Corrective action: Placement elbows as near the body as you possibly can, with arms and wrists prolonged in straight, neutral positions (handshake posture). Preserve work things within uncomplicated get to to limit extension and elevation of arm. Arm/hand elevation mustn't exceed 12” with the worksurface.
Plastic pipettes featuring thermoplastic polypropylene (PP) also are generally used. These have the advantages of becoming immune to An array of diluted base and acidic chemical substances. PP can also be a relatively difficult and durable number of plastic.
At Gilson, we provide usage of the devices and consumables that you should develop dependable final results. Our liquid handling remedies assure that you can attain your desired amount of throughput without compromising on your own experiments' precision, precision, or repeatability.
As an instance that occasionally things just Really don't work out as we desire, think about the piece of strong substance lodged within the nozzle on the pipette on the left.
