Laboratory glass joints are the ground-glass connections that let flasks, condensers, columns, adapters and receivers be assembled into a leak-resistant apparatus and taken apart again. Laboratory Glassware Ambala manufactures and exports cone joints, cone joints with a drip tip, socket joints, double socket joints and spherical ball and cup joints, together with polypropylene clips for securing taper joints. They are bought by school, college and university laboratories, research and industrial laboratories, government institutions, NGOs, distributors, importers, project consultants and educational procurement agencies. Because a joint is specified by its system and its size designation, and neither is currently published on the product records, this page sets out exactly what to confirm in writing before an order is placed.

Taper joints and spherical joints are two separate systems

These are the ordinary meanings of the two systems, given so that a buyer can specify correctly. What is supplied against any line should still be confirmed with the company.

In a taper system, a conical male half — the cone — seats inside a matching female half, the socket, and the pair is usually secured with a clip or clamp. The size is written as two numbers describing the taper, and a cone and socket only mate if both carry the same designation. In a spherical system, a ball seats into a cup or socket and is held by a pinch clamp; the connection tolerates a degree of angular misalignment, which is why it is used where two pieces of apparatus cannot be brought perfectly into line. Spherical sizes are designated differently from taper sizes.

The two systems do not connect to each other, and a joint from one cannot be substituted for a joint from the other. Establish which system the existing apparatus uses before ordering.

Why the size designation belongs on the order and on the glass

No size designation is published for any product in this category, and three of the seven are described as unprinted. Those two facts together have a practical consequence worth planning around: a buyer cannot select a size from the catalogue, and if the joints supplied carry no printed marking, the size cannot be read off the item on arrival either. A consignment of mixed unmarked cone joints has to be gauged before it can be sorted or issued to a laboratory.

Two things to settle in writing before ordering. First, ask for the full list of taper and spherical sizes produced, and state the size required against every line of the order rather than ordering by product name. Second, ask whether joints can be supplied with the size designation permanently marked on the glass, and if so, how the marking is applied — this is worth specifying even at a small price difference where joints will be stored loose or issued across several laboratories.

Which specifications should be confirmed before ordering?

Selection criterion	What to confirm for each line
Joint system	Taper cone and socket, or spherical ball and cup
Size designation	The exact size for each line, in the convention used for that system, and the full range of sizes available
Which half	Whether the item is the male half (cone or ball) or the female half (socket or cup), since these are ordered separately
Marking	Whether the size designation is printed or otherwise permanently marked on the glass, and by what method
Drip tip	Whether a drip tip is fitted, and its form
Free end	The configuration of the end opposite the joint — open tube, drip tip or otherwise — and its outside diameter, which matters where joints will be sealed onto other glassware
Glass type	The glass grade used, which is not stated on any record in this category
Wall thickness	The wall thickness at the joint and along the stem
Clip and clamp fit	The joint size each Keck clip is made for, confirmed against the joints being ordered, and what clamp the spherical joints require
Sealing method	Whether the joints are intended to be used greased, ungreased or with a sleeve, and whether sleeves or grease are supplied
Packing	Quantity per pack and per carton, and the export packing used for glass items
Documentation	Any material or dimensional certificate the institution requires with the consignment

Matching joints across an apparatus

A joint is only useful if it mates with the item at the other end of the assembly. Where an order covers joints alongside condensers or other glassware from this website, the size designation should be fixed once and applied across the whole schedule, because sizes are not published on those product records either. Stating the sizes already in use in the laboratory, and asking for written confirmation line by line, is quicker than resolving a mismatch after delivery.

Applications and buyer groups

Glass joints are used to build and modify distillation, reflux, extraction and filtration assemblies, to adapt apparatus between glassware of different origins, and as replacement parts when a joint on an existing piece is damaged. They are bought by school and college practical laboratories, university teaching and research laboratories, industrial and quality-control laboratories, glassblowing and repair workshops, and institutional laboratory fit-outs. Replacement joints are usually ordered against a specific existing apparatus, so the size and the half required should be identified before the enquiry is sent.

Institutional and export enquiries

Laboratory Glassware Ambala accepts bulk laboratory-supply and tender enquiries through its contact and tender pages, and a schedule may combine joints with other laboratory glassware. Institutional procurement support does not imply approval, accreditation or endorsement by any ministry, government authority, development bank, United Nations agency or funding organization.

Frequently asked questions

Which joint sizes are available?

Sizes are not published on the product records, so the full list of taper and spherical sizes should be requested and confirmed on the quotation before ordering.

What does "Unprinted" mean on some of these products?

The term is not defined on the records. Confirm whether it indicates that the size designation is not marked on the glass, and whether a marked version can be supplied.

Will the spherical joints connect to the cone and socket joints?

No. Taper and spherical joints are separate systems that do not mate with each other, so confirm which system the existing apparatus uses before ordering either.

Are clips supplied with the joints?

Clips are listed as a separate product. Confirm the joint size each clip is made for, and order clips against the same size designation as the joints.
