Why is Safe Handling and Care of Laboratory Analytical Instruments essential?
Always follow safety instructions before handling laboratory instruments

Sophisticated analytical instruments cost a fortune and therefore require careful handling and care. This ensures consistency of results and low maintenance costs. In addition to smooth operation it is equally important that such instruments do not pose safety hazards to the operator and others in the laboratory.


Sophisticated instruments comprise of highly sensitive and delicate optical and electronic components requiring recommended handling care right from stage of transportation to user location.

Apart from breakages sensitive optical instruments can lose proper alignment which can take several hours to restore. For this reason all such equipment should be carefully placed on wooden or plastic frames and secured using nuts. The frames should be provided with caster wheels and packed in wooden or hard cardboard boxes. Free space inside such packings should be filled with thermocol sheets to prevent movement during handling and transportation.

On reaching the user site after inspection for any physical damage during transportation the instrument should be carefully removed from the packing and placed on a sturdy bench.


In the first place the instrument should be installed in the recommended environmental conditions such as temperature, humidity, air conditioning, etc. Adequate power and operational utilities should be provided. Power surges and voltage fluctuations contribute to component failures and expensive breakdowns. It is essential to maintain uninterrupted power supply which is free from spikes. Electrical points should be of specified capacity with proper earthing. The points should never be overloaded by using multipoint sockets.


Instruments can pose different hazards if safety guidelines are ignored. Some common hazards are:

  • Electrical shocks through contact with components or surfaces bearing high voltage or current. Always look for electrical safety warning signs before touching any component or surface when the instrument is functional
  • Burns can result from hot surfaces as it is not possible to gauge the temperature of a surface. Be on the lookout for warning signs and give sufficient time even after instrument is switched off
  • Eye damage can result from looking directly into light sources such as deuterium lamps, plasmas and flames. Always use safety goggles and ensure that you view through safety shields.
  • Strong magnetic fields are present in the vicinity of magnets used for high resolution NMR spectrometers. It is advisable that persons with implants or pacemakers avoid working on such systems.
  • Radiation exposure can result from working on instruments equipped with radioactive isotopes sources. Adequate protection should be provided and constant monitoring of workers for radioactive exposure should be in place.
  • Certain instruments develop high fluid pressures during operation. Adequate safety precautions and measures should be taken when operating such instruments.

Analytical instruments are capable of providing high-quality data for years together provided handling care is taken and safety concerns are not overlooked.

  1. Hello Sir,

    Few query from you.

    Can we keep sophisticated instruments i.e. HPLC, ICP, auto titrators continuose running 24 hrs/ 365 days. Is it advisable?

    How we can reduce consumables cost by recycling it. As far as I am thinking ppb level consumables of one time use but we can recycle after cleaning ppm to % level any analyticals consumables.

    Thank you in advance for your feedback.

    Thanks & regards,

    1. No one will advise running an instrument 24 hrs continuously for 365 days as you require periodic maintenance for upkeep and reliability of results.You are right when you say that for ppb level determinations consumables should be put to single use
      and discarded.However ,even for higher concentration analysis it is recommended to validate the freedom of vials and other consumables from contamination prior to reuse as per recommended procedures.
