Porvair Sciences has expanded its range of syringe filters and clear bottomed microplates.
Porvair Sciences has designed a range of syringe filters optimised for what it claims to be 'most applications'.
All Porvair's syringe filters are free from DNA/RNA, DNAse/RNAse and Pyrogen contamination, and there are three new products in the range.
The first, polyethersulfone membrane syringe filters, exhibit a low affinity for proteins and extractables making them ideal for pre-filtration and filtration of buffers and culture media.
The mixed cellulose ester membrane efficiently binds trace proteins making them suitable for filtration of aqueous solutions.
Meanwhile, Porvair's hydrophobic nylon membrane claims to offers excellent chemical compatibility across a wide pH range enabling it to be used for the filtration of either aqueous or organic solvents.
The Leatherhead-based group has also announced that its tissue culture treated clear bottomed microplates are now available in 6, 12, 24 and 96-well formats.
The bottom surface of the microplates is treated to enhance cellular attachment and growth in uniform layers.
This is left clear to allow cells grown on the bottom surface to be viewed using an inverse microscope.
