Complete Guide to Using Liquid Nitrogen Tank Bucket: From Selection to Maintenance

The small bucket inside the liquid nitrogen tank is a crucial tool for connecting the ultra-low temperature environment with the operator, and its importance is often underestimated. This article will comprehensively analyze this small yet crucial accessory.

1、 The core function of carrying buckets

Sample protection: providing a stable low-temperature environment for cryovials

Operational safety: Maintain a safe distance between the user and liquid nitrogen

Convenient access: achieve fast positioning and retrieval of samples

Temperature buffering: reduces temperature fluctuations during sample retrieval

2、 Key points for material selection

Aluminum alloy version:

Advantages: Lightweight (only 300-500g), fast thermal conductivity

Disadvantage: Slightly inferior durability

Applicable: Frequently used routine samples

Stainless steel version:

Advantages: Strong corrosion resistance and long service life

Disadvantages: Large self weight (800-1200g)

Applicable: Important samples for long-term storage

3、 Key design details

Bottom drainage hole:

Standard type: 3-5 circular holes with a diameter of 8mm

Optimized: Grid like drainage design

Function: To prevent the accumulation of liquid nitrogen and prevent splashing

Anti slip handle:

Material: Silicone/Teflon coated

Angle: 15 ° ergonomic tilt

Pattern: Anti slip diamond mesh design

4、 Usage standards

Preprocessing process:

New bucket requires stepped cooling for first use

Pre cool with liquid nitrogen vapor for 5 minutes first

Fully immerse and let it stand for another 10 minutes

By mastering these professional knowledge and usage skills, you will be able to maximize the performance of the liquid nitrogen tank bucket, ensuring sample safety and efficiency. Remember, proper usage can extend the lifespan of the bucket by 3-5 times, which is an important aspect of laboratory cost control.
