LAUDA Puridest PD 8 R Water Distiller, Single-column Distiller, L003015
The LAUDA Puridest PD 8 R water distiller is a highly advanced thermal system solution for the fully automated production of high-purity, sterile and pyrogen-free ultrapure water (mono-distillate) in clinical, pharmaceutical and university laboratory settings. In demanding analytical processes, reagent preparation or microbiological cell culture applications, the consistent removal of inorganic salts, organic impurities and microbial organisms is the primary criterion for gently eliminating interference effects in instrumental analyses. This fully automatic compact system delivers an excellent distillate conductivity of approx. 2.3 µS/cm at 25 °C and, with a continuous production rate of 8 litres per hour, ensures a self-sufficient supply of ultrapure water. For laboratory managers and procurement officers, this integrated system architecture offers the ideal combination of on-demand media storage and exceptional process reliability in accordance with stringent GLP and GMP guidelines, thanks to the generous 16-litre storage tank. Thermodynamic separation process and ultrapure water quality The distillation-based operating principle of the Mono distillation unit is founded on the classic, physically unrivalled phase transition of raw water into the vapour phase, followed by condensation. Through boiling in the precisely temperature-controlled distillation flask, non-volatile impurities, heavy metal ions and particulate matter are retained in the sump. A key fluid dynamics-related quality feature is the integrated CO₂ degassing port on the condenser, which reliably separates volatile acidic gases such as carbon dioxide to prevent any subsequent drop in the pH of the distillate in the storage tank. The integrated condenser is installed as a robust cooling coil directly within the storage tank and guarantees highly efficient enthalpy exchange with minimal thermal losses. Cooling efficiency and automated resource management The thermodynamic kinetics of the LAUDA Puridest PD 8 R are characterised by intelligent, energy-optimised media management. The cooling water used for condensation – which is heated in a way that is gentle on the material – is routed directly to feed the distillation flask (boiler). This energy-efficient circulation drastically reduces the required nominal thermal output of the 6 kW tubular heating elements and minimises the overall CO₂ footprint of laboratory operations. To conserve valuable raw water resources, an integrated solenoid valve controls the water supply fully automatically: once the storage tank is completely filled, the system instantly shuts off the cooling water supply, thereby avoiding unnecessary idle consumption whilst preserving the material. Materials Science System Integrity and Sensors The physical boundaries of the apparatus are defined by a double-walled, powder-coated housing made of galvanised sheet steel, which offers outstanding thermal insulation and mechanical resilience. All functional components in contact with samples and steam – such as tubular heating elements, the distillation flask, the storage tank and the condenser – are made of high-purity, stainless steel. This material-science-based quality feature prevents metallic cross-contamination and facilitates cyclic descaling via the easily accessible distillation flask. Cybernetic monitoring is carried out via an electronic contamination control system with automatic distillation stop and visual cleaning instructions, as well as a thermostatic low-water safety device (dry-run protection). Once distillate has been drawn off via the ergonomic tap with integrated continuous and intermittent settings, an electronic level sensor triggers the immediate, fully automatic refilling of the storage tank.

LAUDA Puridest PD 4 G Water Distillation Apparatus, Glass Distillation Apparatus, L003018
The LAUDA Puridest PD 4 G water distillation unit is a specialised, cryogenic and thermotechnically advanced laboratory system solution for the fully automated production of high-purity, sterile and germ-free ultrapure water (mono-distillate). In demanding physico-chemical and medical laboratory applications such as sample dilution, reagent preparation or instrumental analysis, absolute purity of the source medium is essential to rule out process-related artefacts and microbiological contamination. The compact system delivers a constant output of approximately 4 litres per hour with an excellent conductivity of 2.2 µS/cm at 25 °C. For laboratory managers and industrial procurement departments, this glass distillation apparatus offers the highest level of validity and operational reliability, as it can be commissioned without specialist staff and is optimised for the treatment of ordinary raw water. Thermodynamic phase transition and visible ultra-pure water quality The distillation-based purification principle of this fully automatic unit is based on the precise thermal evaporation and subsequent recondensation of the medium. An outstanding material-related feature is that the evaporator, condensers and overflow pipes are manufactured entirely from high-purity DURAN / borosilicate glass 3.3. This material-science specification guarantees absolute inertness towards both the gaseous and liquid phases, thereby permanently ruling out metallic cross-contamination whilst preserving the integrity of the materials. Thanks to an easily removable, shatterproof and non-fogging front pane, the entire distillation process can be visually monitored. The integrated condensers are also fitted with a drip-resistant vapour guide (drip protection) and can be sterilised directly within the system via the targeted vapour guide. Quartz-sheathed heating elements and highly efficient energy recovery The thermal heating concept of the LAUDA Puridest PD 4 G is implemented using high-performance electric heating rods fitted with a high-quality quartz glass sheath. This sheath not only minimises abrasive wear caused by limescale deposits in the boiler but also ensures highly efficient heat radiation to the surrounding fluid. With a heating output of 3 kW, the system ensures extremely short pull-down times to the boiling point. To drastically reduce operating costs, the system utilises an intelligent energy recovery concept: the cooling water used to condense the steam – which is heated in a way that is gentle on the material – is fed directly into the evaporator boiler, significantly minimising overall energy consumption. Cybernetic contamination monitor and automated media management To ensure seamlessly monitored quality management, the unit is equipped with a process-reliable cybernetic monitoring system. An integrated electronic contamination monitor continuously measures the status inside the evaporator; in the event of critical contamination levels, it automatically initiates a water change to thoroughly flush and clean the boiler. An integrated solenoid valve controls the water supply in a way that is gentle on the material and blocks the inflow once the target state is reached, thereby reliably preventing unnecessary wastage of cooling water resources (approx. 1.2 l/min). An electronic level monitoring system and a dual water shortage safety feature instantly disconnect the system from the power supply should the raw water supply fail, enabling self-sufficient and unattended continuous operation in the laboratory.

LAUDA Puridest PD 4 D Water Distiller, Double-distillation unit, L003021
The LAUDA Puridest PD 4 D water distillation unit represents a highly advanced, thermal system solution for the fully automated production of high-purity, sterile and pyrogen-free double distillate (bi-distillate) in clinical, pharmaceutical and university laboratory settings. In the most demanding analytical processes, such as cell culture inoculation, molecular biological PCR preparation or instrumental trace analysis, the uncompromising removal of inorganic and organic impurities is the primary criterion for physically ruling out process-related artefacts. The mechatronic system operates on the principle of two-stage cascade distillation: The mono-distillate obtained in the first stage is fed directly into the second evaporation stage. This dual phase transition guarantees outstanding ultrapure water quality with a minimum conductivity of approx. 1.6 µS/cm at 25 °C, thereby ensuring the highest level of SOP compliance and validity in laboratory operations. Two-stage cascade distillation for maximum conductivity precision The distillation-based purification principle of this fully automatic system is based on two thermal evaporation cycles connected in series. Boiling in the primary distillation flask causes non-volatile impurities, heavy metal ions and particulate matter to be retained in the sump. A key fluid dynamics feature is the integrated CO₂ degassing port on the condenser, which reliably separates volatile acidic gases such as carbon dioxide to prevent any subsequent reduction in the pH of the distillate within the media stream. The heating capacity of 7.0 kW ensures highly efficient evaporation rates and a continuous production rate of 4 l/h. Hybrid material architecture and contamination-free withdrawal The choice of materials for the PD 4 D combines the durability of robust metal with the absolute inertness of high-quality glass. Whilst the condenser (cooling coil) and the first-stage distillation flask are made from high-purity, stainless steel, the second-stage condenser and the integrated splash guard are made from DURAN borosilicate glass 3.3. This hybrid architectural design, based on materials science, permanently prevents metallic abrasion and ion carry-over during the final purification stage, whilst being gentle on the materials. To ensure maximum flexibility in day-to-day laboratory work, the system allows for the separate collection of both grades: the mono-distillate can be collected via a precision shut-off valve made of borosilicate glass with a PTFE stem, whilst the ultra-pure bi-distillate flows through a free outlet, which is protected from atmospheric contamination by an integrated dust protection bell. Cybernetic process monitoring and intelligent resource management To ensure seamless quality management, the bi-distillation apparatus is equipped with an intelligent, cybernetic monitoring system. An electronic contamination monitor continuously measures the status inside the distillation flask; in the event of a critical load, the system automatically halts the process and displays a visual cleaning prompt, which significantly extends the service life of the quartz-clad heating elements.

LAUDA Puridest PD 8 D Water Distiller, Double-distillation unit, L003022
The LAUDA Puridest PD 8 D water distiller represents a highly advanced, thermal system solution for the fully automated production of high-purity, sterile and pyrogen-free double distillate (bi-distillate) in clinical, pharmaceutical and university laboratory settings. In the most demanding analytical processes, such as cell culture inoculation, molecular biological PCR preparation or instrumental trace analysis, the uncompromising removal of inorganic and organic impurities is the primary criterion for physically ruling out process-related artefacts. The mechatronic system operates on the principle of two-stage cascade distillation: The mono-distillate obtained in the first stage is fed directly into the second evaporation stage. This dual phase transition guarantees outstanding ultrapure water quality with a minimum conductivity of approx. 1.6 µS/cm at 25 °C, thereby ensuring the highest level of SOP compliance and validity in laboratory operations. Two-stage cascade distillation for maximum conductivity precision The distillation-based purification principle of this fully automatic system is based on two thermal evaporation cycles connected in series. Boiling in the primary distillation flask causes non-volatile impurities, heavy metal ions and particulate matter to be retained in the sump. A key fluid dynamics feature is the integrated CO₂ degassing port on the condenser, which reliably separates volatile acidic gases such as carbon dioxide to prevent any subsequent reduction in the pH of the distillate within the media stream. The enormous heating capacity of 11.5 kW ensures highly efficient evaporation rates and a continuous production rate of 8 l/h. Hybrid material architecture and contamination-free withdrawal The choice of materials for the PD 8 D combines the durability of robust metal with the absolute inertness of high-quality glass. Whilst the condenser (cooling coil) and the first-stage distillation flask are made from high-purity, stainless steel, the second-stage condenser and the integrated splash guard are made from DURAN borosilicate glass 3.3. This hybrid material architecture, based on materials science, permanently prevents metallic abrasion and ion carry-over during the final purification phase, whilst being gentle on the material. To ensure maximum flexibility in day-to-day laboratory work, the system allows for the separate collection of both grades: the mono-distillate can be collected via a precision shut-off valve made of borosilicate glass with a PTFE stem, whilst the ultra-pure bi-distillate flows through a free outlet, which is protected from atmospheric contamination by an integrated dust protection bell. Cybernetic process monitoring and intelligent resource management To ensure seamless quality management, the bi-distillation apparatus is equipped with an intelligent, cybernetic monitoring system. An electronic contamination monitor continuously measures the status inside the distillation flask; in the event of a critical load, the system automatically halts the process and displays a visual cleaning prompt, which significantly extends the service life of the quartz-clad heating elements. An integrated solenoid valve controls the water supply in a way that minimises wear on the equipment and triggers an automatic shut-off once the target condition is reached, thereby preventing unnecessary wastage of cooling water resources. A dual water shortage safety feature reliably protects the unit against running dry, ensuring self-sufficient and absolutely safe continuous operation.

LAUDA Puridest PD 4 DG Water Distiller, Glass Double-Distillation Apparatus, L003024
The LAUDA Puridest PD 4 DG water distillation unit is a specialised thermal system solution for the fully automated production of high-purity, sterile and pyrogen-free double distillate (bi-distillate) in clinical, pharmaceutical and chemical laboratory settings. In the most demanding analytical processes, such as cell culture inoculation, molecular biological PCR preparation or instrumental trace analysis, the uncompromising elimination of inorganic and organic impurities is the primary criterion for physically ruling out process-related artefacts. The compact system operates on the principle of two-stage cascade distillation and completely avoids the use of metallic surfaces during the critical phases. This dual phase transition guarantees outstanding ultrapure water quality with a minimum conductivity of approx. 1.6 uS/cm at 25 °C, thereby ensuring the highest level of SOP compliance and validity in laboratory operations. Two-stage all-glass cascade distillation for maximum purity The distillation-based purification principle of this fully automatic unit is based on two thermal evaporation cycles connected in series. An outstanding material-related feature is the fact that the evaporators, condensers and overflow pipes are manufactured entirely from high-purity DURAN borosilicate glass 3.3. This material-science specification guarantees absolute inertness towards both the gas and liquid phases, thereby permanently and gently ruling out metallic abrasion and ion carry-over in the final purification phase. A key fluid dynamics-related quality feature is the integrated CO₂ degassing port on the condenser, which reliably separates volatile acidic gases such as carbon dioxide to prevent any subsequent reduction in the pH of the distillate within the media stream. The heating capacity ensures highly efficient evaporation rates and a continuous production rate of 4 l/h. Quartz-sheathed heating elements and optimised energy management The thermal heating concept of the LAUDA Puridest PD 4 DG is implemented using high-performance electric heating rods fitted with a high-quality quartz glass sheath. This sheath not only minimises abrasive wear caused by limescale deposits in the boiler, but also ensures highly efficient heat radiation to the surrounding fluid. With a heating capacity of 5.8 kW, the system ensures extremely short pull-down times to the boiling point. To drastically reduce operating costs, the system utilises an intelligent energy recovery concept: the cooling water used to condense the steam – which is heated in a way that is gentle on the material – is fed directly into the evaporative boiler, thereby significantly minimising overall energy consumption. Cybernetic monitoring and process-reliable media management To ensure seamlessly monitored quality management, the unit is equipped with a process-reliable cybernetic monitoring system. An integrated electronic contamination monitor continuously measures the status inside the evaporator; in the event of a critical load, it automatically initiates a water change to thoroughly flush and clean the boiler. An integrated solenoid valve controls the water supply in a way that is gentle on the material and blocks the inflow once the target state is reached, thereby reliably preventing unnecessary wastage of cooling water resources. An electronic level monitoring system and a dual water shortage safety feature instantly disconnect the system from the mains supply in the event of a failure in the raw water supply, enabling self-sufficient and unattended continuous operation in the laboratory. Thanks to an easily removable, shatterproof and non-fogging front pane, the entire distillation process can be visually monitored.
