Repeater pipettes are perfect for dispensing a similar quantities frequently into quite a few receptacles without having pausing in between Each and every dispensing approach, maximizing velocity and efficiency.
Plastic, disposable pipettes are practical in applications where by sterility can be a prerequisite. Serological Pipet Fillers support to aspirate and dispense liquids properly and with precision. The speed of both of those aspiration and dispensing is usually altered separately to operate with a number of liquids.
