Pipette tip geometry can influence both accuracy and precision, allowing a droplet so small it can hardly be seen to have major implications in many laboratories
Optimal performance of a pipetting system relies on its pipette tips.
Factors dependent on tip geometry can influence both accuracy and precision.
A droplet of reagent or sample so small it can hardly be seen can have major implications in clinical, research and quality control laboratories.
In full recognition of this, John Morris Scientific supplies laboratories all over Australia with Gilson's highest quality Diamond tips, designed to complement pipetting systems for advanced life science techniques.
For over 25 years, Gilson pipettes and tips and have been the recognised standard for accuracy, precision and reliability.
Whether users are working at 0.1µl or 10ml, Gilson has the pipettes and tips to suit their needs.
The fact that ordinary tips may not fit properly is seen as a major cause of poor performance.
In recognition of this, Gilson has designed its Diamond tips with built-in sealing rings, specially designed to form a perfectly airtight seal on its Pipetman.
The diameters of the tip-collar and the tip-holder are also calculated to fit perfectly.
In addition, Gilson have lengthened the volumetric part of the tip, to be able to pipette to the very bottom of microtubes safely, without sacrificing accuracy and precision. Equipped with a high density filter, Diamond tips can play a critical role in applications such as PCR, sequencing, handling of infectious and radioactive samples, and other biological procedures where trace carryover would invalidate experimental results.
A high efficiency filter stops particles down to 1µm. The pore size has been scientifically determined to form an effective barrier against aerosols generated by pipetting.
Gilson has stringent requirements concerning the quality of their moulds and implement very strict controls in order to avoid imperfections.
Gilson Diamond tips have very fine points and improved flexibility.
They are made of pure polypropylene, contain no dyes, and minimal levels of trace metals.
Diamond tips are never handled; they are manufactured by a fully automatic process in a controlled environment.
Diamond tips are also available sterilised and with filters.
Gamma-ray sterilised Diamond tips are delivered with a certificate specifying the date of irradiation.
Diamond filter sterilised tips are certified free of detectable RNase, DNase, DNA, RNA and protease.
They are wrapped in medical-device quality plastic, in order to provide a complete shield against contamination.
