Setting up a Bottle Top Dispenser

What is a Bottle Top Dispenser?

 A Bottle Top Dispenser (BTD) is a scientific apparatus that helps dispense chemical reagents (acids, bases, alkalis, etc.).

When a lab assistant carries out the procedure manually, they do so, not without multiple risks that come with it. Chemical spillage, inaccurate measurements, and even fatal lab accidents have always acted as speed bumps in laboratories.

To prevent such hazards and enhance lab safety, Bottle Top Dispensers are among the best dispensing alternatives available to scientists. With accurate fittings and thoughtful design, every bottle top dispenser prepared at Microlit is safe and easy to use.

Setting up a Bottle Top Dispenser

1. Checking the calibration report

  • Start by thoroughly going through the calibration report generated by the Bottle Top Dispenser.
  • The report must show the factory calibration process on the monitor with the listed serial number.
  • By examining the report, we can now estimate the instrument’s behaviour.

2. Choosing the right adapter

  • An adapter is provided that helps in mounting the dispenser. It’s attached to the reagent bottle.
  • Choosing the right size and material of the adapter plays a pivotal role in its administration.
  • Adapters made with polypropylene work for most applications.
  • ETFE/PTFE adapters are used for aggressive acids and solvents.
  • The available sizes are – 28 mm, 32 mm, 36 mm, 40 mm, and 45 mm.

3. Attaching the inlet tube or extension

  • The Telescoping tubes are adjusted to the varied bottle sizes.

4. Mounting the dispenser on the reagent bottle

  • After connecting the inlet tube to the dispenser, mount it on the reagent bottle and screw the dispenser tightly onto the bottle.

5. Purging the dispenser

  • It is crucial to remove the air (purge) from the dispenser.
  • Turn on the recirculation knob.
  • Run the dispenser a few times till the barrel is bubble-free.
  • Turn off the recirculation knob.
  • Run the dispenser to ensure bubble-free dispensing.

6. Setting the right volume

  • To start dispensing, the user should set the right volume that he/she needs to administer.
  • EasyKnobTM is a specially designed volume adjustment knob that allows 180° rotation for easy and effortless volume setting.

7. Dispensing

  • FlexiNozzleTM is an adjustable delivery nozzle. It offers a high degree of flexibility, facilitating easy dispensing in demanding laboratory conditions.

Microlit LentusTM with Recirculation Valve and Springless ValveTM Technology

MICROLIT LENTUS™ Bottle Top Dispenser (BTD) is a high precision liquid handling instrument. This bottle top dispenser is used to dispense Hydrofluoric Acid, high-purity media, acids and bases, and Trace Analysis. It has been engineered with carefully selected and tested materials for use with Hydrofluoric Acid (HF).

Key Features of a Microlit Bottle Top Dispenser

Autoclaving – Microlit Bottle Top Dispensers are fully autoclavable at 121 °C and 15 psi for 10 – 15 minutes.

Calibration – Microlit provides the user with a calibration tool inside the package for quick in-lab calibration.

Cleaning – For effective results, cleaning the dispenser is vital. Pure chemicals used for analytical purposes are used for this cleaning procedure.

Precautions and Safety Measures

Before disassembling the device, it is vital to get rid of the residues of the liquid. Here, rinsing the dispenser with demineralized water a couple of times will do the job. Afterwards, fresh water and a mild detergent, and a soft brush can be used to clean the piston and cylinder. Pipe cleaners can be used to clean the tubes.

Precision and Accuracy – Our ultimate purpose

Following the steps mentioned above will enable the users to carry out the dispensing process without any hassle and ensure that the study results are accurate.
