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 produce comparable results that allow stable conclusions to be drawn. The sample to be examined can be of different nature, but they all have one thing in common: The temperature of the sample influences 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 space restrictions, precision requirements and low refrigerant, low vibration and low noise operation.

Precise measurement results thanks to precise technology

Dr. Neumann Peltier-Technik GmbH is dedicated solely to the development and manufacture of thermoelectric products. Thus we can only offer you efficient products in the field of control cabinet and surface temperature control, but would also like to make our profound wealth of experience in the field of laboratory technology available to you.

The Peltier technology is characterized in particular by a high-precision controllability of the temperature and is therefore often indispensable in the field of laboratory technology. But also other properties such as the largely low-noise and low-vibration temperature control of the samples as well as a fast change from cooling to heating operation offer decisive advantages over other cooling solutions. Possible areas of application for Peltier technology in the laboratory environment are therefore wide and include, among other things:
Temperature-controlled water baths: The investigation of liquids of any kind often requires precise temperature control. For this purpose, the use of our surface coolers at the water bath or a solution developed for you is suitable.

  • Thermocycler: Cyclical temperature control of the sample can be easily achieved using Peltier technology, since a reversal from cooling to heating operation can be easily achieved by reversing the current flow.
  • Centrifuges: In order to avoid falsification of the test results even during the use of a centrifuge, these can be precisely tempered using Peltier technology.
  • Refractometer: Results concerning the refractive index of a sample require an accurate and concentrated tempering of the sample.
  • Incubators: For temperature controlled storage of samples with lowest noise and vibrations
  • Tempering plates: These allow precise temperature control of e.g. laboratory glassware.

The use of Peltier technology is often indispensable in the applications mentioned above. We are happy to support you in the development of your product as an OEM-manufacturing company and thus ensure that you do not have to worry about the precise temperature control of your laboratory equipment.

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

Our laboratory technology in detail

Ice point thermostat

Our digitally controlled ice point thermostat provides a constant temperature source with 0 °C and an accuracy of +/- 0.01 °C. It is air-cooled and does not use any liquids. This eliminates leakage. It has a swivelling handle for safe transport and convenient positioning. In addition, the device can also be operated in a vertical position to ensure simple and safe filling when using thermal oil.

The ice point thermostat has a central hole with a diameter of 10 mm and 8 additional holes with a diameter of 7.2 mm. All holes are 150 mm deep and double insulated. The device reaches the ice point approx. 10 minutes after switching on and is HF interference-free, as no triacs or thyristors are used.

Tempering 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 -50°C to +60°C can be reached. The unit is equipped as a tabletop unit with feet and a robust electrical connection. Thanks to the water recooling, a compact design without exhaust fan and noiseless operation is achieved. Two built-in Pt 100 temperature sensors in the base plate and in the water heat exchanger allow external regulation and monitoring. For optimum operation, the optional SVS-03 power supply and controller can be easily connected via a special cable. In this way, the desired temperatures can be set precisely and kept constant. In addition, the control system automatically ensures that the temperature control plate is protected against overheating.

Temperature control 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. The temperature control plate ZTNG-310-A can be used for a wide range of applications. It has an integrated controller which can be used to set the desired target temperature by means of arrow keys. The temperature control plate is recooled with normal ambient air and therefore requires no liquid refrigerant or coolant. Due to the integrated wide-range power supply, the unit can be used worldwide without any restrictions.

Power supply and control

The SVS-03 was developed especially for the supply and control of the new tempering plate. It is designed to support and control all functions of the ZTNG-100-B optimally. The SVS-03 can be used anywhere without restrictions thanks to the wide range power supply.

The use of this power supply / control is the most convenient way to operate the ZTNG-100. Thanks to the precise control, you only have to select the desired temperature of the temperature control plate using the arrow keys. The SVS-03 then takes care of everything else for you, including monitoring the cooling water temperature and switching off the temperature control plate if necessary. The connection between the temperature control plate and the supply unit is established quickly and easily with the aid of a safe and firmly lockable plug connection and a special cable.
