![]() Expect outstanding precision and reliability paired with intuitive operation plus double overtemperature protection including visual alarm. Temperature, air flap position and fan speed remain at a constant value throughout your process? You have no need for ramp programming or loops? You only have to incubate samples at the same temperature and require neither multiple overtemperature protection nor a technically complex alarm system? Then the functions of Memmert's model variant SingleDISPLAY will be perfect for your application. Non-Programmable (SingleDISPLAY) for standard applications Since our unique all-round surface heating is optimally geared to both natural convection and forced air circulation, the fan can be switched off entirely for sensitive samples and for samples which may not be exposed to air turbulence. To guarantee optimum air circulation in the incubator chamber even when it is fully loaded, both model variants SingleDISPLAY and TwinDISPLAY are available with an adjustable air fan. Often a minimum of 2-3 RH sensors are placed throughout the chamber and the same is valid for CO2 measurement.Memmert incubator – a gentle force in the laboratory With biological incubators the temperature validation is similar to above whereas the number of relative humidity measuring points is dependent on the chamber design (the ability to circulate air typically performed by a fan). For example, the acceptance criteria for a standard incubator with a set point of +37☌, is that all measurements throughout the chamber do not individually differ by more than 2☌ and all measurements maintain temperature around 32☌ to 37☌. Even most standard incubators provide access port(s) the cable feed through could disturb the integrity of the chamber atmosphere. For larger chambers it is recommended to place 5 measuring points on a minimum of 3 layers or on each layer with sample readings every 1- 5 minutes for 24, 48 or 72 hours.Įllab’s wireless loggers are ideal for such qualifications. During OQ these are fixed directly on the shelves in an empty chamber and during PQ they are placed into loaded samples. The typical number of measuring points is 5 (4 corners + center) on the lower and top shelf. The OQ also contains information about the calibration of measuring equipment and defines the location of the thermocouples and /or data loggers in the incubator. The OQ consists of temperature mapping of the empty chamber and is performed to confirm that the empty chamber works within the specified limits throughout the chamber. In the OQ, the performance of the incubator and its operational procedure is verified. The IQ is conducted to demonstrate that the incubator is inspected and contains all the required parts to ensure functionality. ![]() Validation of an incubator consists of various steps regarding Installation Qualification (IQ), Operational Qualifications (OQ) and Performance Qualifications (PQ). ![]() The standard applies for cabinets and incubators with a working temperature range from -10☌ to 300☌ and includes shaking incubators. Furthermore, DIN 12880-2 specifies performance requirements and tests for heating cabinets and incubators in laboratories. Subpart D describes handling of equipment (that it shall be routinely calibrated, inspected or checked according to a written program designed to assure proper performance). The Current Good Manufacturing Practice for manufacturing, processing, packing or holding of drugs and Current Good Manufacturing Practice for finished pharmaceuticals is described in 21 CFR Parts 210 and 211.
