Joints, Cone with Tip — JL-SDAJ-1677
Joint Clips, Plastic — JL-SDAJ-1678

Material composition, tolerances, packing quantities and product-specific standards are not consistently stated in the individual listings. These details should be requested before ordering.

How do you select a spherical laboratory joint?

Select a spherical joint by first choosing the required male or female configuration and then matching the listed spherical-joint size. Jlab Export lists both configurations with a 100 mm shank length and options identified as S13 Capillary Bore, S13, S19, S29, S35, S41 and S51.

The available products are:

Female spherical joint — JL-SDAJ-1669
Male spherical joint — JL-SDAJ-1670

The male and female listings should be checked together when specifying mating components. Buyers should state the required product code, spherical size and quantity in the enquiry.

The listings do not provide dimensional tolerances, material grade, wall thickness, working pressure or vacuum rating. Where these parameters affect compatibility or operating conditions, request a current technical datasheet and written confirmation from the manufacturer.

How do you choose a screwthread joint?

Choose a screwthread joint by matching the screwthread size, minimum bore and required shank length. Product JL-SDAJ-1671 has a listed 110 mm shank length, with screwthread sizes 13, 14, 18, 24, 25, 28 and 32 and minimum bores ranging from 7.5 mm to 26.0 mm.

The individual listing gives the following specification combinations:

Screwthread size	Shank length	Minimum bore
13	110 mm	7.5 mm
14	110 mm	7.5 mm
18	110 mm	10.5 mm
24	110 mm	15.5 mm
25	110 mm	20.0 mm
28	110 mm	19.7 mm
32	110 mm	26.0 mm

Buyers should use the exact listed combination rather than selecting only by thread number. Thread profile, material, cap compatibility and tolerance information should be requested where required.

What flat-flange joint sizes are listed?

Jlab Export lists flat-flange joint JL-SDAJ-1672 in five bore and flange-diameter combinations. The available bore diameters are 10, 25, 50, 75 and 100 mm, paired with flange diameters of 30, 55, 85, 120 and 150 mm respectively.

Bore diameter	Flange diameter
10 mm	30 mm
25 mm	55 mm
50 mm	85 mm
75 mm	120 mm
100 mm	150 mm

A buyer should specify both dimensions because the bore and flange diameter form one listed configuration. The listing does not state flange thickness, sealing arrangement, surface finish, clamp requirements or included accessories.

Where the flat-flange joint must connect to an existing apparatus, compatibility should be confirmed using a drawing, sample, existing component specification or approved technical datasheet before production.

How do you select economy or premium-brand sintered discs?

Select a sintered disc by specifying the listed product range, disc diameter and porosity number. Both the Economy Range and Premium Brand listings show diameters of 10, 20, 30, 40, 50, 60, 65 and 90 mm, with porosity options 0, 1, 2, 3 and 4 for each diameter.

The two products are:

Economy Range Sintered Discs — JL-SDAJ-1673
Premium Brand Sintered Discs — JL-SDAJ-1674

The online specifications do not explain the technical difference between the Economy Range and Premium Brand ranges. Material grade, disc thickness, pore-size range, filtration performance and chemical or thermal suitability are also not stated.

Buyers should therefore include the required diameter, porosity number, quantity and application requirements in the quotation request. The distinction between the two ranges should be confirmed through current manufacturer documentation rather than inferred from the product names.

What cone and socket joint sizes are available?

Single cone and single socket joints are listed with a 110 mm shank length in sizes B7, B10, B12, B14, B19, B24, B29, B34, B40, B45, B50 and B55. Cone joints with tips have a 90 mm shank length and are listed from B10 to B55.

The relevant product codes are:

Joints, Cone, Single — JL-SDAJ-1675
Joints, Socket, Single — JL-SDAJ-1676
Joints, Cone with Tip — JL-SDAJ-1677

Cone-with-tip sizes listed are B10, B14, B19, B24, B29, B34, B40, B45, B50 and B55.

Buyers should confirm that the selected cone and socket designations correspond to the intended mating components. Tip dimensions, bore, material, tolerances and connection geometry are not supplied in the online listings and should be requested where relevant.

Which joint clip sizes are listed?

Plastic joint clips, product code JL-SDAJ-1678, are listed for joint sizes B10, B14, B19, B24, B29 and B34. Buyers should select the clip according to the stated joint size and confirm compatibility with the joint components included in the same order.

The listing confirms that the clips are described as plastic but does not identify the specific polymer, temperature limits, chemical resistance, colour, closure design or packing quantity.

For institutional or export orders, the enquiry should include:

Product code JL-SDAJ-1678
Required joint size
Quantity
Related cone or socket product code
Packing requirements
Delivery destination

When clips are ordered for existing equipment rather than with new joints, buyers should provide the existing joint designation or a sample for compatibility confirmation.

Who can procure screwthreads, discs and laboratory joints?

The category is intended for schools, universities, TVET institutions, research laboratories and industrial users. Product selection should be based on the required component type and the dimensional information stated in the individual product listing, rather than education level alone.

School and university buyers may require replacement or assembly components for laboratory glassware. TVET institutions may include the components in practical laboratory or technical-training procurement. Research and industrial buyers may require more detailed dimensional, material or operating data before approval.

Jlab Export states that it exports to markets across Asia, Africa, Europe, North and South America, and Oceania. The company also states that equipment may be customized for particular institutional or industrial requirements, subject to confirmation for the selected product.

What should buyers include in a quotation request?

A quotation request should identify the product name, JL-SDAJ code, exact size, quantity, destination and required technical documentation. For items with multiple dimensional fields, buyers should quote the complete specification combination shown in the listing instead of providing only one dimension.

Useful enquiry details include:

Product name and product code
Male, female, cone, socket or flange configuration
Joint, thread or flange size
Shank length
Minimum bore, where applicable
Disc diameter and porosity
Quantity
Intended application
Required material or tolerance
Packing and marking instructions
