CGOLDENWALL 16L Cryogenic Container Liquid Nitrogen Tank YDS-15 User Manual

1. สินค้าหมดview

The CGOLDENWALL YDS-15 Cryogenic Container is a high-performance liquid nitrogen (LN2) storage tank designed for long-term, low-temperature preservation of biological samples, medical materials, and other sensitive items. Constructed from durable aluminum alloy, it features advanced vacuum insulation to ensure extended holding times and minimal LN2 evaporation. This manual provides essential information for the safe and effective use of your cryogenic container.

2. ข้อมูลด้านความปลอดภัย

คำเตือน: Liquid nitrogen is an extremely cold substance (-196°C / -320°F) and can cause severe cold burns or frostbite upon contact with skin or eyes. Always handle with extreme caution.

• อุปกรณ์ป้องกันส่วนบุคคล (PPE): Always wear appropriate cryogenic gloves, a face shield or safety glasses, and long-sleeved clothing when handling liquid nitrogen or working near the container.
• การระบายอากาศ : Use the container only in well-ventilated areas. Liquid nitrogen rapidly vaporizes into gaseous nitrogen, which can displace oxygen and lead to asphyxiation in confined spaces.
• การสะสมแรงดัน: Never seal the container completely. The lid must allow for the escape of gaseous nitrogen to prevent dangerous pressure buildup. Ensure the stopper is not airtight.
• การรั่วไหล: In case of a liquid nitrogen spill, evacuate the area immediately and allow the nitrogen to evaporate. Ensure adequate ventilation before re-entering.
• ความเข้ากันได้ของวัสดุ: Do not place materials directly into liquid nitrogen that are not designed for cryogenic temperatures, as they may become brittle and shatter.
• การยก: Use proper lifting techniques or equipment when moving a filled container due to its weight.

3. ส่วนประกอบผลิตภัณฑ์

The CGOLDENWALL cryogenic container is designed with several key components to ensure efficient and safe storage. Understanding these parts is essential for proper operation and maintenance.

Figure 2: Internal Structure of a Cryogenic Container (Storage Type). Key components include the outer shell, vacuum insulation, inner liner, neck tube, and canisters for sampที่เก็บของ

• เปลือกนอก: คภายนอกasing, typically made of aluminum alloy, providing structural integrity.
• ซับใน: The internal vessel that holds the liquid nitrogen and sampเลส.
• ฉนวนสุญญากาศ: The space between the outer shell and inner liner is evacuated to create a vacuum, significantly reducing heat transfer and minimizing LN2 evaporation.
• Multilayer Insulation: Additional reflective layers within the vacuum space to further reduce radiant heat transfer.
• Neck Tube: A narrow tube connecting the inner liner to the outside, minimizing heat entry while allowing access.
• Cover/Lid: Seals the neck tube opening, often with a loose fit to prevent pressure buildup.
• รับมือ: For carrying the container.
• Canisters (Dewars): Small, cylindrical containers placed inside the tank to hold samples. The YDS-15 model includes 3 canisters.
• Adsorbent: Material used to maintain the vacuum over time.

5. คำแนะนำในการตั้งค่า

1. การแกะกล่อง: Carefully remove the cryogenic container from its packaging. Inspect for any signs of damage during transit. If damage is found, contact your supplier immediately.
2. การจัดวาง: Place the container on a stable, level surface in a well-ventilated area, away from direct sunlight or heat sources. Ensure there is sufficient space around the container for safe operation and ventilation.
3. การทำความสะอาดเบื้องต้น: Before first use, ensure the interior of the container and canisters are clean and dry. Use a clean, lint-free cloth. Do not use abrasive cleaners.
4. การทำความเย็นล่วงหน้า (ไม่จำเป็น แต่แนะนำให้ทำ): For optimal performance and to minimize initial LN2 boil-off, it is recommended to pre-cool the container by adding a small amount of liquid nitrogen (e.g., 1-2 liters) and allowing it to sit for several hours or overnight before filling to capacity. This helps to cool the inner vessel gradually.
5. Canister Insertion: Place the empty canisters into the container's neck tube. Ensure they are properly seated.

6. คู่มือการใช้งาน

6.1 Filling with Liquid Nitrogen

1. ความปลอดภัยเป็นสิ่งสำคัญที่สุด: Ensure all safety precautions (Section 2) are strictly followed. Wear appropriate PPE.
2. ถอดฝาออก: Carefully remove the container's lid.
3. Transfer LN2: Slowly pour liquid nitrogen from a suitable transfer vessel into the cryogenic container. Avoid splashing. Fill to the desired level, typically leaving some headspace to prevent spillage and ensure proper venting.
4. Observe Boil-off: Initial filling will result in significant boil-off (visible vapor). This is normal as the container cools down. Reduce the pouring rate if boil-off is excessive.
5. เปลี่ยนฝา: Once filled, replace the lid loosely. Do not seal tightly. The lid is designed to allow vapor to escape.

6.2 Storing Sampเลส

1. เตรียมสampเลส: มั่นใจ samples are properly sealed in cryovials or other suitable cryogenic storage containers. Label all samples clearly.
2. Load Canisters: วางสที่เตรียมไว้amples into the designated slots within the canisters.
3. Lower Canisters: Carefully lower the loaded canisters into the liquid nitrogen tank using the provided handle or retrieval tool. Avoid sudden movements that could cause splashing.
4. การบันทึกข้อมูล: Maintain a detailed inventory of all stored samples, including their location within the canisters and tank.

6.3 Retrieving Sampเลส

1. ความปลอดภัยเป็นสิ่งสำคัญที่สุด: สวมใส่อุปกรณ์ป้องกันส่วนบุคคล (PPE) ที่เหมาะสม
2. ค้นหา Sampเลอ: Refer to your inventory to identify the correct canister and sampตำแหน่งที่ตั้ง
3. Retrieve Canister: Carefully lift the desired canister using the retrieval tool. Minimize the time the canister is exposed to ambient air to prevent warming and excessive LN2 loss.
4. ลบ Sampเลอ: Quickly remove the required sample from the canister.
5. Return Canister: Immediately lower the canister back into the liquid nitrogen.
6. เปลี่ยนฝา: Ensure the lid is replaced loosely after access.

7. การบำรุงรักษา

• Regular LN2 Level Checks: Monitor the liquid nitrogen level regularly (e.g., weekly or bi-weekly, depending on usage and holding time). Do not allow the LN2 level to drop below the top of the stored sampเลส.
• การเติม: Refill the tank with liquid nitrogen as needed to maintain optimal storage conditions.
• การทำความสะอาด: Periodically, when the tank is empty, clean the interior and exterior surfaces with a mild detergent and water. Rinse thoroughly and ensure all parts are completely dry before refilling. Do not use harsh chemicals or abrasive materials.
• Vacuum Integrity Check: A significant increase in LN2 evaporation rate indicates a potential loss of vacuum integrity. If this occurs, the container may need professional inspection or replacement.
• Lid and Stopper: Ensure the lid and stopper are clean and free from ice buildup. Replace if damaged.
