250ml clear borosilicate bottle
Forget about old bottles and cork caps! Use modern lab bottles to help preserve your chemicals. These bottles are more resistant to impacts and temperature changes than regular glass bottles; they also have airtight caps.
Alcohol lamps are used to dry and varnish wet plates.
20ml syringe.
The syringes are ideal for measuring small amounts of liquids accurately without the use of pipettes, which are much more expensive. For example, to replenish ether and alcohol in the excess collodion to return it to the original proportions of the mixture.
As with the other bottles, funnels, etc. involved in the process, it is essential to use them for a single chemical to avoid cross-contamination.
Precision hydrometer calibrated for specific densities between 1,000 g/cm3 and 1,100 g/cm3
Silver nitrate baths used in the wet plate process are a 9% silver nitrate solution in distilled water. That means 90g of silver nitrate dissolved in one liter of distilled water. Once we prepare this mix, there is only one way to find out how much silver nitrate there is in the bath: we need to measure the specific density of the solution with a hydrometer.
A 9% silver nitrate bath has a specific density of 1,067g/cm3. If our bath has a lower density we will have to add silver nitrate to the mix
