The specs that suggest: its most quantity is printed on the neck in the pipette; the dimensions in their divisions, represented as one/ten, 1/100; the calibration temperature; plus a legend determined as TD or TC, by the acronym in English of To Shipping and delivery (ex) or To Consist of (in), which implies to pour or empty, respectively. In addition, the specs show the temperature at which the pipette was calibrated.
Serological pipettes are Utilized in cell and tissue lifestyle purposes, and usually laboratory liquid dosage when in excess of 1mL volumes are pipetted. Serological pipettes are made of glass or polystyrene.
