Volumetric Flask, Class A, Light-Shielding

Product and ordering information for Volumetric Flask, Class A, Light-Shielding.  Tinted PMP volumetric flasks are an excellent choice for light-sensitive materials. Superior opacity compared with amber glass. Light-weight and break resistant.

Catalog #: N/A Category:
   

Description

Tinted volumetric flasks of polymethylpentene (PMP) offer superior opacity to ultraviolet light, as well as much of the visible spectrum, compared with amber glass. They are also light weight and offer superior break resistance. An excellent choice for measurement of light-sensitive materials.

Flasks are available in sizes from 10mL to 1000mL and are supplied with tinted PP screw caps. They offer accuracy to Class A standards per DIN EN ISO 1042, even after autoclaving at temperatures up to 121°C (to preserve markings, cleaning at no higher than 60°C is recommended). Flasks may also be sterilized with formalin or ethanol, or by β-radiation, and are microwavable. Excellent resistance to acids, alkalis and alcohols at room temperature, and good-to-limited (short term exposure) resistance to aliphatic hydrocarbons, aldehydes, ketones and esters. They are not suitable for use with aromatic or halogenated hydrocarbons, ethers, oxidizing acids or oxidizing reagents.

Each flask is individually calibrated “to-contain” (‘In’) at a reference temperature of 20°C, individually ring-marked, for accuracy, imprinted with a lot-number, and shipped with a lot certificate. The high contrast ring-mark ensures an accurate reading of the meniscus.

FAQs

Are the graduations on your volumetric plasticware molded on the inside, outside, or simply screen printed?

None of the graduations are molded on the interior. They would be very difficult to mold in that way, and would interfere with the accuracy. Exterior molding also allows for a better grip on the item. However, it does differ by product, specifically:

  • Graduated cylinders: All models have molded graduations. Some have screened overprint.
  • Volumetric flasks: All models have a scored graduation, with coloring added.
  • Erlenmeyer flasks: All models have screen printed graduations.
  • Griffin Beakers: Most models have molded graduations (with the exception cat. no. V110204-V111004, ETFE Griffin beakers, and some small volume sizes). Some have screened overprint.
  • Graduated pitchers: All models, with the exception of the nesting models, have molded graduations. Some have screened overprint. Nesting models have printed graduations.

How should I clean my volumetric plasticware?

Polyolefins, such as PP and PMP, as well as fluoroplastics (ETFE), have water-repellent surfaces that are very durable and easy to clean. For cleaning, depending on the level of contamination, commercially available neutral or alkaline detergents (i.e. Mucasol) can be used. Please note that no scrubbing agents or scouring pads should be used for labware made from plastics.
Plastic labware can be cleaned and dried in a laboratory diswasher, noting the temperature limits of the individual products. Due to their light weight, securing the labware with washing nets is recommended; and plastic-coated wire baskets will better protect against scratching.
Plastic labware can also be cleaned in an ultrasonic bath. However, direct contact with the acoustic membrane should be avoided.

Can I autoclave my volumetric plasticware?

The product description and/or specifications state whether or not the product can be autoclaved (note the temperature limits!). If the product is autoclavable, the recommended protocol is 20 minutes at 121°C (2 bar), according to DIN EN 285.
Prior to autoclaving plastic labware, ensure that no residual contamination remains on the item. Otherwise, the residual contamination will bake on solidly during the autoclaving process. Even substances that have no effect on the plastic at room temperature can have negative effects on the plastic during the autoclaving process, including persistant clouding. Additionally, microorganisms might not be killed effectively if they are protected by the residual contamination.

Notes on autoclaving:
  • Containers with screw tops or stoppers must be open during autoclaving to allow for pressure equalization - Autoclaving of a closed container will lead to the deformation or destruction of the container.
  • Plastic labware should be stood upright on a level surface during autoclaving to avoid shape deformation - Plastic labware should NOT be laid on its side during autoclaving.
  • No mechanical stresses should be present during autoclaving - For example, do not stack items.
  • Do not autoclave any container that contains residual contamination or even rinsing agent.
  • Some transparent plastics can absorb minute quantities of steam, which can lead to reversible clouding. This clouding disappears upon drying.
