This chemistry vacuum system provides the advantageous combination of high pumping speed and low ultimate vacuum down to 70 mbar. It is therefore ideal for evacuating and pumping large amounts of gases and vapors. It has a wide range of applications in chemical, biological and pharmaceutical laboratories if condensation of solvent vapors at the outlet is not necessary. Typical applications are vacuum ovens, single and multiple filtrations, as well as concentration of solvents with low boiling points. The separator at the inlet (AK) is made of glass with protective coating and retains particles and liquid droplets. The separator at the outlet collects condensate, avoids condensate backflow towards the pump and makes the pump whisper-quiet.

• outstanding chemical resistance and superior vapor tolerance
• high performance even at low vacuum levels
• compact design
• whisper quiet and very low vibration
• separators at inlet and outlet to collect condensates

• low vibration
• long diaphragm life, maintenance-free drive system

One-stage diaphragm pumps are an excellent solution for continuous, oil-free pumping of gases and vapors at low vacuum requirement. In contrast to waterjet pumps they do not consume water and therefore do not produce any contaminated waste water in daily use. Typical applications are vacuum ovens, filtrations and multi-port manifolds for medium throughput, as well as pumping of gases and oil-free evacuation in general. The one-stage construction provides the advantageous combination of high pumping speed and low ultimate vacuum down to 70 mbar.
Performance features
• whisper quiet and very low vibration
• powerful, even for parallel operation of several applications
• high performance even at low vacuum levels
• outstanding chemical resistance
• long diaphragm life, maintenance-free drive system

Description
Vacuum filtration is one of the most common applications used for sample preparation in chemistry, microbiology, waste water control and other analytical processes. The ME 1C diaphragm pump offers a compact, high performance and easy-to-use solution which is perfect for single filtrations. This development, based on the highly successful technology of the oil-free diaphragm pump MD 1C, provides a well-proven and extraordinarily long diaphragm life time. The functional, space saving and innovative design with easily accessible, top-mounted power switch ensures convenient and quick operation for day-to-day lab work. Robust PTFE diaphragms and valves provide optimal chemical resistance. A manual vacuum regulator valve with dial gauge for adjustment of pumping speed and ultimate vacuum is available as accessory.
Performance features
• convenient, quick and simple to use due to the new top-mounted power switch
• whisper quiet and very low vibration
• requires minimal benchtop space
• maintenance-free drive system and proven long diaphragm life
• high chemical resistance

Laboratory operations involving weighing, mixing and dispensing hazardous or nuisance powders can now be performed safely and economically with the Esco Powdermax 1 Powder Weighing Balance Enclosure. The enclosure’s unique design maintains balance stability to 4 decimal places without compromising containment.
Designed specifically for powder containment applications, the Powdermax Enclosure employs carefully directed inward airflow at the face of the enclosure to protect the operator from exposure to hazardous powders or potent pharmaceutical compounds. The aerodynamically designed enclosure reduces airflow turbulence for maximum containment while minimizing the effect that air drafts may have on sensitive weighing balances. The enclosure design exceeds the containment requirements of ANSI/ASHRAE 110 as proven by independent type testing. All exhaust air is HEPA-filtered, removing virtually all particulate matter, before recirculation to the laboratory.
Features
• Chemical and abrasion resistant removable phenolic worktop
• Isocide™ antimicrobial coated structure eliminates 99.9% of bacterial presence on external surfaces within 24 hours
• A fully configurable Sentinel™ microprocessor control with audible and visual alarms for unsafe conditions
• 2 (two) provisions for electrical wiring at the back to easily connect any apparatus to a power supply from inside the main chamber
• Built-in 5000k warm white fluorescent lighting
• Optional transparent acrylic back-wall, ideal for classrooms and educational demonstrations
• Optional mobile cart for placement of Powdermax™ 1. It has foldable trays to accomodate storage of large equipment.

Ultra-Low Temperature (ULT) Freezers are widely used in scientific research for long-term storage of samples. As ULT freezers are often operated at -80°C continuously for years, reliability is of paramount importance to the researchers.
Constructed from high-quality proven components with energy-efficient refrigeration design, Esco Lexicon® II ULT freezers provide top notch protection that can withstand the test of time to guarantee the integrity of your samples. Superior performance, lower energy costs, better protection.
Features
• Gold Controller
Simple, intuitive operation
Large display of actual temperature with a simultaneous display of set temperature and ambient temperature
USB interface allows transfer of temperature data and the last 20 system events
Advanced input voltage Buck/Boost transformer protects critical freezer components.Additional sample protection!!
• Fast Pull Down
Pull down time is the time required to bring down the temperature of the ULT freezer from ambient to the set temperature.
Esco Lexicon® II has a short pull down time which signifies an efficient refrigeration system
• Fast Temperature Recovery after door opening
Esco Lexicon® II recovers temperature in minutes following a 1 minute door opening.
Fast recovery in temperature ensures integrity of stored samples.
• Excellent Uniformity
Uniformity test measures the difference between the coldest spot and warmest spot in the freezer chamber when the freezer is operating at set temperature.
Esco Lexicon® II has excellent uniformity under normal operating conditions.
This guarantees that all samples are at the correct temperature.
• Extended warm-up Time during a power failure
Warm-up time measures the time taken for temperature to rise up (from -80°C to -50°C) when the power is interrupted
With a robust insulation system in place, Esco Lexicon® II has the best warm-up time among the freezers compared on the right*. Slower warm-up during an extended power failure buys the user time for carrying out a back-up plan.
• Other Features
Sample port
Excellent triple gasket door seals
3 or 5 individual inner doors
Modern refrigeration system
Pressure equalization port
Isocide™ powder coat
Quickopen™ fast door re-open system
