Vacuum filtration, sometimes known as Buchner filtration is used to isolate a solid product or impurity from a liquid filtrate. Any solid product or impurity can be left on the filter paper present within the funnel and easily removed, whilst the filtrate passes through the funnel into the flask at the bottom, to be used further or discarded. Whilst the set-up can be considered simple in itself...
Comparing vacuum pumps - how to tell which provides a stronger vacuum?
When choosing a vacuum pump for any lab or industrial process such as vacuum filtration, rotary evaporators or for a vacuum oven, you may want to compare different models.
Since vacuum can be expressed in so many different units (mbar, bar, Torr, mm Hg, Pa, psi...) this can be difficult to do!
Looking at the ultimate vacu...
Selecting the right filter for your lab filtration will help to ensure you get the desired results.
After considering whether you need vacuum or gravity filtration, you then need to select a suitable filter material and size.
[caption id="attachment_9504" align="aligncenter" width="300"] With so many types and sizes of filter paper available, make sure you choose the right one for the tas...
Filtration under vacuum, also known as Büchner filtration, is commonly used to isolate the solid precipitate from a solution.
This technique is used in syntheses, for example when a reaction has yielded a solid, or in analyses including gravimetric analysis of suspended solids.
Although performing the filtration is simple, several pieces of equipment are needed which must all fit together, so...
Vacuum filtrations using a Buchner flask and funnel with a vacuum pump are commonly used to isolate a solid of interest from a liquid.
Most commonly a porcelain Buchner funnel with a filter paper placed on top is used, but in some instances a sintered disc funnel is more appropriate.
But when would you select a sintered disc funnel? And how should a sintered disc filter funnel be cleaned ...
Thanks for sharing such a great information.. It really helpful to me.. I always search to read the quality content and finally i found this in you post. keep it up!
I came across your article about "DPD Tablets" on Camlab Info, and it's a valuable resource for anyone seeking information about water testing and analysis using DPD tablets. Your explanation of their usage and significance in water quality monitoring is quite informative.
This article on nanocolor tube tests is a gem for analytical enthusiasts. The idea of zero calibration is intriguing, and your detailed explanation makes it accessible. The step-by-step process helps demystify the technique for beginners like me. The use cases you've highlighted, particularly in...
Grant have introduced the new Controlled Rate Freeze Thaw (CRFT), which is a liquid nitrogen and cryogen free controlled rate freeze and thaw system for cryopreservation in a wide range of applications. Cryopreservation is a process where biological materials such as cells, tissues...
A dipslide is a means of testing the microbial content of liquids. This is a common method of monitoring and measuring microbial activity within many systems and commonly cooling systems. Usually the use of a dipslide is the first line of defence for the testing of microbial issues that could be...
