Tamson is manufacturing a CEC L-109-14 bath!

Tamson is manufacturing a CEC L-109-14 bath!

Tamson is manufacturing a CEC L-109-14 bath. The CEC L-109-14 test method covers the oxidation test for engine oils operating in the presence of biodiesel fuels. The Tamson CEC L-109-14 bath is a bath with all the accessories to perform tests according to CEC L-109-14. The apparatus consists of a six position TC40 circulator bath and it is standard delivered with six sets of glassware (500 mL flask and condenser).

Recently, we delivered the first bath in Indonesia. We will launch a complete test set-up soon.

Tamson TV7000LT

Tamson is proud to have built two more TV7000LT baths. Those precision instruments will be used in metrological institutes in China and in Uzbekistan.
Both baths will be used for calibration purposes at sub-zero temperatures.On the picture below, the baths have just been tested.
TV7000LT
The history of the TV7000LT goes back many years. In the early seventies a similar system was made by Tamson with a built-in cooling system.
The temperature control was based on a mercury contact thermometer and the refrigeration on an off-shelf conventional cooling system. This design resulted in this big apparatus.
In this apparatus, you will see a high temperature viscosity bath standing on the cooling unit. Back in the seventies, temperature control was still done by using the mercury contact thermometers, instead of the PT100s that became in use later.
First TV4000LT
The minimum temperature was restricted to -20 degrees Centigrade and the immersion depth dept was limited to 300mm. In 2005 a new system was developed upon request for the French national laboratory in Paris.
This unit was based on a TV7000 system and with 600mm it doubled the original immersion depth. This new bath was called the TV7000LT  TV stands for Tamson Visibility bath, 7000 to indicate a volume of 70 Liters, and LT stands for Low Temperature.
This bath more looks like the bath we produce nowadays.
TV7000LT 2005
The cooling system was redesigned to reduce the energy consumption significantly. The cooling system is based on a two mode principle, where the cooling down of the bath goes fast, and once the bath reaches the setpoint temperature, it switches to a mode where less power is used.
It also enables the use of the bath over a much wider temperature range, ranging from -40 up to +100 degrees Centigrade. However, when using the TV7000LT at a wide range, you have to consider the bath fluid that you are using.
For temperatures down to minus 20 water glycol mixtures are popular. For lower temperatures ethanol (or methanol) can be used. When working close to 100 degrees Celsius, silicon oil has to be used, because water does evaporate.

The TV7000LT offers excellent temperature stability. This makes it a good solution for all kind of calibration purposes, such as the calibration of viscometers conform ASTM D2162.

Tamson 140 Years!

Tamson 140 Years!

This year, Tamson celebrates its 140th Birthday.

Tamson is founded on 1 April 1878 by Mrs. Tamson in dedication to her husband, Paulus Marinus Tamson. Tamson started as a wholesaler. The company was trading in laboratory equipment in the field of chemistry and physics. By the 1950s, Tamson started the production of thermostatic baths and circulators. During the 190s, Tamson was famous for its catalog, populary called the 'yellow bible', because it was a very thick yellow catalog, full with all kinds of laboratory equipment. During the 1980s, Tamson also launched the TV2000, TV4000 and TV7000 for the first time, which are the predecessors of the modern day TV2000, TV4000 and TV7000. The famous PMT logo is still being used today.

The Tamson team is proud to work for a company which such a rich history that exists for 140 years this year.

ASTM D1480 apparatus available!

ASTM D1480 apparatus available!

Tamson Instruments is proud to present its apparatus for ASTM D1480, the density and relative density (specific gravity) of viscous materials by Bingham pycnometer. The apparatus for ASTM D1480 consists of our trusted TV12, a TLC10-3 cooling circulator, and Bingham pycnometers with holders.

The ASTM D1480 method covers two procedures for the measurement of the density of materials which are fluid at the desired test temperature. Its application is restricted to liquids of vapor pressures below 80 kPa (600 mm Hg) and viscosities below 40 000 mm²/s (cSt) at the test temperature. The method is designed for use at any temperature between 20°C and 100°C. It can be used at higher temperatures. For this test method, The liquid sample is introduced into the pycnometer, equilibrated to the desired temperature, and weighed. The density or specific gravity is then calculated from this weight and the previously determined calibration factor, and a
correction is applied for the buoyancy of air.

The same apparatus can be used with 25mL Bingham Pycnometers for ASTM D1217.
