Laboratory Products 39 Accurate Mass Flow Control Improves Vacuum Coatings Results
Alicat Scientific’s mass flow controllers ensure the optimal coating environment in vacuum chambers, maintaining product integrity in coating and sputtering processes. The MCE-Series and MCV-Series may be used to replace legacy and discontinued MKS instruments. Made to fit the same space as common industry mass flow controllers, both series are easy to integrate into existing systems. In use, they offer fast, accurate flow control for process uniformity and quality.
The Alicat MCE and MCV accurately control gas flow rates as low as 0-0.5 sccm full scale or as high as 0-20 slpm full scale with control response times of 50 to 100 milliseconds. Fast response times can greatly improve vacuum coating end products and help eliminate target poisoning. The integrated pneumatic shut-off valve is normally closed, affording positive shut-off of 1 x 10-9 atm-sccm/sec Helium max.
The MCE can be used as a replacement of the legacy Type MKS 1179A Mass-Flo® , while the MCV replaces the discontinued Type MKS 2179A Mass-Flo® Pre-programmed with calibrations for 98 gases, the MCE and MCV measure mass flow, volumetric flow, absolute pressure and temperature, with full
temperature and pressure compensation. Units may be programmed directly through the instrument keypad or remotely via RS-232 (RS-485 also available). The MCE and MCV use patented laminar flow differential pressure (DP) technology found in many Alicat Scientific flow instruments, are supplied with NIST traceable certification, and carry the CE mark.

Alicat mass flow controllers operate on universal 12-30 VDC supply, and Alicat will match any pre-existing pin out on 9-pin or 15-pin D-sub connectors, for easy replacement. The units can be mounted in any orientation, even upside-down, without recalibration, further simplifying installations.
12 Free Tips Help Keep Test Weights Accurate
Mettler Toledo is pleased to present a new article entitled ‘Correct Weight Handling: 12 Practical Tips’. This free guide details actions you can take to protect the accuracy of your test weights as well as actions that should be avoided to preserve precision. Learn these strategies today by downloading the free article at:

Test weights are an indispensable resource for testing and calibrating scales and balances, and they require manual handling. As such, issues such as skin oils, dirt and shifting ambient temperatures can affect their accuracy. When these issues are not addressed, operators may conduct tests with inaccurate weights, resulting in weighing errors as well as costs associated with rework, waste disposal, and product recall.
Fortunately, a simple series of 12 practical strategies including choosing the right storage techniques can help you protect the usable life of your test weights and avoid inaccuracies.

The highly regarded Rotronic HygroGen2 temperature and humidity generator is now available with a large chamber – HG2-XL model
Rotronic is proud to announce the launch of the HygroGen2-XL reference generator, compared with the ground breaking portable HygroGen2-S model, it has a chamber volume that is 10 times larger.
This enables multiple probes from all manufacturers to be calibrated both in the laboratory and on-site. Calibrations can be performed across the working range of devices; with only a few minutes to reach stable set-point equilibrium work is completed quickly compared with other methods.
The HygroGen2-XL generator saves time and money with its ability to perform multipoint calibrations on multiple sensors with fast turnaround time, providing fast payback on the investment.
Features - Chamber volume: 20 litres - Work volume: 17 litres
- Humidity changes (5…95%RH, 0.1%RH stability): <15 minutes
- Temperature changes (23…50°C, 0.01°C stability): < 15 minutes
- AutoCal automated calibration option
- Integrated FDA 21 CFR part 11 compliant Rotronic HW4 software
- Favoured by ISO 17025 calibration laboratories worldwide
Applications
The HygroGen2-XL generator is perfect for calibration laboratories, production areas throughout industry and research facilities where fast stability time is required. It enables a high volume of probes and devices from all manufacturers to be calibrated at multiple points with fast return to their installation minimising production downtime.
Further technical information on the HygroGen2-XL generator and all Rotronic parameters and devices is available on the Rotronic website
