Question:
What is the difference between qualitative and quantitative filter papers?
Answer: Qualitative filter papers, like the StonyLab type, are primarily used for general filtration applications and provide moderate particle retention. In contrast, quantitative filter papers are designed for specific analytical applications, providing higher precision and lower ash content. Users can expect the qualitative filter paper to suffice for general lab tasks, whereas more precise measurements would require switching to quantitative varieties. -
Question:
Are these filter papers sterile?
Answer: StonyLab Qualitative Filter Paper Circles are not pre-sterilized, making them unsuitable for applications requiring sterile filtration. Users needing sterile conditions should ensure to take proper sterilization steps themselves or look for specifically marketed sterile filter papers. This distinction is important for laboratory protocols involving microbiological or cell cultures where contamination must be strictly avoided. -

StonyLab's Qualitative Filter Paper Circles come in a pack of 100 and have a 46mm diameter cellulose filter paper with 20-micron particle retention medium filtration speed. According to various customer reviews, this filter paper works well for filtering fine charcoal and other fine particulates. It is also reported to hold up well with water, alcohol mixtures, solvents such as chloroform, vacuum filtration of small amounts of concentrated acids. However, one customer had trouble trying to fit the 56mm filters with Stonylab porcelain buchner filters. The temperature range that these filters work with is not specified on the packaging. Furthermore, the item is for laboratory use only and is not food safe.
