The SC601 cup is mostly flat on the bottom. It does stand up on its own but the bottom of the cup has a small dimple that is concave up into the bottom of the cup. The SC475 vessel is completely flat on the bottom with no dimple at all. It is a screw cap instead of a snap cap.

The SC415 and the SC414 are the same sample vials, the SC415 come with caps and the SC414 do not. Certificates of analysis are included with these vials showing metals background.

Lot #s for the various parts molded here at Environmental Express are based on the partent resin used for those parts. Those parts that use the same type of plastic are often molded with the same lot of resin material.

Our SC475 tube is 39.45mm diameter at the bottom and 30.25mm diameter at the top, just below the screw threads. The height of the cup is 106mm.

If you are using a separate vessel to monitor temperature I would attempt to make it as closely related to your samples as possible so use the same volume as your samples.

The SC475 cups are 34.5mm x 109mm. We also offer part # SC601 which is the snap cap cup specific to the CPI block.

Pressure caps are not available for this vessel.

PFA (Teflon) has a maximum, continuous temperature of 260 deg C.

The cap is plastic. It is not designed to pop off at any given temperature--it is merely a cap to contain the liquid in the vessel.

There is no threading to this cup--it has a beaded lip to it and could potentially be stoppered. The cup is made of borosilicate glass.

By definition, plastic vessels can not be Class A volumetric devices--only glass vessels can. While the sample cups meet the Class A requirements of a graduated cylinder they are considered to be Class B because they are made of plastic.

The SC490 cups are made of polypropylene and have a temperature rating of up to 130 deg C so as long as the temperature is below this the cups will be fine.

18\" wide X 19.75\" deep X 18\" tall.

The maximum temperature polypropylene will withstand is 130 deg C before it melts. The longer the tubes are exposed to high temperature the more brittle the plastic will become. Typical digestion times, following US EPA methods, is around 6 or 7 hours for a maximum. \r\nThese methods also typically use concentrated nitric, sulfuric, and hydrochloric acids though they are added to water samples. Small amounts of these may also be added to soil samples (around 1g of soil) and the polypropylene cups have held up well in those types of digestions. Hydrofluoric acid at room temperature is fine with polypropylene but may cause issues at elevated temperatures.

We have Flipmate devices available for both our 50mL vessels and our 125mL vessels. Unfortunately we do not have a larger vessel that will accept the Flipmate.

Yes--you can purchase a 500pk of green caps only as part # SC475-C or white caps only as part# SC475-CW.
