Merrow Scientific are pleased to have recently supplied 
and installed a Porolux 1000 porometer at the UK site of a leading global heathcare company.
The Porolux 1000 porometer is the leading instrument on the market, combining techniques developed over the last 20 years with cutting edge hardware (precision needle valves, mass flow controllers, pressure transducers, ethernet connection, remote diagnosis etc) and easy to use and powerful software.
This latest installation is to be used for measuring through-pores in filter materials using the Porolux 1000 with its precise bubble point measurement method and pressure equilibrium measurement (ideal for samples where pores may follow a tortuous pathway).
For further details and sample testing please do not hesitate to contact us.

Altimet (represented in the UK and Ireland by Merrow Scientific)
have recently launched the Altisurf 50 in the UK. This is a ground breaking instrument for surface metrology as it is portable - meaning users can take the instrument to a point of interest to measure surface characteristics or changes, for example:
- Measuring corrosion occurring on structures (rather than having to take samples for laboratory analysis)
- Quantifying degradation of museum or art gallery pieces and the effect of cleaning solvents
- Assessing the wear on components on racing cars to ensure optimum performance and meeting of standards
- Locating on a production line for assessment of production quality
The instrument can be configured to use a non-contact confocal chromatic or interferometric optical sensor to optimise specifications for unique applications. This allows a vertical resolution of up to 5nm to be measured.
Coupled with our powerful PheNIX technology and software a wide range of surfaces and characteristics can be analysed.
The unit can also be coupled with a special stand to allow it to be used at every type of angle and direction, for example it can be used upside down to analyse a component on the underside of a car.
For further details please contact us and also visit us at the RSC Tribology meeting in April at Southampton University

Altimet (represented by Merrow Scientific in the UK and Ireland) has recently implemented the first 'line chromatic confocal sensor' in the world in a profilometer. This pushes one step forward the non-contact sensing technology based on confocal chromatic imaging.
The standard range of our confocal chromatic sensors offer the following advantages when it comes to surface measurement:
- Suited for industrial environments
- Very accurate measurements
- Insensitive to ambient lighting
- Measure on any kind of material, reflective or diffusing
- Enhanced dynamic range thanks to the light source intensity management
- Excellent price/performance ratio
- Very long lifetime light source
- Saturation-free system
- Wide choice of measuring ranges
- Low power consumption
We do have a wide range of sensors available for our Altimet systems including interferometric, high res CCD, laser, and mechanical styluses so we have solutions for most measurement applications and resolutions required. But chromatic confocal's advantages mean a lot of hard to measure surfaces and applications are now not out of reach.
The new line chromatic confocal sensor includes all of the above but also means ultra fast non-contact measurement: speeds of up to 1800 lines per second (each line made of 180 discrete points) providing up to 324,000 measured points per second, so very fast and high accurate surface measurement.
More details on the Altimet range can be seen on our surface measurement page or if you'd like further information please don't hesitate to contact us
And lastly Happy New Year to you all.

Traditionally the performance magnedrive dr
iven stirred laboratory reactors were controlled using a motor hung behind the vessel and linked to the magnedrive using a belt drive. So something like the design pictured here:
These worked great and allowed stirring up to 3300rpm and nearly 800Nmm of static torque (so capable of meeting most research requirements), the only downside was that the dimensions made them a bit unfriendly/tricky for housing inside fume cupboards. More and more customers needed to do this, and while lower specification magnedrives were available in inline format these were a bit shaky in case you needed to stir faster or your product became more viscous.
So we listened and now all our standard reactors come with inline motor and magnedrive and still with speeds up to 3300rpm and nearly 800Nmm of static torque. So still the same reactors and magnedrive performance that you'd expect from Autoclave Engineers and still designed to go to high pressures and temperatures for hours per day for 30+ years (some of our current customers still use AED reactors from the 1960s), but in a nice compact fume cupboard friendly format.

We are pleased to announce a new partnership with Altimet supplying their range of surface metrology solutions in the UK for materials characterisation/surface measurement for a wide range of applications.
Altimet have been involved in surface measurement for nearly 20 years, originally developing their systems for the demands of the Swiss watch market. Based near Lake Geneva Altimet have developed a wide range of systems designed to meet the flexibility and precision required by today's market worldwide.
The instruments are designed in a modular way to allow the use of a range of sensors for 3D high resolution profilometry. These sensors include point and line confocal chromatic sensors, interferometric, mechanical stylus, CCD sensors, lasers and other devices required for a range of applications.
Due to our wide range of sensors and PheNix electronics and software we believe we can measure almost all types of surfaces to the highest resolution. Measurements are insensitive to colour and surface optical properties so we can even measure products through glass and other glossy transparent surfaces.
Instruments are available for laboratory use and also as portable systems for analysis online or in the field (e.g. corrosion at Oil and Gas industry sites).
Further information can be seen on the surface measurement page or contact us to discuss your application in more detail.

A new version of the magnetic suspension balance from Rubotherm has been launched for measurement of vapour pressure of substances. (available in the UK and Ireland through Merrow Scientific)
Vapour pressure is an important characteristic of a chemical and has to be determined for any new substance according to current European REACH regulations.
Our new system with Kundsen cell inside the magnetic suspension balance gravimetic system allows highly accurate recording of the weight change of the Knudsen cell under ultra-high vacuum coniditions, and additionally the special design of the instrument enables the reliable temperature control of the Knudsen cell in a wide temperature range.
The new instrument design combines a high flexibility for performing vapour pressure measurements with different test substances (liquid or solid) in a wide vapour pressure range, ease of operation, and high reproducibility and accuracy.
The unique patented design of the Rubotherm system and its magnetic coupling between precision balance and the sample chamber means we can establish ultra high vacuum around the sample, but also can ensure tighter temperature control in the Knudsen cell in those conditions (which is an issue on other designs).

We will be exhibiting at the EuropaCat X conference later this month in Glasgow.
As well as displaying the latest developments from Rubotherm and Autoclave Engineers for catalyst characterisation, chemistry research and gas sorption we'll be launching a new system from BEL.
The new system, Belsorp VC, is a multi-component gas adsorption system. The instrument is based on the volumetric sorption technique with integrated micro gas chromatograph and allows analysis up to 70bar (single component gas or 35bar multicomponent gas).
The Belsorp VC provides useful information for various industrial applications such as gas storage, separation and purification.
BEL have been supplying volumetric systems for gas sorption research for over 20 years and like many other Japanese companies are leading the field in terms of technology and ease of use. Merrow Scientific are their exclusive UK and Irish partner.
For other applications where multi-component gas adsorption is of interest (for example in even higher pressures) then we also have the Rubotherm gravimetric system which is ideal for this type of application.
For further information please visit us at EuropaCat X or contact us directly.
