Flow meter for very small quantities
Rainin pipette tips enhance your workflow
E
lean pipette tips are critical in liquid handling and research applications to ensure high quality lab results. Pipette tips that come into contact with samples must be free of DNase, RNase, DNA, pyrogens, adenosine triphosphate (ATP), PCR inhibitors, trace materials and trace organics. Understanding these typical sample contaminants, and taking precautionary measures to reduce or eliminate them at their source is vital to protecting sample integrity. Mettler Toledo’s Rainin high-grade BioClean tips ensure top pipetting performance through innovative design and high quality production. Manufactured from virgin polypropylene material in a fully automated, Class 100 000 clean room facility, these flawless tips are 100% contamination-free and ensure absolute purity and safety, preventing experiment inconsistencies and failures. Rainin’s LTS tip range is manufactured with continuous tapering and thin-walled construction to give greater flexibility, a softer feel and a better performance than standard or bevelled tips. Traditional tips are also offered with a conical design to fit pipettes of all standard manufacturers, such as Eppendorf, Gilson, Sartorius (BioHit), Thermo (Finn), as well as the traditional
ven extremely small quantities of low viscosity and translucent fluids can be reliably measured and monitored with an impeller flow meter. Kobold’s flowmeter DPL, specifically designed to measure and monitor liquids, is available from Instrotech. Its compact design is perfect for use in equipment where space is at a premium. Made of high-grade plastic, DPL has a very low wear-rate, as the rotations of the sapphire mounted impeller are sensed without contact, by optoelectronics working with infra-red light. The connection to the process can be made with hose sleeves or ½” connection threads. With an Enclosure Class of IP 65, the DPL flow meters are ideally designed for rough industrial use on site. There is also a choice of five different measurement ranges from 0.025 ... 0.5L/min up to 1 ... 25L/min.
DPL’s significant characteristics: • Linearity: ± 1% • Pressure max: 10 bar; Temp max: 70°C • Viscosity range: low viscous • Connection: G ½ male, hose connector • Material of case: PP • Output: pulse • Without magnets or metal parts • Medium: infrared light transmissive DPL finds application in machinery and plant building. The flow meters are ideal for monitoring or dosing problematic (and even non-conductive) media such as distilled water, fuel, alcohol or special chemical compounds. There are other applications too such as in low viscosity liquids, nonconductive liquids, volume dosing with external electronics, filter aids and the beverage industry. There is a choice of different frequency or analog outputs for measurements. Additional evaluating electronics with analog or digital display or switching outputs round off this comprehensive range. Contact Instrotech for more information on Kobold’s DPL Low Volume Rotating Vane Flowmeter.

Freedom from multichannel pipetting for any lab
A
utomated pipetting is within reach of virtually every lab with the Integra Biosciences compact ASSIST PLUS pipetting robot. This unit is able to automate repetitive processes, such as serial dilutions, reformatting, and set-up of assay plates. There is no need for dedicated personnel or complex programming. Intuitive to use, the ASSIST PLUS pipetting robot utilises Integra’s electronic multichannel pipettes to deliver flexible, reproducible and error-free pipetting. Simply mount an Integra Viaflo or Voyager electronic pipette onto the Assist pipette holder, choose a protocol, add a tip rack and your lab ware.
Press run and the pipetting task will be carried out automatically. New applications are accessed simply by swapping to a different Integra pipette, ensuring the system will never become obsolete, and the pipettes can still be used manually when desired. ASSIST PLUS automated multichannel pipetting offers: • Precise tip positioning in wells • Optimal tip immersion depths • Consistent pipetting angle • Controlled pipetting speeds • No pipetting mistakes • Strict adherence to pipetting programs.
