3.FEATURESOFTHETURRET6
A.GENERALDESCRIPTION
TheTurret 6hasarotating,temperature‐controlled,cuvettetowerwhichholdsuptosixcuvettes.
Thecenterofthetowerishollow,permittinglighttopassintotheentrancehole,throughthetower,
throughacuvetteandexittheoppositesidefromtheentrance.Aplasticcoverenclosesthecuvette
tower,providingthermalinsulation.Afloorisattachedtothebottomofthecuvettetower,andthe
rotatingbodyoftheholdercontainsaPeltierelementsandwichedbetweenthisfloorandabrass
heatexchanger.Waterisputthroughtheheatexchangertodrawoffheatgeneratedwhenthe
temperateislowered.

Accessfortheseutilitiesmayneedtobelighttight.

CAUTION: Accidentlyattachingawaterlinetothedrygasbarbwillseverelydamagethe
instrument!Attachthelineswithcare.
B.CUVETTEHOLDER

TheTurret 6holdsstandard10x10mmcuvetteswithoutsidedimensionsof12.5x12.5mm.A
metalclipisusedtopusheachcuvetteintooneofthecornersofitsindividualspaceforreproducible
positioningandtofavortemperaturetransfer.WallsoftheTurretbodyarerelievedtoprevent
scratchingoftheopticalsurfacesofthecuvette.

Cuvettesshouldbe45mmortaller,otherwisetheywillbedifficulttorecoverfromthecuvette
holders.
C.CUVETTEZ‐HEIGHT
The“zheight”ofacuvetteisthedistancebetweenthebottomsurfaceofthecuvetteandthe
designedpositionfortheopticalcenterline,wheretheincidentbeamoflightstrikesthecuvette.

E.COOLINGWATERFORTHEPELTIER
ThePeltierelement(or“thermoelectriccooler”)isaheatpump.Whencooling,ittransfersheat
fromtheTurretbodytoaheatexchanger;whenheating,electricalpolarityisreversedandit
transfersheatfromtheheatexchangertothetower.Whencooling,itisparticularlyimportantto
transferthisheatawayfromthePeltier.Thisisaccomplishedwithflowingwaterthroughtheheat
exchanger.

Asourceofwater(orothercoolingfluid)mustbeconnectedtothe⅛‐inchhosebarbsonthebackof
theTurret 6.IfyoupurchasetheBATH10fromus,youwillgetaninexpensivesubmersible
aquariumpump,theappropriatefittingsforconnectingtubing,andaplasticbucket.Connectthe
pumptotheTurret 6,placeitinthebucketwithwater,andrunareturntubetothebucket.Amore
robustpumpisavailableastheBATH100forahigherprice,althoughthelargerpumphasahigher
Wattageandtendstoheatthewaterwhenusedforextendedperiodsoftime.

Youmayalsoprovidethecoolingwaterfromanothersource,suchasarefrigeratedcoolingbathor
evenatapforbriefuse.

Youwillneedaflowof100‐300ml/minute.Thisflowshouldrequireapressureofabout3‐5psi
(0.2‐0.3bar).Donotexceedaninputwaterpressureof25psi(1.7bar),asdamagemayoccurinside
theTurret 6.Theheatexchangerandhosebarbsarebrass,andthetubinginsidetheTurret 6is
vinyl.Besurethatanycirculatingfluidused,otherthanwater,willnotcorrodethesematerials.

ThetemperatureoftheheatexchangerintheTurret 6ismonitoredusingathermistor.Ifthe
temperatureexceeds60°C,thentemperaturecontrolisshutdowntopreventdamagetothePeltier
elementandthewarning,“checkcoolantflow,”displayedontheTC1temperaturecontroller.This
willhappenifthecirculatingfluidgetstoowarmand/orisrestrictedinflow.Theheatexchanger
temperaturemaybeaccessedbycomputerthroughtheRS232orUSBconnectionsonthebackof
theTC1TemperatureController(seeExternalcomputercontrolbelow).

Temperatureincreaseswillbefasterwhenroomtemperaturewaterisusedinthecirculator.
Temperaturedecreaseswillbefasterwhenicewaterisused.Onlywatershouldbecirculatedusing
theBATH10.Whenusingarefrigeratedbath,circulatingpre‐cooledfluids(suchas30%methanolor
dilutedethyleneglycol)atbelow0°Cwillpermitmeasurementsbelowthespecifiedtemperature
range.


F.DRYGASTOMINIMIZECONDENSATION
DrygasflowsintotheTurret 6viathestainless1/8‐inchhosebarbontherearside.Thegaspasses
throughsmallchannelsinthebaseoftheTurretbody,topartiallyequilibrateintemperature,before
passingupthroughsmallholesonboththeinsideandoutsidecuvettesurfaces.Aflowofdrygasto
preventcondensationisnecessaryanytimetheTurret 6iscontrolledbelowthedewpoint
temperaturepresentontheinsideofthesamplecompartmentofthespectrometer.Forambientair,
thiswouldtypicallybeabout5°C.
G.EXTERNALTEMPERATUREPROBE
A¼‐inchphonejacklabeled“Probe”canbefoundonthebackpanelofTC1TemperatureController.
ThisjackwillaccepttheplugonastandardSeries400orSeries500thermistorprobe.Whenaprobe
ispluggedintothejack,theprobetemperatureispresentedonthedisplayoftheTC1.Placethe
probeinasampletomeasuretheactualtemperatureofthesample,whichwilllagintimefromthe
temperatureofthecuvettetower.

Wedonotselltheprobe,buttherearemanySeries400and500probesonthemarket.Quantum
Northwest’spreferredprobeistheYSI423availablefromColeParmer.TheYSI423isreasonably
resistanttoimmersionandrespondsrapidlytotemperaturechanges.Also,thefine,coiledwiresof
theYSI423conductverylittleambientheattothethermistorattheend.

ExcellentSeries500probescanbeobtainedwithdiameterslessthanamm,providingaccesstosmall
volumes.Adisadvantageoftheseprobesisthattheyarenotpre‐calibrated.
H.EXTERNALCOMPUTERCONTROL
AllfunctionsmaybeaccessedeitherthroughaSerial(RS232)oraUSBlocatedonthebackofTC1
TemperatureController.YoumaywriteyourownprogramorpurchaseourapplicationprogramT‐
App.T‐Appwillplottemperaturesoftheprobe,cuvettetoweroreventhePeltierelementheat
exchangervstime.Itwillalsopermityoutosetuptemperatureramps.Ifyouwishtodoyourown
programming,pleaseseetheAppendixforcommunicationinstructionsandthesetoftext


Thisdocumentprovidestheserialcommunicationsprotocolsforversion1.0ofthefirmwareonthe
TC1familyofcontrollers:
TC1/t2–forthet2,singletemperaturecontroller
TC1/t2x2–forthet2x2,dualtemperaturecontrollerforsampleandreference
TC1/Turret6–fortheTurret6,6‐positionturret
TheversionnumberandtheID(seebelow)areshownbrieflyonthedisplaywhenthetemperature
controlleristurnedon.

Allfunctionsofthetemperaturecontrollercanbemanagedfromacomputer,usingthecommand
setdescribedbelow.Ifyoupurchasedyourunitasacomponentofaspectrometerfromcertain
manufacturers,thisfeaturemaybeimplementedthroughtraditionalRS232serialconnectorsonthe
computerorthespectrometerandonthecontroller.Inthiscasetheywillbeconnectedbya
standard15‐pinserialextensioncable(maleconnectorononeendandfemaleontheother).No
driverinstallationshouldbeneeded.

OtherwisetheseriallinkagewillbeestablishedthroughaUSBconnectionbetweenthecomputerand
thecontroller.InthiscasethecontrollerincludeselectronicswhichconverttheUSBconnectiontoa
serialcommunicationsport.However,fortheporttobeavailabletoprogramsonthecomputerit
willbenecessarytoloaddriversoftware.Itisimportantthatthedriversoftwarebeloadedbefore
connectingaUSBcablebetweenthecontrollerandthecomputer.ContactQuantumNorthwestfor
furtherinformation.


ToRampthetemperature:
1.equilibrateatthestartingtemperature,

18

2.settheramprate,
3.setanewtargettemperature(commandclass5).
Thetargettemperaturemaybeaboveorbelowthecurrenttemperature;assoonasitisset,the
rampwillbegin,upordown,tothatnewtarget.

andtargettemperaturecanbesettostartanewramp.
Onceyouaredone,settheramprateto0.Otherwise,settinganewtargettemperaturelaterwill
initiatearamptothattargettemperature.

Notes:
Theminimumsettableramprateis0.01°C/minute.
Forhigherrampsettings,theobservedratemaybelowerthanthatcalculatedfromRTandRSor
itmaybenonlinearoverpartofthetemperaturerangebecausethemaximumpossiblerateof
heatingorcoolingislimited(anddependentontherampdirectionaswellasonthe
temperature).
Whentherampingprocessiscompletedthecontrollerwillsendaresponseoftheform[F1TT#]
asanotificationoftheendoftheramp.Thisresponsecanbeblockedatanytimebypreviously
