With the help of high-quality Ohaus Frontier rotors and adapters, you can find the best solution for both basic and high-performance sample preparation needs.

These powerful rotary vane pumps feature a particularly compact design and low weight for pumps of this capacity. They are the ideal solution for a wide range of laboratory and process applications that require low ultimate vacuum at medium to increased gas flow rate. Various packages including pump, oil mist filter, etc. are available.

Performance features

• high flow rates even at vacuum levels approaching ultimate vacuum
• high water vapor tolerance due to efficient gas ballast; very good ultimate vacuum even with gas ballast
• vacuum-tight at switch-off; external anti-suckback valve not needed
• large oil volume: Long intervals between oil changes
• ease of maintenance due to telescopic design

PURA water baths stand for innovative, simple, and safe working in the laboratory. All models (except PURA 4) come with an integrated drain screw for quick and clean draining of the baths. PURA water baths are flexible and can be easily transported through ergonomic side recessed grips. Non-slip rubber feet ensure a firm footing and more safety in the laboratory.

Your advantages

• Easy operation
• Bright display
• Mains switch is protected against spray water
• Integrated protection against running dry
• Integrated drain screw (except PURA 4)
• No distracting elements in the bath
• Platform included as standard
• Integrated timer
• Non-slip rubber feet
• Ergonomic recessed grips

Product features:
• Measurement range: 0.1 – 50 μS/cm
• Dimensions mm (W x D x H): 93 x 125 x 96
• Connection: R ¾“

With plastic supports, nozzle diameter 6 mm, length 130 mm, 1 item.
• Area of application: reprocessing laboratory glassware
• Suitable for mobile injector units & baskets screw connection
• Ideal for load items with neck diameters of between 12 mm and 85 mm
• Diameter of cap at top: 11 mm
• Part of the EasyLoad system. The EasyLoad system makes reprocessing laboratory glassware considerably faster, simpler and more reliable. The biggest benefit afforded by the new system is that load items can be positioned over nozzles both more simply and faster as height adjustment of the holders is no longer necessary thanks to the smart combination of nozzles and holding frames. This makes correct positioning extremely easy.
