Precision Weighing Cabinets
W-2
Precision and Security in the Investigation
Cruma presents its new cabinet for ultra-precision weighing with total protection for the worker and the environment during the handling of substances developed in research laboratories.
Working with extremely toxic substances is no longer a problem for the laboratory personnel thanks to the filtering system* of highest safety as well as the filter change of our new Cruma W-2 Ventilated Balance Enclosure (VBE).
Sensitive microbalances require a protected and vibration-free environment against air currents. Cruma W-2 guarantees a precise and safe work environment when dealing with highly- active substances, while providing excellent ergonomics and comfort. The work surface is isolated from any vibration thanks to its anti-vibration system* that allows calibrating with accuracy and speed any balance of up to 6 digits**. Its ergonomic design and functionality meet the most stringent quality and safety standards.
*Pat. pending **certified by EA accredited entity
Certified and Patented
Manufactured in Barcelona with European CE components, certified by an external laboratory following international regulations, and applying ISO 9001: 2015 Quality criteria and in the process of patenting its exclusive filtration system.
Extremely Safe
Filtration system with double filtration as standard: HEPA H-14 main filter with BagIn & BagOut system for total operator protection when changing the saturated filter, and HEPA H-14 safety filter at the exhaust.
Economic Savings and Easy to Set-Up
You do not need complicated installation operations to start working with: the customer receives the Ventilated Balanace Enclosure (VBE), unpacks it and just by plugging it in, he can start working, and no need to interrupt a laboratory working at full capacity.
Energy Savings
Unlike traditional extraction hoods, our fume hoods do not use the air conditioning equipment inside the laboratory, which substantially reduces energy costs. The aspirated air is not expelled outside but recirculated back into the laboratory free from contaminating substances.
Advantages
▼ Aileron-shaped armrest for total comfortable operation .
▼ 2 internal electrical sockets that allow clean connections for the different devices used during weighing operations.
▼ Granite work surface positioned on 6 silent blocks that dampens and completely isolates from vibrations when using very sensitive microbalances of up to 0.000001* grams. *certified by EA accredited entity
▼ LED lighting that offers a light intensity greater than 900 Lux.
▼ Waste disposal system integrated in the acrilic side pannel to store and dispose easily and safely of waste
▼ Optional ionization electrode to avoid electrostatic charges in the working area
Possible Applications
▼ Density Measurement
▼ Sample preparation
▼ Emissions test: gravimetric determination of suspended particles
▼ Non-Volatile Residue Test – Gravimetric Determination of NVR Content
▼ Dosing
▼ Moisture Content Determination
▼ Precise Residue Testing – Accurate Standard Preparation
▼ Formulation Development and Production of precise formulations
▼ CHNSO Elemental Analysis – Sample Preparation
▼ Trace Metal Analysis: Sample and Standard Preparation
Ergonomics and comfort for laboratory uses
The multiple warnings and alarms of the integrated control panel allow the user to work in total safety and fully concentrated on his work; at the same time, the wing-shaped profile of the front edge of the table performs two functions: it diffuses the air in a perfectly uniform way and allows the arms to be supported with total comfort.
The aspiration of toxic substances is carried out through suction openings made with a special design and located on the rear panel, which prevent dangerous substances from leaving the device and endangering the user. In addition, its flat and homogeneous shape meets the most stringent requirements in terms of hygiene, decontamination and cleaning.
The large digital screen offers 2 levels of user that make the configuration of the cabinet very practical and safe. Likewise it is provided with a waste disposal system integrated directly into the work surface, which allows waste materials to be disposed very safely.
The BagIn & BagOut system for the change of the clogged filter ensures total safety and protection during the filter change operation, avoiding any possible accident or contamination of the technical personnel.
Cruma W-2 is the ideal Ventilated Balance Enclosure (VBE) for your ultra-precision weighing operations: Safe, ergonomic and comfortable.
Filtration system with double filtration as standard: HEPA H-14 main filter with flow equalizer and HEPA H-14 ejection safety filter, both with an efficiency greater than 99.995% on 0.3 micron particles (MIL-F51068C Standard, EN-ISO 14644-1 and BS 3298).
The main Hepa filter is equipped with a BagIn & BagOut system for changing when the filter has been clogged (detected by the pressure gauge), ensuring total safety and protection during the filter replacement operation, avoiding any accident at all times or contamination of technical personnel.
