1. INTRODUCTION.
The Macro-Kjeldahl Equipment.
The Bibby Scientific MQ Series of products has been designed for Kjeldahl
extraction on a macro scale.
These multibank units are available with either 2 or 6 recesses. The units have a
stainless steel housing. There are two capacity sizes available, one for 100300ml vessels and the second for 500-800ml vessels.
The lower part of the unit houses the control equipment. This is separated from
the heating element by a stainless steel tray and a well ventilated air space.
Each heating mantle has its own energy regulator incorporating an ON/OFF
switch and an amber, mains to heater neon indicator. There is also a mains On
indicator (clear) on the front panel. The units are also fused on the supply line
and neutral except MQ3868B/Ex1 which has no fuse ( see Section 5).
Note: MQ products incorporate earth screen and are CE marked.
The six recessed versions when specified for use with 500-800ml vessels is only
available in a 230 V~AC rating. All other MQ’s are available in 115Volt~AC or
230V~AC. Note the MQ3868B/Ex1 is only for sale outside of Europe and is not
CE approved.

accordance with current area legislation.
3.2. General Safe Operating Practice.
Always follow good laboratory practice when using this
equipment. Give due recognition to your company’s safety and
legislative health & safety procedures and all associated legislation
applicable to your areas of operation. Check laboratory procedures for
substances being heated and ensure all hazards (e.g. explosion,
implosion or the release of toxic or flammable gases) that might arise
have been suitably addressed before proceeding. When heating
certain substances the liberation of hazardous gases may require the
use of a fume cupboard or other means of extraction.
Ensure equipment is used on a clean, dry, non-combustible, solid work
surface with at least 300mm suitable clearance all around from other
equipment.
position the product so that it is difficult to disconnect from the
mains supply.
touch the heating element or any glass vessel whilst in use.

ATTENTION:
-
as the insulation used may obstruct the convection
cooling airways around the rim of the cartridge enclosure and cause
the mantle to overheat.
It is not recommended to leave any heating apparatus unattended
during operation.
Only use Original Equipment manufactures spares and accessories.
Ref Section 10.
The equipment is not spark, flame or explosion proof and has not been
designed for use in hazardous areas in terms of BSEN 6007914:1997. Keep flammable, low flash point substances away from the
apparatus.
Keep the mains cord away from the heating surface.
thermally insulate the exposed upper section of the vessel(s),
operate or handle any part of the product with wet hands.
With high energy input and certain configurations of glassware in MQ
products, where the heating contact to glassware is relatively small,
localised heating and subsequent ‘bumping’ of the fluid being heated
may occur. Application advice should be sought from the
manufacturer.
