詳細
Visiprep™固相抽出バキュームマニホールドおよび付属品は、固相抽出による実験用液体サンプルの調製および精製を自動化します。真空ポンプと併用することで、Visiprep™マニホールドは、12本または24本までの試料を同時に抽出することができ、液液抽出法と比較して、サンプル処理量を大幅に増加させると同時に、サンプル調製のハンズオンタイムを削減します。Visiprep™バキュームマニホールドは、真空開放バルブと自立型カバーを備えており、精密な流量調節と安全で容易な使用を提供します。メルクの流量調節弁は、カバー内蔵の個々のねじ式バルブを回転することで、各チューブを通る流量の精密な操作を可能にします。メルクの最近最適化された標準マニホールドは、PFAS検査領域におけるSPECIAL法に適しています。PFAS（PTFEなど）を含有するすべての重要な部品は、超高分子量ポリエチレン（UHMWPE）やステンレス鋼（ニードルガイド）などのPFASフリーの代替品に置き換えられています。これにより、SPEプロセス中のPFASバックグラウンドの混入が低く抑えられます。ガラス容器は強力な溶媒にばく露しても、溶解、曇り、変色を起こしません。マニホールドラックには、オートサンプラー用もしくは小型シンチレーション用バイアル、10 mmもしくは16 mm試験管、または1、2、5もしくは10 mLメスフラスコが収容されます。オプションのプレートは、12ポートモデルで最大10本の20 mLシンチレーションバイアルが入ります。 真空開放バルブは、真空レベルの調節を改善し、より確実なバルブの閉鎖を保証します。このねじ式バルブには、超高分子量ポリエチレン製コーン形シールが装着されています（PTFEフリーになりました）。ねじを締めると完全な密封が確保され、バルブで漏れは起こりません。ねじを緩めると密封が破られ、直ちに真空を開放して抽出を停止したりマニホールドカバーを持ち上げたりすることが可能になります。4本ある2インチの脚でカバーを作業面に立てて、SPEチューブを直立位置に保つことができます。これにより、溶媒ガイドが作業面に置かれて損傷したり汚染されたりするのが防がれます。 マニホールド上の乾燥用アタッチメントは別売りです。数分間で取り付け可能で、どのような不活性ガスも使用できます。また、乾燥用アタッチメントは回収されたサンプルの濃縮にも便利です。各チューブへのガス流は個別に調節することができます。

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

What additional items are required to utilize Visiprep Manifold 57030-U?
1 回答-
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.役に立ちましたか？

What leads to the vacuum gauge needle on the Visiprep SPE Manifold to bounce back and forth instead of being steady?
1 回答-
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.役に立ちましたか？
