Instrument used in measuring specific gravity / relative density of liquids.
Hydrometers are used in different states, such as a lactometer for measuring the density (creaminess) of milk, saccharometer for measuring the density of sugar in a liquid, or an alcoholmeter for measuring higher levels of alcohol in
The demonstration method is the ratio between density of the liquid and the density of water.
The hydrometer is made up of glass material, cylindrical stem and a bulb contains mercury/ lead shot to make it float upwards.
Useful for the demonstration of characteristics associated with high voltage phenomena such as with Geissler tubes, spectrum analysis tubes.
This traditional induction coil is capable of producing a spark length of up to 30mm with an input of 6-8V DC and is therefore ideal for use with vacuum tubes, eudiometers, etc.
A fully adjustable trembler system is incorporated and spark suppression capacitors are housed in the base Rhumkorff commentator allows primary current to be both reversed and switched ON/OFF with make-and-break point.
A pair of pointed electrodes is supplied with the instrument, the pointed electrodes having an insulating handle for adjustment of the spark gap. Low voltage input is provided via a pair of baseboard mounted color coded 4mm sockets.
This device is used to support lamps and connect them through electric circuit.
The device basically holds the light bulbs and develops electric connection to provide bulbs with powers.
These E27 Ceramic bulb holders accepts any lamp with an E27 screw fitting, including the James compact reptile lamps, as well as other types such as ceramic heat lamps.
The ceramic material is resistant to high UV and heat levels. Mounted in Ceramic bulb holders that fixes to the vivarium roof or wall and which can be angled to direct the focus of the lamp.
Lamp holders are used with most light sources for incandescent, fluorescent, and compact fluorescent lamps (CFL).
