PolyPen Aqua EPA 210

Description

PolyPen-Aqua PA 210 is a portable, handheld and reasonably priced spectrophotometer intended for measuring spectra in suspensions. It can be used favorably in a wide range of applications – biotechnology, limnology, ecology, molecular biology, chemistry, forensic science etc. The device is convenient both for standard laboratory work and for field work, well using its inbuilt GPS unit. The PolyPen-Aqua measures absorbance and transmittance spectra based on a single beam method; detection range is 380 – 790 nm. The device is equipped with an internal light source – Xenon incandescent lamp.

PolyPen-Aqua can be used as an autonomous instrument. It is powered by an inbuilt Li-Ion rechargeable battery and thus it does not require a PC or any other bulky accessory for its operation. Measured spectra are instantly displayed in graphs or data sheets on the device touch screen. Full spectra information is stored in the device memory for later re-analysis in a PC. The important part of the PA 210 package is the control software. It allows user-friendly, online control of the device as well as measured data saving, uploading and further processing in a PC. Definition of custom calculated parameters based on measured spectra is also possible.

APPLICATIONS:
Qualitative and quantitative analysis of liquids and solutions
Growth monitoring of autotrophic and heterotrophic microorganisms
Vital spectra of cell suspensions
Pigment composition
Protein analysis
POLYPEN-AQUA MEASURES:
Absorbance spectrum, calculated using following formula
A=log(I0/I)
I0 is reference light intensity and I is measured light intensity
Transmittance spectrum, calculated using following formula
T= I/ I0
I0 is reference light intensity and I is measured light intensity
Optical density measurement at 600 nm, 680 nm, 720 nm, and 750 nm
Custom defined calculation
SOFTWARE:
