The lamp operates on disposable alkaline batteries. With fresh alkaline cells, continuous operation lasts about 2.5–4 hours. If left on continuously, the batteries can drain in less than half a day. If the lamp is used for 15–30 seconds to check a TLC plate and then turned off, a single set of batteries can last weeks to months. Lamp brightness decreases as battery voltage falls. This product is a battery-powered field/bench model with no charging port or AC adapter. A plug-in or dedicated rechargeable version is not available. External NiMH AA batteries can be used, but their lower nominal voltage (1.2 V per cell) may reduce overall performance and runtime.

How can I determine the shelf life / expiration / retest date of this product?
1 answer-
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.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
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

Is this lamp suitable for a 8x8x0,1cm nylon membrane? It is needed for UV-crosslinking of RNA on the nylon membrane. Thank you
1 answer-
The dimensions of this lamp are 16.1 x 2.4 x 5.5 cm, so the area of an 8 x 8 x 0.1 cm nylon membrane would not be fully covered for completely even irradiation. This lamp was developed specifically for use in visualizing thin-layer chromatography plates. It cannot be guaranteed to supply the power necessary for RNA crosslinking. Use of the product for this purpose is outside the original scope of design and falls under the discretion of the customer.

Buongiorno, volevo chiederle se il prodotto "1.12537" sia solo la lampada UV oppure tutto l'apparato con anche "il sistema elettrico" che permette di accendere e mettere in funzione la lampada. Mi potrebbe aiutare a capire? La ringrazio
1 answer-
This is a whole electrical assembly with a UV lamp. It is mainly used for Thin Layer Chromatography analytical purposes.
