Density Ball, Model 475
For rapid determination of density of liquids. A sphere of volume 100 or
10 ml is immersed in a beaker the contents of which have been previously
weighed. The increase in liquid level given in grams (g) corresponds with 100 or 10 x the value of the density. The equipment is easily cleaned after use.

O2 and CO2 are the gases whose rates of consumption or production are most frequently measured for the purposes of study and process control (energetic metabolism, substract utilisation, etc.).
The measuring ranges of the GA analyser (0÷10 or 15% for CO2, and 21÷10% for O2) have been chosen specifically for your application.
The system is based on wellproven, high quality transducers, and is characterised by an extremely reduced internal volume, to reduce overall response times.

ATI Model Q45D Dissolved Oxygen monitor provides reliable oxygen measurement and reduced maintenance costs. The galvanic dissolved oxygen sensor uses a rugged 5 mil Teflon membrane to resist mechanical abrasions and tears. The membrane serves as a barrier to allow molecular oxygen to diffuse into the reaction cell where it is reduced, producing a small current which is proportional to oxygen concentration. To keep the dissolved oxygen system nearly maintenance free, an optional Auto-Cleaner can be included to remove those materials that build up on the sensor membrane. The cleaning cycle is user selectable to maximize the cleaning effectiveness.

DO stands for Dissolved Oxygen, which is the measure of amount of gaseous oxygen dissolved in a solution. In theory, the amount of DO in a solution is dependent on 3 factors, namely temperature, salinity and atmospheric pressure. The measurement of DO requires a special DO electrode that is made up of an anode, a cathode, electrolyte solution and a gas permeable membrane.

MINIFLASH - The new Age of Flashpoint Testing
MINIFLASH is the only series of instruments for the automatic determination of the flashpoint of liquids and solid samples according to the advanced ASTM D7094 standard. This procedure describes the “Standard Test Method for Flash-Point by Modified Continuously Closed Cup (MCCCFP)”, which offers the highest repeatability and reproducibility and an excellent correlation to the D93 Pensky-Martens method: "there is no statistically significant bias observed between ASTM D7094 and ASTM D93 Procedure A” as concluded during the last Round Robin.
Test results are equivalent to other well known standards such as Abel and TAG, and thanks to its unique design MINIFLASH can be used for more difficult applications such as flash-point testing of contaminated samples like diesel fuel in lube oil or gasoline in diesel fuel and for biodiesel testing.
Its continuously closed cup design and small sample volume of only 2 mL offers maximum safety, avoids offensive fumes in the testing area and reduces sample waste.
Due to the true portability and rugged housing, the MINIFLASH is also the perfect solution for mobile labs and military applications.
Features
* Complies exclusively to ASTM D 7094 and ASTM D6450 (Flash-Point by Continuously Closed Cup)
* Maximum Safety: only 2ml sample, no open flame, continuously closed cup, no offensive vapors
* Excellent Correlation to ASTM D93, D56, ISO2719 (EN/DIN 22719), ISO13736, IP170
* Approved by: US D.O.T., RCRA, NATO and the US NAVY
* Approved for the ASTM specifications of recycled fuel and biodiesel
* The world wide standard in the flavors and fragrances industry

Latest generation of Herzog Flash Point with proven reliability, superior design for Pensky-Martens automated closed cup testing
Designed to save time, money and bench space, HFP 339 Pensky Martens analyzer automatically determines flash point in strict compliance with the appropriate test method. In addition to standard test methods, the HFP 339 may be programmed with user-defined test protocols and test for samples with an unknown flash point. An alphanumeric solvent-proof keypad, large easy-to-read VF-Display and intuitive menu flow provide an exceptionally user-friendly interface.
To increase test productivity on products having an elevated flash point, the HFP 339 begins with an accelerated heating rate and automatically switches to the standard heating rate at the appropriate temperature to assure accurate results. Results are automatically corrected for barometric pressure and displayed on an easy to read HFP VF-Display. The last 9 results are memorized in the unit and can automatically output to an optional printer or computer system (LIM).
