What to confirm before you order

Specification to confirm	Why it matters
Published dimensions	Dimensions are stated for some apparatus and not others. Where the item must fit a bench, stand or existing setup, ask for overall size in writing.
Materials of construction	Copper, brass, aluminium, borosilicate glass, nichrome, bakelite and wood are stated on some items. Material affects thermal and electrical behaviour, so confirm it where the experiment depends on it.
Accessories included	Several items are supplied with rods, weights, cords or test pieces. Confirm exactly what is in the box and what must be bought separately.
Consumables and services required	Some apparatus needs a steam supply, a spirit furnace, a water supply or a power source. Confirm what the laboratory must provide.
Calibration and scale	Where an instrument carries a scale, confirm the range, the smallest division and whether any calibration certificate is supplied.
Spares	Confirm availability of replacement glassware, heating elements, rods and cords, with part numbers.
Export packing	Confirm carton dimensions, gross weight and packing method, particularly for glass apparatus.

Who buys this range

Frequently asked questions

What electrical apparatus is published in this range?
Eleven items: Hoffman voltameter, junior circuit board, dial-type decade resistance box, potentiometer with pencil jockey, pencil jockey, meter bridge or Wheatstone bridge, plug-type post office box, two rheostats (nichrome groove type and constantine or eureka wire), plug-type resistance box and a clinostat.

What is the difference between the two rheostats?
One is published as a groove-type wound with nichrome wire on an aluminium former with brass fittings; the other is published as wound with constantine, also called eureka, wire with aluminium, brass and bakelite parts. Resistance range and current rating are not published and should be confirmed in writing.

What resistance values do the boxes cover?
The catalogue does not publish the resistance values, steps or tolerance for the decade resistance box, plug-type resistance box or post office box. Ask for the full value table and tolerance before ordering, since these determine what experiments the box supports.

Is the meter bridge supplied with a jockey?
The meter bridge is published as supplied with a pencil jockey, and the pencil jockey is also listed separately as a replacement item.

Where is this apparatus manufactured?
It is manufactured by Ambala Science Lab in Ambala, Haryana, India. Ambala Science Lab has operated since 2010 as a manufacturer and exporter of laboratory and educational equipment.

Can electrical apparatus be supplied against a government tender?
Yes. Send the tender annex or bill of quantities with your enquiry, including required resistance ranges and ratings, so the quotation matches the specification line by line.
