New Generation High-Torque and High-Speed Stirrers Introduced
Wiggens introduces the new generation of high-torque and high-speed overhead stirrers with the WB-3000, WB-1800, and WB-6000 series. These units are specifically designed for high torque applications and/or high speed applications where conventional stirrers reach their limit with regard to sample viscosity or speed requirements.
The Wiggens high-torque and high-speed stirrers feature a high resolution TFT display which can show not only the current speed and torque, but also the set speed, gear stage, controlling mode and timer settings. All stirrers come with a BLDC motor, which is highly beneficial to the durability of the product. In comparison to AC motors, BLDC motors are more quiet, robust and maintenance free. In addition, all stirrers employ a two stage gear transmission box for optimal processing of high torque at low speeds or lower torque at higher speeds. A special feature is the smart torque adjustment that enables the stirrer to maintain the set speed even if the viscosity of the sample changes during the stirring process. The latest chuck design makes impeller changes easy and guarantees that the impeller sits perfectly.
The housing is made of die-cast aluminium and features heat reduction fins, which contribute to keeping the unit cool in long-term applications. An RS-232 and RS-485 input as well as analogue control make all stirrers highly versatile and adoptable for different applications. Thus, they can be used as a stand-alone unit or, for instance, integrated in chemical reaction systems.
The Wiggens high-torque and high-speed series are also available as remotely controllable units, with the stirring and controlling box separated. This makes them an even better fit for integration in reaction systems where the controller is required to be in an easily reachable position.

42061pr@reply-direct.com Multifunctional Pump for Automated Dosing of Liquids
Systec Mediapump, the programmable multifunction pump for the manual or automated dosing of fluids from Systec GmbH, is available right now in a new and improved design. The performance of the electronically controlled peristaltic pump with its practical functionality and ease of operation speaks for itself.
The dosing volume can be set from 0.1 ml to 99,999.9 ml. The system works with an accuracy of ± 0.5%, ensuring reproducible results thanks to its automatic calibration. Individually parameterisable programs are available in addition to the simple manual filling process.
A robust precision roller mechanism ensures the highest possible dosing accuracy even at high flow rates exceeding 2,500 ml/min, with the special roller head ensuring a continuous fluid flow with minimum pulsation. The Systec Mediapump is also particularly suitable for filling petri dishes with hot and viscous media.
Thanks to its well thought out design, the Systec Mediapump can also be used as a component of automated processes. It offers a high degree of flexibility because different tube sets can be programmed and used reproducibly. A novel tube bed mechanism facilitates the task of changing the tube sets.
All the functions are clearly laid out on the touchscreen of the Systec Mediapump together with the permanent display of the different parameters. Different languages and colour settings can be selected via the touchscreen.
Features include: high quality industrial touch screen and smooth housing surfaces from stainless steel for effective wipe disinfection; reverse function prevents media from gelling in the tube set if the pump is out of use for longish periods; start and stop function can be operated either by hand or foot switch; fully flexible stand with holder for the discharge nozzle; easy to service modular construction and compact design; ideal for the use with the Systec Mediaprep media preparators.

PolyScience’s line of economical general purpose water baths combine exceptional temperature control with full- featured digital functionality and ease of operation. Designed to accommodate a wide variety of clinical and laboratory applications, these versatile water baths maintain bath temperatures from ambient +5° to 99°C with ±0.1° stability and ±0.2°C uniformity. They are available with 2, 5, 10, 20, or 28 litre single chamber reservoirs.
In addition to precise temperature control, PolyScience Water Baths feature a digital temperature readout that displays both the actual bath temperature and set point temperature simultaneously, three user-defined temperature preset buttons for the quick selection of frequently used temperature set points and an integrated timer. Bath temperature can be displayed in either °C or °F. For added operational convenience, all models include a steeply gabled tilting cover that accommodates glassware of varying heights and permits easy loading and removal of samples while allowing condensate to drain neatly back into the bath. A high-clearance lid is available as an accessory for larger flasks or bottles. Baths with a 10 litre or large reservoir are also equipped with a reservoir drain. All models come equipped with a diffuser tray.
