Memmert HPP110 Overview
The Memmert HPP110 is part of the manufacturer's HPP series of constant climate chambers, developed for laboratories requiring precise and reproducible temperature and humidity conditions.
Unlike conventional refrigerated incubators that rely on compressor-based refrigeration, the HPP110 uses thermoelectric Peltier elements to provide both heating and cooling.
This technology allows the chamber to maintain temperatures above or below ambient conditions without requiring a conventional refrigerant compressor.
The HPP110 also incorporates active humidification and dehumidification, enabling laboratories to establish specific temperature and relative-humidity conditions for stability studies and environmental testing.
The chamber provides approximately 108 liters of usable interior capacity, making it suitable for small and medium-sized sample batches, packaged products, laboratory vessels, and other materials.
A stainless steel interior provides durability and resistance to corrosion, while the insulated outer door helps maintain stable environmental conditions.
The inner glass observation door allows researchers to inspect samples without fully exposing the chamber to surrounding laboratory air.
The TwinDISPLAY ControlCOCKPIT provides intuitive access to temperature and humidity settings, operating programs, alarms, and system information.
These features make the HPP110 a practical choice for laboratories requiring advanced environmental control in a relatively compact footprint.
Common Applications
The Memmert HPP110 is suitable for pharmaceutical stability testing, product shelf-life evaluation, environmental simulation, material conditioning, and industrial quality-control procedures.
Pharmaceutical laboratories can use the chamber to evaluate drug substances, finished products, packaging materials, and other samples exposed to controlled temperature and humidity.
The HPP110's operating capabilities support commonly used stability-study conditions, including 25°C/60% RH and 40°C/75% RH, subject to appropriate qualification and verification.
Cosmetics manufacturers can use the chamber to evaluate formulation stability, packaging compatibility, and product performance under controlled environmental conditions.
Food laboratories may use it for shelf-life testing, moisture-sensitivity studies, and evaluation of packaged products.
Industrial research facilities can use the HPP110 for material conditioning, accelerated aging, and environmental simulation.
The chamber is also suitable for selected biological research applications requiring controlled temperature and humidity rather than CO₂ regulation.
For laboratories requiring additional temperature-controlled equipment, the HPP110 complements laboratory refrigerators, laboratory freezers, and ultra-low temperature freezers.
Additional equipment is available through American Instrument Exchange's selection of used and refurbished laboratory incubators.
Ideal Laboratory Environments
The Memmert HPP110 is particularly well suited for pharmaceutical research laboratories, biotechnology companies, cosmetics manufacturers, food-testing facilities, universities, and industrial quality-control departments.
Its compact 108-liter chamber makes it attractive for laboratories that need precise environmental control without dedicating substantial floor space to a large reach-in chamber.
Pharmaceutical laboratories can use the HPP110 for stability studies involving smaller sample batches or individual product-development projects.
Industrial facilities can use it for material-conditioning procedures and environmental testing.
Research institutions may use the chamber for experiments involving controlled temperature and moisture exposure.
The HPP110 is also useful as a secondary environmental chamber when laboratories need to maintain different conditions simultaneously.
Peltier Heating & Cooling Technology
One of the distinguishing features of the Memmert HPP110 is its energy-efficient Peltier heating and cooling system.
Peltier technology uses thermoelectric elements to transfer heat when an electrical current passes through semiconductor junctions.
By controlling the direction and intensity of the electrical current, the system can provide both heating and cooling.
Unlike conventional refrigeration systems, Peltier technology does not require a compressor or conventional refrigerant circuit.
This reduces the number of mechanical components and can simplify maintenance.
The HPP110 incorporates Peltier elements in the rear of the chamber, with separate control of upper and lower element groups to help maintain uniform environmental conditions.
The system provides a temperature setting range from 0°C to 70°C when humidity regulation is not active.
When active humidity control is used, the temperature setting range is 5°C to 70°C.
The lowest attainable temperature depends on the surrounding laboratory environment. Memmert specifies that the minimum operating temperature requires an ambient temperature at least 20°C higher than the desired chamber temperature.
For example, reaching a 5°C chamber temperature requires suitable ambient conditions and operation within the manufacturer's specified working envelope.
The Peltier system is particularly attractive for laboratories performing extended stability studies because it provides controlled heating and cooling without the vibration and mechanical complexity associated with compressor-based refrigeration.
Active Humidity Control & Dehumidification
The Memmert HPP110 incorporates active humidity regulation from 10% to 90% relative humidity.
Unlike conventional incubators that rely on passive evaporation from a water pan, the HPP110 actively controls both humidification and dehumidification.
Humidification is provided by an integrated hot-steam generator.
Distilled water is supplied from an external reservoir through a self-priming pump.
When the chamber requires additional moisture, the controller activates the steam generator to increase relative humidity.
Dehumidification is accomplished using a cold trap integrated with the Peltier temperature-control system.
This allows the chamber to reduce moisture levels when relative humidity exceeds the selected setpoint.
The humidity controller provides digital resolution of 0.1% RH and setpoint accuracy of 0.5% RH.
The ability to regulate both temperature and humidity makes the HPP110 suitable for pharmaceutical stability testing, packaging studies, and material-conditioning procedures.
Actual attainable temperature and humidity combinations depend on the manufacturer's operating envelope, chamber loading, and ambient laboratory conditions.
For best performance, laboratories should use appropriate distilled water and maintain the external water reservoir according to the manufacturer's instructions.
TwinDISPLAY ControlCOCKPIT & Programming
The Memmert HPP110 incorporates the manufacturer's TwinDISPLAY ControlCOCKPIT, featuring two high-resolution TFT color displays.
The controller uses adaptive digital PID technology to regulate temperature and humidity.
The displays provide direct access to environmental setpoints, operating information, alarms, and programming functions.
The system supports programmable temperature and humidity profiles using Memmert's AtmoCONTROL software.
AtmoCONTROL allows laboratories to develop, manage, and transfer operating programs through compatible Ethernet or USB connections.
This is particularly useful for environmental cycling, product-conditioning procedures, and stability studies involving multiple operating stages.
The controller also incorporates a SetpointWAIT function.
SetpointWAIT prevents the programmed process time from beginning until the chamber reaches the selected temperature.
This helps ensure that timed experiments are based on actual environmental conditions rather than simply the moment a program is initiated.
The digital timer supports operating periods from one minute to 99 days.
The controller also stores program information in the event of a power interruption, supporting recovery of operating settings when power is restored.
Temperature Monitoring & Environmental Stability
The Memmert HPP110 incorporates two Class A Pt100 temperature sensors using four-wire measurement circuits.
The sensors continuously monitor chamber temperature and provide mutual supervision.
If one sensor experiences a malfunction, the system is designed to detect the problem and support continued monitoring through the remaining sensor.
This redundant temperature-sensing arrangement provides additional protection for valuable samples and extended experiments.
The Peltier heating and cooling system works with forced-air circulation to distribute conditioned air throughout the chamber.
The controller adjusts heating and cooling output to maintain the selected temperature.
For pharmaceutical stability studies, consistent temperature control is essential because environmental variations can affect product stability and experimental reproducibility.
The HPP110's programmable controller and integrated monitoring functions support controlled testing procedures.
Actual chamber uniformity and stability should be verified under the laboratory's intended operating conditions.
Pharmaceutical Stability Testing & ICH Applications
The Memmert HPP110 was developed with pharmaceutical stability testing among its primary applications.
Stability studies evaluate how environmental conditions affect the quality of pharmaceutical products over time.
Commonly used ICH stability-study conditions include 25°C/60% RH, 30°C/65% RH, and 40°C/75% RH, depending on the product and applicable testing protocol.
The HPP110's temperature and humidity operating capabilities accommodate these commonly used conditions.
Its active humidity regulation, programmable controls, and integrated monitoring functions make it particularly useful for extended studies.
The compact chamber is suitable for laboratories evaluating smaller product batches or conducting development-stage stability studies.
The SetpointWAIT function provides an additional advantage by allowing timed procedures to begin only after the selected environmental conditions have been reached.
However, the ability to maintain an ICH temperature and humidity setpoint does not independently establish regulatory compliance.
Laboratories conducting regulated stability studies should complete appropriate qualification, calibration, environmental mapping, monitoring, and documentation.
When properly qualified and maintained, the HPP110 can serve as an important component of a pharmaceutical stability-testing program.
Chamber Construction & Sample Accessibility
The Memmert HPP110 incorporates a stainless steel interior designed for durability and ease of cleaning.
The chamber provides approximately 108 liters of usable capacity.
The interior measures approximately 22 inches wide, 18.9 inches high, and 15.8 inches deep.
The exterior cabinet measures approximately 29.3 inches wide, 34 inches high, and 26.5 inches deep.
The insulated stainless steel outer door incorporates a two-point compression locking system.
An inner glass observation door allows researchers to inspect samples while minimizing environmental disturbances.
The manufacturer-standard configuration includes two stainless steel grid shelves.
The actual number of shelves included with the refurbished unit should be verified.
The chamber supports a maximum combined load of approximately 330 pounds, although individual shelf loading must remain within the manufacturer's limits.
The stainless steel construction is suitable for a broad range of laboratory samples, packaged products, and material-testing applications.
Safety Systems & Environmental Monitoring
The Memmert HPP110 incorporates multiple safety systems designed to protect samples and support reliable operation.
The controller includes an autodiagnostic system that monitors temperature and humidity regulation.
Audible and visual alarms alert operators to relevant environmental deviations.
The chamber incorporates selectable overtemperature and undertemperature protection systems.
Memmert's AutoSAFETY function automatically follows the selected temperature setpoint within a defined tolerance range.
If chamber temperature exceeds the established limits, the system activates the appropriate alarm and protective response.
The controller also supports calibration at multiple temperature points and two humidity calibration points.
These functions are useful for laboratories performing extended environmental studies or maintaining documented operating procedures.
For regulated applications, independent environmental monitoring may be necessary to establish complete temperature and humidity records.
