KSV is, as they themselves say "....the smart choice for interface design and analysis".
KSV brand for Langmuir-Blodgett (LB) troughs include technologies
from NIMA Technologies that Biolin acquired.
LB troughs are tools are used to produce monolayer's and multilayer systems for experiments.
|The observation for
thin surfaces of molecules on a liquid is credited to
Benjamin Franklin but it was the insight of physicist John
Strutt (better known as Lord Raleigh) who calculated the
film thickness of Oleic Acid on water as 1.6nm after Agnes
Pockels drew his attention to the idea. Incidentally this
also proved the value of Avogadro's number!
In the 1910~1920's Irving Langmuir built a trough to produce monolayers and subsequently, with his student Katherine Blodgett
famously produced monolayer films on a routine basis.
Langmuir was awarded the 1932 Nobel prize in Chemistry for
his body of work on surface chemistry. Langmuir's original
idea was that the chain length of the surfactants did not
affect the coverage as the molecules were vertically
Langmuir with Blodgett found that inserting a solid into a
water solution containing organic molecules will cause a
monolayer to form on the surface, hence opening the way to
producing the films (diagram right). Blodgett went on to apply this to glass and produced multireflective Fluorine layers in optics.
Katherine Blodgett was an interesting person in her own
right, the first to gain a Ph. D. in physics from Cambridge;
she broke many "glass ceilings".
The use of the
LB troughs today is widespread with modern hydrophobic
materials and applications in protein crystallisation and Brewster angle microscopy.
KSV LB troughs
KSV offer four series of troughs in different sizes and within each there are versions, accessories and options.
There will definitely be a system to suite your needs and budget.
