32 Density Testing Saves Time in Lab
Most scientists know that accurately determining the density of a substance is a critical part of the research process. Adam Equipment’s density kit is a valuable tool to help laboratory workers assess the density of their materials. Combine the density kit with the Adam PW analytical balance and the process becomes even more reliable and precise.
Traditionally, density determination has required measuring the sample material: fi guring out the volume, weighing the sample, dividing the volume by the mass, and fi nally coming up with the density. The process is not only complicated and tedious; it can be inaccurate.
Testing of both solids and liquids is possible using the density kit. That means that even samples with densities greater or less than that of water can be determined. The balance software will calculate density using water, ethanol or paraffi n as selectable references. The software also allows the user to enter the density of any reference liquid directly.
The density kit is installed on the fl oor of the PW’s enclosed weighing chamber. The kit’s beaker holds the reference liquid and may be reused to test as many samples as needed. The user simply selects the density application from the built-in menu options. If a reference liquid is used other than what is already programmed into the balance, the user can enter the density for that reference liquid. The application prompts the user through the process: weigh the sample in air using the sample cup on top of the stand, then in the reference liquid using the sample cup suspended on the wire. The balance software calculates the density automatically.
Shown with Adam Equipment’s PW analytical balance, the density kit consists of a glass beaker, a suspended weighing cradle to replace the standard pan, independent support for the beaker of fl uid, thermometer with clip for suspension in the fl uid and glass sinker of known volume for determination of fl uid density.
Adam’s PW analytical balances offer a quick and easy way to measure to 0.1mg. The PW provides 16 weighing units, including a custom unit and features durable metal construction, standard internal motorised calibration and a large backlit dual display that shows text prompts to help the user set up the balance quickly. Highlighted tare keys stand out for accessibility, while other buttons operate set-up functions, turn the balance on or off, send data to a printer, calibrate and change modes and weighing units.
The RS-232 interface enables data transfer from the balance to printers or computers. This allows foolproof data recording and traceability, letting the operator focus on data analysis. Other useful features include built-in applications for density, percentage, comparison and check weighing, plus counting and dynamic/animal weighing

Name Change for Leading Materials Technology Group
World-leading materials technology group Ceram is set for a new identity to refl ect an expanding portfolio. The international company is changing its name to Lucideon from 1 February. The fi rm, based in Staffordshire, has acquired new businesses over the years and the move is designed to bring them together under one banner. The change will also help grow the business, which offers materials development, testing and analysis, resource effi ciency and assurance to clients around the globe.
Lucideon is a name that has been chosen carefully. It is made up of two words with ‘Lucid’, as in making things clear and intelligible, and ‘Eon’ meaning a period of time.
The company, which also counts US-based testing and analysis fi rm M+P Labs amongst its group, will be given a fresh look as a result of the change of identity, with a new logo, signage and website.
Tony Kinsella, Chief Executive, said: “The name change will help bring all of our operations together under one identity and give us a strong base to move forward.
“As the group has acquired new interests, the range of different company names has become confusing for our clients. So, we have come up with a single identity that will incorporate all of our businesses and which will refl ect what we stand for as an organisation – independence, accuracy, creativity and responsiveness. The change will also help us to offer customers an even wider range of services. We hope they will support the new name and that Lucideon will become as familiar to them as Ceram is now.”
Mr Kinsella insists the new brand identity won’t affect the service provided by the company. He said: “Only the name is changing – customers will still be able to talk to the same people at the same locations and receive the same great customer service. “We’ll be using a fresh logo and we’re creating a new corporate website at
www.lucideon.com which will act as a portal and information site, directing customers to the services they need and the location they require.”
Ceram works predominantly in the Construction, Ceramics, Power Engineering and Healthcare sectors, working with multinational companies around the world.

Super Air Condenser is Reviewed by American Chemical Society Radleys FindenserTM
The air condenser design, which does not require running water to operate, was developed by senior research scientists and engineers at AstraZeneca, who wanted to develop an effective air condenser to work with low boiling point solvents and reduce on-site water consumption. Water-cooled condensers typically use one to four litres of water per minute which just runs to waste.
The review of Findenser highlights that some chemists do not appreciate the amount of water wasted, mainly because they do not pay the utilities bill. There is however an acknowledgment of laboratory fl ooding and associated damage caused by leaking connections to water-cooled condensers.
Findenser comprises of a glass condenser with an external fi nned aluminium jacket, between which a small amount of water is permanently sealed. The design of the glass inner and fi nned aluminium jacket means Findenser has a much greater surface area and heat transfer capacity than a standard air condenser, making it effectively a ‘super air condenser’. Tests have shown that it can replace the need for water-cooled condensers in over 95% of common chemistry applications.
Radleys is internationally recognised as an innovation leader with a commitment to supporting chemical research in a safer, cleaner and more sustainable manner. They are delighted by the ACS review. Findenser offers a signifi cant step forward to reduce consumption of a precious resource and eliminate the costs associated with water purchase and disposal.
Findenser can be used in vessels up to 2 litres with up to 1 litre of solvent. It comes with a variety of popular joint sizes

A Safety Guide for using Laboratory Heating Blocks
Asynt in conjunction with the Department of Chemistry, University of St Andrews (UK) and Advanced Chemical Safety Inc (USA) have produced an 8-page illustrated document to provide laboratory staff with an In Best Practice Guide to safe use of heating block systems.
Heating blocks provide a safe, convenient and productive alternative to heating mantles and oil baths for heating round bottomed fl asks, tubes and vials. Used in combination with a standard hotplate stirrer - heating blocks such as the Asynt DrySyn range have proved themselves with their ability to outperform the heat-conducting properties of oil baths. They pose a far lower fi re risk and their use makes the clean-up of glassware far easier as there is no residual oil contamination on the outside of the fl asks. In addition to accelerating your chemical reactions - heating blocks ensure a safer, cleaner, healthier working environment.
Drawing upon the expertise and experience of Asynt and independent chemistry experts the illustrated In Best Practice Guide leads you through glassware inspection, setting up your reaction, heating your reaction and the post-reaction cool down phase.
