PRODUCTS AND SERVICES Looking at the microbiology


Microbiological Validation Services offers a range of support services. These include environmental monitoring of cleanrooms; bioburden, sterility and endotoxin testing; sterilisation validations, including dose setting/auditing; and accelerated ageing to ASTM F1980-07. Currently based in Rotherham, South Yorkshire, the company is moving to new, purpose built premises in Sheffield later in 2011.

Vacuum plasma unit


Dyne Technology is showcasing the new vacuum plasma unit at the MEDTEC UK show in Birmingham in April. The unit, which is portable and small enough to fit onto a bench, is offered as a cost- effective solution to the problem of improving surface wettability. The equipment requires a 240v 13 amp electrical supply and comes equipped with its own vacuum pump to eliminate the need to hook up with any separate vacuum supply. Featuring touch screen control, the see-through door enables users to see their parts being treated in the large chamber. All of the main parameters of treatment power, time and vacuum level are adjustable for total process control. Plasma treatment improves the bond strength when glueing, printing or coating and improves overall wettability to a range of parts, including, optical lenses, catheters, cannulae and small components. Chris Lines, Managing Director at the company said, “We expect this competitively priced plasma system to be of particular interest to anyone operating in the medical industry for laboratory or small scale production environments as the equipment is so very versatile and handles all sorts of materials.”

Testing services


International Laboratory Services (ILS) says its microbology department is fully equipped to analyse raw materials and medical devices in accordance with pharmacopoeial methodology. Routine testing is performed under the scope of UKAS accreditation, although it can work to customers’ preferred methodology when requested. The company is GMP compliant, and MHRA and FDA inspected. Its range of services includes sterility, microbial limit, bioburden, and preservative efficacy testing. It conducts irradiation dose setting determination studies to ISO 11137 and method development and validation.

Sensor technology


Highly sensitive LBA differential pressure sensors from Sensortechnics are able to detect very small pressure differences in respiratory devices such as ventilators, spirometers, sleep diagnostic equipment, nebulisers and oxygen concentrators/ conservers.


The LBA series offers differential low pressure measurement with ranges of 250 and 500 Pa full scale. The LBA sensors perform fully analogue on-chip CMOS signal conditioning to allow for linear and temperature compensated outputs, with high differential pressure resolution of typ. 0.1 % and fast response times of typ. 1 ms. The sensors are based on thermal flow measurement of gas


through a micro-flow channel integrated within the sensor chip. This narrow channel decreases the flow through the LBA sensor by several magnitudes compared with other flow-based pressure sensors, says the company. The extremely low gas flow ensures high immunity to dust contamination and condensation and allows the use of connecting tubes and input filters without the need to recalibrate or correct the output signal. Because the flow impedance is predefined at the sensor chip level, the LBA series provides small and cost-effective PCB- mountable housings.

Industrial laser manufacturer, JK Lasers’ fibre and Nd:YAG lasers benefit from a feature called Process Cycles. A process cycle consists of a number of individual steps that combine to define a laser process. Each step can be configured to use different laser parameters so that the user can create complex manufacturing processes. Depending on the application, process cycle execution can be initiated using minimal or no external control system interface. Creation and monitoring of the process cycle is managed through LaserView or FiberView software, depending on the laser being used. Software tools are also available to allow integration of the process cycle control functions into the user’s own user interface software. The benefits of process cycles include significant reduction or
