With the practical screw tool you can tightly close our vials of the All-in-One series - good for transport and storage of sample material.

The new AF-2000 LED light source series for fluorescence microscopy offers high variability and optical performance at a low price.

The preservation of valuable samples by cryo storage is becoming more and more standard in science and research as well as in medicine. In these areas, biological sample material is frozen at sometimes very low temperatures in order to maintain the vitality of whole cells or functional cell structures over a longer period of time. Sample vials made of the fluoropolymer PFA are particularly well suited for the storage and transport of sensitive samples. PFA is an ultra-pure, high-end polymer that is stable at temperatures as low as −200°C.

In this video, we will show you how to properly clean soiled optical filters and beam splitters and which items you will need for it.

For Multiplex PCR we offer high quality optical fluorescence filters which are specially matched to all common fluorescent dyes such as FAM, ROX, HEX, Cy5, JOE, etc. The filters or filter sets are highly selective and have a transmission of >95%.

Benefit from the manufacturer's warranty for hard-coated optical filters.

New imaging technologies (cameras, sensors) require very flexible shapes and diameters of optical filters. Requirements can vary from very large sizes (e.g. 280 x 280 mm) to very small sizes (e.g. 2 x 4 mm or 3 mm diameter). AHF can provide such special-sized filters to its customers.

Step into a new dimension of sample transport in ultra-trace analysis! The new xLess system developed by AHF analysentechnik fulfils challenging tasks for sample transport systems in ultra-trace analysis with ICP-MS: Long-distance transport from the autosampler to detector, automatic and continuous control in 24/7 operation mode, stable measuring over minutes in ultra-pure conditions which ensure highest sample integrity.

Beam distortion, ghost images, disturbing background signals or background radiation are problems that are perceived as very disturbing by users in optics and photonics, fluorescence microscopy, high-resolution microscopy or in the development of handheld systems.

Laboratory users don’t want to have contamination in samples they analysing. Especially in ultra-trace analysis when measurements of smallest element concentrations are to be detected, contaminations can distort significantly the analysis result. This can perhaps also lead to a loss of an unique sample. Learn more about how to reduce contamination risks and work more effectively with All-in-one sample vessels from AHF analysentechnik.

The new light source CELESTA from Lumencor delivers approximately 1 watt of output power from each of its 7 individually addressable solid-state laser light sources (7 watts total). The laser outputs are allied to sophisticated control and monitoring systems to deliver the performance needed for spinning disk confocal microscopy, optogenetics and other advanced imaging applications.

Allocate and recognize your sample vials better with permanent markings. With our laser labeling system we are able to apply your individual engraving permanently on nearly all surfaces.

Maybe you know that: You want to reproduce an experiment with a fluorescence microscope and despite detailed instructions, it does not want to work. Here, the Argolight calibration systems are the solution to rule out uncertainties on the instrumental side.

The APS-2000 is an effective system for use in ultra-trace element analysis (< 10 ppt), especially for sample preparation in ICP-MS.

We offer filter designs which suit perfect to your needs and your system. You benefit from 25 years of interdisciplinary expertise in developing and specifying optical filters.

AHF analysentechnik offers highly selected optical filters for TIRF applications which are mounted in special filter cubes. They are available for microscopes from Nikon, Olympus, Zeiss and Leica.

Are you still using traditional lamps for your microscope needs? Do you want something brighter and more stable that avoids the use of mercury and consumes less power? AHF analysentechnik offers LED light sources from Lumencor which are innovative, powerful, pure, stable, durable and cost-effective lighting solutions as well as perfectly matching optical filters.

We offer bottles made from high-purity virgin PFA (Perfluoroalkoxy polymer) with a standardized GL45 screw thread for connecting the bottle to multifunctional adaptors and other functional attachments.

Spray chambers are crucial for sample introduction in ICP instruments. When the nebulizer has generated an aerosol of the liquid sample, the chamber separates the larger droplets of the aerosol from the smaller ones. That introduces the sample smoother into the plasma.

The patented Burgener parallel path nebulizers offer a precise and reliable technique, which comply with the basic request for precise and reliable sample introduction in ICP-MS and ICP-OES, especially with samples containing high solids or particles.

AHF analysentechnik offers skimmers and samplers (cones) for most common ICP-MS instruments as well as a special protection for cleaning.

Flow cytometry is a well established biophysical technology for cell counting and cell sorting, esp. for blood cells in routine and research. To adjust the system set-up to the samples, different laser combinations will be necessary. For optimizing the S/N ratios, it will be always recommended to check the optical components: Specific bandpass filters and precisely selected dichroics (“longpass filters”) should be precisely matched to the combination of lasers and the specific dyes.

Optical filters are always a necessary requirement for optimized live cell imaging documentation. They must fit correctly into the puzzle set by the whole complex system – Comprising: Microscope set up, the fluorophores used, variations in the sample, detector specifications, excitation source type, and personal preferences.

Optical filters are crucial for imaging systems in research and industry. Particularly when image signals are captured in sensor and control systems they play a key role in filtering out of unwanted signals.
