Also called blood pipettes, volumetric glass or plastic transfer pipettes used for whole blood, serum, and other viscous fluids; most Ostwald-Folin pipettes are used for clinical laboratory testing.
What is the main difference between volumetric pipet and Ostwald-Folin Pipet?
aqueous solution. Ostwald-Folin pipettes have bulb closer to the delivery tip unlike volumetric pipett which has at center. These (OF) are used for accurate measurement of viscous fluids, such as blood or serum.Nov 11, 2012
What are the different classification of pipettes?
The five grades of pipettes include disposable/transfer, graduated/serological, single-channel, multichannel, and repeat pipette.
Oswald-Folin pipettes are a type of volumetric pipette with bulbs near the delivery tip (see Figure 2). They are TD pipettes, but are designed for use with more viscous fluids such as blood or serum.
What is Ostwald pipette?
Also called blood pipettes, volumetric glass or plastic transfer pipettes used for whole blood, serum, and other viscous fluids; most Ostwald-Folin pipettes are used for clinical laboratory testing.
How do you use a TC pipette?
Unpack the pipette from the upper end to keep the tip sterile as long as possible. Attach the pipette to a pipet helper and immerse the tip into the liquid. Aspirate and dispense liquid 2-3 times to pre-wet the inside of the pipette. Aspirate the desired liquid volume and hold the pipette at eye level.

What is TC pipette?
TC or TD abbreviated for “to contain” and “to deliver” respectively. In a 'TC' marked pipette, the contained quantity of the liquid corresponds to the capacity printed on the pipette, While in 'TD' marked pipette, the delivered quantity of liquid corresponds to the capacity printed on the pipette.Feb 13, 2019
