42 Peltier-Cooled Incubator IPP ideal for Protein Crystallography
The sensitive protein crystals often grow for weeks or even months in the Memmert IPP Peltier-cooled incubator, as slowly and with as little vibration as possible, at constant temperatures between +4 °C and +20 °C. Above all thanks to its low-vibration properties, the Memmert cooled incubator IPP lends itself perfectly to store crystallisation preparations due to its precise temperature control by means of Peltier technology without compressor. In addition to the low noise and minimal vibration, the exact controllability of the incubator plays a crucial role in crystallisation, since temperature fluctuations can impact the reproducibility of the crystals, particularly during the nucleation phase.
The devices are amongst others used for determining the biochemical oxygen requirement, in minimum durability tests, in the incubation of cell and tissue cultures, in breeding insects or in clinical trials for vaccines.
Memmert cooled incubators IPP are available in five sizes from 32 to 749 litres chamber volume and a temperature range from 0 °C to +70 °C.

Breeding Model Organisms like Zebra Fish in the Constant Climate Chamber HPP
With the help of zebra fish, many universities and pharmaceutical companies do research on the cause, diagnosis and therapy of human diseases. To develop perfectly, zebra fish need as much peace and quiet as possible during growth. The constant climate chambers HPP 110 and HPP 260 with light module, which run without a loud and vibrating compressor provide the ideal environment. Peltier technology precisely heats and cools the interior without any disturbing vibrations and noises. Thanks to the fish breeding chamber’s LED lighting between 8 am and 10 pm, zebra fish can grow in a nature-like environment at a constant temperature of +28 °C.
The Peltier technology applied in the Memmert constant climate chamber HPP not only makes it possible to precisely control the temperature during long-term processes but also – even after many years of use – runs without any maintenance like changing the coolant, as it is required for compressor appliances.
Memmert constant climate chambers HPP are available in three sizes from 108 to 749 litres chamber volume and a temperature range from 0 °C to +70 °C.

Drying of Blood Pumps made of Polyurethane in the Vacuum Oven VO
If a heart insufficiency should occur in a patient, there is usually no donor heart available, so artificial hearts step into the breach as lifesavers. In the production of artificial hearts the highest standards of quality apply for all processes. In a renowned German company clockmakers and precision engineers are responsible for the precise finishing, down to the micrometer, of pumps and cannula, which takes place under cleanroom conditions, since the slightest unevenness or deviation could lead to life-threatening complications for the patient.
Memmert vacuum ovens are used for the drying process. For example, the assembled blood pumps are subsequently dried and degassed in the vacuum oven VO. The gentle drying of the components made from heat-sensitive polyurethane is done in a vacuum at 30 °C over a period of 24 hours. In doing this, the manufacturer makes use of the advantages of the vacuum cycles in the Memmert vacuum oven. The pressure in the interior is briefly reduced by the programme under controlled circumstances, so that humidity and possible residue is removed more quickly.
Memmert vacuum ovens are available in three sizes from 29 to 101 litres and a temperature range from +20 ºC to +200 ºC. MORE INFO. 81
