Benchtop Colorimeter

Labtron Benchtop Colorimeter measures color and concentration with light filters ranging from 420 to 660 nm and uses a high-quality silicon photodiode for reliable detection. It includes dual knobs for precise focusing on samples with varying opacity, ensuring stability and reproducibility of ±5 nm.

Chauvet Caves

This extraordinary cave, located in the southern region of France, unveiled its secrets back in 1994.

32,000 Years Ago: The Oldest Documented Paintings

The paintings found here, the oldest ever documented, date back to 32,000 years ago.

Sealed Cave: 20,000 Years of Preserved Integrity

The Chauvet Cave, named in honor of one of its discoverers, had maintained its integrity until that moment, protected by a landslide that had sealed the entrance 20,000 years earlier.

Animal Kingdom Represented: From Mammoths to Owls

These cave paintings are predominantly dedicated to depictions of animals, ranging from majestic mammoths, bears, cave lions, rhinoceroses, bison, and aurochs, to more harmless creatures like deer, reindeer, horses, and even an owl.

Hunting in Action: Lionesses and Prey in Motion

The most impressive wall depicts dozens of lionesses chasing a group of mammoths, bison, and rhinoceroses. The artists have masterfully captured the dynamism of the scene, outlining with variations in thickness and intensity the silhouettes of the animals in the foreground and background. Accurate shading on the backs and muzzles contributes to a sense of three-dimensional volume.

Artistic Mastery: Color, Chiaroscuro, and Engraving

The extraordinary quality of the painted images is evident in the mastery of color and chiaroscuro, skillfully combining painting with engraving.

Anatomical Details: In-Depth Knowledge of Subjects

Surprisingly, the unknown prehistoric artists demonstrate a detailed knowledge of the anatomy of the subjects, creating works that suggest three-dimensionality and movement.

Unveiling the Mystery: Scientific Analysis and Precise Dating

This artistic mastery puzzled scholars for a long time, as it seemed incredible that prehistoric humans could produce such refined works. Only through in-depth scientific analysis was it possible to precisely date these extraordinary cave paintings, revealing the true extent of the artistic skills of our ancestors.

Detection Limit

The detection limit refers to the lowest concentration or amount of a substance that can be reliably detected by an analytical method or instrument, but not necessarily quantified. It is a critical parameter in various scientific and industrial fields, especially in analytical chemistry, environmental monitoring, and clinical diagnostics. The detection limit indicates the sensitivity of a method, essentially marking the threshold at which the instrument or technique can distinguish the substance from background noise. The detection limit can depend on several factors, such as the sensitivity of the instrument, the sample matrix, and the type of analysis being conducted. A lower detection limit means higher sensitivity, allowing for the detection of very small quantities of the substance, while a higher detection limit indicates that only larger concentrations can be reliably detected.
