How is Microlit E-Burette better than a Digital Burette?

What is a Burette?

A burette is a laboratory equipment commonly used to carry out a titration. A titration is a technique where a solution of a known concentration (titrant) is used to determine the unknown concentration of a second solution (analyte). A visual indicator usually signals the completion or the end-point of the experiment.

Two types of burettes that are commonly available and widely used include glass burettes and digital burettes. Before we discuss how electronic burettes or E-Burettes are better than both of these, let’s have a look at all, one by one.

Difference between Digital Burettes and E-Burettes

What is a Digital Burette?

A digital burette is a relatively high-cost equipment with more sophisticated features than a glass burette. It can be connected to a computer and its titration readings can be saved on the same.

In digital burettes, a high precision piston is used to deliver aliquots. They are to be used as per the nature of the solution to be titrated; whether or not it has a corrosive effect on glass or PTFE. The barrel and plunger of a digital buret are typically constructed from glass, though plastic barrels and plungers may be used for solutions of alkali, which may corrode glass.

While titrating, the barrel of a digital burette is held in a fixed position and the plunger is moved incrementally in one direction manually by turning the knob. The volume gets displayed on a digital screen.

What is an E-Burette?

An electronic burette or E-Burette, like the Microlit E-Burette, is an advanced burette designed keeping ergonomics and intuitive handling in mind. It offers sophisticated features and functionality like, motor controlled piston movement, a touch screen enabled Control Panel with a graphical user interface (GUI) and calibrated pre-set speeds to perform highly accurate titrations.

The accuracy offered by the Microlit E-Burette is way higher than that offered by glass burettes. Also, there is a negligible chance of human error due to automation of most of the work unlike in the case of glass or digital burettes.

Its motor controlled piston movement eliminates the limitations of digital burettes and glass burettes that dispense manually. The user-friendly touchscreen guides quick and accurate titrations and displays numeric data up to the second decimal. It also offers the user a choice to work at pre-set speeds during titrations including dropwise dispensing, which helps in achieving the endpoint with high accuracy. It is equipped with an enhanced dropwise dispensing feature called “One-Touch, One-Drop”. This feature enables users to dispense reagents to the minutest volume.

Exclusive and advanced design features of the Microlit E-Burette

3 Pre-set Speeds for Dispensing

It comes with 3 individually calibrated Pre-set Speeds, including dropwise dispensing.

Motor Controlled Piston Movement

In conventional Digital Burettes, dispensing is done ‘manually’ with the help of a rotating wheel, whose speed of rotation is not fixed and varies from user to user. Any abrupt changes in the speed may result in inaccurate and imprecise results.

The Motor Controlled Piston Movement of Microlit E-Burette, at 3 Pre-set Speeds, rules out the effort invested in manual wheel operation and hence, any inconsistencies arising due to the variations in its speed.

Assured Quality with ISO 8655 Conformation and GLP Compliance

It conforms to ISO 8655 standards and is GLP compliant. Each model is individually calibrated and supplied with a calibration certificate placed inside the product package. The instrument can also be easily calibrated electronically within a laboratory, without the help of an external calibration tool.


Save Results on the Go

The E-Burette can store up to 20 results in its memory. It also offers the option to connect to a computer and save the readings on software for future reference.
