SPECTRUM manufacture
vast ranges of scientific merchandise together with heating and management
equipments, homogenizers, rotators, shakers, stirrers, vortexers,
and so forth.


Spectra/Chrom® CF1 Fraction Collector
CF-1 Fraction Collector might be operated as a easy
fraction collector, the place every fraction is identical
dimension and the fraction dimension is ready by way of time,
drops, or exterior occasions (like counts from a pump).
A easy command entered from the membrane keypad permits
the inner peak detector. This lets you acquire
solely these peaks of curiosity from the chromatogram and
to discard the remaining.

Fundamental System

Spectra/Por® Biotech RC Dialysis Membranes

  • Regenerated Cellulose (RC) Dialysis Membrane Tubing
  • Extremely excessive purity
  • No particular precleaning required
  • Exact MWCO

Spectra/Por® Biotech CE Dialysis Membranes

  • An Extremely Excessive Purity and Exact Separation Dialysis
  • 14 exact MWCO’s starting from 100 to 1 million
  • Hydrophilic and uniform pore dimension dialysis membrane
  • No particular chemical precleaning require

Spectra/Por® Biotech Dialysis Membranes Polyvinylidene
Difluoride (PVDF)

  • Excessive natural solvent resistance
  • Provided moist in 0.1% sodium azide preservative

Spectra/Por® Normal (1-7) Regenerated Cellulose
(RC) Dialysis Membranes

  • This sequence of membranes are composed of cellulose
    regenerated from cotton linters. Spectra/Por Regenerated
    Cellulose membranes carry no mounted cost and don’t
    take in most solutes. The usual RC dialysis membranes
    are used for normal laboratory dialysis features,
    i.e. desalting, buffer trade, or molecular separation.
    Spectra/Por 1 by 6 additionally comprise small quantities
    of impurities that are simply eliminated by washing.
    It’s suggested to scrub the membrane in Spectra/Por
    Heavy Metals Cleansing Resolution and/or Spectra/Por
    Sulfide Elimination Resolution when the fabric to be dialyzed
    is delicate to those contaminants
