Whether in research, science and industry: ratiolab® liquid handling products are used in many laboratories worldwide for applications with liquid media. Our broad portfolio offers everything that facilitates the daily laboratory routine: pipet tips, diverse pipet tips systems, serological pipets, pasteur-plast pipets, etc.
The ratiolab® pipet reservoirs made of white polystyrene (PS) are ideal for the repetitive filling of single and multi-channel pipets. Because of the innovative design, these disposable items are both space-saving and stackable. Their broad edges give them a firm and safe stand. They are thus an uncomplicated and clean alternative to reusable reservoirs.
ratiolab® pipet tips are ideal for all commercially available pipets. Their uniform high quality and precision make today‘s pipets fully effective. Together with specially developed Multirack, Refill System and the ratiolab® Multibox with the associated pipet tips in Multitray, they make pipetting much simpler and safe, also in the most sensitive applications. Our pipet tips are perfectly fit for manual or electronic, single or multichannel pipets.
Precision in each and every detail – a guarantee for highest quality.
made of high quality polypropylene
tight fit due to the precisely fitting cone
optimal handling due to the stable shape
guaranteed dust-free due to special ionization treatment
available pre-sterilized or non-sterile
excellent transparency due to high quality surfaces
minimal residual wetting due to the controlled quality of raw materials
excellent volume accuracy due to precise tip orifice
practice-oriented tip volumes
aeroject® tips with special filters made of hydrophobic PE-HD as an aerosol barrier and for protection against contamination
suitable for all commonly used pipet types
This is why ratiolab® pipet tips always provide perfect results.
The ratiolab® Multiracks provide even more time saving, perfect hygienic conditions and simple operation.
the pipet tips are placed on a robust matrix, in an 8 x 12 format for all tips up to 300 µl, and in a 6 x 10 format for tip size 100 – 1000 µl
the tips can be picked up by 1, 8 or 12-channel pipettors as well as by pipetting robots contamination-free and without any hand contact
the Multiracks are durable and steady, and the hinged cover can be opened up to 180°
after work, the Multibox® can be closed firmly by means of a click closure to protect the tips from dust
the Multiracks are completely autoclavable at 121 °C, 20 min
Multiracks are available in sterile and non-sterile packs
ratiolab® Multibox®plus and -ultra/MultiTray® System
The ratiolab® Multibox®plus and -ultra/MultiTray® system simplifies the handling of pipet tips and provide more safety.
MultiTray®, the dust-proof refill packs made of plastics for ratiolab® pipet tips, hold the tips in plastic matrices. Up to five plastic matrices filled with tips are stacked on top of each other in the space-saving MultiTray®. For tips up to 300 µl the matrices contain 96 pipet tips are in the 8 x 12 standard format. All 100 – 1000 µl tips are in a 6 x 10 format on the matrices. The matrices can simply be removed from the Multibox® with the two finger tabs.
The MultiTray® matrices fit securely into the Multibox®plus and -ultra with a soft click. The framework of the Multibox®plus and -ultra provides full support for the MultiTray® matrices – resulting in convenient and safe tip pick-up, even with 8- and 12-channel pipetors. For tip removal the dustproof, hinged cover of the Multibox®plus and -ultra may be opened completely or partially by using the additional sliding mechanism. For cleaning the cover can be removed.
The ratiolab® Multibox®plus and -ultra/MultiTray® system is space and cost-saving. It clearly reduces the amount of waste, and it provides more convenient and safe pipetting and sterilization.
Pasteur-plast pipets render liquid handling simple and safe. Cross-contamination and carry-over simply cannot occur so that tedious clean-ups are unnecessary. In addition, there is no danger of glass breakage with the resulting danger of infectious material escaping. The pasteur-plast pipets are made of transparent polyethylene. They are inert to biological fluids and most acids. The low affinity of the surface reduces the loss of cells and valuable proteins through binding.
soft, elastic bulb
unbreakable – thus reduced risk of glass injury
burr-free orifice for neat, clean and precise dispensing
only externally graduated pasteur-plast pipets with clearly visible embossed graduations
sterile pasteur-plast pipets are gas-sterilized and individually packaged
Aluminium pipet boxes with optimized easy handling in every day´s work. The cylindrical pipet boxes are the best option for autoclaving various glass items with a length from 150 to 480 mm like mixing rods, pasteur-, volumetric and graduated pipets.
