

step. Adjust the gas flow meter and the air pressure regulating valve to match the flow rate

(see section 4 of this chapter).

(8) Start sampling: At this time the internal intake solenoid valve is temporarily closed,

please open the sampling head, put into the culture dish, and then cover the sampling head,

press the "start" button to start sampling, the screen shows the current sampling volume

And the remaining time.

(9) Remove the Petri dish: At the end of the sampling there will be buzzer reminder, the

internal intake solenoid valve closed again, the screen prompts the sampling is completed,

the sampling record automatically saved, please open the rotary probe, remove the culture

dish, Culture dish cover, affixed with a label or write the number, and culture the plate in

incubator in accordance with the detection requirements .

(10) self-purification mode: the screen also prompts whether to enter the self-purification

mode, under normal circumstances recommended after sampling at least 1 minute to

reduce the sampling process to reduce the airway residue. Please click "▲" "▼" key to

change the self-purification time, and then press "Start" to start the self-purification. Note

that during the self-purification process, the barometric pressure source is still an external

compressed gas (tank). Do not disconnect the external compressed gas. In addition, if you

still need to continue to repeat the same compressed gas sampling, you can not directly

press "back" to start the next sampling.

(11) Sampling is completed: Please close the external compressed gas (tank) after the

valve, then the intake duct from the back of the instrument pull out.

Sampling precautions.3

The AIS-4 of compressed air microbial samplers can not be used for toxic, corrosive, (1)

flammable and explosive gases, if necessary, please contact the manufacturer or agent to

. purchase other models

Sterilization: The porous sampling head can be sterilized by autoclaving at 121 °C (2)

for 30 minutes (or wiped with 75% alcohol) at the high pressure steam sterilizer. The gas

dispersing head, the Petri dish and the appearance of the instrument are also used 75%

alcohol for wipe sterilization. After each sampling test, if you want to continue sampling

another compressed gas (cans), you need to repeat the sterilization treatment.

(3) When installing the Petri dish, the dish must be stuck in the center of the base and the

bottom of the dish is pressed down to the base.

(4) Pressing the "return" key before sampling is complete will forcibly terminate the

sampling operation. The internal airway solenoid valve will be automatically closed and

the sampling volume will be stopped, but the sampling record will be saved.

4.Device instructions

Catheter Interface: Gas duct interface with easy to plug can be replaced design, pull out

when you need to press the interface of the blue plastic ring, and then pull out the catheter,

and insert the catheter directly into the reverse pull the catheter To strengthen the blue

plastic ring sealing effect.

Pneumatic control valve: the left side of the instrument for the air pressure adjustment

knob, adjust the need to pull the knob out slightly, counterclockwise rotation to open the

air flow channel, clockwise rotation to close the air flow channel.

Gas flowmeter: the right side of the gas flow meter below a flow adjustment knob, the

same counter-clockwise rotation to open the air flow channel, clockwise rotation to close

the air flow channel.

Purifier: the purifier for the consumables, after a long period of use, the purification effect

will be reduced, it is recommended to use the time accumulated for 200 hours or more

than a year after the replacement. When replacing, remove the top side of the baffle screws,

remove the purifier from the instrument, remove the clamp with a screwdriver to remove

the purifier tube, take a new purifier and push it back into the instrument. Into the

compressed gas into the self-purification mode to check the phenomenon of no leakage,

and finally lock the baffle screws.

5.the system function menu description

Working mode selection

In the main interface, press "▲" "▼" key to select the working mode as "program

control", "manual control", "self-purification mode"

Programmed Sampling: The recommended program controls the sampling mode. For

details, see Section 2 of this chapter.

Manual control: to meet some of the user's manual control of special needs, in this

mode, press the "start", enter the manual control interface, the bottom of the screen shows

the current two airway solenoid valve status, press "▲" Change the state of the airway

solenoid valve, press the "Select" button to switch to select another airway solenoid valve.

Self-purification mode: Press "▲" "▼" key to change the self-purification time, press

the "Start" button to start self-purification. In the access to compressed gas (cans)

conditions, open the self-purification after the gas through the air inlet →purifier →

pressure control valve →gas flow meter →sampling head, through the air flow to the

sampling process of exhaust airway residue. (Equivalent to the "open air open" state in

manual control mode).
