Conductivity Demonstrator (Product Code: SLE/CH/99) is a simple classroom apparatus that shows at a glance whether a liquid conducts electricity. Two platinum electrodes are mounted on a non-conductive support together with a light globe and terminals; connected to a power source and dipped into a solution, the globe glows when the liquid carries a current and stays dark when it does not. Science and chemistry teachers in middle and secondary schools use it to separate electrolytes from non-electrolytes in front of the whole class. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a school laboratory equipment supplier in India.

Specifications

Typical Use

Connect the terminals to a battery pack or 6V power supply, then lower the electrodes into a beaker of the test liquid. Salt solution or dilute acid lights the globe, while distilled water or sugar solution leaves it dark, which gives students a clear, visual contrast between ionic and molecular substances. Comparing the brightness across several solutions also opens a discussion of strong and weak electrolytes.

Rinse the electrodes in distilled water and blot them dry between samples so one solution does not contaminate the next, and disconnect the power before changing beakers. Platinum is chosen for the electrodes because it resists attack by the acids and salt solutions being tested. A chemistry lab instruments supplier can quote the demonstrator together with beakers and leads so the activity is ready to run.

Manufacturer

The Conductivity Demonstrator comes from Jain Scientific Equipments Private Limited, which operates under the ScienceLab name in Ambala, Haryana, India, producing science teaching apparatus. See our company profile for more about the business.

Pipeclay Triangle (Product Code: SLE/CH/100) is a heating support used in laboratories when a substance must be heated directly over a Bunsen burner. The substance, usually held in a crucible or small dish, is placed in the triangle framework, which rests across a tripod or retort ring so the flame can reach the base of the vessel. It is a routine item in school and college chemistry practicals such as heating salts, igniting precipitates and burning metals in air. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, as part of its school chemistry lab equipment for India and international buyers.

Key Details

Typical Use

Set the triangle on a tripod or retort ring, seat the crucible so it sits securely in the framework with part of its body below the triangle, and light the Bunsen burner beneath. Classic practicals include heating hydrated copper sulphate to drive off water of crystallisation, heating magnesium ribbon in a lidded crucible to find the formula of its oxide, and igniting a filtered precipitate to constant mass in gravimetric analysis.

Choose a triangle that matches the crucible size so the vessel neither falls through nor perches on top. Lift hot crucibles with tongs, let the triangle cool in air on a heat-resistant surface, and never plunge it into water, as sudden cooling can crack it. Flat-bottomed glassware such as beakers belongs on a wire gauze instead. Schools buying chemistry lab equipment in India usually order triangles, tripods and crucibles together as a heating set.

Manufacturer

Jain Scientific Equipments Private Limited carries out business as ScienceLab from Ambala, Haryana, India, manufacturing apparatus for school, college and technical laboratories. More information is available in our company profile.

Digital Stopclock (Product Code: SLE/ME/41) is a battery-powered digital timer used to time physics and general science experiments to 1/100 second in school and college laboratories. Its large 12 mm high display and front-panel 4 mm sockets, which let start/stop and reset be triggered externally as well as from the top-mounted push switches, set it apart from a handheld stopwatch. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, among its physics lab instruments.

Specifications

What Is the Digital Stopclock Used For?

A stopclock with a display the whole bench can read is ideal for timing pendulum swings, trolley runs down a ramp, falling objects, cooling curves and the rate of simple chemical reactions. The split (lap) function records an intermediate time without stopping the count, so students can note, for example, the time for ten oscillations and then twenty in a single run.

The 4 mm sockets make it possible to wire the stopclock to external switches or contacts, so the clock starts and stops at the exact moment an event happens rather than when a student reacts. This reduces human reaction-time error and is a good way to introduce the idea of systematic error in physics lab instruments work in India's schools and colleges.

What to Specify When Ordering

• Number of stopclocks needed per laboratory or group.
• Whether AA/R6 or HP7 cells should be included with your order.
• Whether you plan external switching through the 4 mm sockets, or light-gate timing, so we can advise on suitable accessories.

Digital Melting Point Apparatus (Product Code: SLE/ME/43) is a bench instrument used to determine the melting point of solid samples in chemistry, pharmacy and teaching laboratories. It heats two samples at once from ambient to 300 °C, climbing at 20 °C per minute to a chosen plateau and then at 2 °C per minute through the melt, with a PT100 sensor and a large three-digit LED readout. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is a Digital Melting Point Apparatus Used For?

Melting point is one of the quickest checks on the identity and purity of a crystalline solid: a pure compound melts sharply near its literature value, while impurities lower and widen the melting range. Students use this apparatus to confirm products they have synthesised or recrystallised, to compare an unknown with reference compounds, and to see how a mixed melting point shows whether two samples are the same substance. With two sample positions, an unknown and a reference can be run side by side.

In practice the block is first taken quickly to a plateau a little below the expected melting point, where it waits until the operator is ready; the slower 2 °C per minute ramp then gives time to watch the crystals collapse and note the temperature. Load finely ground, dry sample to a short, even depth in each tube, and set the extendable feet so the view through the cover is comfortable. The three status LEDs help students follow each stage of the test.

Supplier

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, which supplies this Digital Melting Point Apparatus from Ambala, Haryana, India. Working as a chemistry lab instruments supplier, the company quotes it for colleges, pharmacy institutes, testing laboratories and dealers in India and international markets, together with melting-point tubes and small lab items if required. Read more on the company profile.

Related Measuring Equipment

Items used to prepare and run melting point tests, plus alternative models:

• Melting-Point Tubes — the tubes that carry samples into the heating block.
• Porcelain Mortar with Crusher — grinds crystals to a fine powder before loading.
• Spatula, Chattaway — handles small quantities of solid sample.
• Analogue Melting Point — a knob-controlled alternative with a magnifying eyepiece.
• Melting Point Apparatus, Digital — a digital model that tests three samples at once.

See more instruments in the Measuring category.

Frequently Asked Questions

How many samples can the Digital Melting Point Apparatus test at once?
The Digital Melting Point Apparatus takes 2 samples at a time. Running an unknown beside a reference compound, or two recrystallised fractions side by side, makes comparisons quicker and helps students judge purity from the melting behaviour.

What temperature range and accuracy does the Digital Melting Point Apparatus offer?
The Digital Melting Point Apparatus works from ambient temperature to 300 °C, with 1 °C resolution and an accuracy of ±1% of the displayed temperature. Readings come from a PT100 sensor and appear on a large three-digit LED display.

How does heating work on the Digital Melting Point Apparatus?
The Digital Melting Point Apparatus heats at 20 °C per minute to a selected plateau and holds there until you start the test. It then ramps at 2 °C per minute to the melt, giving time to observe each sample closely.

How is the Digital Melting Point Apparatus cleaned?
The viewing cover of the Digital Melting Point Apparatus is easily removed, giving access to the bulb and allowing cleaning. Take out used tubes once the block has cooled, and wipe away any spilled sample so it does not affect later readings.

What mains supply does the Digital Melting Point Apparatus need?
The mains supply for the Digital Melting Point Apparatus is not stated in our current listing. Tell us your laboratory voltage and frequency through the contact page, and we will confirm suitability before the quotation is issued.

Melting-Point Tubes (Product Code: SLE/ME/44) are thin-walled capillary tubes used to hold small powdered samples during melting point determination in chemistry, pharmacy and teaching laboratories. Each tube is 100 mm long and 1 mm in diameter, so it needs only a tiny amount of sample and lets heat pass quickly from the heating block to the solid. They are supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a lab consumables supplier for India and international markets.

Specifications

What Are Melting-Point Tubes Used For?

In the capillary method, a finely ground solid is packed into the closed end of a melting-point tube, the tube is placed in a melting point apparatus, and the temperature at which the solid starts and finishes melting is recorded. A pure compound melts over a narrow range, while impurities lower and broaden it, so these tubes are central to identifying organic compounds and checking the purity of products such as recrystallised samples in school and college chemistry lab equipment sets.

To fill a tube, press the open end into a small heap of dry, powdered sample, then tap or drop the tube, closed end down, so the solid settles into a short, tightly packed column. Use a fresh tube for every determination and wipe the outside clean before inserting it into the heating block.

What to Specify When Ordering

• Number of tubes required — the pack size is not listed here, so tell us your total quantity.
• Which melting point apparatus you use, so we can check the 1 mm diameter suits its sample holes.
• Whether one end should already be sealed, or whether you seal the tubes yourself.

Supplier

ScienceLab, the trading name of Jain Scientific Equipments Private Limited in Ambala, Haryana, supplies Melting-Point Tubes as a consumable for chemistry and pharmacy practicals. Because the tubes are used once and discarded, schools and colleges usually re-order them each term alongside their melting point apparatus and other consumables. Learn more on the ScienceLab company profile.

Related Measuring Equipment

Apparatus and tools used with melting-point tubes:

• Digital Melting Point Apparatus — a two-sample instrument with an LED temperature display.
• Analogue Melting Point — a knob-controlled unit with a magnifying eyepiece.
• Apparatus Melting Point — another block-heated option for teaching laboratories.
• Pestle And Mortar — for grinding samples to the fine powder the tubes need.

See the complete Measuring category for more laboratory instruments.

Frequently Asked Questions

What size are the Melting-Point Tubes?
The Melting-Point Tubes are thin-walled capillary tubes, 100 mm long and 1 mm in diameter. The narrow bore holds only a small amount of sample, which helps the solid heat evenly and makes the start and end of melting easier to see.

Are the Melting-Point Tubes sealed at one end?
This listing does not state whether the Melting-Point Tubes are supplied with one end sealed. Please confirm with us before ordering; tubes open at both ends are normally sealed at one end in a small flame before filling.

Which apparatus can the Melting-Point Tubes be used with?
The Melting-Point Tubes are intended for capillary melting point apparatus, such as the digital and analogue melting point units in our Measuring range. Check that the 1 mm tube diameter suits the sample holes of your apparatus before ordering.

Can the Melting-Point Tubes be reused?
No, the Melting-Point Tubes are normally used once, because the melted and re-solidified sample cannot easily be cleaned out of such a narrow bore. Dispose of used tubes safely in a sharps container.

How many Melting-Point Tubes come in a pack?
The pack size of the Melting-Point Tubes is not listed on this page. Tell us the total number of tubes you need through the contact page, and we will confirm the pack quantities we can supply in the quotation.
