Environmental Laboratory 33 Thermostatic cabinets and laboratory refrigerators from


provide safe and energy-effi cient water analysis in the laboratory Record heat with heavily impacted groundwater, severe weather catastrophes with huge fl oods and destroyed drinking water infrastructure: these are just some of the current phenomena that show that water is becoming increasingly valuable. Regular water controls are mandatory and are becoming increasingly important. Laboratories are accordingly in high demand. Against the backdrop of exploding energy costs, effi cient tools are essential in this respect. Lovibond®


refrigerators for storing samples and chemicals.


The range includes energy-saving thermostatically controlled cabinets for the standard-compliant storage of water samples and reagents, as well as laboratory refrigerators with explosion-proof interiors for directive-compliant work with hazardous substances.


The thermostatic cabinets of the TC series are characterised above all by low energy consumption. This is achieved by using highly effi cient components and reinforced insulation. A control unit ensures continuous temperature control in the range from 2 to 40 °C. This makes it particularly suitable for different applications - but especially for the storage of samples and or for BOD determinations in waste water analysis. An illuminated LED display indicates the current temperature or the set temperature in the cabinet. The temperature control unit complies with the EMC directive according to IEC 61326: Electrical equipment for measurement, control and laboratory use. The temperature can be selected in 0.1 °C steps. Internal sockets ensure that equipment such as magnetic stirrers can also be stored in the thermostatic incubators while receiving the necessary power supply. Lovibond®


offers 3 models with steel doors and 2 models with glass doors with different capacities.


With their explosion-proof interiors, the EX series of laboratory refrigerators guarantees “working safely in laboratories” in accordance with BG-I 850-0. According to this, interiors in which dangerous, explosive atmospheres can develop, for example through deposited fl ammable liquids, must be explosion-proof. The body is made of sturdy sheet steel housing with impact and jolt-resistant powder coating. The EX series also achieves high energy effi ciency. The durable interior is made of high-strength white plastic (PS). The door is lockable. Sealing is ensured by an all-round magnetic gasket. The temperature is continuously adjustable from 1 to 15 °C and is constantly controlled by a room thermostat. Here, too, a digital temperature display shows the interior temperature. The powerful fan ensures even temperature distribution, including a stop function when the door is opened.

New engine air control system raises sustainability in the laboratory

Laboratories play a pivotal role in fuel testing, scientifi c research, innovation, and problem-solving across diverse fi elds. However, their extensive use of energy, materials, and consumables has raised concerns about their environmental impact. In recent years, there has been a growing emphasis on incorporating sustainable practices into laboratory operations, including the development of environmentally friendly ways of conserving natural resources.


CFR Engines Inc. is committed to sustainability and has identifi ed ways to improve the usage of natural water that is used in the recirculating system to cool the engine. In most cases, laboratories are utilising potable water with wastage of 5-6 litres per minute or on average – 2400 L per 8-hour shift – per engine. Implementing water


reduction strategies, such as implementing an integrated water recirculating system, would substantially decrease the environmental burden.


CFR is pleased to announce the new Closed-Loop EACS (Engine Air Control System), an integrated recirculating system that functions the same as the traditional EACS, without the need for water. This sustainability system interfaces with CFR’s XCP®


TECHNOLOGY for ease of management


and effi ciency. CFR’s most recent technology advancement furthers our commitment to creating a more environmentally sustainable product, allowing CFR users to conserve water wastage.


Environmental sustainability is no longer an option; it is a responsibility that laboratories must embrace, as well as manufacturers alike. By focusing on energy effi ciency, waste reduction, digitalisation, and responsible practices, laboratories can improve their environmental impact and contribute to a more sustainable future. Embracing these improvements not only benefi ts the planet, it also fosters a culture of responsible innovation in the scientifi c community.

For More Info, email: email:


Restek soil gas samplers are designed for simplicity, reliability, and fl exibility, so you can maximise data accuracy while minimising time, expense, and user error. The rugged, unibody design has fewer connections, so it’s quick and easy to set up and has fewer places where leaks could occur compared to typical samplers. The all- stainless-steel construction makes cleaning simple and means no contamination from degrading O-rings.


Samplers are ship leak tested (1 x 10-6 mL/sec) and ready to use to reduce your equipment prep time. In addition, all units are individually laser etched with a serial number and fl ow rate, so there’s no more guesswork from lost tags or labels.

The Determination of Mercury and the Hydride Elements in Seawater Costal and seawater matrices are considered some of the


most diffi cult sample types to analyse because of the often ultra-trace concentrations of target analytes, as well as the high total dissolved solids (TDS) that are present.


There are matrix and spectral interferences that analytical challenges using the common ICP-MS approach as the high TDS can lead to salt precipitation within the nebuliser, torch and cones. This is normally addressed by diluting the sample, but this has the undesired consequence of diluting the already ultra-trace concentration of Hg, As and Se making accurate and precise analysis very diffi cult.


Elevated concentrations of sodium, magnesium and chloride, form polyatomic spectral interferences making the determination of elements, such as As and Se, more complicated (often addressed by employing a collision gas cell to try and overcome these interferences).


The employment of PS Analytical instruments, the Millennium Merlin 1631 (for Hg) and the Millennium Excalibur (for As and Se) for seawater analysis are useful as the systems are not subject the interferences by either high TDS or polyatomic spectral issues.


Millennium Merlin 1631


These systems offer excellent sensitivity (in the ppt range), wide linear working ranges, ease of use and rapid return on investment.


The analysers also allow the determination of these analysts in other environmental matrices; such as drinking water, wastewater, soils, sediments and sludges.


Extending the capability still further into Speciation studies of these elements is also possible with the employment of the Modular Interface.
