Free your tired hands with lower cost

As we all know, sample vials are in high demand, and throwing them away after use will make people feel wasteful. Many times, people choose to clean the sample bottle in order to save costs, but does cleaning the bottle really save costs?

First of all, Welch will give you an example of cleaning a vial, and we will analyze it again.

Cleaning with alcohol

  • Rinse the bottle several times with clean water
  • First use alcohol ultrasonic cleaning 2 times for 15-20 minutes each time
  • Ultrasonic cleaning with pure water for 2 times, 15-20 minutes each time
  • Dry at high temperature, be careful not to exceed 110°C, it may cause damage to the sample vial

After reading the above example, let the Welch financial expert help you to see whether washing the bottle saves money or not.

In fact, the biggest problem is the consumption of detergent, and it also consumes manpower. If you just look at the money I saved by washing a lot of bottles and ignore the money and labor of the detergent used, you may inadvertently lose a lot. Moreover, what we can basically wash is the bottle itself, and the cover pad cannot be cleaned. The price of the bottle itself is not expensive, and the cleaning cost is not necessarily much lower than the price of the bottle itself.

Here’s to Welch’s Doprah® range of ultra-affordable vials, which are affordable, quality-assured, and low-cost. We can change the bottle instead of washing the bottle to save you manpower and financial expenses! There are also separate cover pads and inner tubes for additional matching.
