Accessory options for OLS200
Lid
Note: Recommended above 60ºC and below room temperature.
LS200 sloping lid - directs condensation to the edges of the bath to prevent it dripping into open flasks
Coolers
Note: Accessory cooling is required for operation around or below room temperature
CW200 heat exchange coil - fits underneath the shaking tray and is designed to be attached to a supply of cooling tap water or a refrigerated circulator. Can be used down to 2ºC above the temperature of the coolant.
CSG200 refrigerated cooler - the coil fits underneath the shaking tray. Cooling rate will depend on the ambient temperature, the supply voltage and the volume of liquid used.
Trays and racks
UT200 universal flask tray - designed for ultimate versatility as to the types and sizes of vessel which can be accommodated. Adjustable spring configuration for maximum flask capacity. The universal tray can accommodate a combination of different flasks, or single size Erlenmeyer flasks as follows:
43 x 25ml
26 x 50ml
15 x 100ml
11 x 250ml
6 x 500ml
3 x 1L
TT200 test tube tray - holds five H1 test tube racks
H1-* test tube racks - choice of 7 variants to accommodate different tube diameters and microtubes:
H1-10 48 x 10mm tubes
H1-13 44 x 13mm tubes
H1-16 24 x 16mm tubes
H1-19 21 x 19mm tubes
H1-25 12 x 25mm tubes
H1-30 10 x 30mm tubes
H1-LE 48 x 1.5 microtubes
UTP plain tray - will accommodate containers, bags and miscellaneous vessels
SBT28 perforated tray - replaces the trolley, providing a platform on which vessels or racks can be placed, for use as an unstirred thermostatic bath
Shaking Water Baths OLS200
What do I use to clean my water bath?
Algal growth can be removed by cleaning with warm soapy water. Rinse thoroughly before re-filling the bath. External surfaces can be wiped clean using a damp cloth and if necessary a mild detergent.

How do I remove limescale?
Limescale build-up can be removed by using a domestic de-scaler

Can I use a bactericide?
We make no recommendations about the suitability of commercial bactericides. Their chemical components and properties vary and may cause corrosion, which would not be covered by our warranty.

Do I need a lid on my water bath?
We recommend the use of a lid if the water bath is used regularly above 60˚C to prevent excessive evaporation and as a safety measure. Polypropylene spheres (our ref PS20) may be used as an alternative.

What water should I use in my water bath?
For long-term reliability of water baths, it is important to use oxygenated water that is free from ions and minerals that can cause corrosion of stainless steel. We recommend the use of distilled water or deionised water from ion exchange systems that do not use salt back flushing to regenerate the ion exchange cartridges. Details on the corrosion process are available on request.

How much water do the GLS400/OLS200 shaking baths hold?
Initially about 9 litres of water should be added to the bath. The final water level is then adjusted to suit the vessels placed in the tray. The max recommended immersion depth of a vessel is 90mm.
[back to the top]
Why is water splashing out of the bath?
There is too much water in the bath. A compromise must be made between the shaking speed, the stroke length and the water level in the bath. Reduce the shaking speed, adjust the stroke length or remove some water.

How do I select orbital shaking in my OLS200?
The OLS200 provides an orbital or linear mode of shaking which is determined by the orientation of the tray. Remove the tray, rotate through 180degrees and replace to select the alternative shaking action.

What is the maximum load?
The max recommended load is approx 3kg which is the equivalent of 3x full 1 litre flasks.
[back to the top]
I have a mixture of vessel sizes. What tray do I need?
The universal tray has a series of springs forming a configurable matrix which will simultaneously hold a mixture of vessel sizes, flasks, beakers, firmly in position.
[back to the top]
Why is the shaking motion jerky and uneven?
The shaking trolley uses magnetically coupling which is driven by a drive magnet inside the unit. As the speed is increased a point will be reached when the magnetic coupling de-latches causing the tray to move erratically or stop. Reduce the shaking speed until the shaking is even. The speed at which de-coupling occurs will vary with load, shaking speed & stroke length.

My OLS200 is not working and the alarm lamp is on
The set temperature is higher than the over-temperature cut-out which has operated. Check that there is water in the bath. Press the reset button. If the reset does not operate turn the over-temperature adjustment screw clockwise. Press the reset button. The over-temperature lamp will go off. Heating and shaking will restart.

Do you have a see-though lid available for the GLS/OLS baths?
The AQL26 clear blue polycarbonate lid is suitable for the GLS/OLS.
[back to the top]
Can I use the OLS200 below room temperature?
It is necessary to use accessory cooling to achieve temperatures below ambient +5˚C. The CS200G immersion cooler will provide cooling as low as zero. The CW200 which is a heat exchange coil is from a cold water source. The min temperature using the CW200 is 2 degrees above the water supply temperature.
