Sample bottles, also known as sampling bottles, purification bottles, sterile bottles, clean bottles, filter bottles, filter bottles, etc., are mainly used for collecting liquid samples for particle contamination testing, containing high-purity reagents, containing particle standard substances and standard samples. Sample bottles are used for pollution detection, and their cleanliness directly affects the accuracy of the detection results. Improper use of sample bottles may result in loss of analyte volatilization, chromatographic impurities caused by solvent and spacer interactions, and mechanical damage to the automatic sampler.

　　

　　Thermo Fisher Sample BottleAccording to the volume score, there are two types: 150ml PP plastic and 250ml high silicon boron. According to material, it can be divided into two categories: glass and plastic. Glass bottles are easier to clean and heat-resistant, but they are fragile and prone to breakage; Plastic bottles are more economical, durable, and safe to use, but they cannot be sterilized under high pressure. There are various sizes of sample bottles, such as 150ml particle counter dedicated sampling bottle (filter bottle) with an outer diameter of 50mm, a diameter of 22mm, and a height of 130mm; 250ml particle counter dedicated sampling bottle (filter bottle) with an outer diameter of 70mm, a diameter of 30mm, and a height of 140mm.

　　

The temperature to which Thermo Fisher sample bottles can be heated depends on their material and design. Here are several common sample bottle materials and their maximum temperature tolerance:

　　

1. Borosilicate glass: This glass material is commonly used in high-temperature resistant sample bottles and can typically withstand temperatures up to about 500 ° C.

　　

2. Polytetrafluoroethylene (PTFE): Sample bottles made of this high-performance plastic material can withstand temperatures up to 260 ° C.

　　

3. Polyphenylene sulfide (PPS): Sample bottles made from this material can also withstand temperatures up to 200 ° C.

　　

4. Ceramic materials: Some high-temperature resistant sample bottles are made of ceramic materials, which can withstand higher temperatures, usually between 800 ° C and 1000 ° C.

　　

In summary, when using Thermo Fisher sample bottles for high-temperature heating, it is important to carefully read the product manual, understand their maximum allowable temperature, and follow the correct operating procedures to ensure safety and accuracy of experimental results.
