Test Tubes and Thermometer Pockets Manufacturer, Suppliers and Exporter in India

Jlabexport is a leading Test Tubes and Thermometer Pockets Manufacturer,and suppliers in India

Test tubes and thermometer pockets in this category are ground-joint glassware components for building and monitoring laboratory assemblies. The range covers jointed test tubes with sockets, angled drying tubes, bent and straight air inlets, thermometer pockets and thermometers with a cone fitting. Jlab Export manufactures and exports these items from Ambala, India, for school, university, TVET, research and industrial laboratories.

Every item in the category is specified by its joint size. Test tubes are listed by capacity, height, diameter and socket size; drying tubes, air inlets and thermometer pockets are listed by cone size and, where applicable, stem length; thermometers are listed by temperature range and cone size. Selection is therefore a joint-compatibility exercise before it is a capacity one.

Materials of construction, wall thickness, scale division, accuracy class and pack quantities are not published in this category and are available on request.

What is included in this category?

The category lists six items under product codes JL-TTATP-1694 to JL-TTATP-1699. These are: Laboratory Test Tubes, Tubes Drying Angled, Tubes and Air Inlets Bent With Cone, Tubes and Air Inlets Straight With Cone, Thermometer Pockets, and Thermometers With Cone.

Despite the category name, four distinct component families sit here. Test tubes are jointed reaction and containment vessels. Drying tubes and air inlets are gas-handling components that connect to an assembly through a cone. Thermometer pockets are sheaths that hold a thermometer inside a vessel. Thermometers with cone are the measuring instrument itself.

Each product page carries its own size table. The tables are reproduced in full below so a buyer can check joint compatibility across the whole category in one place.

How do you choose a jointed test tube?

Choose a jointed test tube by matching four figures: required capacity, tube height, tube diameter and socket size. The socket must match the cone on the stopper, adapter or component that will close the tube. Ten sizes are listed, from 2 ml to 195 ml.

The listed sockets are B10, B14, B19, B24 and B34. Capacity does not scale with a single dimension: the 19 ml tube is offered both at 100 mm height with a 23 mm diameter and B19 socket, and at 150 mm height with an 18 mm diameter and B14 socket. Height, diameter and socket therefore need to be specified together, not inferred from capacity alone.

Confirm the socket size against the closure or component being used before ordering.

What is the difference between an air inlet and a drying tube here?

Air inlets are straight or bent tubes with a cone that introduce gas into an assembly; the listed drying tubes are angled and are also specified by cone size only. Straight air inlets have a 100 mm stem; bent air inlets have a 150 mm stem. Angled drying tubes are listed without a stem length.

Cone coverage differs between the three. Straight air inlets and angled drying tubes are both offered in B10, B14, B19, B24 and B29. Bent air inlets are offered only in B14, B19 and B24 — there is no B10 or B29 bent version listed.

If an assembly requires a B10 or B29 connection with a bend, confirm availability before specifying, or plan the assembly around a straight inlet.

How do thermometer pockets and thermometers work together?

A thermometer pocket is a closed sheath that seats in the vessel joint and holds a thermometer, so temperature can be read without exposing the instrument to the contents. The pocket connects by its cone; the thermometer sits inside the pocket bore rather than joining to it.

Two pockets are listed: a 45 mm stem with a B14 cone, and a 200 mm stem with a B19 cone. All four thermometers carry a B14 cone. Because the cone on a pocket and the cone on a thermometer both mate to a socket, they do not join to each other — the thermometer is inserted into the pocket bore.

The internal bore diameter of the pockets is not published. Confirm that the intended thermometer fits the chosen pocket before ordering the two as a pair.

Which temperature ranges are available?

Four ranges are listed for the thermometers with cone: 0–110 °C, 0–200 °C, 0–300 °C and 0–400 °C. All four are supplied with a B14 cone. No other cone size is listed for a thermometer in this category.

The listings do not state the scale division, accuracy class, immersion type (total or partial), overall length or the liquid used in the bulb. Those figures determine whether a thermometer is fit for a given procedure, and for institutional or calibrated use they are usually mandatory.

Request the full instrument specification, including any calibration certificate, before the thermometers are quoted into a laboratory list or tender.

How should a school, TVET or research laboratory specify these items?

Send the joint size first for every line, then the dimension that matters for that item: capacity, height and diameter for test tubes; stem length for air inlets and pockets; temperature range for thermometers. State the vessel or assembly each component must connect to.

Because material, wall thickness, scale division and pack quantity are not published, list those requirements in the enquiry rather than assuming them. For thermometers, state the required accuracy, division and immersion condition, and whether a calibration certificate is needed.

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

Frequently asked questions

What sizes of laboratory test tube are available?

Ten sizes are listed, from 2 ml to 195 ml. Heights run from 65 mm to 250 mm and diameters from 14 mm to 41 mm. Each size carries a ground socket: B10, B14, B19, B24 or B34. Capacity should always be specified together with height, diameter and socket size.

Are these test tubes plain or jointed?

Every test tube listed in this category carries a ground socket, so they are jointed tubes intended to connect to a stopper, adapter or other component. Plain rimmed or rimless test tubes are not listed here. If plain tubes are needed, raise a separate enquiry so the correct item is quoted.

What is a thermometer pocket used for?

A thermometer pocket is a sheath that seats in a vessel joint and holds a thermometer, allowing temperature to be read without exposing the instrument to the vessel contents. Two are listed: a 45 mm stem with a B14 cone and a 200 mm stem with a B19 cone.

Will any of these thermometers fit the thermometer pockets?

All four thermometers carry a B14 cone, but the pocket bore diameter is not published, so fit cannot be confirmed from the listed data. Buyers intending to use a thermometer inside a pocket should ask Jlab Export to confirm the pocket bore and the thermometer outside diameter before ordering.

What is the difference between the bent and straight air inlets?

The straight air inlets have a 100 mm stem and are offered in B10, B14, B19, B24 and B29 cones. The bent air inlets have a 150 mm stem and are offered in B14, B19 and B24 only. There is no bent version listed in B10 or B29.

What material are these items made from?

The material of construction is not stated on the category or product pages, and no wall thickness or thermal rating is published. Buyers should request the material specification, together with any temperature or chemical-compatibility limits, for each item being quoted. Specifications are available on request.
