Exact and Secure Pipetting of Plasma and Whole Blood

16 Nov 2017

This application note demonstrates the advantages of using positive displacement pipettes, like Gilson’s MICROMAN® E, over air displacement pipettes in diagnostic applications requiring exact and secure transfer of blood and plasma.

MICROMAN® E

Gilson, Inc.

The ergonomically designed MICROMAN® E positive displacement pipettes, along with disposable capillary piston (CP) tips, provide the highest precision when pipetting viscous, non-aqueous liquids such as oils, blood, glycerol, and more, while protecting the pipette from contamination. MICROMAN E is available in six models covering a volume range of 1 to 1000 µL. Reliable Dispensing Even with Viscous and Volatile Liquids MICROMAN E relies on positive-displacement technology to improve the precision of transferring viscous and volatile liquids. The capillary piston (CP) tips eliminate the air cushion between the sample and piston so volume accuracy is not affected by the sample’s properties. Tackle these issues with MICROMAN E: Viscous solutions—difficult to aspirate and stick to pipette tips. Volatile solutions—leakages are created from differences between solvent vapor pressure and the air pressure within the pipette. Cold liquids—delivered in excess amounts. Hot liquids—under-delivered amounts. Designed with Comfort and Performance in Mind The Red Dot Award winning design of the MICROMAN E features an improved handle shape that rests comfortably in your hand, with a large push-button for easy aspiration and dispensing. The volume-locking switch allows for easy volume adjustment and minimizes the risk of accidentally changing the volume during pipetting tasks. Overall Protection The positive-displacement technology of the MICROMAN E is ideal when dealing with infectious solutions and radiolabeled components. Since the disposable piston makes direct contact with the sample, the user and the pipette are protected. Within molecular biology and forensic sciences, any trace of a previous sample can lead to erroneous results and the disposable CP tips provide absolute protection against cross-contamination.

Sample preparation and processing includes fixation, staining, sectioning and slide mounting, using equipment such microtomes and cryostats. In choosing immunohistochemistry and immunocytochemistry kits, consider chromogens, staining method, antibodies, microscopes and imaging.Point-of-CarePoint-of-Care Testing (POCT) or Near Patient Testing (NPT) products are available for urine, blood and other clinical chemistry analyses. POCT includes: blood glucose testing, blood gas and electrolytes analysis, rapid coagulation testing (PT / INR), rapid cardiac markers diagnostics, drugs of abuse screening, urine strips testing, pregnancy testing, fecal occult blood analysis, food pathogens screening, hemoglobin diagnostics, infectious disease testing and cholesterol screening.Human PlasmaHuman plasma is the liquid component of blood, which carries blood components - nutrients, hormones, proteins, and waste - throughout the body. Plasma-based studies provide insights into biomarkers, immune responses, and disease mechanisms. Compare plasma handling tools and systems in our peer-reviewed product directory.Blood AnalysisThe analysis of blood is vital for many areas of life sciences and forensic investigations. Blood samples can be tested for a number of different reasons such as diagnosis, glucose levels, cholesterol and drug testing.Liquid HandlingLiquid handling involves the precise transfer, mixing, and dispensing of liquids in laboratory settings. It is essential for accurate and consistent results in biological, chemical, and pharmaceutical research. Automated liquid handling systems improve efficiency and reduce human error in sample preparation and analysis.
