Antibiotic nanoparticles fight drug-resistant bacteria

Antibiotic resistance is a growing problem, especially among a type of bacteria that are classified as “Gram-negative.” These bacteria have two cell membranes, making it more difficult for drugs to penetrate and kill the cells.   READ MORE

Experts get gold nanoparticles using mimosa that fight antibiotic-resistant bacteria

MOSCOW, July 12. /TASS/ An international research team from Mexico, India, and the Siberian Federal University (SFU) have mastered the synthesis of gold-containing nanoparticles by using bacteria residing inside the sensitive plant (Mimosa pudica), the press office said.   The compounds obtained show marked antibacterial properties. According to the researchers who initiated the study, the… Read more »

Dutch scientists discover favorable conditions for growth of Legionella bacteria

The bacteria that cause Legionnaire’s disease grow well in warm tap water installations with ample dissolved organic matter–conditions that support the growth of biofilms. The research is published January 6th in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.   READ MORE

More than a 100 different parameters available. Activation of add-on parameters is possible even after purchase. Powerful PC-software and app with free cloud service. Creating reports and dosage recommendations by just a click, using your individual water treatment chemicals.

HuwaSan TR50 Silver Stabilised Hydrogen Peroxide

HuwaSan TR50 is a commercial water disinfectant and biocide designed for shock disinfection or constant dosing. HuwaSan TR50 kills legionella bacteria and in addition removes biofilm. It is safer to use than chlorine as the disinfection breakdown products are oxygen and water. Independent testing shows that HuwaSan TR50 provides a very wide spectrum of biocidal activity against bacteria, viruses, spores, fungi, amoebae (such as amoeba acanthus which can act as a host to legionella bacteria) and algae. Use disinfectants safely. Always read the label and product information before use.

MC1+ Protector

Formulated to prevent wear and tear and the resulting debris, MC1+ stops magnetite and other deposits forming. As it does this, it protects the central heating, keeping the boiler working efficiently and helping to ensure the system lasts for longer.

MM2050 - PT100 Thermometer

Four/three/two wire measurement, Max/min functions, Hold function, Dual display, °C/°F/°A selectable, Simultaneous display of real time and max/min/hold measurement, Self calibrating.

MD610 Photometer

The MD610 gives you a mobile device in a modern design with the analytical features of a laboratory photometer. All important water analysis parameters from A(luminium) to Z(inc) are covered. Combined with the high precision of Lovibond® reagents, a reliable and quick analysis of water samples is guaranteed. Reagent tablets, powder reagents, liquid reagents, or cuvette tests are used depending on the method.

Armitage Shanks Markwik 21


(TB H2a) an integral thermostatic bib mixer tap, single long lever mixer. Single flow fixed horizontal nozzle, sequential operation. Sequential operation ensures both hot and cold supply are purged on each use, long lever gives precise control. Insulated technology keeps the ‘hot’ side of the mixer at a safe surface temperature.

AS Shower chrome

AS Shower chrome

Legionnaires‘ disease is usually spread by the breathing in of water vapour containing Legionella bacteria which is then deposited on the lungs. The bacteria thrives in water temperatures between 25 and 45°C and so showers by their very nature create an ideal environment for the bacteria to spread. The AS SHOWER chrome filter provides reliable and immediate protection against Legionella, removing bacteria at the point of use, allowing users to shower safely.
