Julabo FP50 Refrigerated/Heating Circulator with MV/K-S Control Unit

This was removed from a university lab where it was surplus to requirements.

It consists of;

Control unit - Model - MV/K-S GB

Chiller Unit - Model FP50 GB

The unit powers up and has been tested with a digital thermometer.

You can set the chiller to -50 but it didn't drop lower than -20 after running all day. Our thermometer read -17. This was likely due to the concentration of antifreeze we used.

It was set to 37 which it reached and held at quickly. We then set it to the max of 100 which it also reached and held at.

It is in reasonably good cosmetic condition with some marks and staining from use.

This Thermo Scientific VersaCool Refrigerated Circulating Water Bath was removed from a university lab where it was surplus to requirements.

The unit powers up and is in very good cosmetic condition. It was tested with a digital thermometer (not included).

Heating:-

Tested with water, the temperature was set to 37˚c, the temperature quickly went up to 38˚c while the thermometer read 37˚c. It was then tested up to the maximum temperature (for water) of 90˚c which it reached after around 10 minutes, thermometer also read 90˚c. It can go higher but we didn't want it to boil. It is rated for 150˚C.

Cooling:-

Tested with Antifreeze, the temperature was set to -20˚c, it dropped quite quickly to -8˚c but seemed to stop cooling from there, only dropping a further 0.3˚c over the next few hours. The thermometer read -9.6˚c. This is likely due to the concentration of antifreeze used.

This Thermo Fisher Scientific NESLAB RTE 7 Circulating Water Bath was removed from a university lab where it was surplus to requirements.

The item is in good cosmetic condition with marks from use.

The item powered on without issue and was tested with a digital thermometer (not included). We tested the chiller with 50/50 antifreeze.

When set to -25˚C the display showed -10.6˚C and the thermometer measured -9.0˚C. This is likely due to not using a high enough concentration of antifreeze.

When set to 4˚C the display showed 4˚C and the thermometer measured 4.0˚C.

When set to 37˚C the display showed 37˚C and the thermometer measured 36.6˚C

When set to 100˚C the display showed 100.5˚C and the thermometer measured 100.3˚C.

The max operating temperature is 150˚C but we were unable to operate it to that temperature.

This Lauda RE210 Refrigerated Water Bath was removed from a university lab where it was surplus to requirements.

The unit powers up and was tested and calibrated with our digital thermometer(not included). It is in full working order but may need calibrating to your thermometers.

It is in good cosmetic condition with minor marks from use.

This Neslab RTE-101 Refrigerated Water Bath Circulator Type - R-134A was removed from a university lab where it was surplus to requirements.

The item powers on and is in a reasonable, used cosmetic condition.

The uni powers up and has been tested with a digital thermometer (not included).

Chilling:-

The temperature was first set to its minimum setting of -30˚c, it dropped as low as -13˚c before it started to climb back up. This is likely due to the concentration of antifreeze used.

Heating:-

The temperature was set to 37˚c and it climbed from -12 to 37˚c within 10 minutes.

The temperature was finally set to it's maximum of 155˚c but when it reached boiling point at 100˚c we switched it off.

This Huber Minichiller Refrigerated Laboratory Water Bath was removed from a university lab where it was surplus to requirements.

The unit powers up and has been tested with a digital thermometer (not included).

When set to -20˚C it dropped to -12˚C after running for 5 hours. It is not designed to heat.

It is in good cosmetic condition with some marks from use.

This Neslab RTE-101 Refrigerated Water Bath Circulator Type - R-134A was removed from a university lab where it was surplus to requirements.

The unit powers up and has been tested with a digital thermometer (not included). It was first set to the minimum temp of -30C. It dropped to -16.8C after about 8 hours of running. It was then set to 37C and our thermometer read 36. It reached the boiling point with no problems.

The unit is in reasonably good cosmetic condition but has some marks from use.

This Grant LT6-40 Recirculating Water Bath was removed from a university lab where it was surplus to requirements

The unit powers up and has been tested with a digital thermometer (not included). It is in good working order between 3 and 100˚C

It is in reasonable cosmetic condition but has marks from use.

This Grant GR150 Recirculating Water Bath Chiller was removed from a university lab where it was surplus to requirements.

The unit powers up and has been tested with a digital thermometer (not included).

Set to -10ºC our thermometer showed -9.6ºC.

Set to 10ºC our thermometer showed 10ºC.

Set to 37ºC our thermometer showed 37ºC.

Set to 100ºC(max) our thermometer showed 101.3ºC.

We filled it with antifreeze and tested the minimum temperature. It was set to -20ºC but it wouldn't drop past -10ºC. We think the antifreeze froze inside the re-circulator pipe.

All of these temperatures were reached quickly without any issues.

It's in reasonably good cosmetic condition but has some scale build up.

We stripped down the cooling fan and greased both ends of the shaft then rebuilt it. It runs silently.
