Microplates specialise in the manufacture of microplate products, and they would also like to mention that they serve Life Sciences, Biotechnology, R&D and Molecular Biology with microplate solutions for all applications.
This includes sample preparation and high throughput screening with its global distributor network.
Porvair Sciences have a range of products which includes everything from – ‘vacuum manifolds, sealers, evaporators and microfilter plates in all popular styles.’ As well as ‘deep well and shallow good storage plates, assay plates, luciferase reporter gene plates and even liquid handling reagent reservoirs.’
The microplates company also provide custom microplate products for life science research, including 96-well SPE sample preparation. They are designed to work with filter plates such as ‘Waters, Millipore, Qiagen, Whatman, GE Healthcare, Varian, Biotage and Porvair.
On their website Microplates, Porvair Sciences has a storage collection that you can browse through. First, you have deep, good polypropylene microplates, which are commonly used for sample storage in life science laboratories. An essential factor to take into consideration with the manufacture of these plates is the selection of clean raw materials for injection moulding.
What is so unique about polypropylene, is that it is an inert and heat resistant material, which is perfect for sample storage. Although all grades of polypropylene are not the same, take for instance injection moulding, grades of polypropylene often have high concentrations of chemicals to aid the moulding process.
This then creates rapid production of plates and lowers costs, at the risk of possibly compromising the integrity of samples or compounds because they are stored in such plates for extended periods.
The problem is acute where compounds are stored as solutions in solvents such as methanol or DMSO, as these excellent solvents tend to extract from the polypropylene base material any added extractable compounds such as mould release agents or polymer flow improvers.
According to the Microplates website, Porvair Sciences has published a detailed analysis of its own and other manufacturer’s plates, with MS traces, so that you can compare good and bad performers.
So, within the storage collection, you have the Deep Well Centrifuge & GeoGrinder accessories, the deep well square, and the deep well round.
Under the Deep Well Centrifuge & GeoGrinder accessories, you have the centrifuge support plate. These are designed to fit into the skirt (the border) of the deep well plates. This then allows the plate to be used in a centrifuge without the risk of the plate distorting, cracking or breaking, causing the well to leak.
For the Deep Well Square, the family of 96-well square plates were designed so that they would make the interchange of plates simpler in automated systems. Interestingly, all of the three plates have the ‘same geometry, and the only variable’ (the part that can be adjusted) is the excellent depth.
Then for the Deep Well Round, the plates are made in virgin polypropylene to minimise extractable. The working volume is 1ml per well, and the total amount is 1.1ml. Coloured plates are highly beneficial as they aid identification when retrieving from storage.
Porvair Sciences Ltd has a long history of successfully helping customers develop new and innovative microlitre plates and equipment.
They also offer quick and efficient solutions to problems from consultancy, design to speedy prototyping for biotech, pharmaceutical and life science companies.
Porvair Sciences, specialists in the manufacture of microplate products, serve Life Sciences, Biotechnology, R&D and Molecular Biology with microplate solutions for all applications, from sample preparation to high throughput screening via our global distributor network.
