The most important parameters in liquid handling are dispense velocity and precision, which are translated into hardware by our experienced engineers. With our in-house software department reliability as well as reproducibility of results are ensured.
The rheological properties of a liquid determine dispense velocity and precision and thus the required hardware for processing samples of the specific application. Other properties that can be handled are polarity (through magnetic interaction or electrical charge), hydrophobicity, high or low surface tension, solubility, temperature, vapor pressure, air pressure.
With conductivity measurements Zinsser Analytic detects the liquid levels of different liquids which enables fully automated liquid-liquid-extractions of liquids that are insoluble in each other. Liquid level detection is also possible with special carbonized disposable pipetting tips.
Pipetting tips are either chosen from a variety of non-disposable tips with specific properties for each application – e.g. stainless steel, piercing, PTFE coated, filtration, heatable, ceramic coated, multiple channel tips etc. – disposable tips of various volumes (10 µL up to 10 mL, accuracy ± 1%) or from special glass or disposable viscous media tips (100 µL up to 50 mL, accuracy ± 0.5-3%).
Every non-disposable tip is also available as small volume tip, with a reduced diameter for a precise pipetting of smaller volumes.
Low surface tension is a tricky property to handle, since those liquids tend to drip from the pipetting tips. Zinsser Analytic developed several techniques to avoid this dripping and to safely transfer the full required volumes from A to B. For the opposite case of a high surface tension Zinsser Analytic provides solutions as well.
Also the pH value, temperature, polarity and changed pressure can cause undesired effects like precipitation or forming of emulsions, which can be retransferred into solution by several techniques, e.g. ultrasonication, vortexing, heating, etc.
