74 Bringing Microplate Innovation to Market
For organisations looking to commercialise technology innovations or companies looking to develop a high quality product with a competitive edge, Porvair Sciences has a long history of successfully helping customers develop new and innovative microplates and microplate equipment. Specialising in microplate technology since 1992, Porvair Sciences has accumulated a wealth of technical and production expertise that have made its custom microplate design and manufacture service second to none.
Academic research groups and commercial companies are able to benefit from a range of proprietary techniques used by Porvair in the generation of custom microplates including polymer ultrasonic welding, plasma surface treatment, co-sintering of polymers / silicas and 'two-shot' injection moulding. Porvair Sciences is also a market leader in the field of moulding ultra-pure plastic materials such as polystyrene, polypropylene and polycarbonate.
Steve Knight, Marketing Director of Porvair Sciences, commented: "Over the last few years we have helped a growing number of enterprising academic and governmental research groups commercialise their exciting microplate innovations. He added: "Our OEM product development work for life science and chromatography companies has also grown. Feedback from these commercial organisations indicates it is our innovative designs, rapid prototyping, application knowledge and automation-friendly high precision moulding capabilities that were key criteria in them selecting Porvair Sciences as a development partner."

Two New Fittings for Conical Ports Introduced
New fittings designed by Diba Industries provide R&D and manufacturing engineers safe stability for conical ports. The tapered 10-32 Cone-Tip Click-N-Seal™ Ultra and 6-40 PEEK™ thread fittings each include reliable mechanisms to handle fluids.
The 10-32 Cone-Tip Click-N-Seal Ultra fitting is pressure-rated for up to 2000 psi (140 bar) with sturdy PEEK construction. It uses a unique method for hand- tightening fittings. The cap clicks when the right torque is achieved, ensuring a secure seal without guesswork or a wrench. It can be used for 1/16” outside diameter semi-rigid tubing such as PEEK™, PTFE, ETFE and FEP.
Diba’s 6-40 PEEK fitting handles pressure up to 500 psi (33 bar) and houses a PEEK ferrule insert and type 316 stainless outer steel case. It can be used as a replacement part for Lee Minstac™, Tinytight™, and Upchurch™ 6-40 Super Flangeless™ ferrules. Diba’s Omni-Lok™ Type S fitting system further bolsters the fitting.
A two-piece ferrule attaches to the outside of the tubing and is surrounded by a stainless steel lock ring with just the PEEK portion of the connection system in the fluid’s path. The ferrule sits in an opening of the fitting, allowing complete thread engagement with the conical port.

New Compact Chilling/Heating Stage for Assay Plates on Robotic Systems
Torrey Pines Scientific announces its EchoTherm™ RIC20 Peltier-driven, compact Chilling/Heating Temperature Stages settable from -20.0ºC to 110.0ºC.
These units are designed for remote controlled applications on robotic systems. Any number of units can be set to any single temperature via a single computer serial port. The unit(s) will continue to run the temperature instructed, even without a hardwire connection, until told otherwise.
The RIC20 Series are compact and designed to take up as little space as possible on a robot platform. The units measure 6.5” (165mm) long by 4.75” (120mm) wide by 3.5” (89mm) tall without a sample block.
Offered as accessories is the broadest variety of precision-made aluminium sample blocks available anywhere for standard assay plates, deep-well assay plates, centrifuge tubes of all sizes, vials, and most any size test tube. Custom sample blocks can be made for any sample container by request.
The RIC20 Series can be set to 0.1ºC and control temperature to ±0.1ºC. Temperature settings are stable to ±0.2ºC and accurate to ±0.5ºC. Each unit comes complete with chiller/heater module, universal power supply, AC line cord for the country of use, and instructions including the Serial Port Command Set.
The EchoTherm™ RIC20 Series units are UL, CSA, and CE compliant. New Surfactant Electrode Introduced
Sentek, the only UK manufacturer of electrochemical sensors, have followed up their increasing success in the world market, by introducing a combination surfactant electrode, together with a mono version for those who prefer the two electrode system of measurement.
These electrodes have been developed in Croatia as a joint venture between a major university, and a large manufacturing company whose products require surfactant measurements to be carried out.
They have been successfully used for over 2 years, and Sentek have entered into an agreement whereby the manufacturing of the electrode will be a joint venture between the Sentek factory and the university.
Sentek will be responsible for the sales and marketing of these probes worldwide, and already, a lot of interest has been shown by Sentek distributors, who are impressed with the features of the probe, and also its competitive price.
The probes can be supplied with whatever plug the customer requires, and this should be specified when ordering.

Dr Roz Baudry, Senior R&D Chemist at Parogle commented "A magnetic stirrer is fine to make organic molecules, but most of our polymer solutions are too viscous and require using an overhead stirring system.”
She added “We evaluated a range of commercially available multiple position stirred reaction systems before selecting the Asynt Vortex as it incorporated a powerful overhead stirrer and did not require any exotic glassware. Our Vortex systems are used to synthesise branched, grafted or linear polymers in batch or semi-batch processes.
They have proven to be very efficient tools for synthesising compounds for polymer screening. We particularly like that the Vortex is very easy to set-up, use and has proven very robust even with the extensive workload at Parogle Technologies."
The Asynt Vortex overhead stirrer system allows three reactions to be stirred simultaneously using a single overhead stirrer and heated to temperatures up to 200ºC.
The ability to perform multiple reactions in parallel enables the Vortex to improve efficiency. The compact Vortex overhead stirrer system is designed to agitate even the most viscous solutions and can be placed on any hotplate stirrer to heat reactions.

Efficient Tool for Polymer Screening
Vortex Overhead Stirring Systems from Asynt Ltd have helped Parogle Technologies improve the efficiency with which they synthesise novel dendritic vinyl polymers using solution or emulsion free radical polymerisation reactions.
Parogle Technologies, formerly Hydra Polymers Ltd, was formed in 2007 as a spin-off from Unilever plc to provide products derived from dendritic vinyl polymer technology including methacrylic, styrenic and polyurethane systems.
Parogle Technologies exploit the structure and novel 3D shape of their polymers to provide products with superior properties in a wide variety of applications from paints and lubricants to pharmaceuticals and cosmetics.
