As a mature market, filtration moves forward incrementally through improvements in filter media and housings. Improvements in lab instrumentation and techniques demand a new level of sample preparation that was unnecessary a decade ago. High-performance liquid chromatography (HPLC) in particular has undergone a renaissance due to the advent of sub-two-micron columns.
Top 5 Questions You Should Ask When Buying Lab Filtration Products
- What sort of facility do you work in and what sort of applications do you use filtration for? This will help you determine whether disposable filters are right for you or not. Disposables make sense for any process where cleaning and reuse must be validated but tend to be more expensive than multiple-use filters.
- What are the costs of using disposable filters versus the cost of the time and materials needed to clean a multi-use filter? This will help you determine the most cost-effective choice for your lab.
- How can the company’s filters eliminate steps in your lab’s workflow?
- How pure do you need your samples to be? Again this helps clarify if disposable or multi-use filters are best for you and also helps narrow down which specific types of filters you’ll need.
- What sort of service or support does the company offer?
Recent Trends in Lab Filtration:
- The last great technologic wave in filtration was the introduction of singleuse or disposable products. Single-use filtration membranes and cartridges have become standard fare in large-scale processing in pharmaceuticals, biotechnology, food, and other regulated industries.
- Providing equivalent filtration equipment at large and small scale is now standard at large filtration companies. Similarly, process intensification— essentially eliminating steps—has become a buzzword both in manufacturing and during development.
- Tangential flow filtration (TFF), also called cross-flow filtration, is a relatively modern technique that involves causing fluid to pass across instead of directly through a filter membrane’s pores. The sweeping motion causes fluid to pass through and retains particles but significantly reduces clogging.
- At small scale, centrifugation remains the method of choice for concentrating process fluids.
