PRODUCT DESCRIPTION
Automatic pipettes are piston-type pipettes designed for accurate collection and transfer of liquid samples. Shown here are air-displacement pipettes in which the plunger and interchangeable tip are connected to each other by an air channel, through which the pressure from the plunger is transferred to the liquid, which ensures that the liquid is aspirated and then extruded.
Automatic pipette dispensers (pipettes) are:
• single-channel dispensers or multi-channel dispensers for 6, 8, 12 or 16 channels;
• multichannel pipette dispensers with variable distance between tips (to change the format of work – from test tubes to plates and vice versa);
• pipettes with constant (fixed) or variable volumes of pipetting (various volumes covering the range from 0.1 to 20,000 µl)
• mechanical pipette dispensers or electronic.
Mechanical pipettes have a manual drive, unlike electronic pipettes, which have an electric motor to control selection and dosing. The electronic pipette allows for more uniform sampling and dispensing of the sample and improves reproducibility by virtually eliminating human error. Electronic pipettes allow not only direct dosing and reverse dosing, like automatic mechanical pipettes, but also dosing with mixing, dosing with cycle counting, multiple dosing, dilution, dilution with mixing, sequential dosing, multiple set.
Tips for automatic pipettes are an essential consumable. There are both universal tips that are suitable for almost any pipettes, and specialized ones that are compatible with pipettes of a certain manufacturer. Made from high quality plastic. There are several types of packaging: packages, towers, or tripods.
Tip options:
• sterile or non-sterile;
• without filter – for working with non-volatile, non-radioactive and non-infectious substances;
• with a filter that prevents contamination during PCR, DNA sequencing and other methods that use volatile, radioactive, biologically hazardous and caustic materials;
• elongated – for working with narrow long test tubes, prevent contamination of the pipette;
• apyrogenic – free from DNA, RNA, pyrogens, suitable for use in PCR;
• with a chamfer – the presence of a chamfer reduces the capillary effect that occurs when the tip of the tip comes into contact with the wall of the test tube;
• with a wide opening for work with viscous samples and cells.
Features of pipettes from different manufacturers:
• easy pressing of the dosing button;
• blocking of the operating button, which excludes accidental volume changes;
• large, clear display;
• the handle and dosing button are made of a bactericidal polymer with silver ions, the destruction of 99.9% of bacteria on the surface of the dispenser;
• super-ejection mechanism;
• autoclavable cone and body;
• three-position ejector can be configured to work with both right and left hand;
• the presence of a radio frequency tag (RFID), which stores in its memory information about the date of calibration, maintenance;
• the ability to set the finger rest in the range of 120 °, which allows for comfort for both right-handed and left-handed people;
• patented seat and tip design for easy donning and secure fit, etc.
• Positive displacement pipettes are used for dosing viscous and volatile liquids as well as aggressive and radioactive liquids. In such pipettes, the piston is located inside the tip and is in direct contact with the liquid, which eliminates the formation of an aerosol in the tip, and subsequently prevents contamination.
Other devices are also used for dosing liquids: steppers – for sucking a large volume of a liquid sample with its subsequent multiple dosing in a selected volume, ranging from 10 to 5000 µl; diluters – dispensers with simultaneous dilution of dosed liquids, allow you to perform high-precision multiple, serial dilution for such analysis methods as atomic absorption, ICP spectroscopy, HPLC, gas chromatography, etc.; pipette pipettes – designed for dispensing large volumes (25-100 µl), provide suction for glass or plastic serological pipettes.
