Electrical installation

THIS EQUIPMENT MUST BE EARTHED

Before connection please ensure that the line
supply corresponds to that stated on the rating
label. Power consumption is 50W.

There is an IEC socket at the rear on the left
hand side of the instrument for connection to
the mains supply, (see figure 1). The unit is
supplied with two mains leads fitted with IEC
plugs for connection to the instrument. One has
a U.K. 3 pin plug and the other has a 2 pin
“Shuko” plug for connection to the mains
supply. Choose the lead appropriate for your
electrical installation and discard the other.

Should neither lead be suitable you should
obtain a moulded lead locally. If this is not
possible, take the lead with the U.K. plug and
replace the plug with a suitable alternative. See
the enclosed instruction sheet for advice on how
to carry out this procedure.

Should the mains lead require replacement a
cable of 1mm

2

of harmonized code H05V V-F

connected to an IEC 320 plug should be used.

N.B. The UK mains lead is protected by a 10A
fuse mounted in the plug top.

The mains lead should be connected to the
instrument BEFORE connection to the mains
supply.

IF IN DOUBT CONSULT A QUALIFIED
ELECTRICIAN

General description

The sample for the melting point test is placed in
a capillary tube and inserted in to the aluminium
block inside the heater. Using the manually
adjustable heating rate, the SMP11 will rapidly
heat samples up to 20°C per minute to the melt
temperature and up to the maximum
temperature of 250°C. An accurate reading to
within 1°C of the melt temperature can be
achieved by using a slower heating rate of
between 1 and 10°C per minute. The sample is
observed through the magnifying lens until the
melt occurs and the melt temperature read from
the thermometer.

Before use

1. The SMP11 is supplied in custom-made
packaging; it is recommended that the
instrument should be kept in this packaging
between uses to maintain it in optimum
condition.

2. (First time only) Once the unit is unpacked,
select the appropriate choice of self adhesive
instruction label from the multi-language set
provided. Peel off the backing and stick the
label onto the large recessed metal area on
the right side of the SMP11 (see Fig 2).
Apply the label carefully using a flat object to
smooth away air bubbles.

3. Place the unit on a firm, level surface.

4. Insert the bulb of the non-toxic spirit filled
thermometer into the side of the heating
block (see Fig 3), while resting the other end
in the slot on the right hand side.

Measuring a melting point

N.B. If the unit has been used recently the block
may be too hot for your sample. If this is the case
turn the apparatus off and allow the unit to cool
before proceeding. An optional brass cold finger
(ref. SMP1/2) can be inserted into the
thermometer hole; this has the effect of drawing
heat out of the heating block and so considerably
reduces the cooling time.

1. The SMP11 is supplied with a pack of 1.9mm
open-ended capillary tubes. It is recommended
that one end of the tubes should be sealed
with a Bunsen burner flame, by a fully trained
person, prior to use. Alternatively a pack of
capillary tubes that have been sealed on one
end can be purchased from your Stuart
stockist (ref. SMP10/1).

2. Place a small amount of your powdered
sample into the end of a 1.9mm diameter
glass capillary tube.

3. Insert the capillary tube into the side of the
heating block via the holes provided (see Fig

4). A maximum of 3 capillary tubes can be
inserted at any one time.

4. Look down the lens and position the tube so
that the sample can be observed clearly
(see Fig 5).

5. It is assumed that the approximate melting
point range is known, if not a rough run may
be required to gauge the approximate range.

6. In order to achieve a fast and accurate
melting point range it is important to use a
rapid heating rate as the sample heats up
from ambient and a much reduced heating
rate as the sample approaches melt, see Fig
6 for an ideal heating curve for a sample
with a melting point of 240°C.

7. Connect to the mains electricity supply.

8. Start by heating the sample at the maximum
rate by setting the heating controller to max.

Caution: The heating block may be HOT.

9. Once the thermometer reaches 60% of the
expected melting point the heating controller
should be reduced to 10°C/min, by turning
the heating controller anti-clockwise.

10. Continue to reduce the heating controller so
that it is on 1°C/min when the sample is
within 15°C of the expected melt.

11. Observe the melt through the eyepiece,
while recording the temperature on the
thermometer; make a note of the melt
temperature.

12. Turn off to begin cooling, or insert the
accessory brass insert to speed up cooling.

Cleaning & Servicing

WARNING: Ensure the unit is
disconnected from the mains electricity
supply and allowed to cool before
attempting any cleaning or servicing.

Cleaning

Periodically clean the instrument using a damp
cloth and mild detergent solution. Do not use
harsh or abrasive cleaning agents.

In the event of any breakage of the thermometer
bulb or capillary tubes disconnect the unit from
the mains supply. Any debris can be removed
simply by unscrewing the dome nuts holding the

3

lens and then lifting the lens out (see Fig 7). The
instrument can then be turned upside down so
that any debris falls out. Once the lens has been
removed the chamber can be cleaned with a
damp cloth or a soft brush.

Servicing

This unit does NOT require routine servicing.

Repairs

There are no user replacement parts on this
instrument. If this unit were to stop working or
malfunction in any way, only suitably qualified
personnel should investigate the problem. Prior
to any internal repairs being undertaken a
service manual should be requested from the
Technical Service Department of Barloworld
Scientific Ltd. quoting both the model and serial
number of your product.

NB: Fuses are mounted in both the live and
neutral line.

Only spare parts supplied or specified by
Barloworld Scientific Ltd. or its agents should be
used. Fitting of non-approved parts may affect
the performance and safety features designed
into the instrument.

If in any doubt, please contact the Technical
Dept. of Barloworld Scientific or the point of
sale.

Installation électrique

CET APPAREIL DOIT ETRE RELIE A LA
TERRE.

Avant de connecter l’appareil, vérifier que
l’alimentation délivrée par le secteur correspond
à celle précisée sur l’étiquette d’identification. La
consommation électrique est de 50 W.

L’appareil possède une prise IEC à l’arrière du
côté gauche pour le raccordement au secteur
(voir figure 1). L’appareil est alimenté par deux
cordons d’alimentation équipés de fiches IEC
pour la connexion de l’appareil. Un des cordons
possède une fiche U.K. à 3 broches et l’autre
une fiche à 2 broches “Shuko” pour le
raccordement au secteur. Choisir le cordon
correspondant à son alimentation électrique et
mettre l’autre de côté.

Si aucun câble ne correspond, se procurer
localement un cordon moulé. Si cela est
impossible, prendre le cordon avec la fiche U.K.
et remplacer la fiche par un dispositif approprié.
Se reporter à la fiche d’instructions jointe pour
des conseils sur la procédure à suivre.

Si le cordon d’alimentation doit être remplacé,
utiliser un câble de 1mm

H05V V-F connecté à une fiche IEC 320.
N.B. Le cordon d’alimentation UK est protégé

par un fusible de 10 A installé sur le dessus de la
fiche.

Connecter le cordon d’alimentation sur l’appareil
AVANT de le raccorder au secteur.

EN CAS DE DOUTE, CONSULTER UN
ELECTRICIEN QUALIFIE.

Description générale

L'échantillon pour le test portant sur le point de
fusion est placé dans un tube capillaire et inséré
dans le bloc en aluminium à l'intérieur du
réchauffeur. A l'aide de la commande manuelle
de réglage de chauffage, le SMP11 chauffe
rapidement les échantillons jusqu'à 20°C par
minute, pour atteindre une température
maximale de 250°C. Une lecture précise à une
marge d'1°C de la température de fusion peut
être obtenue en utilisant une vitesse de
chauffage inférieure comprise entre 1 et 10°C
par minute. L'échantillon est observé à travers
d'une part une loupe grossissante jusqu'à ce que
la fusion se produise, et d'autre part la lecture de
la température de fusion à partir du
thermomètre.
