The company VDS optilab Chromatographietechnik GmbH situated in Berlin was founded in 1987 by Mr. Roland von der Sitt and has been dealing with the production, development and sales of chromatography columns, separation phases and accessories ever since. VDS optilab was established on its founder’s experience at that time already who previously worked as production manager for a renowned HPLC columns manufacturer for many years.

The high quality of our products has impressed customers from all areas of research & development and quality control, starting from universities and regulatory authorities through small to medium level companies right up to large groups in the chemical and pharmaceutical industry. Nowadays, HPLC columns made by VDS optilab are utilized worldwide.
In 1990, the product range was expanded by the sales and production of equipment to supplement the existing HPLC systems. In the 1990s VDS optilab was very successful in this field and one of Germany’s most important providers of column thermostats, degassers and solvent recyclers.

Thanks to the merger with Muder & Wochele GmbH in 2002, our customers as well as we ourselves have profited from the bundled knowledge and expertise of both companies.

Since this merger we are focused mainly on our core business – HPLC columns!

As a result, we were able to develop our own separation phases based on spherical silica gel and present them in 2007 under the VDSpher brand name. Since then we have developed our VDSpher product family further continuously and can offer a wide spectrum of pore sizes, particle diameters and modifications, which are used successfully in the normal phase and reversed phase chromatography as well as the HILIC and the ion-exchange chromatography. We offer VDSpher columns for nearly all areas of application in UHPLC through analytical HPLC to semi-preparative and preparative chromatography.

A fantastic team of highly qualified and motivated employees with long-standing experience fully supports our company’s philosophy “high quality standards at reasonable prices”.

VDSpher® – Use a better column

The VDSpher phases product family was developed for users who prefer an uncomplicated and fast HPLC analysis. Our brand includes the following phases:

  • VDSpher® Classic & VDSpher® PUR
  • U-VDSpher® PUR
  • VDSpher® OptiAqua
  • VDSpher® OptiBio
  • VDSpher® MS
  • VDSpher® for preparative applications
  • VDSpher® Flash

The available particle diameters range from 1.8 µm to 55 µm. Bigger-sized particles such as 120 µm diameter can also be delivered upon request. The same selectivity from analytical to preparative chromatography (from UHPLC to preparative HPLC) enables a fast switch-over to a different particle size. For the user, the VDSpher phases permit a target-oriented “upscaling” from analytical HPLC through semi-preparative / preparative HPLC to separation in production scale. Even a “downscaling” of analytical HPLC to UHPLC is simply possible without performing numerous time-consuming tests.

For analytical HPLC the VDSpher phase of choice has a pore size of 100 Å and is suitable for analytes from small to medium molecular weight. In order to analyze larger molecules, VDS optilab offers wide pore silica gels with pore sizes in the range of 150 Å to 1000 Å. For preparative applications through to production scale, 75 Å separation phases are also part of our programme.

Benefit from the advantages of the VDSpher phases product family:

  • very good batch-to-batch stability
  • wide selectivity spectrum
  • very good selectivity
  • very high purity of the silica gels
  • narrow pore size distribution
  • narrow particle size distribution
  • high plate numbers
