Pumps, Valves & Liquid Handling
The Easy Dosing Pump for Aggressive and Corrosive Liquids
Dosing very aggressive and corrosive liquids in laboratories is a challenge. Diaphragm pumps are the ideal tool for this difficult task. The new SIMDOS® 02 FT (PTFE) from KNF has been especially developed for the transfer of aggressive chemicals. To do this, the SIMDOS® 02 FT is fitted with a PTFE head, a PTFE-covered diaphragm, and chemically resistant FFKM Kalrez® valves. An optionally available Chemraz®-valve kit even allows using the pump with highly concentrated acids such as nitric, sulphuric and hydrochloric acids and solvents such as TFH, DMF, DMSO and MEK. The pump head is situated outside the splash-protected IP-65 housing, providing a very significant safety feature.
Also available with heads in PP or PVDF, the new SIMDOS® 02 FT dosing pump transfers liquids with a flow rate of 30 µl to 20 ml/min, and dose volumes of 30 µl up to 999 ml. Following calibration, repeatability is +/-1% (full range) and the pump offers excellent long-term stability and consistent reliability throughout entire processes. The SIMDOS® 02 FT is safe to run dry and is self-priming up to 2 m. It is effective against pressures of up to 6 bar and transfers viscous media up to 150 centistokes. The integrated software permits the transfer parameters to be modified for a range of different viscosities at the touch of a button. Thanks to its neat design and small footprint, the new SIMDOS® 02 FT dosing pump takes up very little valuable laboratory space.
SIMDOS® 02 FT highlights include: FT head / FFKM valves for aggressive and corrosive liquids; intuitive operation; fast and simple calibration; pause function without data loss; adjustable transfer parameters; splash-protected design for increased safety; minimal footprint.

New Vacuum Controller Automates Workfl ows and Saves Time
Vacuum is required in many chemical processes, as sensitive sample materials cannot be heated to any desired temperature. Pressure is often the decisive control variable for gentle and time-saving process control without causing sample degradation. To ensure that the correct vacuum process settings can be made as quickly and easily as possible, all Vacuubrand pumping units are equipped with the new VACUU·SELECT® vacuum controller.
The user interface is specifically designed for lab applications. Predefined vacuum processes are available for all common applications, such as rotary evaporators, vacuum drying cabinets or centrifugal concentrators. The user does not have to deal with an unnecessary number of settings. Instead, the relevant parameters for his process are displayed and can be adjusted as required. Process control (e.g. evaporation at the rotary evaporator) is performed automatically at the push of a button. The user can focus on his research and does not have to continuously monitor the individual steps. Recurring, user-specific vacuum processes can be stored in the favourites menu and are immediately ready to be used at any time. This simplifies work, saves time and ensures reproducible processes and results.
The touch screen display works perfectly even with thick safety laboratory gloves and is based on modern smartphone design, and enhanced to withstand the aggressive chemicals found in modern labs. The intuitive navigation allows immediate use of the vacuum pump without lengthy instruction. Context-related information on applications and settings can be accessed directly via the integrated help function. Users can virtually forget about the vacuum process and devote their attention to other tasks.

ilmt.co/PL/dDj9 Improving Ergonomic Pipetting in the Lab
Integra Biosciences is dedicated to developing innovative solutions to improve ergonomic pipetting in the lab, helping you to avoid repetitive strain injuries (RSIs). Prolonged manual pipetting is an occupation that puts you at risk of developing hand, neck and shoulder injuries, including carpal tunnel syndrome, tendonitis, tenosynovitis, and tennis elbow. Integra supplies a wide range of electronic and manual pipettes suited to various applications, all designed to reduce the risk of RSI and generally improve lab workers’ wellbeing and productivity.
Integra’s ergonomic pipette range includes: EVOLVE manual pipettes - lightweight with low plunger force, offering three separate dials for quick volume changes to avoid the typical approach of twisting the plunger; VIAFLO/VOYAGER electronic pipettes - one-button plunger control and an intuitive thumbwheel design that reduces the risk of thumb injury; ASSIST and ASSIST PLUS pipetting robots - affordable automation of repetitive manual tasks to eradicate ergonomic problems altogether; VIAFLO 96/384 electronic pipettes - fill/mix an entire plate at a time to dramatically reduce the time spent pipetting, with a computer-controlled plunger and electronic tip loading and ejection; GripTip pipette tips - snap effortlessly onto the pipette with no hammering on required, providing the lowest ejection forces on the market.
Read Integra’s article on why you should care about ergonomic pipetting, and take the risk assessment test to see how your lab compares to the optimal pipetting situation. More information online:

Positive Pressure Manifold for SPE Offers Consistent Flow Control for Improved Results
Gilson announces the introduction of the ASPEC® Positive Pressure Manifold for solid phase extraction (SPE). The ASPEC manifold offers an initial step to SPE automation for clinical, forensic and food or beverage testing laboratories. With the ability to accommodate 96-well SPE plates, the ASPEC manifold is also an ideal choice for sample cleanup prior to LC-MS for bioanalysis. The ASPEC Positive Pressure Manifold uses positive pressure gas to force viscous samples into SPE cartridges, unlike traditional SPE vacuum manifolds. The multiple adjustable flow rates improve consistency among samples and recoveries, and ensures uniform flow for both low- and high-viscosity solutions.
The ASPEC Positive Pressure Manifold, with its single gas input and small footprint, incorporates easily into laboratory workflows and provides a fast and simple way to prepare several samples in parallel for later analysis by chromatography. The universal design of the ASPEC Positive Pressure Manifold makes it compatible with popular formats, including 1, 3, and 6 mL SPE tabbed and tabless cartridges and 96-well SPE plates. When combined with Gilson’s PLATEMASTER® microplate pipetting device, the ASPEC Manifold greatly increases sample preparation throughput to meet increased testing demands in the clinical, forensic and food or beverage laboratories.
