Gentle vacuum drying for non-flammable and flammable solvents

Vacuum drying chambers are used in many areas of science and industry in order to dry heat-sensitive materials quickly and effectively.

Conventional drying processes can damage heat-sensitive materials such as food, medication, chemicals or electronic components, or change their product properties. Carrying out the drying process in a vacuum drying chamber reduces this risk to a minimum. Vacuum drying is one of the most effective and gentle drying methods available. The aim of this method is to gently dry a high-grade product that contains water or a solvent without endangering the materials. Drying in a vacuum drying chamber is particularly recommended for compounds containing flammable solvents. Due to the oxygen in the air in particular, these compounds often develop an explosive atmosphere during the drying process. This is prevented when dried in a vacuum drying chamber. Vacuum drying also minimizes the risk of scaling or oxidation residue.

In the vacuum-drying process, the material to be dried is subjected to a reduced pressure environment, which reduces the boiling point and aids evaporation of the water or capillary transport. The targeted supply of heat and pressure control optimizes the drying process. Another positive effect is the low energy costs, as the vacuum makes it possible to dry materials at very low temperatures.

Huge range of applications

Typical applications for vacuum drying chambers include drying heat-sensitive products, semiconductors, and electronic components such as connectors, switches, and relays after cleaning. The chambers are also used to condition materials such as plastics and resins, as well as for certain aerospace tests, for fast and gentle drying of powder or granulate, or for drying materials with low heat conductivity. Further applications include drying tissue samples in the fields of cancer research and pathology, drying easily decomposable materials such as pigments, proteins, or vitamins, or drying seed materials such as cornmeal in order to eliminate moisture.

BINDER constant climate chambers, now with an extended climate range

The climate range of the Binder KMF series of constant climate chambers is being extended to 98% relative humidity. This allows for an even wider range of applications.

In all areas of industry, ever higher requirements are being placed on the durability of materials and products. Material load testing carried out over a long period is used to test the temperature and humidity resistance of materials more intensively and to determine their durability under different climatic conditions. For this reason, BINDER GmbH has extended the climate range of the KMF series of constant climate chambers from 90% to 98% relative humidity. The extended humidity range makes it possible for test materials to be subjected to even tougher conditions. This is extremely advantageous in the electrical and electronics industry since, in this field in particular, test scenarios are often carried out at high humidity levels.

The constant climate chambers are designed for stress testing in long-term operation with stable temperature and humidity values. Test materials can be exposed to a temperature range of between -10°C and +100°C and humidity of between 10% and 98%. Due to the shallow depth and tall design of the device, it has a large access area so all operating elements are easily accessible from the front. In addition, an inner glass door with a seal protects the testing chamber from unwanted temperature fluctuations. This means that the test materials can be examined without having to open the door.

The testing chamber is fitted with a drift-free, capacitive moisture sensor, which helps with the quick reaction time of the steam humidifying system and allows for a short recovery time after the door is opened.

In addition, the device has a high resistance to chemicals since the evaporator is made of pure stainless steel. This means that no non-ferrous metals are used in the outer vessel, which prevents unwanted electro-chemical reactions. Air circulation on both sides guarantees homogeneous climate conditions across all test materials, even if the device is fully loaded.

Furthermore, the device is extremely flexible with regard to the water supply. If the water quality is acceptable, the device can be connected directly to the household water system. However, if the water quality is unacceptable, there is also the option of using the BINDER PURE AQUA Service water treatment system. This system processes faucet water and demineralizes it. There is also the option of attaching an external water supply set so that the device is not dependent on the water supply and installation location.

The constant climate chamber can also be modified by BINDER to suit any special customer requirements. Whether these are additional windows or doors, extra access ports for measuring instruments, a connection for a compressed air dryer or alternatively a CO2 supply, the BINDER INDIVIDUAL range is practically limitless.

New! Alternating climate chambers with unregulated compressed-air dryer for a dry and cold climate at the same time!

- With the unregulated compressed-air dryer, the climate range of the standard unit can be expanded to simulate a dry and cold climate at the same time.

- Simulation of complex temperature and humidity pairs can be handled with MKF and MKFT series.

- With MK and MKT series, specified temperature values are quickly achieved while specifically creating a dry climate at the same time.

- Dew points of down to -28 °C can be achieved.

- Availability: Immediate

- This option is upgradeable with all units of the MKMKFMKT and MKFT series.

Binder | Skin transplants save lives

Human skin cell cultures are incubated at DIZG in BINDER incubators for clinical use.

The first clinical use of cultured autologous skin produced at DIZG (German Institute for Cell and Tissue Replacement) was in 1995. The culture made a significant contribution to the life-saving treatment of a severely burned patient. Today, the Biotechnology Division of the institute is still primarily engaged in making cultured autologous skin available to such patients in burn centers quickly and reliably.

CB150 incubator creates standardised conditions to incubate human skin cell cultures, the institute uses several BINDER incubators of the CB150 series. Institute employees appreciate the optimal use of space of the chambers among other things. For cultivation, one to three postage-stamp sized samples of healthy skin are taken from the patient. From the samples, the body's own epidermal cells, so-called keratinocytes, are isolated for subsequent reproduction in a special culture system under standardized conditions....
