30 Clean-room Workbench Eliminates Particles


No matter whether it be the semiconductor fabrication or medical or pharmaceuticals industries, many sectors are attaching increasing importance to producing and manufacturing components in a clean, particle-free environment. The primary fields of application for the Spetec clean-room workbench or mini environment are in the optical, electronic and mechanical industries. The clean-room workbench can be tailored to meet customer needs and the required clean room class. In other words, the size, features and design of the workbench are adapted as required.


As a rule, the unit is made from special aluminium profiles suitable for use in clean rooms. The side walls can be made from glass or acrylic glass, or the box can be surrounded by a strip curtain. A laminar flow module is then fitted at the top, which delivers class 5 clean room conditions inside the box. This corresponds to a mere 100 0.5 µm particles. Compared with an approximate particle count of 1 million per cubic foot in a typical office or laboratory, this represents a 10 000-fold increase in air quality.


The key difference compared with a Spetec Laminar Flow Box (FBS Series, table unit) lies in the fact that the size and features of the clean- room workbench can be fully tailored to the needs of the customer, for instance in respect of the choice of work surface, which is available as perforated steel, stainless steel or hard laminate. The result is a self-contained, tailored clean-room workbench.

Save Costs with Energy-efficient Refrigerated Circulators


Laboratory circulators ensure reliable and precise temperature control of samples, test specimens and processes in basic research, material testing or in technical plants. In many of these applications, partial load operation is usually sufficient for efficient dissipation of heat. Energy-efficient refrigerated circulators can help customers save operating costs and also reduce the environmental impact.


For this reason, Julabo offers four energy-efficient temperature control instruments for different customer requirements: The new models CORIO CD-449F, CORIO CP-449F, DYNEO DD-449F and MAGIO MS-449F. All four refrigerated circulators have been developed with a focus on energy efficiency and work with natural, environmentally friendly refrigerants. In the partial load range, this can lead to significant operating cost savings and thus to a faster return on investment for many applications. At the same time, the lower energy consumption makes a positive contribution to climate protection.


Another advantage: The 449F refrigeration unit has a large bath volume. The unit is perfect for precise temperature control of larger or a variety of samples in the bath.

Unite 3 Measuring Tasks in 1 Instrument


The Easy VIS, one of the next-generation EasyPlus UV/VIS spectrophotometers produced by Mettler-Toledo, takes over the measuring tasks of up to three instruments: a colorimeter, a spectrophotometer, and special measuring methods for water testing, such as titration. All this power rests in one instrument about the size of a notebook. The results appear on screen in trustworthy accuracy, precision, and repeatability - within seconds. That saves money, time, and space.


A typical place for Easy VIS is the QC lab at small manufacturers in the food and beverage industry, environmental testing labs, or any industry needing quality control and supervising their process- or wastewaters. The Easy VIS is used during multiple steps of the production process: For inspection of raw materials, quality control of semi-finished and finished products, or testing the water quality of wastewater.


The visual user interface with workflow guidance allows you to simply scan and measure. Even untrained staff can operate Easy VIS intuitively. This increases the integrity and repeatability of the analysis and saves training time.


Easy VIS operates within a wavelength range of 330 to 1,000 nm. The light source is an easy-to-replace tungsten lamp, which any operator can replace within no time.


The partner device, Easy UV, covers the full UV/Vis spectrum with a wavelength range from 190 to 1,000 nm to cover additional applications in the UV range. Plus: The Easy UV runs with a power-saving and maintenance-free xenon-flash lamp.


25 standard-compliant colour scales in the visible range come pre-installed and can easily be used. Some examples are ICUMSA™ for sugar colour, ESBC for beer quality analysis, or OIV CIELab for wine colour determination. The results reveal the quality of the product within seconds.


Water analysis shows, for example, the concentration of Aluminium, Ozone, Chlorine, or Polyphenol. This reveals whether the water is fit for human consumption or can be used in further production. Is the wastewater safe to release? With its numerous built-in water testing methods, the spectrophotometer can quickly provide the answer.


For spectrophotometry, the sample is analysed at the wavelengths where the sample has its characteristic absorption of light. The Easy VIS measures the transmitted or absorbed light and the reading reveals the sample’s concentration or purity. More information online: ilmt.co/PL/PxLw

Instant Noise Reduction for Pneumatic Equipment Offering excellent sound attenuation properties, new Vyon®


porous plastic silencers from Porvair Sciences directly fit into the exhaust port of pneumatic equipment ensuring the noise from air escaping to the atmosphere is reduced to a safe decibel level.


Many industrial organisations use the power of compressed air in pneumatic equipment including blast cleaners, drills, forging pressures and paint sprayers. A notable drawback of pneumatic equipment is their loud operating noise. To reduce the ambient noise from your pneumatic equipment to safe, workable levels it is vital they are fitted with effective silencers.


is a porous permeable plastic made from high density polyethylene using a proprietary powder sintering process. Using this high-performance material, Porvair Sciences manufactures effective noise attenuation devices (silencers) to fit almost any pneumatic equipment. Each Vyon®


Vyon® silencer is


comprised of a sintered polyethylene body moulded to a high-density polyethylene adapter with British Standard Pipe (BSP) M5 connections or easy- to-use push-in connectors.


Once a silencer is fitted, compressed air escapes to the atmosphere by expanding through the porous body of the device. Vyon® silencers can reduce the noise from a single unsilenced exhaust port from about 90 decibels to between 60 and 70 decibels. Noise at 90 decibels level corresponds to the noise produced by a


heavy truck or underground train passing at a distance of a few feet. It is widely acknowledged that such decibel levels are dangerous, and people should not be exposed to this level of noise for any length of time. By comparison, 60 decibels correspond to the level of noise from a normal conversation at 3 feet distance and consequently is completely safe.


Manufactured in an attractive grey body / black adaptor design, Vyon® Vyon®


silencers can also be manufactured to specific configurations. More information online: ilmt.co/PL/9Rae


silencers from Porvair Sciences are available in volume to pneumatic equipment manufacturers on short deliveries. Custom 59390pr@reply-direct.com
