Turb 430 IR is a new portable turbidity meter from WTW, designed for use in the measuring range from 0 – 1100 NTU/FNU. Fully compliant to DIN EN 27027/ISO 7027, the instrument is optimized for applications demanding high mobility, e.g. drinking water analysis and process control. Having been developed together with the multi-parameter photometers of the pHotoFlex Series, the Turb 430 IR offers a number of innovations compared…
WTW has reworked and improved the premium photometers photoLab S6 and S12. The Reference Beam Technology of the WTW filter photometers can technically hardly be topped, especially by the resulting stability and accuracy of measuring. Therefore the focus of the improvement has been on AQA and IQC functionality and also user defined methods for more indiviudal testing: Reading of results as transmittance in %T Storage of 10…
Looking for a portable but precise conductivity measurement to fulfil USP 27 regulations on pure water? For this purpose WTW, Weilheim, Germany, offers the Cond 340i, a precise hand held conductivity meter. It is a instrument including memory, datalogger and RS 232 interface with all features to perform conductivity measurements for every application. For USP measurements the temperature compensation can be switched off, a spe…
As ISP vacuum pumps do not contain lubricating oil or sealing water resulting in no back-migration of fluid, it ensures clean vacuum. It is light-weight and occupies minimum space because of original design called double wrap scroll. While orbiting scroll makes one turn, the process of suction, compression and exhaust proceeds continuously, resulting in a minimum pulsation which provides less vibration and low noise.…
Application Reagent containers for storing up to 3.5 ml of MagNA Pure LC reagents on the stage of the MagNA Pure LC Instrument. The tubs can be sealed with MagNA Pure LC Tub Lids (small, medium) (Cat. No. 03 004 082 001). Quality The disposable plastics for the MagNA Pure LC Instrument meet stringent requirements: they are free of nucleases and amplification inhibitors (for PCR/RT-PCR), and are guaranteed to be inert to…
