Spectra/Chrom® CF1 Fraction Collector
CF-1 Fraction Collector can be operated as a simple
fraction collector, where each fraction is the same
size and the fraction size is set in terms of time,
drops, or external events (like counts from a pump).
A simple command entered from the membrane keypad enables
the internal peak detector. This allows you to collect
only those peaks of interest from the chromatogram and
to discard the rest.
- Collects up to 174 fractions
- Cold-room compatible
- Tube sizes from 10 to 28 mm diameter
- Built-in peak separator
- Includes drop counter
- 10 time windows
- Can be controlled remotely
- CE Certified
- Collect from 4 columns simultaneously

Spectra/Por® Biotech RC Dialysis Membranes
- Regenerated Cellulose (RC) Dialysis Membrane Tubing
- Ultra high purity
- No special precleaning required
- Precise MWCO
Spectra/Por® Biotech CE Dialysis Membranes
- An Ultra High Purity and Precise Separation Dialysis
Membrane
- 14 precise MWCO's ranging from 100 to 1 million
Daltons
- Hydrophilic and uniform pore size dialysis membrane
- No special chemical precleaning require
Spectra/Por® Biotech Dialysis Membranes Polyvinylidene
Difluoride (PVDF)
- High organic solvent resistance
- Supplied wet in 0.1% sodium azide preservative
Spectra/Por® Standard (1-7) Regenerated Cellulose
(RC) Dialysis Membranes
- This series of membranes are composed of cellulose
regenerated from cotton linters. Spectra/Por Regenerated
Cellulose membranes carry no fixed charge and do not
absorb most solutes. The standard RC dialysis membranes
are used for general laboratory dialysis functions,
i.e. desalting, buffer exchange, or molecular separation.
Spectra/Por 1 through 6 also contain small amounts
of impurities which are easily removed by washing.
It is advised to wash the membrane in Spectra/Por
Heavy Metals Cleaning Solution and/or Spectra/Por
Sulfide Removal Solution when the material to be dialyzed
is sensitive to these contaminants
