Heat-On Instructions
Fluoropolymer Coated
The Heat-On blocks, holders and inserts can be purchased as polymer coated. The block’s finish does not affect the
temperature or stirring performance of the product, however the coatings do vary in regard to chemical resistance.
Fluoropolymer Coated Blocks
The fluoropolymer coated Heat-On blocks offer superior resistant to the majority of solvents, acids and alkalis.
M
ulti-well formats for smaller flasks
The unique Multi-Well Holder is designed to hold either one or two inserts for flasks or tubes.
The inserts are available for 10ml, 25ml, 50ml, 100ml or 150ml flasks as well as multi-tube
inserts for 16mm ø, 20mm ø and 24mm ø tubes or vials. Flask inserts feature cut-away sides
to enable the use of flask with or without sidearms.
Simply place the multi-well block holder directly on to the hotplate or adapter plate
(
see page 5) and select appropriate insert for your flask(s) or tube(s).
Warning
Always refer to the manufacturers operating instructions for your stirring
hotplate before using it with Heat-On, to be sure of any limitations or safety
restrictions.
Important Notes
1: Compatibility between Heat-On block and flask is essential for overall safety
of this equipment (see page 10).
2: The Multi-Well Holder only accepts ONE 150ml inserts.
Important Note
It is important to clean off any residual chemical spills immediately after they occur.
Important Note
Heat-On blocks can be used up to 200˚C without damage to the block. Temperatures up to 260˚C can be achieved but
some minor surface degradation may occur.
Important Note
Extended exposure to acids or alkalis will attack the surface of the Heat-On blocks. The stronger the concentration and the
longer the exposure time the more chance and intensity of any attack. Heat will also speed up and intensify any attack.
e.g. hot concentrated sulphuric acid will damage the fluoropolymer coated Heat-On blocks over a period of time.
