If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

Características y beneficios
- Válvulas de tipo tornillo patentadas dentro de cada puerto de SPE para un control de flujo preciso
- El cuenco de vidrio no se disolverá, empañará ni cambiará de color cuando se exponga a disolventes
- Las patas de la tapa permiten al usuario apoyarla fácilmente sobre la superficie de trabajo cuando la quite de colector
- El manómetro y la válvula de purga de tornillo resistentes al disolvente ofrecen un mejor control del precinto y del vacío. La válvula ocupa 1/4″ del tubo de vacío.
- En la gradilla de recipientes de recogida de PP pueden colocarse viales de automuestreador; viales de centelleo pequeños (D.E. recomendado, 22,75 mm); tubos de ensayo de 10 y 16 mm; y matraces aforados de 1, 2, 5 y 10 ml. Para los modelos de 12 puertos, se dispone de una placa opcional para viales de centelleo de 20 ml.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 respuesta-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

Following are the dimensions for the valve placements.
Visiprep 12 Port, Product numbers 57030-U & 57044
1 1/8" (1.14") Between valves (center to center)
1 5/8" Between rows (center to center)Visiprep 24 Port, Product numbers 57250-U & 57265
7/8" (0.875") Between valves (center to center)
1 3/8" Between rows (center to center)All ports on the 12 and 24 vacuum manifolds can only be used simultaneously with 1, 3, and 6mL tubes. In order to use all ports of the manifold with 12, 20, or 60 mL SPE tubes, Long Stem Flow Control Valves are required – see product 57048.

What leads to the vacuum gauge needle on the Visiprep SPE Manifold to bounce back and forth instead of being steady?
1 respuesta-
The fluctuation of the vacuum gauge needle usually indicates a faulty diaphragm, necessitating the replacement of the entire gauge. Part number 57035-U is the Vacuum Gauge with Bleed Valve for both the 12-Port and 24-Port Visiprep SPE Manifolds.
For the Visiprep Vacuum Gauge, the gasket is an essential matched part and, as such, cannot be replaced independently of the other components.¿Le ha resultado útil?

What additional items are required to utilize Visiprep Manifold 57030-U?
1 respuesta-
To operate both the standard Visiprep SPE Manifolds (57030-U and 57044) and the Visiprep DL Manifolds (57265 and 57250-U), you will need a vacuum pump and a Waste Trap Kit (57120-U). The waste trap should be installed between the manifold and pump to ensure that the waste going into the glass basin is pulled through the front gage and out into the waste trap.
Other necessary items include:
• SPE tube of choice
• Vials, test tubes, or other collection vessels that fit the polypropylene collection vessel racks, accommodating autosampler vials, small scintillation vials, 10 and 16 mm test tubes, and 1, 2, 5, and 10-mL volumetric flasks. An optional plate for 20 mL scintillation vials is available for 24-port models.¿Le ha resultado útil?
