How can I make my fluidic system more sustainable?

Tags: , , , |

Instrumental analysis may use resources that are limited and chemicals that have negative environmental impact. By constructing fluidic systems to deliver accurate and consistent results with low variability, we help to ensure that the number of repeated analyses can be reduced to a minimum, thereby improving the overall sustainability of the procedures. In the video interview below, Dr. Fritiof Pontén, CEO of Biotech Fluidics, outlines how to design high quality fluidic systems with improved sustainability. This was recorded by LCGC International at the exhibition Analytica 2024 in Munich, Germany. For example, Dr. Pontén describes how the choice of fittings

IDEX Catalogue update 2024

Tags: , , , , , , , |

As the Global Premium Distributor for IDEX, Biotech Fluidics can present an updated IDEX catalogue with flow components, separation tools, and fluid management products. The catalogue has been thoroughly updated and corrected, and all obsolete items have been highlighted or removed. Nevertheless, it is still filled with plenty of fittings, connectors, valves, column hardware, and tubing for construction and maintenance of high precision fluidic systems. As always, Biotech Fluidics is ready to assist you and answer questions about what items would be most suitable for your current fluidics project. Learn more

How can I find Upchurch Scientific fittings and connectors?

Tags: , |

The Upchurch Scientific brand and the Upchurch fittings has since 1975 been synonymous with the most innovative connection systems for the demanding requirements in HPLC and other fluid handling instruments for liquid chromatography and related techniques. The innovations emerging from their location in Oak Harbor (Washington, USA), included for example the immensely popular F-120 One-Piece Fingertight™ PEEK fittings for 10-32 coned ports. Other product highlights include the Flangeless™ and Super Flangeless™ fitting systems that eliminates tedious and time-consuming tubing flanging to accomplish leak-free connections of fluoropolymer tubing in 1/4-28 flat-bottom ports. Since 2004, the Upchurch brand is part of

Tubing kits for dissolution testing

Tags: , , , , |

Did you know that Biotech Fluidics custom manufacture tubing kits for dissolution testing equipment and for other purposes? In pharmaceutical dissolution testing, the solution into which the medication is gradually dissolved, is sampled repeatedly over a certain time period at standardised conditions, to determine the rate of release of an active ingredient. Instruments for these tests are typically designed to perform several parallel experiments in separate vessels. Although sampling could be performed manually, automatic sampling and analysis allow for considerably increased throughput. Automatic sampling typically requires multiple transfer lines to be connected to each vessel for sample withdrawal. This may

New periodic table of fittings

Tags: , |

The poster ‘Periodic Table of the Analytical Fittings’ is available in a new updated version. This very useful visual overview poster presents a wide range of fittings for analytical liquid handling systems in a structured and comprehensive layout (inspired by the periodic table of elements). Here you can get quick information about suitable fittings for a certain port design, for a certain tubing size, and for a certain pressure rating. Each of the 117 fittings are presented with clear information about suitable ferrule combinations and material details, with an indication if any tools are required to tighten the fitting,

Intuitive click fitting

Tags: , |

Intuitive click fitting for low pressure applications Are you dreaming about trouble-free and consistent low-pressure tubing connections? Would a fitting providing this facilitate your laboratory life? Especially in locations where you frequently exchange fluid path components, such as flash columns, in-line filters or eluent bottles? The new Intuitive™ fitting system with its patented self-adjusting torque-limiting nut for low pressure applications, provides a haptic feedback click when it has been sufficiently tightened. You never again have to worry about leaking connections, nor about overtightening and squeezing tubes or damaging ports. The click feedback is built to work for at least

Popular one-piece fingertight fittings

Tags: , |

The original One-Piece Fingertight Fitting was introduced almost 30 years ago and is still one of the most popular fittings offered by Biotech Fluidics for making liquid chromatography fluid path connections of 1/16 inch OD tubing to standard 10-32 coned ports in HPLC instruments. This PEEK fitting (F-120) can hold up to 345 bar (5000 psi) and is convenient and very easy to use since the only tool it requires are your fingers to tighten the fitting into the receiving port. It is available in colours of natural, blue, black, green, red, and yellow. This fitting also comes in

Reliable high-pressure connections every time

Tags: , |

Reliable and reproducible fluid path connections is a fundamental requirement for meeting system suitability criteria in chemical analysis performed by high performance liquid chromatography (HPLC & UHPLC) equipment. Poor connections may lead to retention variability and decreased separation efficiency, thus ultimately determining if the analysis will satisfy regulatory demands including pharmacopoeia requirements, or instead fail. Since unreliable analytical results have no value at all and the samples then must be fully reprocessed, a poor fluid connection could even have impact on laboratory economy. MarvelXACT achieves perfect leak-free fluid connections in HPLC & UHPLC by using a combination of innovative

Fittings 101 – A Guide to the World of Fittings

Tags: , |

Welcome to the World of Fittings! In this guide you will learn all about the fundamentals of scientific fluidic fittings, accessories and some basics about HPLC as an analytical technique. You probably know a lot about the subjects in this book, but we have found that there is a lack of a publication that provides an overview of the subject and we believe that this handbook can be useful to you in your professional practice. There is also a glossary that covers common words and concepts in the field of fluidics, to make it easier for us all to

PEEKsil™ tubing with MarvelXACT™ fittings

Tags: , , |

Our bioinert PEEKsil™ tubing with MarvelXACT™ PEEKsil™ connection systems utilize patented MarvelXACT™ fittings for use in the most demanding UHPLC applications. The robust PEEKsil™ tubing has smooth silica glass wetted surfaces and is chemically compatible to organic solvents. Each connection system is individually cut, polished, and manufactured to provide industry leading technology that produces superior chromatographic results. The MarvelXACT™ fitting features torque-limiting technology that is finger tight and provides a haptic “click” feedback when it reaches the optimum torque, assuring a perfect zero dead volume connection every time. The fitting can be connected and disconnected 100+ times. It incorporates
