Connection System for Duran Laboratory Bottles
Description
Connection System with screw cap and 2 or 3 GL 14 ports, PP, blue/grey
Manufactured from Polypropylene
Rigid or semi-rigid tubing of different diameters can be accepted by using a blue GL 14 open topped cap with one of the inserts.
Available with 2, or 3 threaded outlets (ports).
Four different tubing diameters (1.6 mm, 3.0 mm, 3.2 mm or 6.0 mm tubing outer diameter) can be used by changing the GL 14 inserts.
By applying positive or negative pressure liquid can be pumped out of or into the bottle via the screw cap.
Fully compatible with all the GL 45 threads and therefore highly versatile.
Glass Sintered Discs
Description
Riviera Filter Crucible with Sintered Disc
Manufactured from 3.3 expansion borosilicate glass
Fitted with an integral glass sintered disc available in different porosities (grades)
Flat bottomed, so the crucible can be safely set down on a flat surface
A range of different size glass crucible adapters and rubber adapter sleeves are available for use with these crucibles

Silica Ware
Description
CHEMICAL PROPERTIES-
Fused Silica is neutral to all halogens and acids irrespective of temperature or concentration except hydro-fluoric and phosphoric acid. Phosphoric acid affects fused silica only at high temperatures and can be concentrated successfully in silica vessels. For all ordinary purposes they can be used with phosphoric acid. Sulphuric, Nitric and Hydrochloric acids or any mixture of these acids, do not affect Fused Silica even at temperatures upto 1000ºC. Cleaning of Silica ware regularly can ensure good service.
Quartz Ware
Description
Vitreous Silica is the glassing modification of silcon dioxide with a purity of 99.9% in the transparent form and is called fused silica. All our silica ware products are made out of fused silica. Fused silica is completely unaffected by acids such as sulpuric, nitric and hydrochloric, however, it can be affected by hdrofluric acid and at high temperatures also by phosphoric acid. Hot alkalies and certain metallic oxides also react on fused silica.
Fused silica is boron free
They are of very low expansion and hence have excellent dimensional stability and thermal shock resistance
