主要功能:
ez-gSEAL壓力控制器可輕松實(shí)現(xiàn)膜片鉗。復(fù)雜的膜片鉗實(shí)驗(yàn)變得像點(diǎn)擊幾下按鈕一樣簡(jiǎn)單。單擊**個(gè)按鈕設(shè)置正壓,**個(gè)按鈕設(shè)置負(fù)壓以設(shè)置封接,第三個(gè)按鈕設(shè)置保壓。通過單擊一個(gè)按鈕,您可以應(yīng)用脈沖進(jìn)入細(xì)胞。
ez-gSEAL 100B壓力控制器主要用于膜片鉗自動(dòng)封接,也可用于其他應(yīng)用。使用ez-gSEAL壓力控制器,細(xì)胞封接就像點(diǎn)擊一個(gè)按鈕一樣簡(jiǎn)單。您可以將它與我們的ezPATCH 100A智能機(jī)械手,PatchMAX 100A自動(dòng)封接膜片鉗系統(tǒng),ChannelMAX 100A Mini自動(dòng)雙鉗系統(tǒng)或ChannelMAX 100A Twin自動(dòng)四鉗位系統(tǒng)一起使用,用于全自動(dòng)膜片鉗實(shí)驗(yàn),或?qū)⑵溆米鳘?dú)立產(chǎn)品操作。可以使用控制器來吸食**或研究拉伸通道。軟件控制的壓力控制器配有泵,因此不需要空氣罐。
與之前的型號(hào)ez-gSEAL 100A壓力控制器,100B有許多改進(jìn):泵功率更大,使用壽命更長(zhǎng),設(shè)備內(nèi)的氣流得到改善,性能更佳,并配有壓力表幫助用戶確定用于制作密封件和闖入的壓力。
軟件控制:
ez-gSEAL控制軟件:NBSController控制壓力應(yīng)用并測(cè)量壓力。 常用的壓力可以預(yù)先設(shè)定,因此用戶可以點(diǎn)擊幾個(gè)按鈕進(jìn)行密封和破膜。
新!iPod Touch Control!
ez-gSEAL壓力控制器可由iPod Touch,iPhone或iPAD控制。 iPod Touch通過WiFi連接到服務(wù)器軟件NBSController,因此您可以使用iPod Touch作為遙控器來控制設(shè)備的設(shè)備。
與傳統(tǒng)的密封方法相比,使用ez-gSEAL壓力控制器有許多優(yōu)點(diǎn):
使用ez-gSEAL壓力控制器,可以在實(shí)驗(yàn)期間設(shè)置非常小的壓力,以使封接持續(xù)很長(zhǎng)時(shí)間。
膜片鉗實(shí)驗(yàn)變得**且可重復(fù)。當(dāng)您使用注射器或口腔式吸入細(xì)胞時(shí),通常很難控制壓力。使用ez-gSEAL壓力控制器時(shí),您可以定義吸入壓力和破膜持續(xù)時(shí)間。結(jié)果一致且可靠。在破膜后,膜很難重新封接,但如果發(fā)生這種情況,可以在不接觸微操的情況下施加更多的吸力。
它簡(jiǎn)單而無壓力。無需親自控制壓力,只需點(diǎn)擊幾個(gè)按鈕即可制作封接和破膜,提高工作效率。使用ez-gSEAL,只要記錄密封參數(shù),就可以輕松達(dá)到正常的密封成功率。成功率高。
自動(dòng)密封算法類似于PatchXpress®自動(dòng)膜片鉗系統(tǒng)中使用的算法。 PatchXpress用戶可以使用它在顯微鏡下測(cè)試其密封參數(shù),以便更容易地解決問題并降低成本。

Figure 1 Recording obtained at the Marine Biological Laboratory using the ez-gSEAL 100A pressure controller. LNV clock neurons in female Drosophila were used for electrophysiological recordings. A 6-7 micrometer diameter pipette filled with protease XIV was first used to digest the tissue above the clock neurons. The pressure setting for applying the protease XIV was 20 - 30 mmHg. When making the seal, 40 mmHg pressure was applied during the time the patch pipette (polished. Resistance ~ 17 MOhms) approached the neuron, and then -20 mmHg suction was applied to make the seal. The breaking-in pressure for this cell was -200 to -250 mmHg for 0.5 s. The holding pressure was _ 1 mmHg to keep the seal stable during the recording. This recording was obtained 3.5 hours after making the seal, and the cell was still healthy.

Figure 3 Sample AMPAR-and NMDAR-mediated current recorded from VTA DA neuron of p80 and older mouse. When making the seal, 50 mmHg pressure was applied during the time the patch pipette (Resistance ~ 2 MOhms) approached the neuron, and then -20 to -40 mmHg suction was applied to make the seal. The breaking-in pressure for this cell was -150 for 0.5 s.
