SciLog Introduces Single-Use Sensors
SciLog announces inexpensive in-line, sensors for pressure, temperature and conductivity.
These new pre-calibrated sensors have embedded memory and bar code traceability,
and may be used once & thrown away or reused multiple times. Single use processing
with disposable fluid paths is now possible. Service life may be extended through
either sanitization with NaOH or sterilization by autoclaving, ETO, or gamma.
SciLog sensors are easy to use and excellent for aseptic, single-use applications
including chromatography, tangential flow filtration, protein concentration/desalting,
ultrafiltration, reverse osmosis, CIP, aseptic filtration, bag manifolds, direct
flow filtration, and many more. These new sensors are excellent for biotech, food,
dairy and nutraceutical applications.
Calibrations as well as IDs, serial#, lot # are stored in each sensor, easily downloaded
into a spreadsheet or output to a printer. Other useful features include real-time
documentation and graphing of your process with a date/time stamp. High/Low Alarms
can be set, as well as 4 TTL alarm outputs. Certificates of GMP/GLP compliance and
calibration are readily available upon request.
SciLog’s line of sensor technology is available in sizes that include Luer, 3/8”Barb,
½”Barb, ¾”TC, 1”TC, allowing effortless scale-up or scale-down of your application.

Real-Time Measurement of Total Organic Carbon (TOC)
Accurate measurement of water quality is critical to the pharmaceutical production
process. Regulations mandate monitoring of Total Organic Carbon (TOC) levels for
Purified Water, Water for Injection (WFI) and Highly Purified Water. Testing requirements
are defined in the United States Pharmacopeia (USP) Chapter <643> and European Pharmacopeia
(EP) 2.2.44 guidelines.
TOC measurements respond to a broad range of organic compounds. Most TOC sensors
used in monitoring water quality oxidize organics to CO2 in order to detect them
by conductivity. The difference in conductivity before and after oxidation is used
to determine the TOC concentration. In a process environment, response time is critical.
Using Thornton’s 5000 TOC USP <643> compliant Sensor with continuous measurement
technology, organic compounds are measured in real-time, so that excursions in water
systems can be immediately evaluated.
Combine Thornton 5000 TOC Sensor(s) with a 770MAX Multi-parameter Instrument for
an ideal analytical package. The 770MAX accepts one or two sensors and provides
two additional smart channels for conductivity, pH, DO or Ozone measurement. Two
pulsed flow channels are also available.
