Specimen Tubes and Vials Manufacturer, Suppliers and Exporter in India

Jlabexport is a leading Specimen Tubes and Vials Manufacturer,and suppliers in India

Specimen tubes and vials are small closed containers used to hold, store and transport samples, reagents and prepared solutions in the laboratory. Jlab Export manufactures and exports a range of screw-neck, rolled-rim and wide-mouth vials in neutral glass, plus flat-bottom tubes in soda glass, from Ambala, India, for school, university, TVET, research and industrial laboratories.

Six items are listed. The vials are specified by nominal dram size, capacity in millilitres, height and diameter, and are supplied with a closure. The flat-bottom tubes are specified by length and diameter. Capacities run from 1.75 ml to 28.25 ml across the vial range.

Two glass types are named in the product listings: neutral glass for the vials and soda glass for the tubes. No further material grade, hydrolytic class, wall thickness, closure material or pack quantity is published, and these should be confirmed by quotation.

This category does not list evacuated blood collection tubes, cryovials, micro-centrifuge tubes or sample containers for clinical specimen transport.

What is listed in this category?

Six products are listed under codes JL-STAV-1679 to JL-STAV-1684: a flat-bottom tube listing in soda glass, tall screw-neck vials, squat screw-neck vials, two rolled-rim vial listings, and wide-mouth vials with a push-in plug closure. All the vials are neutral glass and supplied with a closure.

Four vial forms are therefore available: tall screw neck, squat screw neck, rolled rim and wide mouth. The form determines the height-to-diameter ratio at a given capacity and the type of closure, which in turn affects rack fit, storage density and how the container is opened.

Full size tables for every item are reproduced below.

How do you choose between the vial forms at the same capacity?

Choose by the height and diameter you need, not by capacity alone. The same nominal capacity is offered in different proportions across the forms. A 2-dram, 7 ml vial is 58 × 17 mm as a tall screw neck, 42 × 20 mm as a squat screw neck, and 34 × 23 mm as a rolled rim.

Tall narrow vials suit deep racks and small benchtop footprints. Squat wide vials are more stable, easier to fill and easier to reach into with a spatula or pipette. Rolled-rim vials are the shortest and widest of the three at equal capacity.

Check the diameter against your rack, tray or carton before ordering, since the choice affects how many fit a given space.

What closure types are listed?

Two closure types appear in the product titles: screw closures on the tall and squat screw-neck vials, and a push-in plug on the wide-mouth vials. The rolled-rim vials are listed as supplied with a closure, without the closure type being named.

Closure material, liner or wad material, and seal performance are not published for any item. Where the contents are volatile, corrosive or intended for extended storage, these details should be requested for the exact item quoted.

The flat-bottom tube listing appears under a title referring to push-in caps, but its size table lists tubes rather than caps — see the note in the product table below.

What sizes of flat-bottom tube are available?

Twelve sizes are listed, given as length × diameter in millimetres: 38 × 10, 50 × 10, 38 × 12, 50 × 12, 75 × 12, 50 × 15/16, 75 × 15/16, 50 × 18/19, 75 × 18/19, 50 × 25/26, 75 × 25/26 and 100 × 25/26.

The paired diameters (15/16, 18/19, 25/26) indicate a diameter range rather than a single figure, which is normal for drawn soda-glass tubing. Confirm the tolerance if the tube must fit a specific rack, centrifuge insert or cap size.

No capacity in millilitres is published for these tubes, only external dimensions.

What should a school, TVET or research laboratory specify when enquiring?

State the vial form, nominal capacity or dram size, height and diameter, and closure type for each line, plus quantity. For flat-bottom tubes, state the length and diameter. Add the material grade, closure material and pack quantity requirements, since none of these are published.

Where vials are used for sample storage, state the storage temperature and duration and the contents involved, so a suitable glass and closure can be identified rather than assumed.

For tender and bulk orders, supply the full bill of quantities, the destination, packing and carton-marking requirements, and any mandatory documents.

What is not covered by this category?

Evacuated blood collection tubes, additive tubes, cryovials, micro-centrifuge tubes, universal sputum or urine containers, and packaging for the transport of infectious or diagnostic substances are not listed here. Nothing in this category is presented as a medical device or in-vitro diagnostic product.

Laboratories procuring clinical specimen collection or transport consumables should raise a separate enquiry, and should expect regulatory documentation appropriate to those product classes rather than a general labware quotation.

The vials listed here are general laboratory containers for samples, reagents and prepared solutions.

Frequently asked questions

What capacities of vial are available?

Vials are listed from 0.5 dram (1.75 ml) to 8 dram (28.25 ml). The tall screw-neck form covers the widest range with seven sizes; rolled rim offers five, squat screw neck three, and wide mouth three. Not every capacity is available in every form — check the size table above.

What is the difference between a tall and a squat vial?

At the same capacity, a tall vial is narrower and higher, and a squat vial is wider and shorter. A 4-dram, 14 ml vial is 72 × 20 mm in the tall screw-neck form and 58 × 23.25 mm in the squat form. Tall vials suit deep racks; squat vials are more stable and easier to fill.

What glass are the vials made from?

The vials are described as neutral glass and the flat-bottom tubes as soda glass in the product listings. No hydrolytic class, USP or ISO glass type, wall thickness or thermal rating is published. Request the full material specification for the exact item before ordering, particularly for storage or heating applications.

Are the closures included?

Yes — all four vial listings state that a closure is supplied. The tall and squat screw-neck vials use a screw closure and the wide-mouth vials a push-in plug. The closure type is not named for the rolled-rim vials, and no closure or liner material is published for any item.

Do you supply blood collection tubes or clinical specimen containers?

No. This category lists general laboratory vials and glass tubes. Evacuated blood collection tubes, additive tubes, cryovials, micro-centrifuge tubes and containers for clinical specimen transport are not listed here, and nothing in this category is offered as a medical device or in-vitro diagnostic product.

What is the smallest and largest item listed?

The smallest vial is 0.5 dram at 1.75 ml, offered at 36 × 11 mm (tall screw neck) and 36 × 11.5 mm (wide mouth). The largest is 8 dram at 28.25 ml, offered at 96 × 23 mm (tall screw neck), 72 × 27.5 mm (squat) and 72 × 27 mm (rolled rim). The largest tube listed is 100 × 25/26 mm.
