BackgroundResearch Instruments have been working in the IVF field for 25 years and are experts in the supply and support of the needs of UK Embryology Laboratories

Our suppliers have a wealth of experience in the field of gas generation and lab supply and have an award-winning NitroGenerator that produces Nitrogen gas to pharmaceutical grade quality

The two companies have joined partnership to introduce and support Nitrogen gas generation into the IVF market to help reduce the higher costs associated with standard gas bottles.

Nitro Generator NG1 – NG5• The award-winning Nitro Generator is a

flexible and expandable state-of-the-art Nitrogen Generator that produces flows from 1 to 10 l/min at very high purity.

• Discrete, efficient, modularsystem that produces high purity nitrogen only when you need it– all you need is compressed air.

• The NitroGenerator uses PSAtechnology for superior performance and reliability. A range of models is available to cover most applications.

Process Description• NitroGenerator has a built-in standby system,

which ensures the most efficient use of electricity and the systems internal components.

• Compressed air enters the generator via a 0.01-micron filter [1] that removes contaminants and bulk moisture via an integrated auto drain. When the control system assesses that more nitrogen is required, solenoid valve [2] is opened and the pressure is allowed to build in the column [4] containing Carbon Molecular Sieve (CMS) and a residue moisture catcher [3].

• This sieve adsorbs the oxygen and leaves the dry nitrogen free to flow into the reservoir [7]. After this point, the Nitrogen is allowed to flow to the application viapressure and flow regulators [8].

How does it Work ?

• When selecting a system, consideration should be given to the required flow rate,purity and delivery pressure.

• The larger units are fitted with castors to allow them to be manoeuvred easily into position below a bench top.

• All of the units in the range are built on amodular design to allow the capacity to be expanded upon.

UK Case Study

G.C.R.M. Scotland Pilot Centre

- GCRM Culture in low Oxygen in small (G185 – K systems) bench top incubators and Panasonic 5M (48L)

- Various other small demand units (gas jars)- Nitrogen gas bill from BOC 2010 / 09 was £20 – £25K- Introduced the NG1 from RI and partners and reduced gas bill

dramatically saving on average 20k per annum on gas supply to the lab

Installation & ServicingOnce the correct generator and reserve is selected the Installation usually requires a connection to the change over unit already in place.

Essentially you are swapping over one bottle for one generator so that you still have bottle for switch over / back up in line with your current risk assessment

Two generators on one switch over unit are also possible

Annual servicing is carried out by the experienced partners of Research Instruments who have completed IVF specific training.
