New from Fritsch: fine and powerful cutting mills with maximum flexibility
T
he new Universal Cutting Mills from Fritsch are ideal for size-reduction for a wide range of different materials due to variable adjustment of the rotational speed of the rotor, various knife geometries, replaceable blades, practical sieve cassettes, together with an unmatched ease of cleaning. Variable 300-3 000rpm for fine comminution The high-speed Universal Cutting Mill Pulverisette 19 comminutes up to 60l/h of soft to medium-hard sample materials and fibrous materials at a torque of up to 30Nm with reliable reproducible results. The great advantage: the variable rotational speed
New 1200 GenoLyte homogeniser and cell lyser from SPEX SamplePrep
T
he 1200 GenoLyte is the ideal solution for applications involving sample preparation for DNA/RNA and protein extractions. It is specifically designed for rapid cell disruption, cell lysis and tissue homogenisation through bead beating. The GenoLyte can also be used to grind harder materials such as soil, rocks and minerals. Features: • Interchangeable sample vial holders allowing for vial types from 2mL to 12mL • Sample homogenises in seconds with the high-intensity oscillating motions • Programmable control panel with rate, run, time and pause functions • Four speeds over the 750-4000RPM range • Safety interlock stops motor if the lid is opened during homogenisation • Clear lid for viewing sample homogenisation process.
adjustment in increments of one hundred between 300 and 3 000rpm enables fine tuning of the comminution process for each sample within a very wide range of applications.
thermal damage, the loss of highly volatile substances, or an excessively high fine share need to be avoided.
Variable 50-700rpm for powerful comminution The low-speed Universal Cutting Mill Pulverisette 19 with variable rotational speed adjustment between 50-700rpm and a torque of up to 67Nm enables, due to the combination of low cutting rate and extreme cutting forces, a very powerful comminution of hard, tough-elastic samples and small sample quantities. At the same time, it is the ideal solution for all cases where, for example,

Weigh small samples and save costs

aboratories need to ensure that expensive, rare or toxic substances are used sparingly in order to reduce waste and save costs. Mettler Toledo’s innovative Excellence XPR MicroAnalytical balances simplify sample handling and allow one to weigh very small sample quantities directly into large tare

containers with a high degree of accuracy. This ensures the efficient use of valuable samples, using an USP minimum weight of 1.4mg and minimises sample waste.
Detect electrostatic charges For very small samples, electrostatic charging can significantly influence the recorded weight value. StaticDetect technology automatically detects static charges on samples and containers and provides a warning if the measured error exceeds predefined tolerances.
Less sample transfer Dosing directly into a tare container avoids the tedious back-weighing and recalculation processes associated with sample transfer, for example, using weighing paper.
Ensure compliance with built-in functions Integrated quality assurance functions such as StatusLight, LevelControl and GWP Approved work actively to ensure accurate weighing results and data integrity.
Fast and stable results The SmartGrid weighing pan significantly reduces any air turbulence on the weighing cell. Stabilisation time is shorter and results are faster, which is beneficial when working in a fume cupboard.
