Use of expensive chemicals has made the precise dosage of microvolumes an important and critical stage of laboratory work, especially in the field of biotechnology. Operation in the critical range within 0.2 µl to 1,000 µl sets rigid requirements to the make of dosers which provide for a high precision and reproducibility of dosage.
Finpipet Digital droppers are of streamlined shape and offer improved ergonomics for laboratories which carry out a large number of routine studies. The rounded handle, modified stop, and a large display improve the comfort of the lab assistant and efficiency of operation.
Finpipet Digital droppers offer the following advantages in dosage of liquid chemicals: soft removal of the tip due to the reinforcing transmission mechanism and «super-expulsion» of liquids for droppers that dose microvolumes between 0.2 to 40 µl.
All droppers of macro-range offer a unique, specially designed piston mechanism which fully eliminates contamination because of turbulence, which is a general problem in dosing macro-volumes.
To provide absolute sterility, all Finpipet Digital droppers may be subject to full autoclaving. Each dropper also has a small area for a safety tag on the stop, and a special bracket for convenient storage of droppers on the shelf.
