Roti-Spin MINI 10 kDa, 96 pcs, Centrifugal devices, 96 unit(s)

For purification and concentration of biomolecules and for purification of solutions.

Type:

• ROTI®Spin MINI: 1.5 ml sample tube for up to 500 µl sample
• ROTI®Spin MIDI: 15 ml sample tube for up to 5 ml sample
• ROTI®Spin MAXI: 50 ml sample tube for up to 15 ml sample

Centrifugal filters for ultrafiltration of biomolecules. The membranes made of highly chemical-resistant polyethersulfone have been tightly sealed to prevent leakage and loss of samples. Furthermore, the membranes underwent special treatment minimising the binding of biomolecules, in order to optimise sample recovery rates.

ROTI®Spin Centrifugal filters can be applied to a variety of applications and can be used to replace tedious and labour-intensive methods like gel filtration, gel purification or precipitation. Application is time-saving and very simple - only few centrifugal steps are necessary to concentrate and recover your sample. During this, the sample remains untouched in the upper reservoir, and cross-contamination is efficiently prevented even when large numbers of samples are handled.

Application examples

Desalting or buffer exchange following restriction digest, PCR or such; separation of free nucleotides and polymerised DNA; removal of contaminating compounds (like DNA) from stock solutions (e.g. PCR-buffers); concentration of DNA or proteins; separation of proteins of different size; sample preparation prior to HPLC.
