LAUDA extends its portfolio with high-quality stills with the ‘GFL Technology’ quality mark
LAUDA, the world market leader for constant temperature equipment and systems for precise temperature generation, has extended its laboratory technology product range with the LAUDA Puridest stills product line. The devices with the 'GFL Technology' quality mark produce an ultra-pure, low-gas, sterile and pyrogen-free distillate with very low conductivity. Puridest stills are used in bacteriological and medical sample preparation and also in the preparation of cell and tissue cultures. They are also used for cleaning and sterilization processes, buffer solutions and microbiological and analytical applications. The distillate complies with the DAB regulations and the specifications of international pharmacopoeias. LAUDA Puridest stills also distill raw water of lower quality, separate pollutants, and reliably kill germs such as bacteria and viruses.
Low-maintenance and easy to use
LAUDA Puridest stills are available throughout the world in four high-performance product lines with 14 single- or two-stage model variants in the form of stainless steel or glass stills. Depending on the model, the devices are equipped with a storage tank and produce 2 to 12 liters of distillate per hour with conductivities down to below 1.6 µS/cm. Apart from their reliability and extremely long service life, LAUDA Puridest stills are characterized by their simple handling in the daily work in the laboratory. The stills are extremely easy to commission and operate. The ultra-pure water can be extracted directly after connection to the raw water and power supply. The devices are maintenance-free, because the glass stills automatically remove pollutants.
LAUDA Puridest stills with the "GFL Technology" quality mark
Decades of experience and technical development have set the standard: LAUDA Puridest stills are developed and manufactured by LAUDA-GFL. The company has been a member of the LAUDA group since December 31st, 2018 and is known throughout the world as a premium manufacturer of reliable laboratory technology. The use of the "GFL Technology" quality mark means that LAUDA is continuing the tradition of the GFL brand, which has been renowned for its quality and reliability in laboratories worldwide for more than 50 years.
Pure water: The Art of Distillation
Distillation is an effective and reliable way of producing pure water. The distinctive feature of distillation is that it only requires the input of energy. Compared with other auxiliary materials, such as absorbents or solvents, energy has the major advantage that it can be easily supplied to a system and removed again. As a result, stills require minimum maintenance. They are maintenance-free apart from regular cleaning. Distilled water, also referred to as aqua dest (lat. aqua destillata), is produced when steam condenses. This "pure water" is approx. 99.5 percent free of salts, organic substances, microorganisms, pyrogens and bacteria.
World market leader expands its portfolio with reliable shakers with "GFL Technology"
LAUDA, the world market leader for constant temperature equipment and systems, is expanding its product range of reliable laboratory devices for a wide spectrum of applications with the new Varioshake shakers. The LAUDA Varioshake product line comprises ten shakers in three sizes with five different shaking motions, as well as three shaking incubators in three sizes with a circular motion. Like the new LAUDA Hydro water baths, the Varioshake shakers feature “GFL Technology” and represent the many years of experience and outstanding quality of premium manufacturer GFL Gesellschaft für Labortechnik mbH, which became part of the LAUDA Group at the end of 2018. Equipped with modern LAUDA design and excellent performance data, the new GFL Technology laboratory devices stand for premium quality and precision.
LAUDA Varioshake: Shakers for reliable continuous operation

We will complete the reorganization in the course of this year."
Precise temperature control from LAUDA makes an important contribution to the fight against the corona virus
The corona virus is changing our daily life and work in a way never before seen. Since the restrictions in public life currently continue to be largely maintained and can only be eased gradually, the pressure on global medical research to develop drugs, therapies and ultimately a vaccine against this novel virus is increasing. LAUDA, as a manufacturer of temperature control units and systems as well as laboratory equipment, contributes to the solution in dealing with COVID-19. As a long-standing supplier of professional temperature control technology with over 60 years of experience, LAUDA equips laboratories all over the world with highly accurate and reliable temperature control and laboratory technology. In times of the Corona Pandemic, an even more important part of LAUDA's expertise is found in the area of pharmaceutical production of active ingredients.
LAUDA temperature control units support companies in the chemical and pharmaceutical industry, for example in the commercial production of pharmaceutically and biotechnologically produced active ingredients - this becomes important, for example, in the production of a vaccine against the coronavirus in large quantities. An important step in this process is the temperature control of bioreactors. Here, microorganisms are cultivated under the best possible conditions, for example in the range of body temperature to 37 to 38 °C, and then suddenly cooled down. "In the field of bioproduction, we have been supplying all well-known customers for years. Especially our Integral process thermostats and the Variocool recirculating coolers with additional heating have become a kind of gold standard in the temperature control of bioreactors," explains Dr. Gunther Wobser, President and CEO of LAUDA.
For the mass production of a possible vaccine or supporting medication, the industrial division of LAUDA develops heating and cooling lyses for scale-up processes. These include process cooling systems for so-called "Freeze & Thaw" processes, in which active ingredients are deep-frozen in large tanks and shipped for further processing. "We are currently receiving enquiries from major technology companies in the USA who are using our industrial cooling systems for research on COVID-19," says Dr. Marc Stricker, the COO responsible for this area.
In addition to production, the storage of active ingredients plays an important role in combating the pandemic. LAUDA cryogenic equipment is used, for example, in the pharmaceutical industry for the production of vaccines and medications in order to store samples safely and over a long period of time.
LAUDA also offers solutions in the area of preparatory steps: "In the area of laboratory technology, we are currently receiving an increasing number of enquiries about LAUDA-GFL stills", explains Dr. Gunther Wobser. The distillation apparatuses of the youngest LAUDA subsidiary are used for the production of purified water for the manufacture of disinfectants as well as for the supply of autoclaves for sterilisation/autoclaving, e.g. of surgical instruments, components or tubes of respirators. So-called overhead shakers also help in the fight against coronavirus - the shakers are used to produce solutions for test kits for the extraction of DNA and RNA from a variety of sample materials such as serum, plasma, oropharyngeal or nasopharyngeal swabs (mouth, throat or nose) or other respiratory samples.
However, LAUDA's contribution does not end with its products and services. The company has also offered its support to the Corona Task Force for Medical Technology of the state of Baden-Württemberg, as well as to the well-known medical technology company Dräger in the production of urgently required medical devices. LAUDA also helped Corona helpers of the Main-Tauber Kreis with donations in their solidarity against the consequences of CO-VID-19: "We take the virus very seriously in our own company as well and have initiated strict rules and safety measures to protect the health of our employees and at the same time ensure the availability of our temperature control units worldwide," says Dr. Gunther Wobser. "Fortunately, we can still guarantee this at present. All of our employees are working flat out, either on site or from their home offices, to deliver first-class quality under the given restrictions for those who are urgently dependent on our products in the fight against COVID-19," adds CFO Dr. Mario Englert. "We are proud to be able to contribute to the solution of the Corona crisis with our daily work".
LAUDA intensifies involvement with innovative start-up watttron
The LAUDA DR. R. WOBSER GmbH & Co. KG, the world market leader for precise temperature control, has renewed its support for the Saxon technology start-up watttron. Together with other renowned investors, LAUDA is providing fresh capital of EUR 3.4 million in addition to expertise. LAUDA is thus underlining the importance of the successful cooperation with the young company from Freital near Dresden, which began in 2018. The multi-award-winning start-up company develops and manufactures intelligent heating systems that are able to heat with pinpoint accuracy. This is particularly important in the packaging industry, as the innovative process can save energy and material. Together with LAUDA, marketing opportunities in the fields of analysis, bio and laboratory technology and on the North American market are being worked on. In addition, both companies are working on a prototype that is not only capable of heating with pixel accuracy, but also of cooling.
With the current financing round, watttron aims to accelerate its own development, gain new partners on a global level and open up new industries such as biotechnology, chemistry or 3D electronics. LAUDA as a partner firmly believes in the success of the young company and is convinced of the joint partnership: »We have been watttron's cooperation partner for around two years because we have already seen and actively support the benefits of the patented heating technology beyond the packaging market in 2018«, says Dr. Gunther Wobser, President and CEO of LAUDA. »The positive development of recent years has confirmed our decision to continue investing in watttron.«
LAUDA Introduces New Thermoelectric Process Thermostats
Thermoelectric process thermostats, which are used in the temperature control of etching processes in the semiconductor industry, have been a permanent feature of LAUDA’s comprehensive portfolio since its acquisition by Noah Precision (now LAUDA-Noah) in 2014. Now the global market leader has fully revised and expanded the former POU product line with the new “Semistat” series.
The new LAUDA Semistat product line comprises three models: LAUDA's Semistat S 1200 is an affordable entry-level device that offers an even smaller footprint than its predecessor – with the same cooling output of 1.2 kW at 20°C. Meanwhile, the newly developed Semistat S 2400 retains the mechanical and hydraulic structure of the product line. The process thermostat also incorporates the latest innovations from the thermoelectrics sector, such as the latest generation of high-performance Peltier elements, which guarantees a higher power density and greater reliability. With the Semistat 4400, LAUDA has brought a whole new performance class with 4.4 kW cooling output to market. This process thermostat is specially designed for applications using 300 mm wafers with a high cooling output requirement at low temperatures.
Thermoelectric process thermostats for the semiconductor industry from -20 to 90 °C
Semistat process thermostats have been optimized for precision temperature control in plasma etching applications in the semiconductor industry. Defined areas are removed from the surface of the wafers during the etching process. A dynamic temperature controller keeps the wafer chucks located inside the plasma etching chamber at a constant temperature, to prevent temperature drift. The constant temperature is crucial in maintaining a stable etching profile and producing a high-quality surface. Peltier technology realizes the two main advantages of Semistat thermostats: energy and space savings combined with maximum long-term operational stability.
The new process thermostats are extremely energy-efficient because they only control the temperature and consume energy when there is a need to regulate the temperature inside the etching chamber. Since the Peltier element is the only component used for heating and cooling, it is possible to minimize the space requirements of the thermostat. The compact design and optional underfloor installation ensure that minimal space is occupied in the cost-intensive cleanroom. A small internal fluid volume and short hose connections from the device to the application mean that less energy is required to control the fluid temperature. The low volume of the temperature control fluid, in particular, allows rapid temperature changes. Semistat temperature control systems use up to 90 percent less energy than compressor-based systems.
Like its established predecessor, the Semitat product line has a working temperature range of -20 to 90°C and offers a high temperature stability of ±0.1 K. With cooling outputs from 1.2 to 4.4 kW, the water-cooled devices can be used in combination with a large variety of chamber and platform models.
