Laboratory Products 17 High Quality Light Microscopes for Every Application Now Available in the UK & Ireland


The Microtec range of microscopes and accessories is a relatively new name to the British market. Based on high manufacturing quality, excellent imaging capability and reliability, the company has rapidly become one of the leading UK suppliers of light microscopes and accessories. The company was founded by Clive Cowen, an Honorary Fellow of the Royal Microscopical Society (1989). He began his career with Zeiss light microscopes developing a passion for improving imaging performance. He went on to run his company developing and supplying specialist microscope systems to manufacturers worldwide. He became involved with the RMS and teaching training courses on microscopy. This led him to China and the importation of basic school level microscopes.


Cowen then embarked on a plan to establish a line of microscopes designed and manufactured specifically targeting the exacting requirements of the UK market. High quality optics and mechanics were needed and this led to building a family of suppliers, each bringing a specific expertise to the end product. The result is Mictotec.


The Microtec range now covers a wide variety of the needs in the life sciences and material sciences and provides excellent performance at economical prices. Technical backup is another aspect critical to the supply of a good product. Users need to know they can pick up the ‘phone and speak to someone who knows what they are talking about and this service is delivered by Cowen and his colleagues at Microtec. Additional support and advice is available through a carefully selected dealer network. The microscopes all come with a lifetime guarantee and stock levels ensure prompt deliveries. A selection of instruments available is outlined here. The range extends from basic routine instruments to advanced microscopes for research and exacting requirements.


For example, take the Microtec MI-u. This is a research microscope with an ergo head for comfortable viewing. It can be equipped with incident fluorescence and phase contrast. There is a wide of choice of flat field achromat and flat field fluorite objectives. Contact Microtec today and describe your needs and let Cowen and his team put together a matched offering for you.

ADVERTORIAL Handheld Laboratory Flow Meters


Alicat portable gas flow meters measure and display mass flow, volumetric flow, line pressure or barometric pressure, and gas temperature. Portable gas flow meters make GC checks, calibrations and audits fast and easy. They also fulfil a number of lab measuring functions all within the one device. All portable flow instruments offer laboratory-grade accuracy and multivariate readings that update 1000 times a second. Other flow devices can be checked in situ without the need to remove them to a calibration workshop or to send them offsite. The configurable engineering units ensure that all common flow measures such as Ln/min, SLPM, mln/min, sccm and even mass can be accommodated. Alicat flowmeters do not require conversion factors, or k-factors, as the 98+ gases stored onboard ensure that the stated accuracy remains true and that for example 1 LPM remains as 1 LPM regardless of the gas type.


AFS–Portable Gas Flow Calibrators A portable gas flow standard that is ready for anything.


When a calibration process requires the utmost accuracy, the AFS flow standard delivers. It features Alicat’s most advanced calibration for optimal performance across changing temperatures, plus an on-board relative humidity sensor to maintain its accuracy all the way up to 100% RH (non- condensing). These advancements make possible a 0.75% of reading accuracy spec that requires no additional full-scale component. Low pressure drop allows calibration of volumetric flow rates with minimal impact. Averaged measurements and onboard data logging make it easy to gather multivariate flow data.


• Available ranges: max 0-50 slpm, min 0-5 sccm • Turndown ratio: 200:1 when flowing air; 20:1 when flowing other gases or gas mixes • Flow accuracy: +/- 0.75% of the reading (NIST-traceable) • Typical measurement response time constant: 5-10 ms • No warm-up time required • Compatible gases: 98 pre-loaded selectable gas calibrations; additional mixtures definable with COMPOSER


MB–Portable Gas Mass Flow Meters Laboratory-grade flow verification, anywhere you need it.


Alicat’s portable flow flowmeters make calibration or validation simpler and faster by reducing downtime and disruption. Instant-on and real-time readings for multiple gases across wide flow ranges ensure periodic checks can be completed within just a few minutes. Flows can be calibrated with NIST-traceable accuracy for a variety of gases down to 1/200th of full scale or user-created gas compositions can be defined via COMPOSER™.


• Available ranges: max 0-5000 slpm, min 0-0.5 sccm/0-500 sµlm


• Turndown ratio: 200:1 (standard gases) or 100:1 (corrosive gases)


• Standard accuracy calibration, NIST-traceable: +/- (0.8% of the reading + 0.2% of the full-scale range)


• Optional high-accuracy calibration, NIST-traceable: +/- (0.4% of the reading + 0.2% of the full-scale range)


MWB–Low Pressure Drop Portable Gas Mass Flow Meters


Measure flow with minimal system impact, anywhere you need it.


‘Whisper’ series portable flow meters with low pressure drop are the perfect measuring and calibration instruments for mass and volumetric flow rates. Low pressure drop minimises system impact, enabling flow measurement at near- atmospheric pressures or when there is little available system pressure.


• Available ranges: max 0-1000 slpm, min 0-0.5 sccm/0-500 sµlm


• All other specifications are as per the MB Series


Alicat portable measuring and calibration devices are available for gas flow, liquid flow and pressure calibration checks. 46151pr@reply-direct.com


Alicat’s Whisper™ A portable mass flow meter, perfect


for lab, service call, or testing • Measures, verifies or calibrates gas mass and volumetric flow • High accuracy, no warm up • More than 98 gas calibrations on-board—change on the fly • 1000 measurements/second • Pressure drops as low as 4 mbar
