Porvair Sciences manufacture a wide range of microplate products, as well as specialise, as well as serve Life Sciences, Biotechnology, R&D and Molecular Biology with microplate solutions for all applications, for example, sample preparation through their global distributor network. They also manufacture microplate products such as the 96 well plate.

The deep well microplates are commonly used for sample storage in life science laboratories. There is an important aspect associated with the manufacture of these plates, which is the selection of clean raw materials for injection moulding.

They are made of polypropylene, which is an inert and heat resistant material, ideal for sample storage. However, all grades of polypropylene are not the same; for example, injection moulding grades of polypropylene often have high concentrations of chemicals to aid the moulding process. This allows rapid production of plates and lower costs, but may compromise the integrity of samples or compounds which are stored in such plates for extended periods.

With regards to one of the microplates, the 96 deep well plate was designed so that it would make the interchange of plates simpler in automated systems. So, for applications using the GenoGrinder™ and TissueLyzer™, a specially reinforced version of this plate is available with extractable-free, medical-grade molecules called polymer.

The microplate 96 well is specifically for seed and leaf genomic studies, which is an area within genetics that focuses on the analysis of an organism. The microplate 96 well is also:

  • Made from virgin polypropylene
  • Tested for low extractables
  • Tight specification levels
  • It can allow total liquid removal
  • There are no inner edges
  • Manufactured under DNase/ RNase free environment
  • Working volumes of 350µl, 1ml, 1.6ml and 2ml
  • Raised well rims to improve heat sealing
  • It has a conical base
  • Sterile and non-sterile versions

These microplates are made in virgin polypropylene to minimise extractable. Their maximum volume is 2.075 ml per well, and working volume is a useful 1.85 ml, more than any other comparable ‘2 ml Round Well’ plate in this class.

There is a design called the ‘common wall’ which allows the highest possible volume to be used while maintaining an overall height of just 45 mm, complete with ANSI/SLAS standard base and footprint.

Fortunately, Porvair Sciences has developed several storage/collection plates to help in the fields of cell biology, molecular biology, drug discovery, combinatorial chemistry, screening and genomics (an area within genetics).

The plates are manufactured in proper room conditions, and a significant number are DNase/RNase free. They are mainly made from polypropylene, which is inert material giving heat and solvent resistant qualities.

At Porvair Sciences, there is a new range of low profile 1.1ml 96-well round plates. Thus, more plates can be stored or stacked in a given space. As mentioned previously, since the plates are made with extractable-free polypropylene, this, in turn, gives excellent results. Also, there is a specific anti-evaporation cap mat available.

Porvair Sciences offers the most significant combination of excellent shape, several wells and well volume on the market. Each one of the good microplates is in the ANSI/SBS format, this is found on most washers and mechanical equipment.
