Fast and precise element analysis in organic sample materials Eltra Elemental Analysers – CS-580
E
ltra‘s CS-580 is the ideal analyser for the simultaneous determination of carbon and sulphur in organic samples. Thanks to sample weights from 200mg or more, even inhomogeneous materials can be reliably analysed. The temperature of the powerful horizontal resistance furnace with ceramic combustion tube can be set to a maximum of 1 550°C with a working temperature of 1 350°C, ideal to burn any organic samples. The analyser can be equipped with a maximum of four independent infrared cells according to the user‘s requirements, allowing for a great variety of applications.
New universal and reliable pH meters
M
ettler Toledo’s SevenCompact series combines precise electrochemical measurement technologies with flexibility, innovative design and ease-of-use. The new SevenCompact S210 benchtop pH meter offers fast and accurate pH/mV measurements and is the perfect choice for a wide range of applications within the biotechnology, chemical, food and beverage and academia industries. Intuitive operation Enjoy easy, instinctive operation on the large colour display, giving one the ability to start a measurement or calibration or switch between display modes with just a single keypress.
Automatic buffer recognition The automatic buffer recognition system allows one to choose the order in which to use buffers when calibrating. This enables quick routine calibrations without unnecessary error messages. Secure and full GLP support Ensure perfect sensor calibration through the Intelligent Sensor Management (ISM) function which automatically recognises any ISM-sensor for secure, highly reproducible results. Users that need full GLP support will have peace of mind when employing the full spectrum of security functionalities. Versatile, robust and durable SevenCompact’s robust IP54 high quality
Intelligent evaporation Heidolph – Hei-VAP Core Rotary Evaporator
A
n operating concept that is focused on the essentials: clear and with access to the basic parameters’ rotation speed and heating bath temperature at any time.
•
•
• Features • Clear digital display showing actual and set values • Two separate knobs with dynamic control for setting the rotation speed and heating bath temperature: fast turning for large jumps, slow turning for precise setting of the set values
•
•
Accidental changing of the values can be prevented by the lock function Intuitive LED ring light system makes activated functions clearly visible even from a distance Easy adjustment of the immersion depth up to 160mm and the inclination angle from 20° to 80° Standby function and residual heat warning at heating bath temperatures above 50°C Available as hand or motor lift models.
Application examples Ashes, building materials, coal, coke, gypsum, limestone, oil, plant materials, rubber, sand, soils, soot, tobacco, waste, and more.
