Rugged, easy to handle device for mobile leak detection

This leak detector is characterized by:
Leak detection based on Quartz Window Sensor technology
Compact dimension and low weight (5 kg)

CV versions extend the pure water vapor capacity up to 1000 g/h (at 100 mbar and 30 °C ambient temperature).
A high gas ballast flow warms up the pump and dilutes condensable gases (> 2 N.m3/h or 33 slm at 1 bar abs.).

Dry Screw Pumps. Optimum Ultimate Pressure. Absolutely Oil-Free. Cool-Running.

With HeptaDry, Pfeiffer Vacuum is once again providing the industry with another reliable, high-quality product. The pumps from this new series of dry screw pumps are optimally suited for their applications in connection with low and medium vacuum.

Polarized light microscopy provides all the benefits of brightfield microscopy and yet offers a wealth of information, which is simply not available with any other optical microscopy technique such as refractive indices, birefringence, retardation, extinction angle, pleochroism.

The B-500 microscopes have been designed for the best performance in routine laboratory use. According to the models, two different optical systems are available (InfiniFix and IOS).

The B-350 series presents the right balance between price and quality.

Thanks to its wide range of models, it can be successfully used both in advanced teaching situations and in laboratories.
