SKC sampling bag Tedlar from the United States; 232-10

SKC sampling bag Tedlar from the United States ® 232-10

1. Core Specifications

• Part Number: 232-10

• Capacity: 10 Liter

• Difference: Compared to the 232-01 (1 liter), this model has a capacity 10 times larger.

• Dimensions: Approximately 40 cm x 45.7 cm (15.75 'x 18')

• Note: Due to the large size, attention should be paid to the space during operation.

• Material: DuPont ™ Tedlar ® (PVF) film

• Thickness: 2 mil (0.05 mm)

• Characteristics: Industry standard chemical inertness, with good stability to gases such as VOCs, CO, CO2, SF6, etc.

• Pack Size: Typically 10 pieces per pack.

2. Connections&Valves

Consistent with 232-01, use a single polypropylene combination joint:

• 2-in-1 design: integrates hose interface (for inflation/exhaust) and injection spacer (for needle sampling).

• Operation: Rotate the joint to open and close the air circuit.

• Temperature resistance: The upper limit of temperature resistance of polypropylene material is about 93.3 ° C.

• Advantages: Compared to stainless steel joints, it is lighter and more cost-effective, making it suitable for sampling in general environments.

3. Main application scenarios (Specific Applications)

In addition to conventional indoor air and ambient air sampling, the 10 liter large capacity gives it a special purpose:

• Multiple analyses are required: When a single analysis method requires a large amount of gas consumption, or when the same sample needs to be distributed to multiple instruments (such as GC-MS, gas chromatography, etc.) for different indicator detection, a 10 liter bag provides sufficient sample gas.

• Cooperate with vacuum sampling box: This size is specifically designed to accommodate SKC's extra large vacuum sampling box (Extra Large Vac-U-Chamber, item number 231-944).

• Principle: Place the bag into a hard box and create negative pressure by extracting air from the box, causing the external sample gas to automatically flow into the bag. This method does not pass through a sampling pump to avoid contamination or adsorption of the pump body.

• Long term average sampling: Combined with an extremely low flow rate flow limiter, longer integration sampling can be performed.

4. Usage and maintenance suggestions

• Inflation volume: To prevent bursting, it is usually recommended to control the inflation volume at around 80% of the maximum capacity (approximately 8 liters).

• Transportation protection: Due to the large size of the bag, it is more susceptible to compression during transportation after being filled with gas. It is recommended to use hard containers or specialized boxes for transportation to avoid piercing by sharp objects.

• Cleaning: It is also recommended to clean with high-purity nitrogen gas at least 3 times before use.
