Burettes Manufacturer, Suppliers and Exporter in India

Jlabexport is a leading Burettes Manufacturer,and suppliers in India

Laboratory burettes are glass instruments graduated for dispensing volumes of liquids through titration and other laboratory measurements. The purpose of the following category is to target school, university, and TVET burettes purchases by capacity, glass type, stopcock arrangement, graduation, and replacement key.

Jlab Export manufactures and exports laboratory burettes from Ambala, India. The Burettes category currently consists of two items: a borosilicate glass burette with a PTFE stopcock and a borosilicate glass burette which is commonly called a burette with an all PTFE stopcock. Both the products have a volume capacity of 50 ml. Additionally, the listings JL-B-1593 feature blue enamel graduations and replacement keys.

According to Jlab Export, their products reach markets globally, including those from Asia, Africa, Europe, North America, South America, and Oceania.

What products are included in the Burettes category?

The current category contains two 50 ml borosilicate-glass burettes differentiated by their stated PTFE stopcock configurations. Buyers should specify the exact product code because the individual listings provide different levels of construction and replacement-key information.

The listed products are:

• Burette, Borosilicate Glass, with PTFE Stopcock — JL-B-1593
• Burette, Borosilicate Glass, with all PTFE Stopcock — JL-B-1594

Both listings state a capacity of 50 ml. JL-B-1593 additionally states that:

• Graduations are finished in easy-to-read blue enamel.
• Replacement keys are available if a key is lost or damaged.
• The keys are fully interchangeable.
• The burette is manufactured from borosilicate glass.

The JL-B-1594 page confirms its name, product code and 50 ml capacity but does not provide further dimensional, graduation or stopcock-construction details.

How do you choose a laboratory burette?

Choose a laboratory burette by confirming the required capacity, stopcock configuration, graduation specification, accuracy class and delivery tolerance. Jlab Export currently lists two 50 ml models, but numerical tolerance, graduation interval and calibration details are not stated on their individual pages.

A procurement enquiry should identify:

• Product code JL-B-1593 or JL-B-1594
• Required capacity: 50 ml
• PTFE stopcock configuration
• Required accuracy class
• Graduation interval
• Numerical tolerance
• Calibration temperature
• Required delivery or containment calibration
• Graduation colour
• Quantity and packing requirements

The product name alone is insufficient where a school, university, research laboratory or industrial method requires a particular tolerance or stopcock construction. Specifications not confirmed online should be requested in writing.

What is confirmed for burette JL-B-1593?

JL-B-1593 is a 50 ml borosilicate-glass burette with a PTFE stopcock, blue-enamel graduations and interchangeable replacement keys. The listing states that replacement keys are available in the event of loss or damage.

Confirmed details are:

The page does not state the graduation interval, numerical tolerance, overall length, tube diameter, tip dimensions, stopcock bore, calibration temperature, accuracy class or packing quantity. These fields should be confirmed before technical approval.

What is confirmed for burette JL-B-1594?

JL-B-1594 is listed as a 50 ml borosilicate-glass burette with an “all PTFE stopcock.” The individual page confirms the product code and capacity but does not explain the construction covered by the term “all PTFE stopcock.”

Confirmed details are:

Buyers should request written confirmation of:

• Which stopcock components are PTFE
• Stopcock bore and plug dimensions
• Replacement-key availability
• Graduation colour and interval
• Accuracy class and tolerance
• Tip construction
• Overall burette dimensions
• Packing quantity

Details stated for JL-B-1593 should not automatically be applied to JL-B-1594.

How do the two listed burettes differ?

The confirmed difference is the product description: JL-B-1593 has a PTFE stopcock, while JL-B-1594 is described as having an all-PTFE stopcock. Both are listed as 50 ml borosilicate-glass burettes, but only JL-B-1593 has additional information about graduations and replacement keys.

A buyer should not assume that the second model has the same graduations, tolerance or replacement-key system. Request separate datasheets for both products when comparing them.

What graduation details should buyers verify?

Buyers should verify the graduation interval, total graduated range, line colour, numbering pattern and numerical tolerance. JL-B-1593 confirms blue-enamel graduations, but neither product page states the scale division or accuracy class.

Important fields include:

• Graduation interval in millilitres
• Numbered graduation frequency
• Zero position
• Total graduated range
• Class A or Class B designation
• Capacity tolerance
• Drainage or waiting time
• Calibration temperature
• Marking permanence

These details affect technical compliance and should appear in the quotation or datasheet where the buyers BOQ specifies volumetric accuracy. A category-level reference to a standard does not replace product-specific tolerance data.

What should buyers check about the PTFE stopcock?

Buyers should confirm the stopcock bore, plug design, retaining arrangement, tip construction and availability of replacement parts. The JL-B-1593 page confirms interchangeable replacement keys, while the JL-B-1594 page does not provide equivalent replacement-key information.

Request confirmation of:

• Stopcock body and plug materials
• Whether a retaining nut or device is included
• Bore diameter
• Leak-control specification
• Key interchangeability
• Replacement-key ordering reference
• Tip design
• Cleaning instructions
• Chemical compatibility
• Recommended operating temperature

The phrase “all PTFE stopcock” requires a component-level explanation before it can be used as a technical differentiator.

How should schools, universities and TVET institutions select burettes?

Educational institutions should select burettes according to the practical schedule, required accuracy and number of laboratory workstations. Both displayed Jlab Export models have a stated capacity of 50 ml, so the main online distinction is their stopcock description.

An educational procurement request should include:

• Required product code
• Capacity
• Accuracy class
• Graduation interval and tolerance
• Stopcock configuration
• Quantity per laboratory
• Replacement-key requirement
• Stand and clamp requirements
• Packing and documentation requirements

Where the equipment list states only “50 ml burette,” the buyer should ask Jlab Export to identify the proposed product code and declare any unconfirmed or deviating specification.

What should research and industrial buyers verify?

Research and industrial buyers should verify numerical tolerance, calibration details, chemical compatibility and stopcock performance before approving a burette. The individual pages do not provide enough data to determine method-specific volumetric compliance.

Request written confirmation of:

• Accuracy class
• Numerical tolerance at 50 ml
• Graduation interval
• Calibration temperature
• Delivery calibration
• Drainage or waiting time
• Glass type and grade
• Stopcock leak specification
• Chemical resistance
• Overall length and tube diameter
• Traceability or calibration documents, where required

Any product-specific standard should be supported by a certificate, declaration or datasheet naming JL-B-1593 or JL-B-1594.

What should institutional and tender buyers include in an enquiry?

Institutional and tender buyers should submit the complete BOQ description, product code, capacity, accuracy requirement, stopcock configuration, quantity, destination and documentation requirements. Jlab Export states that its tender service provides line-by-line quotations, technical datasheets, compliance documentation and export-grade packing for applicable orders.

Include:

• Tender or project reference
• Product code
• Capacity
• Accuracy class
• Graduation interval and tolerance
• Calibration requirement
• Stopcock and tip specification
• Replacement-key requirement
• Quantity
• Inspection conditions
• Packing and carton marking
• Delivery country
• Certificate or declaration requirements
• Submission deadline

Certificate copies supplied with quotations are manufacturer-stated and should be checked by the buyer for scope and applicability.
