LED Technology HPTLC Documentation System Providoc DD80

This is the latest device in the Biostep range.

It captures the image of the plate thanks to its high-resolution digital camera (24 million pixels) equipped with a high-performance auto-zoom, autofocus lens.

Its high sensitivity enables detection of weak fluorescence.

With Providoc© DD80 documentation system, you have not only the opportunity of recording images under white light but also under UV light. Therefore, the fluorescent behavior of the substances can be documented and helps to identify the substances. It is advantageous
to record the images of a TLC/HPTLC-plate under white light, UV 254 nm, UV 310 nm, UV 385 nm and 366 nm without changing the position of the plate for observing the spectral properties of a given spot precisely. For this reason, it is important that the dark hood is equipped with light sources for white light, UV 254 nm, UV 310 nm, UV 385 nm and 366 nm which can be switched on/and off optionally. Another point is the necessity of a high resolution camera with high color fidelity. Images recorded in this way can be quantified by an appropriate software similar to the process with electrophoretic gel.

The illumination cabin is equipped with 2 EPI white-light lamps, 2 UV 254nm tubes, 2 UV 366nm LEDs, as well as 4 UV 310nm LEDs, 2 UV 385nm LEDs and a white-light lamp for transmission reading, all with appropriate filters.

Images are displayed directly on your computer using dedicated software Argus X2 software.

Illumination:

• Large illumination compartment 390 x 385 x 280mm (W x D x H)
• Provides overhead illumination of TLC/HPTLC plates with 2 x 254 nm 8 watts UV Lamps, 4x UV LED
• 310 nm, 2x UV LED 345 nm, 2x UV LED 366 nm, 4x white LED
• Allows to illuminate from below (transparency) the tlc plates thanks to 1x white LED, for transmission analysis

Observation:

• The transparent support of the base, covered with an acrylic sheet, makes it possible to observe TLC plates up to 200 x 200mm.
• UV circuit breaker when opening the cabinet (user protection). Switch to keep the lamps on for certain jobs ( Preparative Thin Layer Chromatography).

Capture head:

• Upper module consisting of a camera support plate, which acts as an interface and completely protects the system from stray light.
• Special high-quality optical glass filter for UV work, which can be mounted on the filter holder if required. Filter for stable color reproduction and high resolution.

Software Argus X2

Special dedicated software for saving, processing and archiving images taken by the ProViDoc DD80 camera, ArgusX2 makes it possible to qualitatively manage images and:

• Enlarge them
• Change format
• Change colors, shine, sharpness, etc… to reach the best adjustment in order to make it possible to visualize all the tasks, even the weakest ones
• Compare several adjustments
• Add comments, shapes, scales and Rf indices
• Add date-Classify them in files saved by passwords,
• Compare them, superimpose them, etc.-Edit reportsfor each of the programmed methods

Each image is automatically saved with the date, user name and unique identification number. It can therefore be stored according to GLP guidelines and can even be password protected if desired.
