Designed to replace glass Pasteur pipettes, Pastettes are unbreakable, don’t require a separate bulb and, as they are manufactured from soft plastic, can be recycled. A key property is that they will not pierce the skin – a major worry in the modern laboratory.
Manufactured from virgin lowdensity polyethylene (LDPE), they provide a precise, non-toxic and inert method for transfer, delivery and storage of samples or reagents.
This defines the maximum liquid volume that may be transferred. However, Pastette is just as effective when less than the maximum bulb draw is used.
Manufacturing precision produces a bulb with a uniform thickness. This means that the bulb is strong enough to draw up and hold your sample securely, whilst being soft and even enough to allow sensitive dispensing of single drops of liquid as small as 18µl.
All Pastettes are accurate to ±10% of the stated specifications including drop volume, allowing quantitation without the use of an expensive pipetting device.
An important dimension, it allows Pastette to match your exact requirements. From the shortest (36mm) to the longest (300mm), they all retain the features you would expect from a Pastette.
The design of the tip is of paramount importance as it decides not only the drop volume, but also the procedures for which Pastette may be used. This is why Pastette provides a number of tip styles to cater for a wide variety of applications.
