Advanced Cell Density Meter

MicroSpek™ product line provide a series of instruments for life science fields dealing with cell density, DNA, RNA and protein

quantification with unprecedented accuracy.

The product line includes many configurations with models offering both a micro volume sample and industry standard micro-

cuvette based sampling.

We design the best simple easy to use instruments for the life science community.

“Simple Innovation” in everything is what we do.

MicroSpek™ DSM

LAXCO

Fast, accurate, reliable, affordable new concept in Cell Density Meters. .

Ability to measure a cell’s density in micro-volumes and/or cuvettes and tubes.

Low-cost portable unit that can be used in small restricted spaces.

Internal battery allows it to be used anywhere in the lab or taken to the fields.

No user calibration required & Graphical LCD Display.

Noise Compensation Technology for removal of noise in reading.

Features Small footprint, reducing time and cost to result

The DSM series 600nm wavelength light beam is absorbed by the cells as it

passes through, and outputted as a percentage of transmission (%T) or

absorption (Abs). Test yeast, E. Coli and bacteria cultures (not recommended

for mammalian cells) in suspension easily and accurately. The DSM internal

memory will store up to 1000 data points, and can be upload in excel format

to PC software (Part # DSM-SWL-J9004, sold separately).

• Capacitive touch LCD display

• Time lapse, charting, & graphing

• 600nm wavelength LED for E.Coli, Yeast, & Cell counts

• Standalone system & Small footprint

• Reads abs, %T, and McFarland units

• Micro-volume, cuvette or dual reading option

• Works in incubation cabinets, under anaerobic conditions or

in fume hoods and bio safety cabinets
