Cytiva have collaborated with TerraCycle to recycle filtration devices to help reduce how much ends up in landfills. TerraCycle was started in 2001 to help eliminate waste by making worm poop plant food from leftover food waste, and then was packaged in waste such as used soda bottles. Since 2001 TerraCycle has prevented over 8 billion pieces of waste ending up in landfills.

Soxhlet extraction is used for extracting a compound of low solubility from a solid sample (typically natural or environmental samples such as soil, sediment and more). It was invented by Franz von Soxhlet in 1879 for the extraction of a lipid from a solid sample and has since become widely used the world over. The Soxhlet extraction method uses a number of different glassware pieces. A Soxhlet...
There is a huge selection of syringe filters available in all kinds of material, pore sizes and diameters. When it comes to selecting the most appropriate one for your application this can make it seem like a bit of a minefield. We break the process down into a number of steps to help simplify selection.
1. Match pore size with your application
Most types of syringe filters come in a selec...
Levels of airborne particulate pollution is measured as a means of monitoring air quality. Airborne particulates (PM) can be solid particles or liquid droplets. They come in different sizes, compositions and origins (i.e. natural or synthetic). This means they can all have differing effects on human health. PM2.5 and PM10 are two standard particle sizes that are monitored:
Coarse particles...
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...
Filtering water samples before ICP-MS or HPLC analysis for heavy metals testing is good practice - to help protect these delicate instruments from damage caused by larger particles.
However some filters can introduce interferences which may affect the results - so what type of filter is best for heavy metals analyses?
Why filter samples?
Samples taken in the field are often high in...
Suspended solids tests are conducted as a water purity indicator, and to form part of discharge consent. The gravimetric method of suspended solids testing requires filter papers to be used, but these must be of the correct grade to ensure correct results.
We've taken a look at which filter paper grades are approved for suspended solids tests.
Which filter paper should I u...
Syringe filtration is a great, quick method of filtering samples prior to further analysis by HPLC, UV-VIS analysis or other analytical techniques.
Some samples which have a high amount of solid particulates in them can block up syringe filters, slowing down the process.
GE Whatman have designed two specialist syringe filter ranges with a clever filter structure which aims to combat this,...
The preparation of samples prior to HPLC or UHPLC analysis can be very time consuming, particularly in laboratories which analyse a high volume of samples.
Filter manufacturers Whatman have developed a range of unique devices which can cut sample prep time by 1/3, and could even save money too - the UniPrep Vials
[caption id="attachment_9638" align="aligncenter" width="300"] The UniPrep V...
When looking for filters there are a lot of different options available to suit different applications. It is important to ensure you choose the best type for your work, but what do the different terms mean? Paper or Cellulose Filters - these are manufactured from cellulose fibres and are used for general filtration. The particle retention level can go down to 2.5 µm. This type of filter pap...
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...
Purchasing items using donated funds without the burden of VAT will now save many Millions of pounds each year which can be put to better use in advancing scientific knowledge to provide new treatments and cures that will shape the medicines of the future.
Working with pressure/vacuum conditions in the lab is common but not all products are designed to withstand this. Products with appropriate geometry and wall thickness are suitable for working safely with pressure. For example, filtering flasks, desiccators, or flat flange vessels, as well as...
