詳細(xì)描述
Beckman JLA-16.250、JA-14同屬最大容量6×250mL角轉(zhuǎn)頭,適用于Avanti J-26S XP、Avanti JXN-30、Avanti JXN-26和Avanti J-E立式大容量低溫高速離心機(jī)(Avanti J-E高效離心機(jī)上使用最高轉(zhuǎn)速為14000 rpm)。
JLA-16.250屬于新型輕質(zhì)角轉(zhuǎn)頭(轉(zhuǎn)頭自身空重10.3 kg),上樣、轉(zhuǎn)頭密封和轉(zhuǎn)頭清理清潔操作更輕便。
角轉(zhuǎn)頭分為普通單鎖蓋型(Single Lock Lid)和雙重鎖蓋型生物安全型Biosafety Lid)兩款。
雙重鎖定轉(zhuǎn)頭蓋(Dual Locking Rotor Lid)為氣密性生物安全轉(zhuǎn)頭。轉(zhuǎn)頭蓋為雙旋鈕設(shè)計:一個圓形中心旋鈕用于把轉(zhuǎn)頭安裝固定在驅(qū)動軸上,一個梅花形旋鈕用于把轉(zhuǎn)頭蓋與轉(zhuǎn)頭密封。操作時,先將蓋子蓋住轉(zhuǎn)頭,順時針旋轉(zhuǎn)梅花形旋鈕至擰緊,確保轉(zhuǎn)頭密封;再將轉(zhuǎn)頭放到離心機(jī)上,順時針旋轉(zhuǎn)中心旋鈕至擰緊,確保轉(zhuǎn)頭與驅(qū)動軸固定。離心結(jié)束后,松開圓形中心旋鈕,可以把轉(zhuǎn)頭從離心腔整體拿出至生物安全柜時,此時依然可以保持轉(zhuǎn)頭內(nèi)樣品處于嚴(yán)格的密封狀態(tài)。
普通單鎖蓋轉(zhuǎn)頭,適用于離心無生物安全風(fēng)險的普通常規(guī)生物學(xué)、醫(yī)學(xué)和普通理化實(shí)驗(yàn)材料。

2、適配離心瓶
JLA-16.250、JA-14角轉(zhuǎn)頭適配250mL廣口平底(圓底)離心瓶356013、356011。瓶體主體部分為半透明聚丙烯(polypropylene, PPCO)材質(zhì)或透明聚碳酸酯(Polycarbonate,PC)材質(zhì),尺寸(直徑×長度):62×120 mm。瓶蓋為Oak Ridge密封蓋組件(Cap Assemblies),蓋頂部的駝峰樣加強(qiáng)結(jié)構(gòu)既是其典型外觀標(biāo)志,也方便離心瓶提取操作。瓶蓋內(nèi)側(cè)固定有硅膠墊片(silicone gasket)。正常使用情況下,可確保超過10000xg的常溫或低溫離心而無泄漏。瓶蓋側(cè)面為圓滑突起,便于旋緊和開蓋。
JA-14完全兼容JLA16.250轉(zhuǎn)頭的全部適配器。此外,通過添加230mL尖底離心瓶專用瓶墊356983,JA-14可支持用于Beckman、BD、Corning等第三方制造商提供的230mL尖底離心瓶離心。
