Product Description

The MiniGala y E CO

Incubator is designed to ensure accurate and reliable operation. The unit

incorporates a touch sensitive keypad and two, 3 digit L. E. D. displays which allows easy setting and

onitoring of the cha ber condition.

The icroprocessor control syste ensures a rapid, controlled return to opti u cha ber conditions

after a door opening whilst also preventing any overshoot.

A ther al heating ele ent co pletely surrounds the incubator providing an even te perature within

the cha ber. The independently heated outer door is designed to ensure an even distribution of heat

thereby eli inating condensation on the inner door.

Incorporated into the unit is an over te perature safety syste . This operates independently of the

ain control syste .

A purpose designed hu idity control syste allows a high unifor relative hu idity and prevents

undesirable condensation in other parts of the cha ber. The anual control syste allows li ited

adjust ent over an approxi ate range of 95 – 97% r/h.

A solid state infra red sensor is used to control the level of CO

giving excellent reliability and is

unaffected by hu idity. The CO

syste has a se i-auto atic zero function which provides a si ple

process for the user to follow to aintain the correct CO

level within the cha ber.

There is a two level alar syste . The cha ber onitoring alar is progra able and will alert you

if te perature or CO

have not recovered within a preset ti e after the door has been opened. If not

required, this syste can be disar ed. Syste alar s occur only if a fault has developed which

requires user intervention to rectify.

Air circulation is achieved without the use of a fan eli inating this potential source of conta ination

and reducing s all sa ple evaporation within the cha ber.

The 50 litre cha ber and all internal co ponents are anufactured fro polished stainless steel.

The shelf rack syste is designed for co plete re oval and easy access to the s ooth interior for

quick and thorough cleaning.

The outer shell of the incubator is anufactured fro zinc plated stove ena elled steel to give a

durable corrosion resistant finish.

The outer door and top cover are vacuu for ed fro ABS plastic and they provide a high level of

insulation. The keypad and display are incorporated into the top cover per itting axi u usable

cha ber volu e.

Guidance Notes and Routine Checks

2.1 To ensure that cha ber conditions re ain as stable as possible always ini ize the length

of ti e that the inner door is open. The agnetic door catch is specifically designed to ake door

opening and closing as easy as possible. When opening the inner door, wipe off any s all drops of

condensate that ay have for ed on the inner seal. This will avoid a build up of condensation.

2.2 For cell culture work – we reco end the use of copper sulphate (or recognised biocide) in

the hu idity tray. Tests have shown that as well as inhibiting bacterial growth in the tray this

can reduce conta ination on the cha ber walls (one s all teaspoonful copper sulphate

reco ended).

2.3 For IVF and other sensitive work – we do not reco end the use of any biocide in the

hu idity tray. To reduce the possibility of conta ination, the hu idity tray water should be

changed and the hu idity tray cleaned with 70% Alcohol / 30% distilled water solution every

10 – 14 days. To re ove / replace the hu idity tray: - turn the tray through 45° and re ove

for refilling. To replace the hu idity tray, carefully turn through 45° and pass the tray through

the front of the shelf racks.

2.4

Daily

2.4.1 Check that the te perature and CO

levels are reading within specification.

2.4.2 Check the reserve pressure in the CO

cylinder (nor ally 50 bar when full). The design of

the incubator ensures very low consu ption of CO

and during nor al working conditions a type K

cylinder should last approxi ately 12 onths. If there is a significant drop at the cylinder 50 bar

pressure, it eans that the cylinder is al ost e pty and should be replaced, ensuring that there are

no leaks at any of the joints.

2.5

Monthly

2.5.1 If not changing the hu idity tray water / cleaning hu idity tray regularly - top up the hu idity

tray (to a axi u volu e of 0.5 litres). The use of war water (approx. 37.0°C) will ensure a rapid

return to opti u cha ber conditions. After topping-up, check that the hu idity tray is central

between the racks and pushed back against the stops.

control syste the incubator feet must be fitted. Feet are supplied fitted to the unit.

4 Anti-slip pads for the adjustable feet

1 Black sensor cover (in situ)

If required, further shelves can be purchased up to a axi u of 6. The hu idity tray has a fixed

position at the lowest shelf rack position. The hu idity tray should always be left in place even if the

incubator is not hu idified.

3.3 In order to use the incubator you will require:-

a) A 220/240V 50 Hz or 100/120V 50/60 Hz earthed electrical supply - ini u

capacity 3 a ps (5 a ps High Te perature Deconta ination Models).

A 100/120V 50/60 Hz earthed electrical supply - ini u capacity 6 a ps (8

a ps High Te perature Deconta ination Models).

b) CO

gas cylinder (100% CO

vapour withdrawal) together with a two

stage regulator for pressure control to 0.35 BAR. (5lbf / in

c) Copper Sulphate or other biocide for the hu idity reservoir (optional).

3.4 The incubator is designed to operate at a cha ber te perature of 4.0°C above a bient and

at an absolute ini u a bient te perature of 15°C if being used at 37°C. Therefore care

should be taken to avoid placing the incubator in draughts, direct sunlight or near a radiator.

The operating temperature range indicated above excludes any heat generating

equipment operating within the unit. The presence on any such appliance will affect the

operational temperature characteristics.
