Laboratory technology – Because the details make a difference

Especially in laboratory technology, it is of utmost importance to exclude any falsification of the results. This is the only way to create comparable results that allow reliable conclusions to be drawn. The samples to be examined can be of various types, but they almost all have one thing in common: the temperatures of the samples influence the measurement result.

Not only are measurement results in the laboratory environment quickly falsified by incorrect temperature control, but the use of other temperature control methods in the laboratory is often not possible due to installation space restrictions, precision requirements and low-refrigerant / low-vibration & low-noise operation.

Accurate measurement results through precise technology

The Dr. Neumann Peltier-Technik GmbH has dedicated itself solely to the development and manufacture of thermoelectric products. Thus, we can not only offer you efficient products in the field of control cabinet and surface temperature control, but would also like to provide you with our wealth of in-depth experience in the field of laboratory technology.

The Peltier technology is characterized in particular by a highly accurate controllability of the temperature and is accordingly often indispensable in the field of laboratory technology. But also other properties such as the largely low-noise and low-vibration temperature controlof the samples as well as a fast change from cooling to heating mode offer decisive advantages over other cooling solutions. Possible application areas of Peltier technology in the laboratory environment are therefore wide-ranging and include:

  • Tempered water baths: The examination of liquids of any kind often requires precise temperature control. For this purpose, u.A.the use of our surface coolers at the water bath or a solution developed for you
  • Thermocycler: A cyclic temperature control of the sample can be easily realized by means of Peltier technology, since a reversal from cooling to heating mode can be easily implemented by reversing the current flow.
  • Centrifuges: To exclude falsification of the test results even during the use of a centrifuge, they can be precisely tempered
  • Refractometer: Results,which concern the refractive index of a sample, require an accurate and concentrated tempering of the sample.
  • Incubators: For temperature-controlled sample storage with lowest noise and vibration.
  • Tempering plates: These allow precise tempering of e. g. E.g. laboratory glassware

In the above-mentioned areas of application, the use of Peltier technology is often essential. We are happy to support you here in the development of your product as an OEM manufacturing company and thus ensure that they do not have to worry further about the precise temperature control of your laboratory devices.

In addition to manufacturing OEM products, we can offer you already fully developed products in the field of laboratory technology. Thus, we can offer you our high-precision ice point thermostat as well as temperature control platesin different sizes. Of course, our laboratory products also meet our highest standards of quality and precision.

Our laboratory technology in detail

Ice point thermostat

Ourdigitally controlledice point thermostat forms a temperatureconstant sourcewith 0 °C and an accuracy of +/- 0.01 °C. Esis air-cooled and does not use any liquids. Thus, leakages are excluded. Es has a swiveling handle, which allows safe transport as well as convenient placement of the device. In addition, the device can also be operated in a vertical position to ensure easy and safe filling when using thermal oil. .

Das ice point thermostat offers a central hole with a diameter of 10 mm, as well as 8 other holes with a diameter of 7.2 mm. All holes are 150 mm deep and double insulated. The device reaches the ice point about 10 minutes after switching on and is RF-interference-free, since no triacs or thyristors are used.

Temperature plate ZTNG-100-B

The temperature control plate ZTNG-100-B is the successor of the previous cold plate ZTNG-100-A and can now both cool and heat. Temperatures in the range of up to -50°C to a maximum of +60°C are achieved. The unit is designed as a tabletop unit with feet and a robust electrical connection. Thanks to the water recooling, a compact design without exhaust fan, as well as a noise-free operation is achieved. Through two built-in Pt 100 temperature sensors in the support plate and in the water heat exchanger, external control and monitoring is possible. For optimal operation, the optionally available power supply and control SVS-03 can be connected in a simple way, using a special cable. This allows the desired temperatures to be set precisely and kept constant. In addition, the regulation automatically ensures that the temperature control plateis protected from overheating.

Temperature plate ZTNG-310-A

The temperature control plate ZTNG-310-A covers a temperature range from -10°C up to +60°C with an accuracy of +/- 1 K. It has an integrated controller above which the desired target temperature can be set by means of arrow keys. The temperature control plateisrecooledwith normal ambient airandneedstherefore no liquid coolingor coolantat all. .

Thanks to the integrated wide-range power supply, the devicecan be used worldwide without restrictions.

Power supply and control

The SVS-03 has been designed quite specifically to power and control the new temperature control plate. It is designed to optimally support and control all functions of the ZTNG-100-B. The use of the SVS-03 is, thanks to the used wide range power supply, possible everywhere without restrictions. .

Using this power supply / control is the most convenient way to operate the ZTNG-100. Thanks to the precise control, you only need to select the desired temperature of temperature plateby arrow keys. Everything else, as well as the monitoring of the cooling water temperature and the possibly required shutdown of the temperature control plate, then takes over the SVS-03 for you. The connection between the temperature control plateand the supply unit is made easily and quickly with the help of a secure and tightly lockable plug-in connection and a special cable.
