Built with sophisticated feature and functionality, Microlit Bottle Top Dispenser is a liquid handling instrument which has made dispensing reagents easy. For effective handling of the Bottle Top Dispensers there are a few points that have to be kept in mind. Read this presentation to know more.

1. 5 Things to remember
while using
Bottle Top Dispensers

2. Introduction
• A Bottle Top Dispenser (BTD) is a scientific apparatus that
helps in dispensing chemical reagents (acids, bases, alkalis,
etc).
• The process of dispensing manually poses multiple risks
like spilling of chemicals, inaccurate measurements and
even fatal lab accidents.
• In order to prevent such hazards and enhance lab safety,
Bottle Top Dispensers are one of the best dispensing
alternatives available to scientists. Manual dispensing poses multiple risks

4. Benefits of Bottle Top Dispensers
1. Accuracy & Precision:
Bottle Top Dispensers are known to offer approximately 0.5% to 0.6% accuracy. An added benefit is the narrow
delivery tube which makes dispensing into small-sized containers (like a test tube) convenient.
2. Safe & Easy to Use:
The use of Bottle Top Dispensers in a lab ensures safety as well as ease of use for scientists & researchers. Bottle
Top Dispensers provide a closed environment for reagents, preventing accidental spilling and reducing the risk of
exposing users to hazardous chemicals. The adapters which are generally provided with the dispensers as an
accessory, allow the dispenser to comfortably fit most laboratory reagent bottles.

3. Time Saving:
Bottle Top Dispensers are not only effective in safe dispensing but also enhance productivity by increasing the
pace of work. It could take hours to prepare multiple samples of the same quantity when reagents are being
poured by hand from the source container to the receiver container. However with Bottle Top Dispensers,
multiple samples can be prepared within a short span of time.
4. Chemical Saving:
Bottle Top Dispensers, by design, prevent wastage and accidental spilling of reagents. They are equipped with a
recirculation valve which prevents the loss of reagents during purging by redirecting them into the mounted
bottle, thus facilitating bubble-free dispensing. Other than this, if the recirculation valve is closed and the piston
is pressed down accidentally, the reagent will go back into the bottle rather than spilling out.

6. 5 Things to Remember While Using a Bottle Top
Dispenser
• It’s a prerequisite for every experiment to be error-free. Every reading has to be accurate to
produce the same result repeatedly.
• This is where Bottle Top Dispensers come into the picture.
They are a piece of sophisticated & safe scientific lab equipment for handling reagents. Certain
things that have to be kept in mind while using a Bottle Top Dispenser are mentioned in the
upcoming slides.

7. 1. The kind of reagent to be dispensed
• Scientists work with various kinds of reagents and every reagent has
its own properties. The highly aggressive ones can corrode the
apparatus that they are exposed to. In order to avoid this, make sure
that the components of Bottle Top Dispenser which come in contact
with the reagent/ chemical are made up of chemically inert material.
• Remember, corrosion is not just hazardous for the apparatus but also
for the users because in the unfortunate case of leakage, it can lead
to both chemical wastage and lab accidents. Therefore, before using
a Bottle Top Dispenser, ensure the kind of reagent you’re working
with and proceed accordingly.

8. • Any scientist working with Bottle Top Dispensers should make sure
that the size of the dispenser is apt and that it fits properly. This is
important because an ill-fitted dispenser can lead to spilling of the
reagents – a mishap that Bottle Top Dispensers are designed to
prevent!
• Thus, only when you take note of the fit, can the dispenser prevent
hazardous or fatal lab accidents and avoid wastage of reagents.

9. 3. Protective gear
• Before starting any experiment, even with a Bottle Top Dispenser,
take proper safety measures and wear the right protective gear.
• Wearing safety gloves and masks even while working with a Bottle
Top Dispenser is always encouraged because the more preventive
measures you take, the better it is.

10. 4. Ensure proper installation, calibration and
maintenance
● To ensure that a Bottle Top Dispenser works
efficiently, install it with proper care and follow the
instructions diligently.
● Upon installation, make sure that the Bottle Top
Dispenser is properly calibrated so that it can
facilitate reliable and consistent dispensing of
reagents.
● Bottle Top Dispensers can be used for a long time
but for that, you have to ensure its proper & timely
maintenance.

11. 5. Store in sterile conditions
• Bottle Top Dispensers which can be autoclaved directly on a bottle containing reagents eliminates the risk of the
reagent coming in contact with air.
• However, every Bottle Top Dispenser has an opening at its side or at the back which can lead to the introduction of
air into the device.
• Therefore, always store your Bottle Top Dispensers in a biosafety cabinet. Air can contaminate the reagent and
cause a safety hazard.

12. The benefits of a Bottle Top Dispenser are innumerable and Microlit is one of
its proud producers. We have introduced three models of this instrument in
the market –
• Microlit Scitus with Springless ValveTM
Technology – A simple,
cost-effective Bottle Top Dispenser that offers smooth and jam-free
functioning.
• Microlit Beatus with Recirculation Valve and Springless ValveTM
Technology – Prevents the loss of reagents during purging with
bubble-free dispensing and offers smooth and jam-free functioning.
• Microlit Ultimus with Patented Dual InletTM
Technology – Offers 4
modes of operation – rinsing, dilution, bottle refilling and dual liquid
dispensing- without dismounting the instrument from the reagent
bottle.

13. Conclusion
Bottle Top Dispensers are a blessing for labs. By reducing the manual dispensing of reagents from big
containers, they have saved a lot of time, reagents and also prevented fatal lab accidents. Such incredible
instruments can be used more effectively when the people working with them are careful and keep in mind the
points that have been discussed in this slideshare.
