Booking rules

In addition to the General Rules, the following specific booking rules apply.

...

• Always remove latex or nitrile gloves before touching the keyboard, mouse, microscope focus and buttons to prevent contamination with biological material and immersion oil
• Always keep immersion oil bottles in the petri dishes provided. This is to stop oil getting everywhere. Do not put anything else in the dishes
• Always keep the Cargille Type 37 oil and Zeiss Immersol W in the weighing boat inside the chamber so they are at 37°C when the chamber is on
• Always keep the Cargille Type HF oil in the tray outside of the chamber. Type HF oil is optimised for use at 23°C
• Always keep stage adapters and inserts inside the chamber so they stay at the same temperature as the microscope
• The large adapters that screw into the stage MUST be kept on the right-hand side of the chamber. This is to stop the stage hitting the adapter when it calibrates
• The small inserts that fit into the adapters should be kept on the left of the chamber, out of the way of the oil, humidifier and other accessories
• The CO2 cover does not need to be kept in the chamber
• You MUST take care not to drop the thumbscrews when changing the stage adapter; they could get caught in the microscope mechanism. If you lose a thumbscrew you must report it to the following email address immediately and say whether it was dropped inside or outside the chamber: lmcblmcb-lm-help@ucl.ac.uk
• You MUST make sure that the condenser is clear of the stage and that the objective lens nose piece is in the Escape position before calibrating the stage. If this is not done the stage will hit the condenser or an objective lens when calibrating
• If you are imaging a specimen overnight or for longer you MUST turn off the Exfo X-Cite lamp. It isn’t needed for imaging and leaving it on shortens the life of the bulb unnecessarily
• You must NEVER leave the microscope stand with the objective lens nose piece in the Escape position. This is because the next user will not be able to focus with the Escape button pressed. Also, if they work out what has happened and press the Refocus button the objective lens may go straight through their sample
• You must wipe all the lenses you used after you’ve finished your session.
• Only use the Whatman 105 lens cleaning tissue to wipe lenses
• Always clean up any spilt medium. The salts in media react with the metal of the microscope and can cause serious damage
• You MUST dispose of your specimens according to the LMCB Code of Practice for Laboratory Workers. Gloves and tissues should be discarded in the yellow clinical waste bag. Sharps and small biological specimens (e.g. Lab-Teks and 35 mm dishes) may be placed in the sharps bin provided, but any larger biological specimens must be taken away and treated overnight with a suitable disinfectant before disposal.
