Particle size measurement instruments typically employ deionized or even untreated water as a suspen (more)sion medium for particle dispersion during analysis. Usually, this water contains undesirable levels of dissolved gases, most often those commonly present in the atmosphere. During analysis, these gases can come out of solution, forming minute bubbles that can have important effects on the analytical results. Regardless of the relative size of the bubbles, their presence distorts the reported distribution of sizes; it also degrades the repeatability of analyses. The more powerful the analyzer, the more pronounced these effects can be. When using a highly sensitive instrument such as the Micromeritics Saturn DigiSizer, removal of the dissolved gases (that subsequently lead to bubble formation) is therefore extremely desirable for obtaining the most accurate particle size data possible. The Micromeritics AquaPrep is a highly-effective system for freeing water of dissolved gases for use with the Saturn DigiSizer. The AquaPrep recirculates water through a hydrophobic capsule consisting of many thin-walled capillaries. A vacuum pump provides low pressure on the outside of the capillaries, causing a diffusion of dissolved air from the water through the capillary walls and into the vacuum pump. The air removed from the water is subsequently exhausted through a small tube at the front of the instrument, which is connected to a bubbler-type apparatus for performance monitoring. During typical operation, the AquaPrep can prepare approximately 5 liters of water for analysis in less than 2 hours. Because air bubbles scatter light as do particles, the AquaPrep enhances even further the high-accuracy analysis of small particles. Its compact, rugged, and reliable design make it ideal for use in a wide variety of aqueous particlesizing applications.

MAGNETIC STIRRER MST DIGITAL - VELP The white surface of the MST instrument facilitates the detectio (more)n of the color change of a solution, making it suitable for many applications in the microbiological and biochemical fields and for microtitration. MST also does not overheat and maintains a low temperature even after hours of continuous use. This feature makes it ideal for BOD analysis. The compact design of MST also makes it particularly suitable for all laboratories that have limited space. Stirring speed always under control MST Digital guarantees maximum simplicity in setting and controlling the stirring speed. It is possible to go from 80 to 1500 rpm with 10 rpm steps. SpeedServo™ technology also ensures constant speed with feedback to changes in viscosity. Unsupervised and programmable agitation Thanks to its integrated timer, the MST Digital allows you to program the stirring time allowing the automatic shutdown of the stirrer. It is also possible to program the rotation inversion after certain time intervals. Small and mighty - Digital display that simplifies the setting of the stirring speed - Integrated timer and programmable automatic shutdown - Reversal of the stirring direction at programmable intervals - SpeedServoTM ensures constant speed even when the viscosity varies (counter-reaction) - Stirring speed adjustment up to 1500 rpm Robust and compact - Structure in technopolymer resistant to chemical agents - Equipped with a brushless motor - White surface that favors the detection of color variations - Designed to last over time - Accepts a stirring volume of up to 5 liters Versatile - Stays cold even after hours of continuous use - Ideal for applications such as Microtitration, BOD, Microbiology and Biochemistry - Excellent speed regulation even at low rpm Technical features: Speed ​​regulation step: 10 rpm Speed ​​control: excellent even at low revs Feedback: Constant speed Reverse direction: 5 to 900 seconds Stirring system: PCM magnet; brushless motor

PELTIER LABORATORY INCUBATORS ILP SMART POL-EKO ILP - REFRIGERATION WITH PELTIER TECHNOLOGY ILP incu (more)bators are innovative and ecological instruments, which use the Peltier system to cool the internal chamber. They maintain a constant temperature from 0°C to 70°C, being able to drop to a maximum of 20°C below the ambient temperature. Cooling with Peltier technology gives these instruments multiple advantages: they are silent, vibration-free, precise and ecological.

The strengths of Peltier technology are the scalability of the cooling elements, the possibility of operating anywhere, its reliability and precise power control. Furthermore, the Peltier elements work without moving parts and therefore without vibrations or noise. One of the main advantages compared to traditional compressors is that no flammable or environmentally harmful refrigerants are used and in general, the whole system is much simpler, avoiding breakdowns. To find out more, we recommend the Wikipedia page Thermoelectric cooler. In particular, for incubation, Peltier cells bring several advantages: Zero vibration - Through the use of Peltier cells, the vibrations previously generated by the compressor are eliminated. Minimal fluctuation and variation: excellent fluctuation, variation and short time to reach the set temperature. Lighter design with more space: Peltier cooling system reduces the overall size of the instrument and its weight. Ecological: Peltier technology is simple and does not use substances harmful to the environment. Below are simple operating diagrams of the ILP incubators during cooling and heating.
