Laboratory Products

Just a brief excerpt from our
company’s history
Since 1936 – new impulses from research and development
time and time again
1936 Beginning of development and production of pH glass
electrodes at Jena er Glaswerk SCHOTT & Gen. in Jena.
1940 Beginning of viscometer production using capillaries that
were manufactured in ac cordance with the calibrated
precision glass method that SCHOTT had developed.
1952 Development and production of the first gel-filled,
low-maintenance reference electrodes.
1962 The unique platinum diaphragm makes substantially
faster response times possible, among other things.
1964 Double electrolyte system for reference electrodes.
1970 Introduction of semiconductor preamplifiers for pH
measurement technology.
1972 Buffer solutions in double-pointed ampules sterilized
with superheated steam guarantee reliable calibration –
even after several years in storage.
1972 Plug system from SCHOTT, copied time and again.
1973 SCHOTT Geräte GmbH established as an independant
company.
1973 Beginning of viscometer calibration using PTB tested
reference measurement standards. (German Physical
Technical Institute).
1974 Development and production of electronic laboratory
pH meters.
1975 Market launch of the first automatic viscosity measurement
apparatus for aggressive and corrosive solvents
(AVS/G and AVS/PA).
1977 Development and production of portable electronic pH
meters.
1978 Production start for the first titration control unit TR 155
and the T 100 piston burette with exchange unit.
1982 The first microprocessor-controlled viscosity measurement
apparatus (AVS 300).
1983 Development of the new Type S pH glass for hot alkaline
solutions with extraordinarily high reliability and useful
life, and Type H pH glass, robust and small alkali error.
1984 Combination measurement and reference pH electrode
with integrated Pt 1000 as standard.
– SCHOTT Geräte presents the first thermal scanning
method for viscosity measurment.
– The first stand-alone viscosity measurement apparatus
with integrated computing function (AVS 400 and
AVS 440) are introduced on the market.
– Compact T 80/T 90 piston burettes and simple control
unit TR 85.
1988 Presentation of the first PC-controlled titration system
TPC 2000 at the Achema 1988.
1989 With the AVS 500, the tradition of successful automatic
samplers for determination of the viscosity of aggressive
polymer solutions was continued.
1990 REFERID ® electrodes with polymer electrolyte, lowmaintenance.
1991 Low-impedance Type L pH glass for low temperatures
and ultrapure water.
– Automatic sampler TW 280.
1992 TT electrodes, capable of withstanding up to -60 °C.
