Product Description:

Measuring cylinder is an elongated glass cylinder, due to the cylinder body elongated, smaller than the same volume of the liquid level of the measuring cup, its capacity accuracy than the relative accuracy of the measuring cup, Jane the bottom of a wide-rimmed base, can be maintained at a tilt of 30 ° in the case of not pouring, the cylinder of the upper mouth of the production of pouring out the mouth, easy to pour out of the liquid. With stopper measuring cylinder in addition to the basic shape with the cylinder, the upper mouth of the cylinder does not have a pouring mouth, but made of contracted bottle mouth, and has a frosted glass stopper.

Product Features:

1,Transparent, clear scale.
2,Small expansion coefficient, small measurement error.
3,Stable nature of glass, and other substances generally do not react.
4,Easy to clean.

why choose us:

1. High precision: laboratory glass measuring cylinders have a high precision scale, which can accurately measure the volume of liquid.
2. High Transparency: The high transparency of the glass measuring cylinder allows the operator to clearly observe the volume of the liquid.
3. high temperature resistance: laboratory glass measuring cylinders can withstand a certain high temperature environment, so there will be no problem to use them in a high temperature environment.
4. Acid and alkali corrosion resistance: laboratory glass measuring cylinders can withstand common acid and alkali solutions, so the accuracy will not be affected by corrosion in the process of use.

packing and shipping:

We can use strong exporting boxes. It can avoid Lab Glass Measuring Cylinder with Graduation broken.

We can offer free measuring cylinder with glass stopper samples for checking quality. Clients need pay express freight charges, when you place orders, we will deduct the sample freight. Sample delivery time is about 1-3 days.

Large cargo delivery time based on order quantities. Usually it need 20-25 working days.

instruction for use:

When the amount injected is slightly less than the required amount (about 1mL difference), the cylinder should be placed horizontally squarely on the tabletop and a rubber-tipped burette should be used instead to add the required amount drop by drop.

Observe their ranges and divisions before using a measuring cylinder. The larger the cylinder and the thicker the diameter of the tube, the less accurate it is, and the greater the reading error caused by line-of-sight deviation.

When looking at the volume of the cylinder is to look at the center of the liquid surface, the line of sight when looking up the line of sight diagonally up the intersection of the line of sight and the wall of the cylinder under the liquid surface, so the read data is low, the actual value is high.
