3 ml sample cups for AquaPi, AquaPi Plus and EZ-Pi Plus. Can also be used with Microtrough for surface tension measurements and calibration. One set contains 5 antistatic bags each containing 10 cups. Using consumable polypropene vials instead of glass reduces contamination risk significantly – glassware should be thoroughly cleaned with Piranha solution or similar to qualify for surface tension measurements. Specifications: Material: Polypropene and carbon Temperature range: 0-100 °C
SKU: 8510 Kibron Delta-8 is a unique surface tension platereader for high throughput applications. The Delta-8 is the only surface tension plate reader in the market. It can determine the CMC (critical micelle concentration) of a surfactant up to one hundred times faster than with conventional tensiometers. Surface tension is measured by our proprietary DyneProbe which is ultracompact and requires no correction factors, as usually found with rings and plates. DyneProbes works also with cationic surface active agents. The Delta-8 uses standard size detection plates and conventional dispensing systems. Each well can be charged with individual samples or in the case of CMC determinations with aliquots of solution of different concentration. Before every run, the DyneProbes are heated using the Kibron DyneClean furnace. The bottom end of each probe is brought into contact onto a (very) hot surface. Upon contact, the tip of the probe is heated to around 600 °C. This ensures consistent and repeatably clean surfaces. Alternatively, or as a complimentary method the probes can be dipped in a washing cassette containing the appropriate cleaning solutions. A typical CMC determination consists of: 1: Dispensing aliquots of solution: Liquid handling is done using multichannel handheld pipettes or by a pipetting robot. 2: Probe cleaning: The DyneProbes are heated to red hot to burn off all contaminants. 3: Immersion and withdrawal: The DyneProbes are positioned above a row of 8 wells and immersed gently. The force on the plate is measured continuously (400 times/s) and upon withdrawal the surface tension is determined. 4: Analysis: Up to 96 data points can be acquired in around 3 minutes. These are automatically logged to a PC and the CMC is calculated by our analytical CMCeeker software.

DeltaPi is a tensiometer especially developed for studying interactions in biological systems. DeltaPi and DeltaPi-4 Kibron’s unique single and 4-channel Langmuir-tensiometers Kibron DeltaPi and DeltaPi-4 are novel types of instruments: Langmuir-tensiometers, which allow you to measure the binding of drugs, peptides, and proteins to lipid membranes – easily and with unparalled sensitivity. We innovate instruments for your innovative science. Biomembranes and lipids are entering the forefront of biosciences, biotechnology and drug discovery. In these studies lipid monolayers have paved way to breakthroughs in the elucidation of the molecular mechanisms of action of lung surfactants, antimicrobial peptides, lipid signaling, blood coagulation, and cell adhesion, just to name a few examples. Drug-lipid and protein-lipid interactions have emerged as a new, very exciting area in drug discovery, deciphering the roles of e.g. phosphatidylinositols (PIPs) in controlling cytoskeleton-membrane interactions. Along similar lines, recent findings have demonstrated the key role of lipid membranes in promoting the formation of toxic oligomers by Alzheimer Abeta peptide, prions, alpha-synuclein, and IAPP (amylin). DeltaPi series of Langmuir-tensiometers allow you to detect the penetration of drugs, peptides/proteins and nucleic acids into monolayers of specified lipid composition and at precisely controlled lateral packing density. The volume of the magnetically stirred subphase is minimally 150 microliters, which keeps your material consumption very low. One milligram of an antimicrobial peptide, for instance, is sufficient for a comprehensive characterization of its lipid-binding properties. Further, the choice of materials eliminates unwanted non-specific surface effects. DeltaPi is a single-channel model, while DeltaPi-4 is equipped with four parallel microbalances, increasing significantly the throughput of experiments. When you are in a hurry and need to generate data fast, DeltaPi-4 is your choice. Both instruments measure surface tension with Kibron’s thin wire probes (DyneProbes) from small subphase volumes. They are compact and have an open and robust construction, easy to clean and maintain, operated with our intuitive software, DeltaGraph. Reproducibility and reliability go hand-in-hand in science and in all Kibron products. DeltaPi and Deltapi-4 outperform all competing products, no matter how you compare them. This is the reason why you find Kibron equipment in leading research laboratories worldwide.
