Spectrum is committed to satisfying its global customers by providing quality products and services. Continuous company improvement is the goal of every employee.
Spectrum Laboratories, Inc. is a global leader in membrane separation technologies for the
pharmaceutical, bioprocess, diagnostic and research industries. Founded by CEO, Roy Eddleman,
Spectrum began operations in January 1970. Based in Los Angeles, today Spectrum focuses on
two core technologies, Single-Use Hollow Fiber Tangential Flow Filtration (HF TFF)
and Tubular Membrane Dialysis.
Spectrum's early accomplishments include the invention of cellulosic dialysis membranes
in a wide range of molecular weight cut-off's (MWCO) for the gentle purification of
proteins, desalting enzymes and sample preparation. Commercialized under the trade
name Spectra/Por®, these dialysis membranes and accessories lead the market
with sales in more than seventy countries. Fueled by market demand, Spectrum continues
to develop new and innovative dialysis products.
In 1995, Spectrum initiated production of mixed cellulose ester hollow fiber filters for
the purification and concentration of biopharmacuticals and diagnostic particles.
Since then, Spectrum has successfully expanded this technology and market reach by introducing
a wide range of hollow fiber membrane chemistries and pore sizes for ultrafiltration,
nanofiltration and microfiltration. These KrosFlo® branded membrane filters and support
pump systems are used in a multitude of up-stream and down-stream applications including
point-of use-water filtration, cold sterilization of culture medium, protein purification
and concentration, virus removal and concentration, lysate clarification, bioreactor
perfusion, whole cell diafiltration, as well as many other specialized separation processes.
Spectrum further strives to advance Tangential Flow Filtration technology by developing novel
hollow fiber membrane chemistries. Most recently, Spectrum introduced a hydrophilic and low
protein binding modified polyethersulfone (mPES) hollow fiber membrane that provides superior
flux and higher product recovery.
Corporate headquarters are in Los Angeles, CA, with additional US facilities located in
Dallas, TX, Houston, TX and Las Vegas, NV. International sales offices include Breda,
Netherlands; Paris, France; Brussels, Belgium; Frankfurt, Germany; Loughborough, UK;
Shanghai, China and Otsu, Japan. Spectrum products are also represented and sold
through a network of distributors throughout the world.
