New automated viscosity system available: TV4000AKV EASY!

New automated viscosity system available: TV4000AKV EASY!

Tamson is excited to announce the new TV4000AKV, replacing the TV2000AKV. The modular TV4000AKV EASY is a measuring system that includes everything you need to take precise and reproducible automated kinematic viscosity measurements. The TV4000AKV EASY is supplied with a single automated measuring channel. Filling and cleaning of the viscometer must be done manually. The AKV EASY is operated by a user-friendly touch screen and is capable of measuring the kinematic viscosity of samples that are suitable for Ubbelohde viscometers. This includes samples such as formulated oils, lubricants, diesel, hydraulic oils, additives, base oils, light fuels, waxes, crude oils and glycols. Eight different viscometers can be programmed in the system and up to 254 results are saved in the database and can be printed at any time. Each result consists of up to 99 runs. These runs can be done sequentially without interference from the user. The maximum time between two sequential runs is four hours. This allows the customer to test how the viscosity changes over time. The system determines the best repeatability from the measuring runs and supports calculation of the dynamic, relative and intrinsic viscosity. Optionally, the TV4000AKV EASY can be equipped with two measuring channels (dual channel). End of 2020, Tamson will introduce a single measuring channel equipped with a semi-automated cleaning module. The system will rinse the viscometer with the manually inserted cleaning solvent.

Application

The TV4000AKV EASY is ideal for users that don’t run a lot of different samples in a day but also don’t want to do labor intensive manual determinations and it reduces operator to operator variability. The great advantage of the AKV EASY is that the system is flexible. Up to eight custom-made test configurations can be predefined. This allows users to adapt the system to their requirements. The number of runs, preheating time, maximum flowtime and acceptable deviation of flow time are examples of variables that can be preset.

Upgrade kit for installed base

Thousands of TV2000MKII, TV4000MKII, TV4000DC and OEM baths are used worldwide. For these baths, there is an upgrade kit available which makes it possible to upgrade the manual Tamson viscosity bath to an automated system using the AKV EASY.

TV2000AKV discontinued

With the introduction of the TV4000AKV EASY, production of the TV2000AKV has been discontinued. We can only supply our remaining stock. In case you have an actual project for a TV2000AKV, please contact us to discuss the possibilities. We will continue to support TV2000AKVs used in the field.

Tamson presents ASTM D1384 apparatus!

Tamson presents ASTM D1384 apparatus!

New Corrosion bath for ASTM D1384

Recently, we launched a CEC L-109-14 oxidation bath. Based on this design, a valued customer in the USA asked Tamson to modify the oxidation bath, so that it can be used for ASTM D1384 tests.
 
The ASTM D1384 test method covers a simple beaker-type procedure for evaluating the effects of engine coolants on metal specimens under controlled laboratory conditions. In the test method, specimens of metals typical of those present in engine coolant solutions are totally immersed in aerated engine coolant solutions for 336 hours at 88°C (190°F). The corrosion-inhibitive properties of the test solution are evaluated on the basis of the weight changes incurred by the specimens. This test method will generally distinguish between coolants that are definitely deleterious from the corrosion standpoint and those that are suitable for further evaluation.
 

Tamson ASTM D1384 bath

Tamson Instruments is providing a six position bath for this ASTM D1384 test. The robust and well insulated apparatus is delivered with six sets of glassware. Stand-rods with clamps to hold the glassware in the same position, six flowmeters, and tubing are included in the apparatus. Other accessories required for this test method are supplied by Tamson as well. The first apparatus will be shipped this month to the USA.
 
Primary benefits of using Tamson ASTM D1384 apparatus:

- Equipped to hold up to six 1000 mL glass containers

- Levelling platform can be adjusted to line up the height of the bath fluid level with the 1000 mL glass containers

- Large enough reservoir to keep the bath temperature stable during the entire period of sample heating

- Very precise temperature control (better than ±0.02°C)

- Metal parts made from stainless steel - Bath is equipped with a pump to circulate the bath medium to an external application when not used for ASTM D1384 tests

- Bath can be safely emptied using the bath drain - Brackets to hold up to six flow meters

- Complete apparatus for six positions

- ASTM D1384 container is all made from glass, hence no rubber stopper is used. A rubber stopper can crack over time, and the construction would be more fragile.

Tamson ASTM D5853 constant temperature bath

Tamson ASTM D5853 constant temperature bath

The ASTM D5853 test method covers the determination of the pour point temperatures of crude oil down to -36°C. In this test method two procedures are described to measure the upper (procedure A) and lower (procedure B) pour point of crude oil. The maximum and minimum pour point temperatures provide a temperature window where a crude oil, depending on its thermal history, might appear in the liquid as well as the solid state.

Tamson has been asked by its distributors to develop a bath for the mandatory, preliminary heating of the crude oil samples. The TC16 oil bath is used to preheat the sample in the pressure vessel at 105°C. The cover of the oil bath has six openings, each opening comes with a lid and hook for suspending a pressure vessel. The TC16 temperature range is from ambient +5°C to 250°C. For procedure A and B, an additional TC16 water bath can be used to preheat the sample in a pour point glass jar at 48°C or at a temperature 12°C higher than the expected pour point, whichever is higher. For this application a special stainless steel holder with insulated handle can be used to insert the pour point jar in the water bath. Optional is a cover with nine openings to test up to nine samples. Please see our specification sheet for more information. After preliminary heating, the test specimen is cooled at a specified rate and examined at intervals of 3°C for flow characteristics. The lowest temperature at which movement of the test specimen is observed is recorded as the pour point. The test method prescribes a manual procedure to measure the pour point. Tamson also supplies a single adjustable pour point bath with all describes accessories for this method. Please see the separate D97 and D2500 specification sheet.

Primary benefits of utilizing the Tamson ASTM D5853 constant temperature bath:

Tamson ASTM D3231 bath now available

Tamson ASTM D3231 bath now available

Tamson is proud to announce the production of an ASTM D3231 bath!

The ASTM D3231 test method covers the determination of phosphorus in gasoline. Organic matter in the sample is decomposed by ignition in the presence of zinc oxide. The residue is dissolved in sulfuric acid and reacted with ammonium molybdate and hydrazine sulfate. The absorbance of the Molybdenum Blue complex is proportional to the phosphorus concentration in the sample and is read at approximately 820 nm in a 5 cm cell. Phosphorus in gasoline will damage catalytic convertors used in automotive emission control systems, and its level therefore is kept low.

Tamson ASTM D3231 constant temperature bath

For this test method, Tamson supplies a constant temperature bath as described in section 5.2. The prepared samples are transferred to 100 mL volumetric flasks. These flasks are placed in a constant temperature bath for 25 minutes between 82.2 °C and 87.8 °C (180 °F to 190 °F). The Tamson D3231 apparatus comes standard equipped with a levelling platform with a rack to hold up to eight 100 mL volumetric flasks submerged exactly to the mark during the entire period of sample heating.

January 2020 newsletter/TLB50 D86 sampling bath

January 2020 newsletter/TLB50 D86 sampling bath

Tamson ASTM D86 Sample Preparation Bath

A common issue with ASTM D86 distillation tests is that gasoline samples are run immediately after Reid Vapor pressure tests while the sample is still at 0-1°C (32-34°F) and not at the specified temperature of 12-18°C (55- 65°F).

The problem occurs when the test results reflect abnormally high recoveries, for example 99.8% on winter blends of gasolines. The abnormally high results are often caused by charging at the wrong sample temperature (0- 1°C or 32-34°F) and collecting at a receiver chamber temperature of 12-18°C (55-65°F). Proper sample conditioning prevents these errors and faulty test results.

Because of this problem, Tamson presents the TLB50 D86 sample preparation bath for storage or conditioning below 10°C (50°F), as required for group 1 and group 2 samples. The TLB50 D86 bath is equipped with a levelling platform that offers space for up to 12 bottles of 1L each. Also, the TLB50 is equipped with bottle holders that prevent the floating and movement of bottles in the bath.

The TLB50 has an operating range of -5°C up to +80°C. The benchtop bath with integrated cooling can replace the combination of a water bath with an external cooling circulator. This not only saves bench space but also costs because of its high cooling efficiency. The primary use of the TLB50 is sample preparation. Before most samples are analysed they must be conditioned to a specified temperature as described in a test method.

The TLB50 can be used for any test method which require sample preparation prior to the test, like ASTM D323 (Reid Vapor pressure).

Primary benefits of utilizing the TLB50 for ASTM D86 sample preparation:

  • -  Group 1 and group 2 compliance

  • -  Faster time to temperature than a refrigerator

  • -  Improved temperature stability

  • -  Replicate sampling

  • -  Intrinsically safe

  • -  Confidence in temperature consistency

  • -  Much less expensive than C1D2 compliant explosion-

    proof refrigerators
