Beschrijving
BOLA flat ground joint connection NW 170/146 is an aluminium coupling component for joining a flat ground joint reaction vessel to a matching flat ground joint lid. The connection is secured with eight galvanised steel screws, providing a stable mechanical clamp around the flange interface. It is dimensioned specifically for flange nominal width NW 170/146 and supports reliable assembly of plan-flange reaction systems used in laboratory synthesis, process development and controlled heating setups. Net weight is 1,152 kg. The aluminium construction offers a rigid frame for repeated opening and closing cycles while the galvanised fasteners maintain clamping force under typical lab handling. This single-piece accessory from manufacturer Bohlender complements BOLA plan-flange vessels and lids of the corresponding NW size and is intended for use wherever a defined, screw-secured flat-flange joint is required between vessel and cover.
This article is part of Ground-joint glassware (other), in Distillation & extraction glassware.

Questions about BOLA Flat Flange Joining Pieces, NW 170 / 146 170 / 146
What is this article?
BOLA Flat Flange Joining Pieces, NW 170 / 146 170 / 146 is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in Ground-joint glassware (other), inside Distillation & extraction glassware, in Labmateriaal.
This is ground-joint glassware that is not a head, a condenser or a Soxhlet: receivers, blank joints, odd adapters. A ground joint is named by the wide end and the length, such as 29/32. Mismatched joints do not seal, even with grease.
Distillation separates liquids by boiling point. A condenser turns the vapour back into liquid: Liebig, coil and cold-finger shapes differ in how much cooling surface they offer. A still head and a column sit between the flask and the condenser. A Soxhlet extractor washes a solid again and again with the same solvent. Ground joints have a standard size, and the joint, not the flask, is what has to match. The pieces are indexed under ISO laboratory glassware.
