Laboratories using a deioniser system to generate deionised (or DI) water in house should test the water produced regularly, to ensure the system is working well and producing water of the required purity.
Conductivity is usually used as a good indicator of the quality, as the test is simple to perform.
However is is important to choose an instrument which is able to read the very low values found in DI water, as not all meters will work in this environment.

Q: How should I clean my Hach PourThru (pour through) cell?
Pour Thru cells are used in some Hach tests for fast testing without the need for individual glass sample cells. The solution to be analysed is delivered to the cell by a funnel and tubing setup, and then flows out of the cell after measurement to a drain tube.
Due to the small parts, the pour thru cells can develop a buildup of solids inside, especially if samples are left sitting in the cell after measurements.
It’s important to clean them thoroughly to ensure your results remain accurate.
Follow these simple steps to keep your pour thru cell in good condition…

After glassware has been washed, it should be dried carefully to avoid introducing any impurities. Drying with paper towels can introduce fibres or dust which could affect high accuracy work.
There are 3 main methods for quickly and cleanly drying lab glassware, each with their own specific benefits and drawbacks.

Hundreds if not thousands of glassware pieces have to be washed every week in a lab. The last thing you want is not to be able to peel off their labels and be left with a tacky mess. The Stick-off Labels from camlab easily slide off glassware after just a short glasswasher cycle or after a soak in water. See our video below putting them to the test!
For more information on the range of labels available from camlab in the UK or the rest of the world please get in contact with us here or fill in the form below.

Answer: a Brinometer!
Brine is simply defined as a solution of salt in water. It has a wide variety of uses from the transport of thermal energy, de-icing the roads or in cooking to preserve meat or vegetables.
The low levels of salinity commonly found in food or seawater can be tested in a number of ways such as on the Laqua Twin sodium meter , Laqua Twin salt meter or for a multi-parameter unit, the PoolPro by Myron. Brine however tends to reach much higher salinity levels ranging up to ~26% salt, too high for standard salt meters. Read the rest of this post »

We’ve discussed the benefits of ducted or ductless fume hoods in previous blogs. The concept of ductless filtering is now well established and many users are realising the enormous benefits and cost savings associated with this approach.
Erlab, one of the leading manufacturers of ductless filtering systems has taken this concept a step further by introducing a new SMART range of both ductless fume hoods and chemical storage cabinets. They are safer to operate, combining activated carbon and HEPA/ULPA filters to adapt to the chemical manipulations required.
The new SMART series has real time sensors to detect main filter saturation with solvents, formaldehyde or organic vapours. Erlab have also included a secondary safety filter in case of main filter saturation.
Gone is the manual air flow sensor, replaced by the air face velocity sensor built into the cabinet and an alarm should the fan fail at any time.
The biggest benefits to emerge are the cost savings.. With no external ducting required and the savings this brings, the new SMART fume cabinets cost less than 100 euros to run per year, and even taking the cost of the replacement filter into account there are massive savings over conventional ducted systems. There is no chemical release into the atmosphere, and the cabinet has low energy consumption making it the ideal choice for academia and institutions where lowering their carbon footprint is becoming mandatory.
The new Smart Fume hoods have light guided communication which is constantly visible around the filter housing. When the light is constant the hood is operating safely. To alert you the light will start to gently pulse or flash. A simple light pattern will indicate if:
- Air flow is compromised
- The fan has failed
- Filter breakthrough as occurred and the filter needs changing
- The Draft shield was left open for a prolonged time
The eguard App gives you remote control to monitor the fume hood, change the settings and deliver safety alerts immediately to your mobile, tablet or PC.
The SMART fume hoods have added detection systems with three types of ‘molecode’ detectors which monitor the filter saturation and activate the visual detector when the filter needs changing.
- Molecode S for solvents
- Molecode A for acids
- Molecode F for Formaldehyde
The same technology applies to the Smart range of Ductless fume hoods and Storage Cabinets. For more information and to find out which hood is right for your own laboratory contact us to arrange a free consultation.
